Description

Technical Field

[0001] The invention belongs to the technical field of organic wastewater treatment equipment, and particularly relates to high-concentration organic wastewater treatment equipment and a wastewater treatment method. Background Art

[0002] High-concentration organic wastewater treatment equipment is used to treat wastewater with a high organic matter concentration, usually referring to wastewater with a COD value of more than 2000 mg / L. The main goal of organic wastewater treatment equipment is to remove pollutants, reduce toxicity, improve biodegradability, and achieve standard discharge or reuse. This type of wastewater is commonly found in the chemical, pharmaceutical, food, printing and dyeing industries, and has the characteristics of complex composition, high pollutant concentration, and poor biodegradability.

[0003] The main types of high-concentration organic wastewater treatment equipment include: anaerobic treatment equipment, aerobic treatment equipment, physicochemical treatment equipment, deep treatment equipment and integrated treatment systems. Their characteristics are high efficiency, energy saving, compact structure, strong adaptability and environmental protection and efficiency.

[0004] The comprehensive treatment system is an integrated system, such as: "pretreatment + anaerobic + aerobic + deep treatment". In the comprehensive treatment system, pretreatment is usually carried out to achieve the purpose of improving treatment effect and efficiency. For example, grids and screens can be used to remove suspended matter (such as fiber, gravel) and sedimentation, etc., which can be used as pretreatment equipment.

[0005] Suspended matter is the main cause of water turbidity and a key pollution indicator. After organic suspended matter settles, it is prone to anaerobic fermentation, releasing toxic gases such as hydrogen sulfide, leading to deterioration of water quality.

[0006] Most organic wastewater contains suspended matter, which will be cleaned or eliminated in the pretreatment. At present, chemical treatment is mostly used. However, when the chemical treatment is not sufficient, there will still be residual suspended matter. If the dosage of the agent is increased, the cost will increase significantly, so most people will choose to add a screen filtration treatment step.

[0007] At present, when organic wastewater is filtered through a screen, suspended matter will be filtered by the screen. However, most existing screens cannot be self-cleaned and require regular maintenance and cleaning by staff, which has high maintenance costs. At the same time, suspended matter gradually adheres to the screen over time, which will gradually reduce the circulation efficiency of the screen, thereby reducing the pretreatment efficiency of organic wastewater and even causing the risk of blockage, which is not conducive to long-term use.

[0008] The information disclosed in this background technology section is only intended to enhance understanding of the overall background of the invention and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art. Summary of the Invention

[0009] The purpose of the present invention is to provide a high-concentration organic wastewater treatment equipment and wastewater treatment method, which can solve the problem that during the pretreatment of existing organic wastewater, the suspended matter will adhere to the screen over time, gradually reduce the circulation efficiency, and even cause the risk of screen clogging.

[0010] In order to achieve the above object, a specific embodiment of the present invention provides the following technical solutions:

[0015] A centrifugal collecting mechanism is installed on the rotating installation pipe. The centrifugal collecting mechanism includes a centrifugal collecting bin. A centrifugal collecting net is fixedly installed on the centrifugal collecting bin. Centrifugal conveying parts are arranged in the centrifugal collecting bin and the centrifugal collecting net.

[0016] In one or more embodiments of the present invention, a rotating positioning ring is fixedly installed on the side of the rotating filter screen away from the rotating closing plate, which facilitates the fixation of the rotating filter screen, reduces damage to the rotating filter screen, improves the stability of the rotating filter screen, and facilitates the rotation of the rotating filter screen, reducing the probability of damage to the rotating filter screen during rotation;

[0017] A rotating baffle is fixedly installed in the rotating installation pipe, which can locate the position of the rotating positioning ring, reducing the probability of shaking of the rotating filter screen during rotation, further improving the stability of the rotating filter screen, reducing the probability of the rotating filter screen detaching, and ensuring the balance of the rotating filter screen;

[0018] A rotary seal is installed between the rotary baffle plate and the rotary positioning ring, which improves the sealing between the rotary positioning ring and the rotary baffle plate, reduces the possibility of high-concentration organic wastewater leaking through the gap between the rotary positioning ring and the rotary baffle plate, and avoids the situation where suspended matter cannot be processed by the rotary filter screen;

[0019] A rotary motor is fixedly mounted on the rotary mounting pipe, which can drive the rotation of the rotary driving gear, providing corresponding power for the rotation of the rotary driving gear, making the rotation of the rotary driving gear more controllable and the rotation of the rotary filter screen more stable.

[0020] In one or more embodiments of the present invention, the rotary motor is arranged to penetrate the rotary installation pipe, which facilitates the installation of the rotary driving gear and provides corresponding space for the installation of the rotary driving gear, so that the rotary driving gear can better mesh with the rotary driven gear;

[0021] A rotating bearing is installed between the rotating motor and the rotating installation pipe, which reduces the friction between the rotating motor and the rotating installation pipe, increases the service life of the rotating motor and the rotating installation pipe, and reduces damage to the rotating installation pipe and the rotating motor;

[0022] A rotating driving gear is fixedly mounted on the rotating motor, which can drive the rotation of the rotating driven gear, providing corresponding power for the rotation of the rotating driven gear. By meshing with the rotating driven gear, the rotating driven gear can drive the rotating filter screen to rotate. The rotating driving gear meshes with the rotating driven gear.

[0023] In one or more embodiments of the present invention, the pressure collection pipe is connected to the pressure collection frame, so that the suspended matter and high-concentration organic wastewater collected by the pressure collection frame can enter the pressure collection pipe, and the suspended matter and high-concentration organic wastewater can enter the centrifugal collection bin through the pressure collection pipe;

[0024] The pressure-type boosting bin is provided with a flushing groove, which can flush the rotary filter screen with the high-concentration organic wastewater in the pressure-type boosting bin, so that the suspended matter adhering to the rotary filter screen can be flushed off and the suspended matter can be flushed into the pressure-type collection pipe, thereby improving the collection effect of the pressure-type collection frame on the suspended matter;

[0025] The pressure-type collecting pipe is arranged to pass through the rotating closing plate and the rotating driven gear, thereby improving the balance of the rotating closing plate and the rotating driven gear, and can also position the rotating closing plate and the rotating driven gear, thereby reducing the probability of the rotating closing plate and the rotating driven gear being separated;

[0026] A pressure bearing is installed between the pressure collecting pipe, the rotating closing plate and the rotating driven gear. When the rotating closing plate and the rotating driven gear rotate, the friction between the pressure collecting pipe and the rotating closing plate and the rotating driven gear can be reduced, thereby improving the service life of the rotating closing plate, the rotating driven gear and the pressure collecting pipe.

[0027] In one or more embodiments of the present invention, a pressure-type positioning frame and a pressure-type positioning ring are fixedly installed at both ends of the pressure-type collection pipe. The pressure-type positioning frame and the pressure-type positioning ring can position the pressure-type collection pipe, thereby reducing the probability of position deviation of the pressure-type collection pipe and ensuring the balance of the pressure-type collection pipe. The pressure-type positioning frame and the pressure positioning ring are both fixedly installed with the rotating installation pipe.

[0028] In one or more embodiments of the present invention, the pressure water pump is arranged to penetrate the rotating installation pipe, and can continuously inject the high-concentration organic wastewater extracted from the wastewater treatment tank into the pressure boosting chamber, thereby increasing the water pressure in the pressure boosting chamber, thereby improving the flushing efficiency of the pressure boosting chamber on the rotating filter screen, and at the same time providing a corresponding flow channel for the high-concentration organic wastewater;

[0029] The pressure-type boosting chamber is fixedly installed with the rotating installation pipe, and the pressure-type water pump is connected to the pressure-type boosting chamber, so that the high-concentration organic wastewater injected by the pressure-type water pump can enter the pressure-type boosting chamber, so that the high-concentration organic wastewater in the pressure-type boosting chamber can be replenished at any time;

[0030] A pressure extraction pipe is fixedly installed on the pressure water pump, and the pressure water pump can extract high-concentration organic wastewater in the wastewater treatment tank through the pressure extraction pipe, so that the pretreated water in the wastewater treatment tank can be continuously injected into the pressure boosting tank.

[0031] In one or more embodiments of the present invention, the centrifugal collection chamber is arranged to penetrate the rotating installation pipe, which facilitates the installation of the centrifugal collection net and reduces the probability of high-concentration organic wastewater in the rotating installation pipe flowing into the centrifugal collection chamber, thereby reducing the probability of the centrifugal collection net being blocked by external suspended matter.

[0032] The pressure collection pipe is arranged to pass through the centrifugal collection bin, so that the suspended solids and high-concentration organic wastewater collected in the pressure collection pipe can enter the centrifugal collection bin, connecting the pressure collection pipe and the centrifugal collection bin;

[0033] A centrifugal barrier chamber is provided outside the centrifugal collection net, which can continuously collect high-concentration organic wastewater, reduce the probability of high-concentration organic wastewater being thrown out, and enable high-concentration organic wastewater to flow back into the rotating installation pipe. The centrifugal barrier chamber is fixedly installed with the rotating installation pipe.

[0034] In one or more embodiments of the present invention, a reflux groove is drilled on the rotatable installation pipe to facilitate the reflux of high-concentration organic wastewater, so that the high-concentration organic wastewater will not directly enter the wastewater treatment tank without being treated;

[0035] The centrifugal barrier bin is fixedly mounted with a centrifugal cleaning bin, which can collect suspended solids, making it easier for workers to clean up and reducing their workload. At the same time, it reduces the possibility of suspended solids re-entering the wastewater collection tank.

[0036] A centrifugal connecting ring is installed between the centrifugal cleaning chamber and the centrifugal collecting net, connecting the centrifugal cleaning chamber and the centrifugal collecting net so that the suspended matter in the centrifugal collecting net can enter the centrifugal cleaning chamber through the centrifugal connecting ring;

[0037] A centrifugal motor is fixedly installed on the centrifugal cleaning bin, which can drive the rotation of the centrifugal conveying member, providing corresponding power for the rotation of the centrifugal conveying member, so that the centrifugal conveying member can generate centrifugal force through continuous rotation, so that high-concentration organic wastewater in the centrifugal collection net can be thrown out, and at the same time, the centrifugal conveying member can transport suspended matter into the centrifugal cleaning bin.

[0038] In one or more embodiments of the present invention, the centrifugal connecting ring and the centrifugal motor are both arranged through the centrifugal cleaning chamber, connecting the centrifugal cleaning chamber and the centrifugal connecting ring, facilitating the entry of suspended matter into the centrifugal cleaning chamber, and facilitating the installation of the centrifugal motor and the connection between the centrifugal motor and the centrifugal conveying element;

[0039] The centrifugal motor is fixedly mounted on the centrifugal conveying member, which facilitates the centrifugal motor to drive the centrifugal conveying member to rotate, and provides corresponding power for the rotation of the centrifugal conveying member;

[0040] The centrifugal connecting ring, centrifugal collecting bin and centrifugal collecting net are all matched with the centrifugal conveying element, thereby improving the conveying efficiency of the centrifugal conveying element, while reducing the probability of suspended matter and high-concentration organic wastewater being unable to be conveyed, so that high-concentration organic wastewater can be better thrown out of the centrifugal collecting net.

[0041] A wastewater treatment method for a high-concentration organic wastewater treatment device comprises the following steps:

[0042] S1. When high-concentration organic wastewater flows from the wastewater collection tank into the wastewater treatment tank, it will first enter the rotating installation pipe. Due to the obstruction of the rotating baffle plate, the high-concentration organic wastewater can only pass through the rotating filter screen, which pre-treats the suspended solids in it;

[0043] S2. The high-concentration organic wastewater after pretreatment will flow into the wastewater treatment pool through the rotating installation pipe for subsequent treatment, and the rotating motor will drive the rotating filter screen to rotate through the rotating driven gear, so that the rotating filter screen can pre-treat the high-concentration organic wastewater by rotating, thereby avoiding clogging of the rotating filter screen;

[0044] S3. At the same time, the rotating filter screen can rotate the suspended matter adhering to the bottom to the top of the rotating filter screen. At this time, the pressure water pump extracts the high-concentration organic wastewater that has been pre-treated in the wastewater treatment tank through the pressure extraction pipe and injects the high-concentration organic wastewater into the pressure boosting tank;

[0045] S4. The pressure-type boosting chamber achieves the purpose of increasing water pressure by injecting more water than the water output. The high water pressure and the scouring groove excavated on the lower side of the pressure-type boosting chamber scour the top of the rotating filter screen. The rotating filter screen is scoured and the suspended matter attached to it is washed away;

[0046] S5. At this time, the pressure collection frame receives the dropped suspended solids and the high-concentration organic wastewater, which flows into the centrifugal collection chamber through the guidance of the pressure collection pipe.

[0047] S6. Start the centrifugal motor to rotate the centrifugal conveyor at a high speed, and continuously transport the suspended solids and high-concentration organic wastewater at the bottom of the centrifugal collection bin upward, so that the suspended solids and high-concentration organic wastewater in the pressure collection pipe can continuously flow into the centrifugal collection bin;

[0048] S7. When suspended matter and high-concentration organic wastewater pass through the centrifugal collection net, due to the assistance of centrifugal force and the filtration of suspended matter by the centrifugal collection net, the high-concentration organic wastewater can be thrown out and the suspended matter can be retained in the centrifugal collection net. It is then transported to the centrifugal cleaning bin by the centrifugal conveyor for collection. The staff only needs to clean the centrifugal cleaning bin regularly.

[0049] Compared with the prior art, the high-concentration organic wastewater treatment equipment and wastewater treatment method of the present invention enable the screen to be self-cleaning through the setting of corresponding mechanisms, reducing staff maintenance and maintenance costs. At the same time, it reduces the adhesion of suspended matter to the screen and reduces the chance of a decrease in the screen circulation efficiency, thereby improving the pretreatment efficiency of organic wastewater and reducing the risk of blockage, making it more suitable for long-term use.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0063] like Figures 1 to 9 As shown, a high-concentration organic wastewater treatment device and wastewater treatment method in one embodiment of the present invention includes: a wastewater collection tank 1, a rotary pretreatment mechanism 2, a pressure cleaning mechanism 3 and a centrifugal collection mechanism 4.

[0064] like Figures 1 to 5 As shown, a wastewater treatment tank 101 is provided on one side of the wastewater collection tank 1, and a rotary pretreatment mechanism 2 is provided in the wastewater collection tank 1. The rotary pretreatment mechanism 2 includes a rotary installation pipe 201, which can connect the wastewater collection tank 1 and the wastewater treatment tank 101.

[0066] In addition, a rotating closing plate 203 is fixedly installed on one side of the rotating installation pipe 201, which can close one side of the rotating filter screen 202, reducing the probability of high-concentration organic wastewater being discharged through the gap, and improving the treatment effect of the rotating filter screen 202 on high-concentration organic wastewater.

[0067] In addition, a rotating driven gear 204 is fixedly installed on the side of the rotating closing plate 203 away from the rotating filter screen 202, which can be driven by the rotating driving gear 210 to rotate, thereby driving the rotation of the rotating filter screen 202, providing corresponding power for the rotation of the rotating filter screen 202, making the rotation of the rotating filter screen 202 more stable.

[0068] like Figures 1 to 6 As shown, a rotating positioning ring 205 is fixedly installed on the side of the rotating filter screen 202 away from the rotating closing plate 203, which facilitates the fixation of the rotating filter screen 202, reduces the damage to the rotating filter screen 202, improves the stability of the rotating filter screen 202, and at the same time, facilitates the rotation of the rotating filter screen 202, reducing the chance of damage to the rotating filter screen 202 during rotation.

[0069] Among them, a rotating baffle plate 206 is fixedly installed in the rotating installation pipe 201, which can locate the position of the rotating positioning ring 205, reducing the probability of shaking of the rotating filter screen 202 during rotation, thereby further improving the stability of the rotating filter screen 202, reducing the probability of the rotating filter screen 202 detaching, and ensuring the balance of the rotating filter screen 202.

[0070] In addition, a rotating seal 207 is installed between the rotating baffle plate 206 and the rotating positioning ring 205, which improves the sealing between the rotating positioning ring 205 and the rotating baffle plate 206, reduces the possibility of high-concentration organic wastewater leaking through the gap between the rotating positioning ring 205 and the rotating baffle plate 206, and avoids the situation where suspended matter cannot be processed by the rotating filter screen 202.

[0071] In addition, a rotary motor 208 is fixedly mounted on the rotary mounting pipe 201, which can drive the rotation of the rotary driving gear 210, providing corresponding power for the rotation of the rotary driving gear 210, making the rotation of the rotary driving gear 210 more controllable and the rotation of the rotary filter screen 202 more stable.

[0072] like Figures 1 to 7As shown, the rotary motor 208 is arranged to penetrate the rotary installation pipe 201, which facilitates the installation of the rotary driving gear 210 and provides corresponding space for the installation of the rotary driving gear 210, so that the rotary driving gear 210 can better mesh with the rotary driven gear 204.

[0073] Among them, a rotating bearing 209 is installed between the rotating motor 208 and the rotating mounting pipe 201, which reduces the friction between the rotating motor 208 and the rotating mounting pipe 201, improves the service life of the rotating motor 208 and the rotating mounting pipe 201, and reduces the damage to the rotating mounting pipe 201 and the rotating motor 208.

[0074] In addition, a rotating driving gear 210 is fixedly mounted on the rotating motor 208, which can drive the rotation of the rotating driven gear 204, providing corresponding power for the rotation of the rotating driven gear 204. By meshing with the rotating driven gear 204, the rotating driven gear 204 can drive the rotating filter screen 202 to rotate, and the rotating driving gear 210 is meshed with the rotating driven gear 204.

[0075] like Figures 1 to 4 As shown, a pressure-type cleaning mechanism 3 is provided in the rotating filter screen 202. The pressure-type cleaning mechanism 3 includes a pressure-type collecting pipe 301, which can connect the pressure-type collecting frame 302 and the centrifugal collecting bin 401. When the pressure-type collecting frame 302 collects high-concentration organic wastewater and suspended matter, they can flow into the centrifugal collecting bin 401 through the pressure-type collecting pipe 301.

[0076] In addition, a pressure-type collection frame 302 is fixedly installed on the pressure-type collection pipe 301, which can increase the collection area for high-concentration organic wastewater and improve the collection efficiency of suspended matter.

[0077] In addition, a pressure-type boosting chamber 303 is provided on the pressure-type collection frame 302, and high-concentration organic wastewater can be continuously injected into the pressure-type boosting chamber 303 through a pressure-type water pump 304, so that the water pressure in the pressure-type boosting chamber 303 increases, so that the high-concentration organic wastewater discharged from the pressure-type boosting chamber 303 can flush the rotating filter screen 202.

[0078] Among them, a pressure water pump 304 is fixedly installed on the rotating installation pipe 201, which can extract high-concentration organic wastewater in the wastewater treatment tank 101 through the pressure extraction pipe 308, so that the high-concentration organic wastewater in the pressure boosting chamber 303 can be replenished at any time.

[0079] like Figures 1 to 5As shown, the pressure collection pipe 301 is connected to the pressure collection frame 302, so that the suspended matter and high-concentration organic wastewater collected by the pressure collection frame 302 can enter the pressure collection pipe 301, and the suspended matter and high-concentration organic wastewater can enter the centrifugal collection bin 401 through the pressure collection pipe 301.

[0080] Among them, a flushing groove is dug on the pressure boosting chamber 303, which can flush the rotating filter screen 202 with the high-concentration organic wastewater in the pressure boosting chamber 303, so that the suspended matter adhered to the rotating filter screen 202 can be flushed down, and the suspended matter can be flushed into the pressure collection pipe 301, thereby improving the collection effect of the pressure collection frame 302 on suspended matter.

[0081] In addition, the pressure collection pipe 301 is set through the rotating closing plate 203 and the rotating driven gear 204, which improves the balance of the rotating closing plate 203 and the rotating driven gear 204, and at the same time can position the rotating closing plate 203 and the rotating driven gear 204, reducing the probability of the rotating closing plate 203 and the rotating driven gear 204 disengaging.

[0082] In addition, a pressure bearing 305 is installed between the pressure collection pipe 301, the rotating closing plate 203 and the rotating driven gear 204. When the rotating closing plate 203 and the rotating driven gear 204 rotate, the friction between the pressure collection pipe 301 can be reduced, thereby improving the service life of the rotating closing plate 203, the rotating driven gear 204 and the pressure collection pipe 301.

[0083] like Figures 1 to 3 As shown, a pressure-type positioning frame 306 and a pressure-type positioning ring 307 are fixedly installed at both ends of the pressure-type collection pipe 301. The pressure-type positioning frame 306 and the pressure-type positioning ring 307 can position the pressure-type collection pipe 301, thereby reducing the probability of position deviation of the pressure-type collection pipe 301 and ensuring the balance of the pressure-type collection pipe 301. The pressure-type positioning frame 306 and the pressure-type positioning ring 307 are both fixedly installed with the rotatable installation pipe 201.

[0084] like Figures 1 to 8 As shown, the pressure water pump 304 is set through the rotating installation pipe 201, which can continuously inject the high-concentration organic wastewater extracted from the wastewater treatment tank 101 into the pressure boosting chamber 303, thereby increasing the water pressure in the pressure boosting chamber 303, thereby improving the flushing efficiency of the pressure boosting chamber 303 on the rotating filter screen 202, and at the same time providing a corresponding circulation channel for the high-concentration organic wastewater.

[0085] In addition, the pressure boosting chamber 303 is fixedly installed with the rotating installation pipe 201, and the pressure water pump 304 is connected to the pressure boosting chamber 303, so that the high-concentration organic wastewater injected by the pressure water pump 304 can enter the pressure boosting chamber 303, so that the high-concentration organic wastewater in the pressure boosting chamber 303 can be replenished at any time.

[0086] In addition, a pressure extraction pipe 308 is fixedly installed on the pressure water pump 304. The pressure water pump 304 can extract high-concentration organic wastewater in the wastewater treatment tank 101 through the pressure extraction pipe 308, so that the pretreated water in the wastewater treatment tank 101 can be continuously injected into the pressure boosting chamber 303.

[0087] like Figures 1 to 8 As shown, a centrifugal collecting mechanism 4 is installed on the rotating installation pipe 201. The centrifugal collecting mechanism 4 includes a centrifugal collecting bin 401, which can collect high-concentration organic wastewater and suspended matter, and at the same time facilitates the rotation of the centrifugal conveying member 403, providing corresponding space for the installation of the centrifugal conveying member 403.

[0088] In addition, a centrifugal collection net 402 is fixedly installed on the centrifugal collection bin 401. When the centrifugal conveying member 403 conveys high-concentration organic wastewater and suspended matter through the centrifugal collection net 402, the centrifugal force generated by the centrifugal conveying member 403 can quickly throw out the high-concentration organic wastewater, while the centrifugal collection net 402 can block the suspended matter.

[0089] Among them, the centrifugal collection bin 401 and the centrifugal collection net 402 are provided with a centrifugal conveying member 403, which can continuously convey high-concentration organic wastewater and suspended matter, and can throw high-concentration organic wastewater out through the centrifugal collection net 402 by centrifugal force. At the same time, by matching with the centrifugal collection net 402, the suspended matter adhered to the inside of the centrifugal collection net 402 can be scraped off, reducing the chance of clogging of the centrifugal collection net 402.

[0090] like Figures 1 to 9 As shown, the centrifugal collection bin 401 is arranged to pass through the rotating installation pipe 201, which facilitates the installation of the centrifugal collection net 402 and reduces the probability of high-concentration organic wastewater in the rotating installation pipe 201 flowing into the centrifugal collection bin 401, thereby reducing the probability of the centrifugal collection net 402 being blocked by external suspended matter.

[0091] Among them, the pressure collection pipe 301 is set through the centrifugal collection bin 401, so that the suspended matter and high-concentration organic wastewater collected in the pressure collection pipe 301 can enter the centrifugal collection bin 401, connecting the pressure collection pipe 301 and the centrifugal collection bin 401.

[0092] In addition, a centrifugal barrier chamber 404 is provided outside the centrifugal collection net 402, which can collect high-concentration organic wastewater, reduce the possibility of leakage of high-concentration organic wastewater, and reduce the probability of high-concentration organic wastewater polluting other places. It can continuously collect high-concentration organic wastewater and reduce the probability of high-concentration organic wastewater being thrown out. The centrifugal barrier chamber 404 is fixedly installed with the rotating installation pipe 201.

[0093] like Figures 1 to 6 As shown, a reflux groove is drilled on the rotatable installation pipe 201 to facilitate the reflux of high-concentration organic wastewater, so that the high-concentration organic wastewater will not directly enter the wastewater treatment tank 101 without being treated.

[0094] Among them, a centrifugal cleaning chamber 405 is fixedly installed on the centrifugal barrier chamber 404, which can collect suspended matter, facilitate cleaning by the staff, reduce the staff's labor work, and at the same time, reduce the possibility of suspended matter entering the wastewater collection tank 1 again.

[0095] In addition, a centrifugal connecting ring 406 is installed between the centrifugal cleaning chamber 405 and the centrifugal collecting net 402, connecting the centrifugal cleaning chamber 405 and the centrifugal collecting net 402, so that the suspended matter in the centrifugal collecting net 402 can enter the centrifugal cleaning chamber 405 through the centrifugal connecting ring 406.

[0096] In addition, a centrifugal motor 407 is fixedly installed on the centrifugal cleaning chamber 405, which can drive the rotation of the centrifugal conveying member 403, providing corresponding power for the rotation of the centrifugal conveying member 403, so that the centrifugal conveying member 403 can generate centrifugal force through continuous rotation, so that the high-concentration organic wastewater in the centrifugal collection net 402 can be thrown out, and at the same time, the centrifugal conveying member 403 can transport suspended matter into the centrifugal cleaning chamber 405.

[0097] like Figures 1 to 5 As shown, the centrifugal connecting ring 406 and the centrifugal motor 407 are both set through the centrifugal cleaning chamber 405, connecting the centrifugal cleaning chamber 405 and the centrifugal connecting ring 406, making it convenient for suspended matter to enter the centrifugal cleaning chamber 405, and at the same time facilitating the installation of the centrifugal motor 407, and facilitating the connection between the centrifugal motor 407 and the centrifugal conveying member 403.

[0098] The centrifugal motor 407 is fixedly installed with the centrifugal conveying member 403 , which facilitates the centrifugal motor 407 to drive the centrifugal conveying member 403 to rotate, and provides corresponding power for the rotation of the centrifugal conveying member 403 .

[0099] In addition, the centrifugal connecting ring 406, the centrifugal collecting chamber 401 and the centrifugal collecting net 402 are all matched with the centrifugal conveying element 403, which improves the conveying efficiency of the centrifugal conveying element 403, while reducing the probability of suspended matter and high-concentration organic wastewater being unable to be transported, so that high-concentration organic wastewater can be better thrown out of the centrifugal collecting net 402.

[0100] A wastewater treatment method for a high-concentration organic wastewater treatment device comprises the following steps:

[0101] S1. When high-concentration organic wastewater flows from the wastewater collection tank 1 into the wastewater treatment tank 101, it first enters the rotating installation pipe 201. Due to the obstruction of the rotating baffle plate 206, the high-concentration organic wastewater can only pass through the rotating filter screen 202, and the rotating filter screen 202 pre-treats the suspended matter therein.

[0102] S2. The high-concentration organic wastewater after pretreatment will flow into the wastewater treatment tank 101 through the rotating installation pipe 201 for subsequent treatment, and the rotating motor 208 will drive the rotation of the rotating filter screen 202 through the rotating driven gear 204, so that the rotating filter screen 202 can pre-treat the high-concentration organic wastewater by rotating, thereby avoiding clogging of the rotating filter screen 202.

[0103] S3. At the same time, the rotating rotary filter screen 202 can rotate the suspended matter adhering to the bottom to the top of the rotating filter screen 202. At this time, the pressure water pump 304 extracts the high-concentration organic wastewater that has been pretreated in the wastewater treatment tank 101 through the pressure extraction pipe 308, and injects the high-concentration organic wastewater into the pressure boosting chamber 303.

[0104] S4. The pressure-type boosting chamber 303 achieves the purpose of increasing water pressure by injecting more water than discharging water. The high water pressure and the flushing groove excavated on the lower side of the pressure-type boosting chamber 303 flush the top of the rotating filter screen 202. When the rotating filter screen 202 is flushed, the suspended matter attached to it will be washed away.

[0105] S5. At this time, the pressure-type collection frame 302 receives the dropped suspended matter and the flushed high-concentration organic wastewater, and guides them through the pressure-type collection pipe 301 to flow into the centrifugal collection bin 401.

[0106] S6. Start the centrifugal motor 407 to rotate the centrifugal conveying member 403 at a high speed, and continuously transport the suspended matter and high-concentration organic wastewater at the bottom of the centrifugal collecting bin 401 upward, so that the suspended matter and high-concentration organic wastewater in the pressure collection pipe 301 can continuously flow into the centrifugal collecting bin 401.

[0107] S7. When the suspended matter and high-concentration organic wastewater pass through the centrifugal collection net 402, due to the assistance of centrifugal force and the filtration of the suspended matter by the centrifugal collection net 402, the high-concentration organic wastewater can be thrown out and the suspended matter can be retained in the centrifugal collection net 402. The suspended matter is then transported to the centrifugal cleaning bin 405 by the centrifugal conveying member 403 for collection. The staff only needs to clean the centrifugal cleaning bin 405 regularly.
