Description

Technical Field

[0001] The present application relates to the field of sewage treatment, and in particular to a sewage treatment device. Background Art

[0002] Wastewater treatment refers to the process of purifying wastewater so that it meets the water quality requirements for discharge into a water body or reuse. Wastewater treatment is generally divided into industrial wastewater treatment and domestic wastewater treatment. Industrial wastewater includes industrial wastewater, agricultural wastewater, and medical wastewater, while domestic wastewater is the wastewater generated in daily life, which refers to a complex mixture of various forms of inorganic and organic matter.

[0003] At present, when treating domestic sewage, flocculants are usually added to the sedimentation tank to make the tiny suspended particles in the water aggregate and form larger flocs. Larger flocs settle faster than tiny suspended particles, which can speed up the sedimentation rate and is beneficial to the filtration effect of sewage. However, the existing flocculants directly add powdered flocculants during the addition process. Iron and aluminum flocculants dissolve slowly in water, resulting in poor flocculant use and affecting the efficiency of flocculation and sedimentation. Summary of the invention

[0004] In order to alleviate the problem of poor use effect of flocculants, the present application provides a sewage treatment device.

[0005] The present application provides a sewage treatment device, which adopts the following technical solution:

[0006] A sewage treatment device comprises a sedimentation tank and a distribution mechanism, wherein the distribution mechanism comprises a liquid storage tank, a delivery pump and a distribution pipe, wherein the liquid storage tank is used to store a flocculant solution, wherein the distribution pipe is vertically inserted into the sedimentation tank from one end of the sedimentation tank away from the ground, wherein one end of the distribution pipe is located in the sedimentation tank, and the other end of the distribution pipe is located on a side of the sedimentation tank away from the ground, wherein the distribution pipe is rotatably connected to the sedimentation tank, wherein the distribution pipe is hollow, wherein the liquid storage tank is communicated with the distribution pipe through the delivery pump, wherein a plurality of groups of discharge structures are arranged on the side wall of the distribution pipe located in the sedimentation tank, wherein the plurality of groups of the discharge structures are arranged at intervals along the axial direction of the distribution pipe, wherein the discharge structure comprises a plurality of discharge channels opened on the side wall of the distribution pipe, wherein one end of the discharge channel is communicated with the inside of the distribution pipe, and the other end of the discharge channel is communicated with the outside of the distribution pipe, wherein the plurality of discharge channels are arranged at equal intervals along the circumference of the distribution pipe, and the discharge direction of the discharge channel is parallel to the tangent direction of the distribution pipe.

[0007] By adopting the above technical scheme, the delivery pump pumps the flocculant solution in the liquid storage tank into the lumen of the distribution pipe. After the flocculant solution enters the lumen of the distribution pipe, it flows into the sedimentation tank from the discharge channel under pressure and mixes with the sewage. A plurality of discharge channels are opened along the circumference of the distribution pipe and the discharge direction of the discharge channel is parallel to the tangent direction of the distribution pipe. When the flocculant is sprayed out from the discharge channel, the distribution pipe is pushed to rotate, so that the distribution pipe rotates in the sedimentation tank to distribute the flocculant more evenly, which accelerates the sedimentation rate of suspended particles in the sewage, shortens the processing time, improves the overall processing efficiency, and alleviates the problem of poor flocculant use effect.

[0008] Optionally, the distance between two adjacent groups of the discharging structures gradually increases from an end of the distributing pipe far from the ground to an end of the distributing pipe close to the ground.

[0009] By adopting the above technical solution, the discharge structure is more densely distributed at the end of the sedimentation tank away from the ground. After the flocculant is mixed with the sewage, the tiny suspended particles in the sewage are aggregated to form larger flocs. The flocs settle downward under the action of gravity. By spraying more flocculant solution from the end of the sedimentation tank away from the ground, the flocculation reaction between the flocculant and the sewage is more complete, thereby further improving the efficiency of flocculation sedimentation.

When the flocculant is sprayed out from the discharge channel, the distribution pipe is pushed to rotate. The stirring blades rotate under the drive of the distribution pipe, thereby stirring the sewage in the sedimentation tank, so that the flocculant solution and the sewage are mixed more evenly; in the sedimentation process, the addition of the flocculant solution will be stopped after a certain amount is added, and air is transported into the tube cavity of the distribution pipe by using the air supply component.

[0013] By adopting the above technical solution, the air inlet pipe is coaxially arranged in the fabric pipe, and an annular fabric channel is formed between the outer wall of the air inlet pipe and the inner wall of the fabric pipe, so as to improve the jet effect of the flocculant solution without changing the power of the delivery pump; in the fabric process, the air pump is used to pump air into the air inlet pipe, and the airflow ejected from the air outlet can increase the turbulence in the sewage, promote the mixing of the suspended particles in the sewage and the flocculant, and accelerate the occurrence of the flocculation reaction; in addition, before adding the flocculant solution to the sedimentation tank by using the fabric pipe, the air pump is started first, and the sewage in the fabric channel is discharged by the air ejected from the air outlet, so as to reduce the possibility of flocculation reaction between the flocculant solution and the sewage in the fabric channel, thereby ensuring the smooth flow of the fabric channel.

[0014] Optionally, the distance between two adjacent groups of the air outlet structures gradually decreases from an end of the air inlet pipe far from the ground to an end of the air inlet pipe close to the ground.

[0015] By adopting the above technical solution, the air outlet structure is distributed more densely at the end of the sedimentation tank close to the ground, so that more air flows out from the discharge channel close to the bottom of the sedimentation tank. The air forms bubbles in the sewage and floats up, making the flocculant solution more evenly distributed in the sewage, promoting the mixing of suspended particles in the sewage and the flocculant, and accelerating the occurrence of flocculation reaction.

[0016] Optionally, the air outlet of the air pump is connected to the air inlet pipe, and the air inlet of the air pump is provided with a three-way control valve, the outlet of the three-way control valve is connected to the air inlet of the air pump, one inlet of the three-way control valve is connected to the atmosphere, and the other inlet of the three-way control valve is connected to an ozone generating mechanism.

[0021] By adopting the above technical solution, an adjusting retaining ring is arranged in the distribution pipe, and when the air inlet pipe is used to transport ozone into the sedimentation box for disinfection, the adjusting retaining ring is driven by the electric push rod to move in the direction away from the ground, thereby closing the air outlet and the discharge channel near the end of the air inlet pipe away from the ground, so that the ozone entering the air inlet pipe enters the sedimentation box through the air outlet and the discharge channel near the bottom of the sedimentation box, and the ozone is dissipated upward from a position near the bottom of the sedimentation box, thereby improving the sterilization effect on the sewage in the sedimentation box.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] The flocculant solution in the liquid storage tank is pumped into the lumen of the distribution pipe by using a delivery pump. After the flocculant solution enters the lumen of the distribution pipe, it flows into the sedimentation tank from the discharge channel under pressure to mix with the sewage. A plurality of discharge channels are opened along the circumference of the distribution pipe, and the discharge direction of the discharge channel is tangent to the distribution pipe. When the flocculant is sprayed out from the discharge channel, the distribution pipe is pushed to rotate, so that the distribution pipe rotates in the sedimentation tank to distribute the flocculant more evenly, which accelerates the sedimentation speed of suspended particles in the sewage, shortens the treatment time, improves the overall treatment efficiency, and alleviates the problem of poor flocculant use effect.

[0024] By arranging stirring blades on the side wall of the distribution pipe, the distribution pipe is pushed to rotate when the flocculant is sprayed out from the discharge channel. The stirring blades rotate under the drive of the distribution pipe, thereby stirring the sewage in the sedimentation tank, so that the flocculant solution and the sewage are mixed more evenly. During the sedimentation process, the flocculant solution will stop adding after a certain amount is added, and the air supply component is used to transport air into the tube cavity of the distribution pipe.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0035] The present application embodiment discloses a sewage treatment device. Figure 1 and Figure 2 A sewage treatment device includes a sedimentation tank 100 and a distribution mechanism 200. The sedimentation tank 100 is a vertically arranged cylindrical structure, and a water inlet 140 and a water outlet 150 are provided on the side wall of the sedimentation tank 100, and the water inlet 140 is located above the water outlet 150. The distribution mechanism 200 includes a liquid storage tank 210, a delivery pump 220 and a distribution pipe 230. The liquid storage tank 210 is used to store the configured flocculant solution. The distribution pipe 230 is vertically inserted into the sedimentation tank 100 from the end of the sedimentation tank 100 away from the ground, and the distribution pipe 230 is coaxially arranged with the sedimentation tank 100. The lower end of the distribution pipe 230 is located in the sedimentation tank 100, and the upper end of the distribution pipe 230 is located outside the top of the sedimentation tank 100, and the distribution pipe 230 is rotatably connected with the sedimentation tank 100. The distribution pipe 230 is hollow, and the liquid storage tank 210 is connected to the distribution pipe 230 through the delivery pump 220. A plurality of groups of discharge structures are arranged on the side wall of the distribution pipe 230 located in the sedimentation tank 100, and the plurality of groups of discharge structures are arranged at intervals along the axial direction of the distribution pipe 230. The discharge structure includes a plurality of discharge channels 231 opened on the side wall of the distribution pipe 230, one end of the discharge channel 231 is connected to the inside of the distribution pipe 230, and the other end of the discharge channel 231 is connected to the outside of the distribution pipe 230. The plurality of discharge channels 231 are arranged at equal intervals along the circumference of the distribution pipe 230, and the discharge direction of the discharge channel 231 is parallel to the tangent direction of the distribution pipe 230.

[0036] A stirring blade 240 is installed on the side wall of the distribution pipe 230, and the stirring blade 240 is located inside the sedimentation box 100. The distribution pipe 230 is connected to an air supply component 250, which is used to transport air into the tube cavity of the distribution pipe 230. The top of the sedimentation box 100 is provided with an exhaust port 110.

[0037] When the sewage in the sedimentation tank 100 is subjected to flocculation and sedimentation treatment, air is first delivered to the lumen of the distribution pipe 230 through the air supply component 250, and the sewage in the lumen is discharged by air, so as to reduce the possibility of flocculation reaction between the flocculant solution and the sewage in the lumen, and ensure the smooth flow of the lumen. Then, the flocculant solution in the liquid storage tank 210 is pumped into the lumen of the distribution pipe 230 through the delivery pump 220. After the flocculant solution enters the lumen of the distribution pipe 230, it flows into the sedimentation tank 100 from the discharge channel 231 under the action of pressure and mixes with the sewage. When the flocculant is sprayed out from the discharge channel 231, it pushes the distribution pipe 230 to rotate, so that the distribution pipe 230 rotates and distributes in the sedimentation tank 100, and the flocculant solution is more evenly distributed in the sedimentation tank 100, which accelerates the sedimentation speed of suspended particles in the sewage, shortens the treatment time, improves the overall treatment efficiency, and alleviates the problem of poor flocculant use effect.

[0038] Reference Figure 2 and Figure 3 The stirring blade 240 rotates under the drive of the distribution pipe 230, thereby stirring the sewage in the sedimentation tank 100, so that the flocculant solution and the sewage are mixed more evenly. During the sedimentation process, the flocculant solution will stop adding after a certain amount is added, and the air supply component 250 is used to transport air into the tube cavity of the distribution pipe 230, and the air is sprayed into the sewage from the discharge channel 231, thereby driving the distribution pipe 230 to rotate, ensuring the stirring effect of the stirring blade 240 on the sewage.

[0039] From the end of the distribution pipe 230 far from the ground to the end of the distribution pipe 230 close to the ground, the distance between two adjacent groups of discharge structures gradually increases. The discharge structures are more densely distributed in the area close to the top of the sedimentation tank 100. After the flocculant is mixed with the sewage, the tiny suspended particles in the sewage are gathered to form larger flocs, which settle downward under the action of gravity. By spraying more flocculant solution from the area close to the top of the sedimentation tank 100, the flocculation reaction between the flocculant and the sewage is more complete, further improving the efficiency of flocculation and sedimentation.

[0040] Reference Figure 2 and Figure 3The air supply assembly 250 includes an air inlet pipe 251 and an air pump 252. The air inlet pipe 251 is inserted into the fabric pipe 230 from the end of the fabric pipe 230 away from the ground, and one end of the air inlet pipe 251 is located in the tube cavity of the fabric pipe 230. The air inlet pipe 251 is coaxially rotatably connected with the fabric pipe 230. The air inlet pipe 251 is hollow, and the air pump 252 is connected to the inside of the air inlet pipe 251. A plurality of groups of air outlet structures are arranged on the side wall of the air inlet pipe 251 located in the tube cavity of the fabric pipe 230. The plurality of groups of air outlet structures are arranged at intervals along the axial direction of the air inlet pipe 251. From the end of the air inlet pipe 251 away from the ground to the end of the air inlet pipe 251 close to the ground, the distance between two adjacent groups of air outlet structures gradually decreases. The air outlet structure includes a plurality of air outlet holes 253 opened on the side wall of the air inlet pipe 251 . The air outlet holes 253 penetrate the side wall of the air inlet pipe 251 . The plurality of air outlet holes 253 are arranged at equal intervals along the circumference of the air inlet pipe 251 .

[0041] The air inlet pipe 251 is coaxially arranged in the fabric pipe 230, and an annular fabric channel is formed between the outer wall of the air inlet pipe 251 and the inner wall of the fabric pipe 230, which improves the jet effect of the flocculant solution without changing the power of the delivery pump 220. During the fabric process, the air pump 252 is used to pump air into the air inlet pipe 251, and the airflow ejected from the air outlet 253 can increase the turbulence in the sewage, promote the mixing of suspended particles in the sewage and flocculants, and accelerate the occurrence of flocculation reaction. The air outlet structure is more densely distributed in the area at the bottom of the sedimentation tank 100, so that more air flows out from the discharge channel 231 near the bottom of the sedimentation tank 100, and the air forms bubbles in the sewage and floats up, so that the flocculant solution is more evenly distributed in the sewage, promotes the mixing of suspended particles in the sewage and flocculants, and accelerates the occurrence of flocculation reaction.

[0042] Reference Figure 1 and Figure 4 The air outlet of the air pump 252 is connected to the air inlet pipe 251, and the air inlet of the air pump 252 is provided with a three-way control valve 254, and the outlet of the three-way control valve 254 is connected to the air inlet of the air pump 252. One inlet of the three-way control valve 254 is connected to the atmosphere, and the other inlet of the three-way control valve 254 is connected to the ozone generating mechanism 300.

[0043] The ozone generating mechanism 300 is connected to the air pump 252 through the three-way control valve 254. After the flocculant solution is introduced for a certain period of time, the three-way control valve 254 is adjusted to connect the ozone generating mechanism 300 with the air pump 252. The ozone generated by the ozone generating mechanism 300 is pumped into the air inlet pipe 251 by the air pump 252, and the ozone is injected into the sewage through the air outlet 253 and the discharge channel 231, so as to disinfect the sewage after precipitation and mix the ozone and the sewage evenly.

[0044] The material distributing pipe 230 is connected with an adjusting assembly 260. The adjusting assembly 260 includes an adjusting retaining ring 261 for closing the air outlet 253 and the material discharging channel 231. The adjusting retaining ring 261 is sleeved on the outside of the air inlet pipe 251, and the adjusting retaining ring 261 is slidably connected to the inner wall of the material distributing pipe 230. An electric push rod 262 is provided at one end of the sedimentation box 100 close to the ground, and the piston rod of the electric push rod 262 passes through the sedimentation box 100 and is fixedly connected to the adjusting retaining ring 261, and the piston rod of the electric push rod 262 is sealed and slidably connected to the sedimentation box 100.

[0045] By installing an adjusting retaining ring 261 in the fabric pipe 230, when ozone is transported into the sedimentation tank 100 for disinfection by using the air inlet pipe 251, the electric push rod 262 drives the adjusting retaining ring 261 to move toward the top of the sedimentation tank 100, and the adjusting retaining ring 261 is used to close the air outlet hole 253 and the discharge channel 231 near the top area of ​​the sedimentation tank 100, so that the ozone entering the air inlet pipe 251 enters the sedimentation tank 100 through the air outlet hole 253 and the discharge channel 231 near the bottom area of ​​the sedimentation tank 100, and the ozone escapes upward from a position near the bottom of the sedimentation tank 100, so that the reaction between ozone and sewage is more complete, thereby improving the sterilization effect on the sewage in the sedimentation tank 100.

[0046] Reference Figure 2 The sedimentation tank 100 includes a reaction part 120 and a sedimentation part 130. The sedimentation part 130 is located below the reaction part 120, and the inner diameter of the sedimentation part 130 gradually decreases from one end close to the reaction part 120 to the end away from the reaction part 120. The discharge channel 231 and the air outlet 253 are both located on the side of the sedimentation part 130 away from the ground. The sludge generated after the flocculation reaction accumulates in the sedimentation part 130 at the bottom of the sedimentation tank 100 under the action of gravity. By arranging the discharge channel 231 and the air outlet 253 above the sedimentation part 130, the possibility of dispersing the precipitated sludge when ozone disinfection is introduced into the sedimentation tank 100 is reduced, thereby reducing the influence of sewage disinfection on the sedimentation effect.
