Description

Technical Field

[0001] The present invention relates to the technical field of wastewater, and in particular to an environmentally friendly and efficient wastewater treatment device. Background Art

[0002] An environmentally friendly, high-efficiency wastewater treatment device is a comprehensive treatment facility designed based on the principles of physical, chemical, and biological synergy. It typically integrates pretreatment, core purification, advanced treatment, and resource recovery modules. It removes large impurities through pretreatment processes such as grid interception and sedimentation separation. It utilizes core technologies such as catalytic oxidation, membrane separation, and biological treatment (anaerobic-aerobic combined processes) to degrade pollutants such as organic matter, heavy metals, and nitrogen and phosphorus. Advanced treatment processes such as activated carbon adsorption and ultraviolet disinfection ensure that effluent quality meets standards. Furthermore, it is equipped with sludge dewatering and heat recovery systems to achieve waste reduction and energy recycling. For example, the high-efficiency wastewater treatment method and dedicated treatment device disclosed in Chinese Patent Publication No. CN101284703A.

[0003] In existing environmentally friendly and efficient wastewater treatment devices, a fixed amount of anaerobic or aerobic biomass is usually added during the biological treatment process. This makes it impossible to synchronously increase or decrease the anaerobic or aerobic biomass based on the treatment of the corresponding organic matter in the wastewater by the anaerobic or aerobic organisms in the biological treatment process, thus causing an imbalance between treatment efficiency and energy consumption.

[0004] That is, when the concentration of organic matter in the wastewater fluctuates greatly, the fixed biomass can easily lead to the inability to fully degrade the high-concentration wastewater, resulting in substandard effluent quality; and in the low-concentration wastewater scenario, excessive organisms consume too much dissolved oxygen or nutrients, resulting in waste of aeration energy and a surge in sludge production, which not only increases treatment costs, but also triggers chain reactions such as sludge swelling and decreased bacterial activity, affecting the long-term stable operation of the device. Summary of the Invention

[0005] In response to the above-mentioned shortcomings of the prior art, the present invention provides an environmentally friendly and efficient wastewater treatment device, which can effectively solve the problem in the prior art that when the concentration of organic matter in the wastewater fluctuates greatly, the fixed biomass easily leads to high-concentration wastewater being unable to be fully degraded and the effluent water quality does not meet the standards.

[0026] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects:

[0027] 1. The biological treatment tank is divided into an anaerobic zone and an aerobic zone by a partition plate in the biological treatment tank, thereby realizing anaerobic and aerobic biological treatment of wastewater. The water flow agitators located in the anaerobic zone and the aerobic zone stir the wastewater so that the wastewater in the two zones is fully in contact with the corresponding biological delivery mechanism. The oxygenation mechanism is used to supplement the oxygen content in the wastewater undergoing biological treatment in the aerobic zone to meet the purification process of organic matter in the wastewater by aerobic organisms in the aerobic zone. The water flow agitator can ensure that the wastewater is fully in contact with the anaerobic and aerobic organisms, accelerate the decomposition of pollutants, and improve the treatment efficiency. The oxygenation mechanism is used to increase the dissolved oxygen content in the aerobic zone, creating a suitable living environment for aerobic organisms and ensuring their activity and purification effect.

[0028] 2. The aerobic incubator and anaerobic incubator in the culture mechanism are used to replenish the corresponding aerobic or anaerobic organisms consumed by the biological delivery mechanisms located in the anaerobic and aerobic zones. The biological attachment rack in the biological delivery mechanism enables the attachment of aerobic or anaerobic organisms to prevent them from being directly mixed in the wastewater. The biological barrier component can prevent the impact of wastewater from causing aerobic or anaerobic organisms to separate from the biological attachment rack. The biological attachment rack provides a carrier for microorganisms, preventing them from being lost in the wastewater flow, thereby improving the retention rate and utilization rate of microorganisms. At the same time, the biological barrier component can further strengthen the fixation effect of aerobic or anaerobic organisms, resist the impact of wastewater flow, and ensure that the microorganisms can continuously and stably perform their degradation function.

[0029] 3. By controlling the opening and closing and the degree of opening and closing of the hollow blocks through the opening and closing components in the biological feeding machine, the corresponding hollow blocks can be opened according to the amount of biomass that needs to be purified in the wastewater, so as to achieve the contact amount between the wastewater and the aerobic or anaerobic organisms attached to the biological attachment racks in the hollow blocks, thereby achieving the corresponding number or degree of opening and closing of hollow blocks according to the amount of organic matter that needs to be anaerobically or aerobically treated in the wastewater, and realizing the on-demand supply of biological (aerobic or anaerobic) resources. When the organic matter load in the wastewater is high, the number or degree of opening of the hollow blocks can be increased to enhance the efficiency of the interaction between microorganisms and pollutants; otherwise, the contact can be reduced to avoid excessive consumption of nutrients and energy by microorganisms.

The other end of the rope 432 passes through the through hole 4331, the pulling block 4341 and is fixedly connected to the reel of the electric rope puller 436 in sequence.

[0071] The multiple communication frames 433 in the opening and closing assembly 43 are used to achieve communication between the interior of the hollow block 41 and the wastewater, while the elastic rope reel 431 uses elasticity to wind the rope 432, and the electric rope puller 436 pulls the rope 432 downward.

[0072] Reference Figures 9 to 12 A buffer assembly 435 is provided inside the guide groove 4332 of the connecting frame 433. The buffer assembly 435 includes a double-conical column 4351 fixedly connected to the inner wall of the connecting frame 433 in a linear array.

[0073] The buffer assembly 435 is used to decelerate and buffer the wastewater that enters the hollow block 41 due to the stirring of the water flow agitator 15 and then contacts the biological barrier assembly 44 and the biological attachment rack 45, so as to avoid excessive impact of the wastewater flow, which may cause the aerobic organisms or anaerobic organisms attached to the biological attachment rack 45 to break away from the attachment of the biological attachment rack 45 and the restriction of the biological barrier assembly 44, and then mix with the wastewater.

[0074] Reference Figure 6 、 Figure 13The biological barrier assembly 44 includes a fixed frame 441 fixedly connected to the inside of the hollow block 41, two barrier nets 442 and a one-way air valve 443 are fixedly connected on both sides of the fixed frame 441, and the one-way air valve 443 is located between the two barrier nets 442, and the interior of the fixed frame 441 is fixedly connected to a biological attachment rack 45.

[0075] The biological barrier assembly 44 and the fixing frame 441 are used to fix the barrier net 442 and the one-way air valve 443 inside the hollow block 41. The one-way air valve 443 is used to separate the wastewater from the biological barrier assembly 44 after the liquid completes the replenishment of organisms to the biological attachment rack 45.

[0076] The working principle of the present invention is as follows:

[0077] Step 1: First, the wastewater to be treated flows from the previous process into the aerobic zone of the biological treatment tank 1 through the water inlet pipe 12. The aerobic zone is in an aerobic environment covered by the breathable plate 19, and the anaerobic zone is closed by the sealing plate 18 to form an oxygen-free environment.

[0078] When the liquid level sensor in the aerobic zone detects that the wastewater entering the aerobic zone through the water inlet pipe 12 reaches a set height (such as 2 / 3 of the height of the biological treatment tank 1, and the specific set height can be customized by the staff in the controller), it will feedback information to the controller, thereby shutting down the previous process of transporting wastewater to the aerobic zone. At the same time, the controller sends a signal to the water flow agitator 15 and the biological detector located in the aerobic zone, causing the water flow agitator 15 (the water flow agitator 15 is a three-blade propeller type) to start rotating and stirring the aerobic zone wastewater, ensuring that the aerobic zone wastewater forms an axial circulation, thereby breaking the static state of the water body, giving the aerobic zone wastewater a little power, and promoting full contact between the wastewater in the aerobic zone and the aerobic zone biological delivery mechanism 4.

[0079] Among them, as the water flow agitator 15 starts working, the aeration fan 21 (the aeration fan 21 has an air filtering function) is also started synchronously, so that the outside air is transported to the first three-way valve 23 through the connecting pipe 22, and the air is diverted to two diversion pipes 24 through the first three-way valve 23, and then transported to the exhaust block 25 at the bottom of the aerobic zone through multiple branches of the diversion pipe 24. The exhaust block 25 evenly releases tiny bubbles to increase the oxygen content of the wastewater in the aerobic zone to meet the needs of subsequent aerobic purification of organic matter. The aerobic zone is connected to the external environment through the breathable plate 19, so that when the aeration fan 21 increases the oxygen content of the wastewater in the aerobic zone through the exhaust block 25, the pressure in the aerobic zone will not be changed.

[0080] At the same time, the biological detector starts to detect the content of organic matter that needs aerobic treatment in the aerobic zone and feeds the data back to the controller.

[0081] When the controller receives the organic matter content data fed back by the biological detector, it controls the electric rope puller 436 in the hollow block 41 of each biological delivery mechanism 4. The electric rope puller 436 opens and closes the elastic telescopic door 434 according to the content of organic matter that needs aerobic treatment in the aerobic zone.

[0082] Step 2: When the wastewater just enters the aerobic zone for biological treatment (the organic matter content is relatively high at this time): the electric rope puller 436 will rotate the reel in the opposite direction, thereby releasing the rope 432. Under the action of the rebound of the elastic telescopic door 434 and the elastic rope reel 431 (internal spring structure), the rope 432 will actively retract to the elastic rope reel 431, and the elastic telescopic door 434 will reset under the action of elastic force, thereby fully opening the connecting frame 433 (opening 100%), so that the wastewater from the aerobic zone can fully enter the hollow block 41 through the connecting frame 433, and fully contact the organisms attached to the biological attachment rack 45 in the hollow block 41 (at this time, the organisms attached to the biological attachment rack 45 are aerobic organisms).

[0083] The time for wastewater to enter the aerobic zone for biological treatment gradually increases (the organic matter content gradually decreases at this time): the electric rope puller 436 rotates the reel forward according to the organic matter content data fed back by the biological detector, and begins to gradually retract the rope 432 into the electric rope puller 436, and then pulls the rope 432 downward to pull the pull block 4341. The elastic rope reel 431 has gradually released the rope 432 under the pulling force of the electric rope puller 436, thereby driving the elastic telescopic door 434 to slide along the guide groove 4332 toward the inside of the hollow block 41, thereby gradually closing the connecting frame 433 (the opening gradually decreases), reducing the contact amount between wastewater and microorganisms, and avoiding excessive consumption of nutrients by microorganisms.

[0084] When the elastic telescopic door 434 is opened to allow wastewater to enter the connecting frame 433, the double-conical columns 4351 (with guide grooves 4352 on the surface) of the buffer assembly 435 cooperate with the double-conical columns 4351 and the connecting block 4353 to reduce the water flow velocity and reduce the impact on the subsequent biological barrier assembly 44. The adjacent double-conical columns 4351 form a labyrinthine flow channel through the connecting holes 4354 of the connecting block 4353 and the guide grooves 4352, extending the residence time of the wastewater in the hollow block 41 and ensuring the contact time between organic matter and aerobic organisms in the wastewater.

[0085] When the wastewater passes through the connecting frame 433 and the buffer assembly 435, the wastewater uses the power provided by the water flow agitator 15 to pass through the barrier net 442 and enter the area of ​​the biological attachment rack 45. Aerobic organisms that act on the wastewater in the aerobic zone are attached to the biological attachment rack 45, and the barrier net 442 limits the range of the wastewater therein, so that the biological attachment rack 45 can be more fully in contact with the wastewater, thereby completing the process of aerobic organisms in the aerobic zone purifying organic matter in the wastewater that requires aerobic treatment.

[0086] When the biological detector in the aerobic zone detects that the content of organic matter in the wastewater requiring aerobic treatment has reached the discharge value, the elastic retractable doors 434 in the opening and closing assembly 43 will all be closed in the communication frame 433, and the oxygenation mechanism 2 will also stop working synchronously. At this time, the controller will start the water pump 17, thereby sucking the wastewater in the aerobic zone through the porous valve 16 in the aerobic zone and then discharging the wastewater into the anaerobic zone through the porous valve 16 in the anaerobic zone.

[0087] It should be noted that when the wastewater is transferred from the aerobic zone to the anaerobic zone, the magnetic drain valve 46 in the hollow block 41 will lose its closing suction due to power failure and then open, thereby draining the wastewater in the hollow block 41 so that there is no wastewater in the hollow block 41.

[0088] When the liquid level sensor in the aerobic zone detects that there is no wastewater in the aerobic zone, the magnetic drain valve 46 will regain its magnetism and close.

[0089] Special note: At this time, the aerobic incubator 31 (the aerobic incubator 31 has a culture medium for cultivating and breeding aerobic organisms, and maintains the activity and reproduction of aerobic organisms through temperature control and nutrient supply (such as carbon source, nitrogen source, and phosphorus source), and the mature microorganisms and the nutrient solution form a mixed liquid, which is stored in the incubator) transports the mixed liquid to the second three-way valve 34 through the output pipe 33, and enters the interconnecting pipe 35 after diversion. The mixed liquid in the interconnecting pipe 35 is controlled by the solenoid valve 36 and flows into the connecting cover 37 (connected to the open side of the hollow block 41), and finally enters the interior of the hollow block 41. Note that the elastic telescopic door 434 of the opening and closing component 43 is in a closed state at this time to prevent the mixed liquid from leaking out and ensure that the replenishment process is concentrated in the hollow block 41.

[0090] When the mixed liquid enters, the pressure relief pipe 42 and the pressure relief valve 421 are used to release excess air pressure in the hollow block 41 to prevent excessive internal pressure from affecting the inflow of the mixed liquid. The mixed liquid passes through the barrier net 442 of the biological barrier component 44 and is submerged on the surface of the biological attachment rack 45. When the controller detects that the replenishment time has reached a preset value (such as 10 minutes, the specific actual time is customized by the staff in the controller according to actual conditions), it indicates that the surface of the biological attachment rack 45 has been replenished with aerobic organisms, and the solenoid valve 36 is then closed. At this time, the aerobic incubator 31 begins to absorb the mixed liquid entering the hollow block 41 through the return pipe 47. From then on, the pressure relief pipe 42 and the pressure relief valve 421 are used to maintain the air pressure balance in the hollow block 41 to avoid the occurrence of a negative pressure condition in the hollow block 41 due to the continuous absorption of the mixed liquid in the hollow block 41, so that the nutrient solution and the remaining aerobic organisms can return to the aerobic incubator 31, realizing the cyclic reproduction of the nutrient solution and the aerobic organisms.

[0091] Step 3: The wastewater entering the anaerobic zone will repeat the working process of the first and second steps. The only difference is that the aerobic organisms in the first and second steps become anaerobic organisms, thereby achieving the purification of organic matter that requires anaerobic treatment in the anaerobic zone, and the purified wastewater will be discharged from the outlet pipe 13 to the next process.

[0092] After the anaerobic zone completes the purification of organic matter, the anaerobic incubator 32 (the anaerobic incubator 32 is basically the same as the aerobic incubator 31, the only difference being that the anaerobic incubator 32 is used to cultivate and reproduce anaerobic organisms) repeats the process of the aerobic incubator 31 replenishing aerobic organisms to the biological attachment racks 45 in the aerobic zone in the second step, thereby achieving the purpose of replenishing anaerobic organisms to the biological attachment racks 45 in the anaerobic zone.
