The pneumatic collector 15 is used to increase the stability coefficient of the removed sludge and the redox potential of the treated water.

[0033] In this embodiment, by combining the flotation water purification technology with the microbial decomposition purification method, the air used in the flotation bioreactor body 2 is naturally cooled, the redox potential gradient value of the water is increased, and the flotation effect of the harmful sludge with environmental hazards in the flotation bioreactor body 2 is strengthened, and the stability of pollutant removal is ensured. The solution containing biodegradable microorganisms sprayed by the coordinated biodegradation agent quantitative device 5 and the surface sprayer 7 is combined with the harmful sludge floated up, so that a high-quality new result can be obtained. Therefore, through the flotation treatment, the pollutants with environmental hazards are separated, and combined with the destruction of microorganisms, the organic impurities in the sludge with environmental hazards can be converted into nutrients required by microorganisms, and further converted into fermentation compost biological fertilizers. Biofertilizers can be used to grow plants. Through the flotation process, pollutants are finally purified and converted into biofertilizers that are beneficial to the environment. By flotating harmful sludge and combining it with a microbial degradation solution, water purification problems in hot and dry climates and desert areas, as well as open source water supply and wastewater and waste treatment problems in human settlements can be solved, making wastewater treatment in wastewater treatment plants not only a waste-free environmentally friendly technology, but also a profitable environmentally friendly industry.

[0034] Specifically, refer to Figure 1 A solution regulator 6 and a regulator 8 are respectively provided on both sides of the biodegradation agent quantitative device 5 .

[0035] In this embodiment, when the sludge particles in the pollutants are floated to the upper part of the flotation bioreactor body 2, a solution containing biodegradable microorganisms is added to the floating flotation sludge. The solution is supplied by the biodegradation agent quantitative device 5 and the solution regulator 6 and transferred to the surface sprayer 7 in conjunction with the connection of the pipeline, and is sprayed from the surface sprayer 7 on the surface and volume of the flotation sludge to complete the fusion. The biodegradable microbial solution can decompose the organic and synthetic components in the pollutants through the synthesis of microorganisms, and the result of the biological reaction is the biodegradation and disinfection of the harmful sludge produced in the death environment of protozoa, opportunistic parasites and pathogenic microorganisms. In addition, during the decomposition, a fermentation process also occurs, which increases the biological value of the polluting elements, that is, the harmful flotation sludge can be converted into organic fertilizer through biochemical, structural and microbiological transformations, and the organic fertilizer can be used for plant cultivation.

[0036] Specifically, refer to Figure 1A water collecting pool 9 is provided on one side of the flotation bioreactor body 2 and the flotation bioreactor body 2 is connected to the flotation bioreactor body 2 through a pipeline, and a purified water outlet pipeline 10 is provided on the other side of the water collecting pool 9 and is connected to the water collecting pool 9.

[0037] In this embodiment, after the harmful flotation sludge is decomposed into organic fertilizer, next, the water from the flotation bioreactor body 2 enters the water collection tank 9, in which the mineralized organic matter and insoluble particles that have not been separated from the flotation sludge are deposited. The treated water is discharged through the purified water outlet pipe 10, and the flotation sludge with increased environmental harm is discharged from the sedimentation tank through the sludge discharge pipe 11 and enters the sludge and flotation sludge mixed bioreactor body 12.

[0038] Specifically, refer to Figure 1 A sludge discharge pipe 11 is connected to the lower end of the water collecting tank 9, and the sludge discharge pipe 11 extends into a main body 12 of a sludge and flotation sludge mixed bioreactor.

[0039] In this embodiment, after the flotation sludge is combined with the biodegradable microbial solution and decomposed, the water from the flotation bioreactor body 2 will enter the water collection tank 9, in which the mineralized organic matter and insoluble particles that have not been separated from the flotation sludge are deposited. The treated water is discharged through the purified water outlet pipe 10, and the harmful flotation sludge with environmental hazards is discharged from the sedimentation tank through the sludge discharge pipe 11 and enters the sludge and flotation sludge mixed bioreactor body 12. The regulator 8 provides a solution enzyme for biodegradation. At the same time, with its help, the flotation sludge with environmental hazards undergoes a complete fermentation and conversion cycle, for example, it is converted into an effective biofertilizer for plants.

[0040] Specifically, refer to Figure 1 A surface sprayer 7 is provided above the flotation bioreactor body 2, and the surface sprayer 7 is connected to the biodegradation agent quantitative device 5 through a pipeline.

[0041] In this embodiment, when the harmful sludge is floated from the flotation bioreactor body 2 to the upper part of the flotation bioreactor body 2, the solution containing biodegradable microorganisms can be added to the floating flotation sludge, and the solution is supplied by the biodegradation agent quantitative device 5 and the solution regulator 6 and transferred to the surface sprayer 7 in conjunction with the connection of the pipeline, and is sprayed on the surface and volume of the flotation sludge through the surface sprayer 7 to complete the fusion. At the same time, due to the use of biodegradable enzyme solution and the use of cooling air from an additional underground air inlet, the underground air inlet is placed in the pit 16 and / or ditch 1 below the ground. 7, and the air inlet is interconnected with the pneumatic collector 15, which can not only effectively purify water and remove various pollutants that are harmful to the environment, including synthetic dissolved substances and organic compounds, but also the wastewater treatment facility can get rid of the unpleasant odor associated with the decay of waste piles. At the same time, through the biological process of decomposition and fermentation, harmful insects and pathogens in the water body are decomposed and fermented to become a biological organic fertilizer in the form of compost. Importantly, the decomposition process itself is fast, does not require excessive energy and chemical consumption, and ensures an increase in the stability coefficient of sludge removal and the redox potential gradient value of the treated water.

[0042] Specifically, refer to Figure 1 The pneumatic collector 15 is connected to the gas saturation system 3 through an air pipe 18.

[0043] In this embodiment, the redox potential gradient value of the treatment water in the flotation bioreactor body 2 is increased by the conduction of cooling air from the underground pneumatic collector 15, in conjunction with the pneumatic connection between the air duct 18 and the gas saturation system 3, thereby facilitating the reduction potential to bind and transfer to the suspended dissolved synthetic matter and a large amount of organic and mineral pollutants, and allowing the sludge particles in the pollutants to be floated to the upper part of the flotation bioreactor body 2 more quickly.

[0044] The collaborative water treatment device of the utility model:

[0045] Step 1: The water for purification is supplied to the flotation bioreactor body 2 through the water supply pipe 1. With the help of the gas saturation system 3, the gas in the flotation bioreactor body 2 is in a saturated state, and then the process of aeration and flotation particles is actively carried out. Through the expansion of the gas, the sludge that forms environmental hazards is floated out and floats above the water body in the flotation bioreactor body 2;

[0046] Step 2: Through the cooling air conduction from the pneumatic collector 15 buried underground, in conjunction with the pneumatic connection between the air pipe 18 and the gas saturation system 3, the redox potential gradient value of the treatment water in the flotation bioreactor body 2 is increased, which is helpful for combining and transferring to the dissolved synthetic matter and a large amount of organic and mineral pollutants in the suspended state, and makes the sludge particles in the pollutants float to the upper part of the flotation bioreactor body 2 more quickly. At this time, the solution containing biodegradable microorganisms is added to the floating flotation sludge. The solution is supplied between the biodegradation agent quantitative device 5 and the solution regulator 6 and transferred to the surface sprayer 7 in conjunction with the connection of the pipeline, and is sprayed from the surface sprayer 7 on the surface and volume of the flotation sludge to complete the fusion;

[0047] Step 3: The composition of the biodegrading microorganisms is selected in such a way that in the presence of air, especially cooling air, they are able to decompose the organic and synthetic components of the pollutants through microbial synthesis. The result of the biological reaction is the biodegradation and disinfection of the sludge that is more harmful in the dead environment of protozoa, opportunistic parasites and pathogenic microorganisms. In addition, a fermentation process occurs, which increases the biological value of the polluting elements and turns the harmful flotation sludge into organic fertilizer through biochemical, structural and microbiological transformations. Next, the water from the flotation bioreactor body 2 enters the collection tank 9, in which the mineralized organic matter and insoluble particles that have not been separated from the flotation sludge are deposited. The treated water is discharged through the purified water outlet pipe 10, and the environmentally harmful flotation sludge is discharged from the sedimentation tank through the sludge discharge pipe 11. The sludge and flotation sludge mixed bioreactor body 12 is fed into the sludge and flotation sludge mixed bioreactor body 12, and the regulator 8 provides a solution enzyme for biodegradation. At the same time, with its help, the flotation sludge with environmental hazards undergoes a complete fermentation and conversion cycle, for example, it is converted into an effective biofertilizer for plants, because the provided biological culture is selected in such a way that all biodegradable things are its nutrients. In order to create the best conditions for this process, a water level control system is also provided above the flotation sludge. The system utilizes the drive of the circulation device 14 and regularly pumps excess water to the head of the sludge and flotation sludge mixed bioreactor body 12 through the decanting pipe 13, thereby creating the necessary living conditions for anaerobic biodegradable microorganisms, and finally realizes the decomposition and fermentation of the flotation sludge with environmental hazards into biofertilizer for plants through the water treatment device.
