One end of the third water pipe 21 extends into the third treatment tank 19 , and the other end of the third water pipe 21 extends into the fourth treatment tank 22 .

[0038] The honeycomb brick 16 is fixedly connected to the inner wall of the second treatment tank 15. There are multiple honeycomb bricks 16. The honeycomb bricks 16 are stacked and arranged in a honeycomb structure in the second treatment tank 15. The honeycomb brick 16 is made of nano-bioenzyme sand-based microbead water purification material and has a water permeability and water filtration function. The sand-based microbead multi-media filter material 20 is filled in the third treatment tank 19. The anti-seepage active composite plate 17 is laid in the bottom wall of the treatment tank 11. The anti-seepage active composite plate 17 is made of sand-based microbead breathable anti-seepage active composite material. The anti-seepage active composite plate 17 has the characteristics of air permeability and no leakage. The anti-seepage active composite plate 17 is laid on the bottom walls of the second treatment tank 15, the third treatment tank 19 and the third water pipe 21 respectively.

[0039] A cement cover plate 24 is laid on the top wall of the treatment tank 11. A symmetrical first detection hole is provided on the cement cover plate 24 above the top wall of the second treatment tank 15, and a first baffle plate 27 is fixedly connected to the top wall of the cement cover plate 24 around the detection hole, and a first cover plate 28 is laid on the first baffle plate 27. A seepage pipe 25 is inserted into the sand-based micro-bead multi-media filter material 20, and the seepage pipe 25 is made of the same material as the sand-based micro-bead multi-media filter material 20, and the upper end of the seepage pipe 25 passes through the cement cover plate 24 and extends above the cement cover plate 24, and a second cover plate 26 is laid on the upper end of the seepage pipe 25.

[0040] Working or installation process:

[0041] The treatment pool 11 is made of cement and is divided into four treatment tanks, namely, a first treatment tank 12, a second treatment tank 15, a third treatment tank 19, and a third water pipe 21, by cement partitions. The anti-seepage active composite plate 17 is laid on the bottom of the anti-seepage active composite plate 17, the third treatment tank 19, and the third water pipe 21.

[0042] The sewage is introduced into the first treatment tank 12 through the water inlet pipe 13, and then enters the second treatment tank 15 through the first water pipe 14. The honeycomb bricks 16 perform preliminary filtration on the sewage to efficiently remove the colloid and suspended matter in the sewage.

[0043] The sewage is filtered through multiple honeycomb bricks 16 and introduced into the third treatment tank 19 from the second water pipe 18. Since the sand-based micro-bead multi-media filter material 20 has physical and chemical filtering functions, the sand-based micro-bead multi-media filter material 20 in the third treatment tank 19 decolorizes, deodorizes and removes the sewage, and adsorbs heavy metals and other pollutants in the sewage onto the surface of the sand-based micro-bead multi-media filter material 20; through the honeycomb bricks 16 made of the sand-based micro-bead multi-media filter material 20, the particles in the filtered water body provide a bed for microorganisms, which is conducive to the growth and reproduction of microorganisms. Filtration performance: The silica sand wellbore is full of micropores, which filters the sewage layer by layer like a membrane, with a removal rate of more than 95%, and efficiently removes colloids or suspended matter in the water; biological purification: the biological film is attached to the well wall to degrade organic pollutants in the sewage; intergranular effect: the pores on the well wall divide the sewage into small particles, so that it is fully in contact with the biological film, and the biological purification is more efficient.

[0044] After being filtered by the sand-based micro-bead multi-media filter material 20, the sewage is introduced into the fourth treatment tank 22 through the third water pipe 21. Since the bottoms of the second treatment tank 15, the third treatment tank 19 and the third water pipe 21 are all paved with an anti-seepage active composite board 17, the anti-seepage active composite board 17 has the characteristics of being breathable and leakproof. The micro-power generated by the temperature difference between the upper and lower water surfaces is used to promote the microcirculation of the water body, achieve the self-oxygen enrichment function, construct oxygen-enriched, anoxic, and anaerobic environmental micro-units, and promote the reproduction of aerobic, anaerobic, facultative anoxic and other bacterial communities; through the growth of microorganisms stored in the water body, the microorganisms in the water body further purify the water body:

[0045] Degradation of organic pollutants: Aerobic microorganisms play a major role in the removal of organic pollutants, converting organic carbon in water into carbon dioxide and microorganisms’ own components;

[0046] Nitrogen removal: Microbial denitrification is the process of converting organic nitrogen and NH4+-N into N2 and NXO gas under the action of microorganisms, including ammoniation, nitrification, and denitrification. Microorganisms are the main way to remove nitrogen in the system;

[0047] Removal of phosphorus: Under anaerobic conditions, the growth of polyphosphate bacteria is inhibited, and they release the polyphosphate bacteria in their cells for their own growth. After entering the aerobic environment, the activity is fully restored. While making full use of the matrix, a large amount of dissolved orthophosphate is extracted from the wastewater, thus completing the process of polyphosphate. The purpose of phosphorus removal can be achieved by removing these microorganisms that absorb a large amount of phosphorus from the wastewater. Organic phosphorus in sewage can be decomposed into inorganic phosphorus under the action of microorganisms. Inorganic phosphorus is an essential nutrient element for plant growth and can be absorbed and utilized by plants.

[0048] Through the purification of water bodies by the above-mentioned microorganisms, the sewage can be better purified and filtered. Through the above-mentioned integrated work of collecting, filtering, purifying and preserving sewage, there is basically no need to maintain the equipment in the later stage, and one-time investment will benefit for life. The water quality of the system outlet reaches the surface water standard of Class II-IV.

[0049] When it is desired to sample and test the water quality at different locations, the second cover plate 26 and the first cover plate 28 at different locations can be opened to sample and test the water quality at different locations.
