New rural integrated sewage treatment project renovation equipment——Product Application

The integrated domestic sewage treatment equipment adopts the world's most advanced biological treatment process, integrating the removal of BOD, COD, and NH-N, and is currently a convenient sewage treatment equipment.

II Product Features

(1) It can be buried underground and the surface can be used as green or square land, so the equipment does not occupy the surface area, does not require building, and does not require heating and insulation.

(2) Composed of two sets of equipment made of steel structure, using domestic anti-corrosion coatings for corrosion prevention. It is resistant to acid, alkali, salt, gasoline, kerosene, aging, abrasion, and rust. After applying the coating, the anti-corrosion life of the equipment can generally reach more than 15 years.

(3) The AO biological treatment process adopts a push flow biological contact oxidation tank, which has a better treatment effect than a mixed or two-stage series mixed biological contact oxidation tank. And it has a smaller volume than activated sludge tanks, strong applicability to water quality, good impact resistance, stable effluent quality, and will not cause sludge expansion. At the same time, a new type of elastic three-dimensional material is used in the biological contact oxidation tank, which has practical applicationsIt has a large actual specific surface area, microbial biofilm formation, and easy membrane removal. Under the same organic load conditions, it has a higher removal rate of organic matter than other fillers. Can increase the solubility of nutrients in water in the air.Large specific surface area, microbial biofilm formation, easy membrane detachment, and higher removal rate of organic matter than other fillers under the same organic load conditions. Can increase the solubility of nutrients in water in the air.

(4) Due to the use of a biological contact oxidation tank in the AO biological treatment process, the volume load of the packing is relatively low, and the microorganisms are in the self oxidation stage, resulting in less sludge production. In addition, the moisture content of the sludge produced by the biological contact oxidation tank is much lower than that of the sludge produced by the activated sludge tank. Therefore, the amount of sludge generated by the WSZ series sewage treatment equipment is relatively small, and generally only needs to be discharged once every 90 days.

(5) In addition to using conventional measures such as vibration isolation pads and silencers, new sound-absorbing materials have also been installed on the inner wall of the blower room, reducing the noise level during equipment operation to below 50 decibels and minimizing its impact on the surrounding environment.

(6) Equipped with soil deodorization measures, it utilizes the upper space of the reinforced concrete structure pool to set up improved soil and air distribution pipes. When odorous components dissolve in the water contained in the soil through the soil layer, they are then transferred into the soil due to surface adsorption and chemical reactions, and decomposed by microorganisms to achieve deodorization.

(7) The fully automatic electrical control system and equipment damage alarm system have good reliability, so there is generally no need for dedicated personnel to manage them, only monthly or quarterly maintenance and upkeep are required.

With the development of animal husbandry in our country, industrial competition is becoming increasingly fierce. The scale and intensive development of animal husbandry has become an inevitable trend. Large scale breeding has high feeding technology, unified management, reduced costs, and improved economic benefits. However, the environmental pollution caused by the discharge of a large amount of concentrated feces and sewage is becoming more and more serious. The manure, urine, excrement, and wastewater from the aquaculture industry contain a large amount of organic matter, nitrogen, phosphorus, suspended solids, and pathogenic bacteria, which produce a foul odor. Direct discharge into rivers or surface water will seriously pollute water sources and soil environments, destroy the original functions of water bodies, endanger human health and agricultural and fishery production, such as eutrophication, and cause fatal damage to water quality.
