WSZ-AO Sewage treatment equipment

With the deepening of China's opening up, China's booming tourism and real estate, luxury hotels and villas where they stand, grade hotels and villas and often far from urban sewage treatment plants, to centralized sewage treatment inconvenience, to protect the environment for future generations by Tongji University successfully developed WSZ-AO series Sewage treatment equipment. The device uses advanced biological treatment processes in the world, set to remove BOD5, COD, NH3-N in one, is the most efficient Sewage treatment equipment. It is widely used in sewage treatment luxury hotels, villas and residential areas, replacing the removal rate is very low, can not meet the state discharge standards septic post-processing. After field application shows, WSZ-AO series Sewage treatment equipment is a treatment effect is very good and easy to manage device.

working principle

WSZ-AO series Sewage treatment equipment to remove organic pollutants and ammonia nitrogen depends on the device AO biological treatment process. Which works at the A level, because the sewage organic matter concentration is high, microorganisms in a hypoxic state, this time for the microbes and micro-organisms, so the A-level pool only has a certain organics removal function, reduce the subsequent aerobic pool organic load, decreased again, but there is still a certain amount of organic matter and high NH3-N exists. In order to further oxidation and decomposition of organic matter, while in the carbonation to complete nitrification can proceed smoothly case, set a lower organic loading aerobic biological contact oxidation pond at O level. O level in the main pool for aerobic microorganisms and bacteria from oxygen (denitrifying bacteria). Which aerobic microorganisms to decompose organic matter into CO2 and H2O; autotrophic bacteria (denitrifying bacteria) or the use of inorganic carbon produced by decomposition of organic matter in the air of CO2 as a nutrient source, sewage NH3-N is converted to NO-2-N , NO-3-N, O-level pool of water back to the pool a level, a-level pool to provide electronic acceptor through denitrification eventually eliminate nitrogen pollution.

main feature

①WSZ-AO series Sewage treatment equipment can be buried below the surface, the surface can be used as green or square land, so that the device is not an area of surface area without building houses, but without the need for heating insulation.

②WSZ- AO Series Sewage treatment equipment from Grade pond composed of a reinforced concrete structure, great depth, another level for the steel, shallow depth, steel pool first domestic interpenetrating network anti-corrosion coating be preserved. Word is a network rubber and plastics network formed interpenetrating polymer networks that can acid and alkali, salt, gasoline, kerosene, aging resistance, abrasion, rust can rust. After brushing the general equipment coatings, corrosion life of up to 12 years.

③WSZ-AO series Sewage treatment equipment in AO biological treatment process using plug-flow biological contact oxidation pond, its treatment is better than full hybrid or two, three series completely mixed biological contact oxidation pond. It is small and less than the volume of the sludge pond, water quality adaptability, good impact resistance, water quality and stability, no sludge expansion. While in the biological contact oxidation tank using a new three-dimensional elastic Packing, which has the actual large surface area, microbial biofilm formation, stripping easy, under the same organic load conditions than other Packing for organics removal, improve air solubility of oxygen in water.

④ Since AO biological treatment process using biological contact oxidation pond, the volume is relatively low load its Packing, microbial oxidation stage is in itself, and therefore less sludge production. In addition, the biological contact oxidation pond sludge moisture content produce far much lower than the activated sludge tank sludge produced by the moisture content. Therefore, the less the amount of sewage sludge by TWZ series Sewage treatment equipment produced after generally only about 90 days a row of mud.

⑤WSZ-AO series Sewage treatment equipment in addition to the regular use of blower silencers measures (such as isolation pads, silencers, etc.), also in the inner wall of the blower housing set new sound-absorbing material, so that the device is running noise below 50 decibels, mitigation the impact on the surrounding environment
