1) Underground Industrial Wastewater Treatment Equipment (WSZ) can be embeded below the surface, therefore there is no floor space and no need for plant construction, neither heating nor heat preservation. The surface can be afforested.
2) WSZ device consists of steel structure, adopts new anti-corrosion material. And its anti-corrosion can reach 12 years.
3) It uses plug flow biological contact oxidation pond, the effect is better. It is smaller than active sludge pool. It has strong applicability to the water, good impact resistance performance, stable discharging water quality, but no sludge expansion. In addition, the new elastomeric stereoscopic materials applying to the oxidation pond bring a higher removing rate, and also can improve the water solubility of oxygen.
4) Because of the low volume load of fillings in AO bio-treatment technology of and microbes in the stage of oxygen, this equipment would produce less mud. Generally, around 90 days need only one sludge removal.
5) In addition to using conventional silencer to air blower, it sets new acoustical material inwall. When it is operating, noise would be under 50 decibel that reduce the influence to surrounding environment.
6) Except for the conventional air exhaust, the device is equipped with soil deodorization measure. Uitimately, stench element is decomposed by the microorganism for deodorization.
7) It is equipped with automatic electric control system and equipment damage alarm system. The device has good reliability, therefore, there is no need for special management, just needs regular maintenance.
8) On the condition of making sure the treating effect, if customers have special requirement including treating power and specification etc., we can design and manufacture specially.
