1.Characteristic
(1). WSZ type complete device for sewage treatment is buried underground and greening can be carried out to the surface above the equipment. It is not necessary to construct house, maintain heat and warmth retention. The anti-corrosion manufacturing can be carried out to the equipment with less than 5t/h water quantity by adopting the fiber glass or A3 steel board.
(2). The secondary biological contact oxidation treatment process adopts the blast aeration. The activated sludge owns small volume and excellent adaptability to water quality. The influent water quality is stable without producing sludge swell.
(3). The reaction tank utilizes the biological touch oxidation method and sludge discharge (the night cart is used for suction or dehydration for sludge cake for out transportation) needs carrying out for only three months (90 days).
(4). The whole treatment equipment does not need establishing professionals for management under general circumstance, and only maintenance is entailed for the equipment at the proper time.
(5). It owns quite strong adaptability to the change of the water quality with a small amount.
(6). The compressed container, air compressor, circulation pump and other equipment become unnecessary, therefore, the investment cost has been reduced dramatically.
(7). The power needed is low with fewer maintenance and artificial operation. ZWF is a process of oxygen exhaust and the odor problem produced by sludge has been resolved.

2. Usage
(1) The device can be used in treating the domestic sewage and related organic sewage;
(2) The device features easy operation, automatic control, it can be buried under the ground;
(3) Convenient maintenance, the working life can be more than 30 years.
3. Application
