Key word：

First, product features

1, buried below the surface, the surface can be used as a device or other green land, without heating, thermal insulation and building.

2. The biological contact oxidation process of the two and the third stage adopts the biological contact oxidation with push flow, and the treatment effect is better than that of the complete mixed type or the two stage series complete mixed biological contact oxidation tank. Compared with the activated sludge tank, the utility model has the advantages of small volume, strong adaptability to water quality, good impact load resistance, stable effluent quality and no sludge bulking. The utility model adopts a novel elastic stereo filler with a large specific surface area, and the microorganism is easy to film and film off, and the organic matter removal rate is high under the condition of the same organic load, which can improve the solubility of oxygen in the air.

3, biochemical pool by biological contact oxidation, the filler volume load is relatively low in microbial self oxidation stage, less sludge production, only three months (90 days) more than a row of mud (with fecal suction or dehydrated sludge cake Sinotrans).

4, the deodorization buried sewage treatment equipment in addition to the conventional air exhaust, the other with soil deodorization measures.

5, the entire equipment processing system is equipped with automatic electrical control system and equipment fault alarm system, safe and reliable operation, usually do not need special management, just in time to the equipment maintenance and maintenance.

Method of use two, buried sewage treatment device for several

• ability to handle complex wastewater from domestic systems and similar organic wastewater;

The use of glass fiber reinforced plastic, stainless steel structure, corrosion resistance, anti-aging and other excellent characteristics, the service life of more than 50 years;

The complete set of equipment construction is simple, easy to operate, all mechanical equipment are automatic control, all devices can be set on the surface;

Scope three, buried sewage treatment device

1, hotels, restaurants, nursing homes, hospitals;

2, residential areas, villages, towns;

3, stations, airports, seaports, ships;

4, factories, mines, troops, tourist attractions, scenic spots;

5, similar to domestic sewage and industrial organic wastewater.
