Name: Underground sewage treatment equipment

details

　　The underground sewage treatment equipment is mainly based on the A/O process. The main body of the equipment is buried underground, reducing the area of saving, the economy is all set underground, the operation is economical, the impact concentration resistance is strong, the treatment efficiency is high, and the management and maintenance are convenient.

Buried sewage treatment equipment features

　　1. Buried below the surface of the earth, the surface above the equipment can be used as a greening or other land. It does not need to build houses, heating and heat preservation.

       2. The secondary biological contact oxidation treatment process adopts push-flow biological contact oxidation, and its treatment effect is better than the complete mixed or two-stage series fully mixed biological contact oxidation tank. Compared with the activated sludge tank, it has small volume, strong adaptability to water quality, good impact load resistance, stable effluent quality and no sludge expansion. The new elastic three-dimensional filler is used in the pool, the specific surface area is large, the microorganisms are easy to hang the membrane, and the membrane is removed. Under the same organic matter load condition, the organic matter removal rate is high, and the solubility of oxygen in the air in water can be improved.

       3, biochemical pool using biological contact oxidation method, the volume load of the filler is relatively low, the microbe is in its own oxidation step, the amount of mud production is small, only need three months (90 days) or more to discharge the mud (with a sewage pump or Dehydrated into a mud cake for export).

       4. The deodorization method of the buried domestic sewage treatment equipment is not only the conventional high-altitude exhaust, but also the soil deodorization measures.

       5, the entire equipment processing system is equipped with a fully automatic electrical control system and equipment fault alarm system, the operation is safe and reliable, usually do not need to be managed by special personnel, only need timely maintenance and maintenance of the equipment.

Buried sewage treatment equipment suitable for conditions

　　The amount of water is small, the concentration of pollutants is small, the composition is not complicated, the site is limited, and the surrounding environment beautification factors need to be considered. In general, it is recommended to use a buried sewage treatment equipment system for treatment in the above cases.

Buried sewage treatment equipment application range

　　1. Hotels, restaurants, nursing homes, hospitals;

       2. Residential quarters, villages, market towns;

       3. Stations, airports, harbor terminals, ships;

       4. Factory, mine, troops, tourist spots, scenic spots;

       5. Various industrial organic wastewater similar to domestic sewage
