Underground Sewage Treatment Plant

1. Product Overview

The equipment adopts international biological treatment technology, on the basis of summarizing the operation experience of domestic sewage treatment plants at home and abroad, combined with our company's own scientific research achievements and engineering practice, we have designed a complete set of organic wastewater treatment devices that can be set up in the ground, which integrates the removal of BOD5, COD and NH3-N, and has the advantages of stable and reliable technical performance, good treatment effect, low investment, automatic operation, convenient maintenance and operation, no area occupied by surface area, no need to build a house, no need for heating and insulation, etc. Flowers and grasses can be planted on the ground without affecting the surrounding environment.

The equipment is suitable for the treatment and reuse of domestic sewage such as residential quarters, villages, villages and towns, office buildings, shopping malls, hotels, restaurants, nursing homes, institutions, schools, troops, hospitals, highways, railways, factories, mines, tourist attractions and similar slaughtering, aquatic product processing, food and other small and medium-sized industrial organic wastewater. The water quality of the sewage treated by the equipment meets the discharge standard. Our company can be equipped with reclaimed water reuse equipment according to user requirements.

Second, product features

1. Buried below the surface, the surface above the equipment can be used as greening or other land, and there is no need to build a house, heating and insulation.

2. The secondary biological contact oxidation treatment process adopts push-flow biological contact oxidation, and its treatment effect is better than that of the fully mixed or two-stage series fully mixed biological contact oxidation pool. It is smaller than the activated sludge tank, has strong adaptability to water quality, good impact load resistance, stable effluent water quality, and will not produce sludge expansion. The pool adopts a new type of elastic three-dimensional filler, which has a large specific surface area, microorganisms are easy to hang the film, and the film is removed, and the removal rate of organic matter is high under the same organic matter loading conditions, which can improve the solubility of oxygen in the air in water.

3. The biochemical tank adopts biological contact oxidation method, the volume load of its filler is relatively low, the microorganisms are in the self-oxidation stage, and the sludge production is small, and it only takes more than three months (90 days) to discharge the mud once (sucked or dehydrated into mud cake by fecal truck and transported).

4. In addition to the conventional high-altitude exhaust, the deodorization method of the buried domestic sewage treatment equipment is equipped with soil deodorization measures.

5. The whole equipment processing system is equipped with a fully automatic electrical control system and equipment fault alarm system, which is safe and reliable in operation, and generally does not need special personnel to manage it at ordinary times, but only needs to maintain and maintain the equipment in a timely manner.

3. Scope of application

1. Hotels, restaurants, nursing homes, hospitals;

2. Residential quarters, villages, and market towns;

3. Stations, airports, seaports, terminals, and ships;

4. Factories, mines, troops, tourist spots, scenic spots;

5. All kinds of industrial organic wastewater similar to domestic sewage.
