Integrated sewage treatment equipment in residential area
1、 Overview of integrated sewage treatment equipment
The integrated sewage treatment equipment adopts the international advanced biological treatment method, and integrates the removal of COD, BOD and NH3-N. the effluent quality can reach the first-class sewage discharge standard. It has the advantages of stable and reliable technical performance, good treatment effect, less investment, less land occupation and convenient maintenance. According to customer requirements, materials can be divided into carbon steel, FRP, stainless steel, carbon steel corrosion and other materials. The product can be buried underground or on the ground.
2、 Product features
1. The equipment can be fully buried, semi buried, or placed above the surface, and can be arranged in different forms and designed according to the needs of the terrain.
2. It is buried under the surface, and the surface above the equipment can be used as green or other land, without building, heating and thermal insulation.
3. The two-stage biological contact oxidation process adopts plug flow biological contact oxidation, and its treatment effect is better than that of complete mixed or two-stage series complete mixed biological contact oxidation tank. Compared with activated sludge tank, it has small volume, strong adaptability to water quality, good shock load resistance, stable effluent quality and no sludge bulking. The new type of combined packing is used in the tank, with large specific surface area and easy biofilm formation and removal by microorganisms. Under the same organic loading condition, the removal rate of organic matter is high, and the solubility of oxygen in air in water can be improved.
4. The biological contact oxidation method is adopted in the biochemical tank. The volume load of the filler is relatively low, the microorganism is in its own oxidation stage, and the sludge production is small. It only takes more than three months (90 days) to discharge the sludge (pumped or dehydrated by the manure truck to form sludge cake for outward transportation).
5. The whole equipment processing system is equipped with full-automatic electrical control system and equipment fault alarm system, which is safe and reliable in operation. Usually, there is no need for special person to manage, but only need to timely maintain the equipment.
6. All pipes of the equipment are PVC or stainless steel pipes, and the connection between pipes is bonded with PVC adhesive or welded with stainless steel.
3、 Several application methods of buried domestic sewage treatment device
Be able to treat comprehensive wastewater of domestic system and similar organic wastewater;
It adopts glass fiber reinforced plastic, carbon steel and stainless steel structure, and has excellent corrosion resistance and aging resistance. Its service life is longer than 50 years.
The construction of the whole set of devices is simple and easy to operate. All mechanical equipment are automatically controlled, and all devices can be set below the surface;
4、 Application scope of underground integrated sewage treatment equipment
1. Hotels, restaurants, sanatoriums, hospitals;
2. Residential quarters, villages and towns;
3. Stations, airports, harbors, docks, ships;
4. Factories, mines, troops, tourist spots and scenic spots;
5. All kinds of industrial organic wastewater similar to domestic sewage.
