In order to meet the needs of the construction of the new socialist countryside, improve the rural water environment, change the status of rural domestic sewage discharge, improve the living environment and health level of farmers, and promote rural sewage treatment, the design process for rural domestic sewage The processing was studied and summarized.
Advantages of buried sewage treatment equipment:
1. Buried below the surface, the surface above the equipment can be used as greening or other land, without building houses, heating and thermal insulation.
2. The two-stage biological contact oxidation process adopts push flow biological contact oxidation, and its treatment effect is better than the fully 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 bulking. New elastic three-dimensional filler is used in the tank, which has large specific surface area and is easy for microorganisms to hang and remove film. Under the same organic load, it has high removal rate of organic matter and can improve the solubility of oxygen in air in water.
3. Biological contact oxidation method is adopted for the biochemical tank. The volume load of its filler is relatively low, the microorganism is in its own oxidation stage, and the sludge production is small. It only needs to discharge the sludge once more than three months (90 days) (suck or dehydrate it into mud cake by septic truck and transport it out).
4. The whole equipment processing system is equipped with full-automatic electrical control system and equipment fault alarm system, which operates safely and reliably. Usually, there is no need for special personnel to manage, but only need to maintain and maintain the equipment in time.
