The above ground sewage treatment equipment is generally placed in the outdoor, the more common form of foreign carbon steel, containerized, biological transient disk, etc., these integrated rural sewage treatment equipment process varies. Above ground sewage treatment equipment due to the majority of biochemical treatment process, so you need to take up some space on the ground, the equipment installed on the ground advantages and disadvantages, conducive to fault detection and repair, usually easy to maintain is also relatively simple, very few construction costs, due to the long-term exposure to the wind and rain its life expectancy is also relatively low. In order to prevent low-temperature shutdown, generally need to establish some insulation or heating measures, rainy season to do a good job of anti-electricity measures.
Buried rural sewage treatment equipment as the name suggests is buried in the ground, generally require some civil construction. The use of buried design saves space on the ground, the surface of the ground can be used for a variety of purposes, saving the footprint, and buried sewage treatment equipment, low noise, small impact on the environment, advanced technology so less mud production, easy to use, reduce the amount of manpower labor, but it is because buried in the ground, once the failure occurs, the maintenance of the inconvenience of the summer should be flood-proof.
The main principle of buried integrated wastewater treatment equipment is to use microorganisms to treat domestic sewage. The main removal of compounds in the sewage, is currently one of the most effective means of sewage treatment, can be applied to urban and rural sewage treatment, sewage treatment efficiency. At the same time, in order to ensure the quality of sewage water treatment on the basis of also has a low cost, easy to quickly deal with the characteristics.
The treatment process of buried integrated sewage treatment equipment is as follows: domestic sewage is first picked up through the septic tank, collected by the pipeline network into the regulating pool, filtered into the coarse grating, relying on the pump into the integrated sewage equipment, sewage flows through the anaerobic pool, anoxic pool, aerobic pool, and finally pumped to the disinfection pool, after disinfection, can meet the standards for discharge. The membrane inside the membrane pool through the membrane filtration makes the water and sludge physical separation, to achieve the purpose of water purification. Membrane surface also has microorganisms in the oxygen and organic supply of adequate conditions fixed, and gradually formed biofilm. Biofilm has a strong ability to adsorb, oxidize and decompose organic matter.
