FRP winding septic tank

Features: FRP winding septic tank is made of new material FRP. It is ageing resistant, acid and alkali resistant and has a service life of more than 50 years.Fresh feces with high pressure, high compressive strength, no post-management and long slag clearance period enter the first tank from the entrance. Feces in the tank begin to ferment and decompose. Feces can be naturally divided into three layers according to their specific gravity. The upper layer is pasty feces, the lower layer is massive or granular feces, and the middle layer is relatively clear feces. Bacteria and parasite eggs were found in the upper and lower layers of feces. The initial fermented middle layer of feces overflowed to the second pond through the fecal tube, while most of the unfermented feces and feces were retained in the first pond for further fermentation. The feces flowed into the second pool were further fermented and decomposed, the eggs continued to sink, the pathogens gradually died, and the feces were further harmless, resulting in a significantly reduced thickness of the feces and the feces than in the first pool. The excrement from the third pond is generally rotten, and the germs and parasite eggs have been basically killed.Local treatment of sewage should be carried out by installing chemical tanks near buildings. When the building foundation level is lower than the septic tank foundation level, microorganisms attached to the surface of the carrier grow and precipitate sludge. Anaerobic decomposition of sludge under closed anaerobic or anoxic conditions is generally considered. This kind of microbial treatment structure will be the trend of septic tank development to decompose the organic matter in sludge into non-anaerobic decomposition. Machinery, easily converted raw sludge into mature sludge, changed the structure of the sludge, the water content of the sludge, periodically cleared and transported, landfill or used as fertilizer.
