Product Description 
 Scope: 
 Residential buildings, office buildings, schools, nursing homes, business workshops, living rooms and other industrial civil life, the preliminary treatment of sewage waste. 
 How it works: 
 Septic tank is a principle of the use of sedimentation and anaerobic digestion to remove suspended solids in domestic sewage primary treatment of most organic structures, sewage contains large amounts of manure, litter, insect pathogens and other impurities, solids concentration of suspended solids 100 - 350mg child, BOD5 concentration of organic matter between children in the 100-400mg, one of the organic matter suspended in the 50-200mg BOD5 children. Sewage into the septic tank after 12-24h of precipitation 50% -60% removal of suspended solids. Sludge settling down after 3 months of anaerobic digestion, the sludge in the decomposition of organic matter into stable inorganic, easy ** raw sludge into a stable mature sludge, changing the structure of the sludge, reduce the moisture content of sludge, regular Qingtao Sinotrans, landfill or used as fertilizer. 
 Product performance and features: 
 1, the product of high quality FRP composite materials, with acid, alkali resistance, pull, compressive strength, resistance; in the attack, high strength, service life can be synchronized with the construction. 
 2, sealing, no leakage, thoroughly traditional septic tanks to prevent leakage of groundwater pollution generated. While improving the marshy ground subsidence hazards of the building, with a better environmental benefits. 
 3, the device features a unique design and high-biofilm fill subjects, removal efficiency, small footprint, site selection and flexible, especially suitable for the transformation of the old city sewer system construction zone set up septic tank. 
 4, light weight, easy to transport. Forming the product as a whole, without assembly, installation and quick. 
 5, the product of high compressive strength, can be installed in the green lawn, but also can be installed under the road.
