Fiberglass reinforced plastic (FRP) septic tank specifications:
Fiberglass reinforced plastic (FRP) septic tank refers to the synthetic resin as the matrix, glass fiber reinforced materials made specifically for the treatment of domestic sewage equipment. Glass fiber reinforced plastic septic tank is a composite material product that is actively promoted by the state, with the advantages of light weight, high strength, good toughness, corrosion resistance, bright colors, and the finish reaches the mirror effect.
Has far exceeded the ceramics, hard plastic, steel and other materials of similar products, is widely used in chemical, petroleum, construction, textile, aviation, navigation, transportation, electric power, metallurgy, machinery, medical, food, paper, environmental protection and other fields.
Expanded informationSeptic tank process principle:
Septic tank is a use of sedimentation and anaerobic fermentation principle, to remove suspended organic matter in domestic sewage treatment facilities, belongs to the primary transitional life treatment structures. Domestic sewage contains a large number of feces, paper, pathogens... The concentration of suspended solids is 100~350mg/L, and the concentration of organic matter CODCr is 100~400mg/L, of which the concentration of suspended organic matter BOD5 is 50~200mg/L.
The sewage enters into the septic tank after 12~24h of sedimentation, and the suspended matter can be removed by 50%~60%. The sludge precipitated after more than 3 months of anaerobic fermentation decomposition, so that the organic matter in the sludge decomposition into stable inorganic matter, easy to corrupt the raw sludge into a stable cooked sludge, change the structure of the sludge, reduce the water content of the sludge. The sludge is regularly emptied and transported out, landfilled or used as fertilizer.
Requirements: septic tank sedimentation and decay part of the calculated volume of the part, should be in accordance with the "Building Water Supply and Drainage Design Code" (GB50015-2003) Article 4.8.4 ~ 4.8.7 to determine. Sewage retention time in the septic tank should be used 12h ~ 36h. For sewage treatment system without sludge disposal, septic tank volume should also include the volume of stored sludge.
