Scope of application:
Preliminary treatment of domestic and fecal sewage in industrial and civil buildings such as residential communities, office buildings, schools, nursing homes, enterprise workshops, and living quarters.
working principle:
Septic tank is a primary treatment structure that uses sedimentation and anaerobic fermentation principles to remove suspended organic matter from domestic sewage. Domestic sewage contains a large amount of impurities such as feces, paper scraps, and pathogens. The suspended solid concentration is 100-350mg/mol, and the organic matter concentration BOD5 is between 100-400mg/mol, with suspended organic matter BOD5 ranging from 50-200mg/mol. Wastewater enters the septic tank and undergoes 12-24 hours of sedimentation to remove 50-60% of suspended solids. The settled sludge undergoes anaerobic digestion for more than 3 months, which decomposes the organic matter in the sludge into stable inorganic substances. The perishable raw sludge is converted into stable mature sludge, changing the structure of the sludge and reducing its moisture content. It is regularly cleared and transported, buried, or used as fertilizer.
Product performance and characteristics:
1. The product is made of excellent fiberglass composite material, which has acid resistance, alkali resistance, tensile resistance, compression resistance, and resistance; Advantages such as mid-range impact, the service life can be synchronized with the building.
2. Good sealing, no leakage, completely preventing pollution caused by groundwater leakage in traditional septic tanks. Simultaneously improving the harm of wet and soft foundation settlement to buildings has good environmental benefits.
3. This equipment adopts structural design and efficient membrane filling technology, with high removal efficiency, small footprint, flexible site selection, and is suitable for the renovation of sewage systems and the establishment of septic tanks in old urban construction areas.
4. The product is lightweight and easy to transport. The product is formed as a whole, without the need for assembly, and can be installed quickly.
5. The product has high compressive strength and can be installed in green lawns or under roads.
