Product Overview The overall biological septic tank is made of high-strength glass fiber composite material of glass fiber reinforced unsaturated polyvinyl acetate resin as the main material, and the advanced FRP winding process is used to make the cylinder plus concave and convex wheel-shaped head structure. ANSYS structural calculation software is used to optimize the strength, steel strength, and advanced technology. It has the characteristics of light weight, high strength, good corrosion resistance, no leakage, no pollution, good formability, long service life, etc. The two ends of the pool body are provided with inlet and outlet pipes and an inspection wellhead on the top of the tank. Scope of application Preliminary treatment of living and fecal sewage in residential residential buildings such as office buildings, schools, nursing homes, enterprise workshops, living rooms, etc. Working Principle A septic tank is a kind of primary treatment structure that uses the principles of precipitation and anaerobic fermentation to remove suspended physical organic matter from domestic sewage. Domestic sewage contains a large amount of impurities such as feces, confetti, pathogens, etc. The suspension solid concentration is 100-350 mg/, and the organic matter concentration BOD5 is between 1000 mg, of which the suspended organic matter BOD5 enters the sewage at 50=20mg. The septic tank is precipitated for 12-24h to remove 50%-60% of suspended matter. After more than 3 months of anaerobic digestion of the precipitated sludge, the organic matter in the sludge is decomposed into stable inorganic matter, and the perishable raw sludge is converted into stable cooked sludge, the structure of the sludge is changed, and the water content of the sludge is reduced, and the water content of the sludge is reduced, and the water content of the sludge is regularly cleared and transported, landfilled or used as fertilizer. Product performance and characteristics 1. The product is made of high-quality FRP composite material, which has the advantages of acid resistance, alkali resistance, tensile resistance, compression resistance, impact resistance, high strength, and the service life can be synchronized with the building. 2. Good sealing, no leakage, and completely prevent pollution caused by groundwater leakage in traditional septic tanks. At the same time, the harm to buildings caused by wet and soft sinking of the foundation is improved, and it has good environmental protection benefits. 3. This equipment adopts unique structural design and efficient hanging film filler, high removal efficiency, small footprint, flexible site selection, and is especially suitable for the renovation of the sewer system in the old city construction area to set up a septic tank. 4. The product is light in weight and easy to transport. The product is molded as a whole, no assembly is required, and installation is quick. 5. The product has high compressive strength and can be installed in the green lawn or under the road.
