The glass reinforced septic tank is made of glass fiber reinforced unsaturated polyester resin high-strength glass fiber composite material as the main material. The advanced glass fiber reinforced plastic winding process is used to produce a cylinder-shaped structure with an uneven surface and a wheel-shaped head. Simplified wall thickness and distance between discs are adopted by ansVs structural calculation software for strength, optimized steel design, unique structural design, and advanced technology. It has light weight, high strength, good corrosion resistance, no leakage, and no pollution. , Good moldability, long service life and so on. There are inlet and outlet pipes at the two ends of the pool body and inspection wellheads at the top of the tank. The pool is divided into compartments by compartment boards, and a circulating flooding device is installed to increase the retention time of sewage and improve the decay effect.
Scope of application: residential and residential buildings, office buildings, schools, nursing homes, corporate workshops, living rooms and other industrial civil buildings, such as living and preliminary treatment of fecal sewage.
Working principle: The septic tank is a kind of primary treatment to remove suspended organic matter in domestic sewage by the principle of sedimentation and anaerobic fermentation. The domestic sewage in the structure contains a large amount of impurities such as feces, paper scraps, pathogens, etc., and the suspended solids concentration is 100 -350mg children, organic matter concentration BOD5 between 100-400mg children, of which suspended organic matter BOD5 is 50-200mg children. After the sewage enters the septic tank for 12-24 hours, 50% -60% of the suspended matter is removed. The sedimented sludge undergoes anaerobic digestion for more than 3 months, and the organic matter in the sludge is decomposed into stable inorganic matter. The perishable raw sludge is converted into stable mature sludge, which changes the structure of the sludge and reduces In order to determine the moisture content of the sludge, it is regularly removed for transportation, landfilled or used as fertilizer.
This equipment adopts a unique structural design and efficient hanging film filling, which has high removal efficiency, small floor area, and flexible site selection. It is particularly suitable for retrofitting sewer systems in old urban construction areas to set up septic tanks.
