FRP winding septic tank

Integral biological septic tank is glass fiber reinforced unsaturated polyester resin for the high strength glass fiber composite materials as the main material, using advanced FRP winding process making barrel with concave convex wheel shaped head structure. The wall thickness of the cylinder and the distance between the plate and the plate are used to calculate the strength of the ANSYS structure, the optimum design of the steel, the unique structure and the leading technology. The technology has the characteristics of light weight, high strength, good corrosion resistance, no leakage, no pollution, good formability, long service life and so on. At both ends of the tank body is provided with a inlet and outlet pipe and tank is arranged on the top of the check wellhead, pool with partition board lattice, and a loop flashing device to increase sewage retention time, so as to improve the effect of corruption.

Scope of application

The preliminary treatment of the life of the industrial and civil buildings, such as residential building, office building, school, nursing home, enterprise workshop, life, etc…

Product performance and characteristics

1.Products using high-quality FRP composite materials manufacturing, with a cid, alkali resistance, resistance to tensile, compressive strength, impact resistance, high strength, service life and building synchronous.

2.Good sealing, no leakage, completely prevent the traditional septic tank pollution caused by groundwater seepage. At the same time, the damage to the building is improved by the wet and soft sinking of foundation, which has good environmental benefits.

3.The equipment adopts the unique structural design and, hanging membrane packing, high removal efficiency, covers an area of small, flexible site selection, especially suitable for building area of the old city reconstruction in sewer system established septic tank.

4.Product light weight, easy to transport. Product integral forming, no need to assemble, installation fast.

5.Products with high compressive strength, can be installed in the green lawn, can also be installed in the road.

Working principle

Septic tank is a kind of using precipitation and anaerobic fermentation principle was used to remove the primary treatment of sewage suspended solids in the organic matter to build a life sewage containing large amounts of excreta, scraps of paper, parasite and other impurities, the suspended solids concentration between 100-350mg/L. The suspension is organic BOD5 in 20-200mg/L. Sewage into the septic tank by 12-24h precipitation, removal of suspended solids 50%-60%.Precipitated sludge through anaerobic digestion of more than 3 months, the sludge organic matter decomposition into stable inorganic material, easy to corruption of raw sludge into stable ripe sludge, changing the structure of sludge, reducing the moisture content of sludge, regular Qingtao Sinotrans, landfill or used as fertilizer.
