Septic tank effluent quality, impurity removal, testing, data processing effects observed data better than water and wastewater treatment facilities are complete. Should choose a representative categories throughout the building, in different seasons, different times on the same day into a septic tank, the water quality, the treatment effect fully tested and tested periodically according to changes in domestic sewage component to enrich and improve the design information Wuhan fiberglass septic installation guide engineering design. Mechanical winding FRP tanks generally horizontal cylindrical shape, both ends of the head commonly used mechanical properties of concave-convex surface design, fiberglass septic tanks Wuhan model, with internal partitions, Caidian fiberglass septic tanks, barrel mechanical winding process, high compressive structural design. Mechanical winding FRP septic is the principle of settling and removal of sewage anaerobic fermentation of organic matter in suspension of processing equipment. Mainly applied to the treatment of municipal sewage residential buildings, towns, office buildings, hotels, schools, hospitals, military units, scenic areas, villas and so on. Septic is a use of the principle of sedimentation and anaerobic fermentation, to remove suspended organic matter sewage treatment facilities, part of the primary process of transitional living structures. Sewage contains large amounts of waste, paper, insect pathogen ... suspended solids concentration of 100 ~ 350mg / L, Wuhan fiberglass septic standards, CODCr concentration of organic matter between 100 ~ 400mg / L, which suspended organics BOD5 concentration of 50 ~ 200mg / L. After precipitation of sewage into the septic tank 12 ~ 24h can remove 50% to 60% of the suspended solids.
