Scope: residential quarters, office buildings, hotels, schools, hospitals, barracks, public toilets, residential renovation and other places municipal sewage treatment, waste water treatment, food processing enterprises in the technical principles: fiberglass septic tanks and the use of high-strength polymer materials Septic overall cylindrical glass fiber composite made of steel, compared with traditional brick and concrete septic tank leakage has really rigor, quality, easy to transport, high compressive strength, acid long life, fast installation and other advantages. Cylindrical septic effective use bulky, and the ends of the barrel with a T-shaped ribs, both ends of the external wheel-type head, convex surface design. This structure can improve the strength and pressure strength of the cell body. Upper body out of the water tank has a hole and raking, the pool with a membrane compartment divided into primary sedimentation tank, secondary sedimentation tank and treatment pool of three parts. Compartment plate is provided with padding sewage treatment stuffing box packing, packing for vinylon filaments having elasticity. Sewage from septic tanks into the cell body in the upper intake level sedimentation tank, sink into the bottom than the major part of the conduct of manure treatment, a small proportion of the upper part of the float on the water, you can remove from the clean-up hole, the upper effluent water circulation channel stuffing box side compartment into the stuffing box installed on the board, rather than hanging enriched water filler microorganism that degradation of organic matter in water. Since the change of DC pan pan hydration water circulation principle manure, sewage increase in the residence time of the cell body, in contact with the filler material degradation sewage longer, a higher degree of degradation of organic matter, so that the discharge of wastewater BOD index greatly reduced.
