Abstract

The invention discloses a sewage treatment system, and relates to the technical field of sewage treatment. The system mainly includes a sewage pool, a coarse grid, a grit chamber, a primary sedimentation tank, an adjustment tank, a flocculation tank, a secondary sedimentation tank, an anaerobic tank, an aerobic tank, an anoxic tank, a filtering device and an ecological filter tank, a flocculatingagent is added into the flocculation tank, and the flocculating agent comprises, by weight, 20-45 parts of lignin, 3-7 parts of trioxymethylene, 12-18 parts of triethylenetetramine, 2.5-3 parts of sodium hydroxymethanesulfonate, 6-9 parts of isobutanol, 11-17 parts of 2,3-epoxypropyltrimethylammonium chloride, 5-8 parts of aluminum sulfate, 2.5-3.8 parts of ferrous sulfate, 6-9 parts of zinc chloride and 16-20 parts of polyacrylamide. The system solves the problems of long acting time and poor removal effect of the flocculating agent, and reaches the advantages of fast action and good removaleffect of the flocculating agent.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, more specifically, it relates to a sewage treatment system. Background technique [0002] With the development of the economy and the advancement of urbanization, the discharge of industrial sewage and domestic sewage is also increasing year by year. Generally, there are many enterprises around the rivers in the city, including leather factories, waste engine oil processing factories, electroplating factories and other heavily polluting industries. These enterprises are basically heavy polluting enterprises, such as leather wastewater, with large fluctuations in water quality and quantity, high concentration of suspended solids, easy corruption, large amount of pollution, and wastewater containing toxic compounds such as nitrogen, phosphorus, sulfide and cadmium. The oil spill from the waste engine oil factory also pollutes the water very seriously. Basically, every 1L of engine oil can ...
