Flow guide type sewage deep treatment method

Abstract

The invention discloses a flow guide type sewage deep treatment method, which comprises the following operation steps: S1, precipitation is performed, wherein sewage is input into an efficient precipitation tank, and is subjected to static precipitation for 4 to 8 hours; S2, filtering is performed, wherein the precipitated effluent is input into a left water distributor or a right water distributor in a constructed wetland through a control valve V or a control valve VI, and sewage and wastewater are uniformly distributed in the constructed wetland and are filtered; S3, the sewage and wastewater purified by the constructed wetland are gathered into a water return pipe through a left side or right side collecting pipe, and the water body is guided into a water collecting tank and is subjected to standing and storage; and S4, the water body in the water collecting tank enters a disinfection channel through a control valve II, is disinfected, and then is discharged after reaching the standard. According to the invention, the effect of the collecting tank is fully utilized, so that the problem that the traditional constructed wetland collecting tank is single in function is effectivelysolved; remote control is achieved through the automatic electric valve, so that other power is reduced, operation is convenient; and construction is easy, the manufacturing cost is low, the change of the flow guide direction is fully utilized, and backwashing with reverse water inflow is achieved.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a diversion type sewage deepening treatment method. Background technique [0002] The sewage treatment process can effectively treat urban domestic sewage and park industrial wastewater, and prevent sewage and pollutants from flowing directly into waters. It is of great significance to improving the ecological environment, improving the urban living environment and industrial park grade, and promoting economic development. At present, domestic sewage treatment plants require more and more stringent drainage indicators, especially in national parks and water-deficient areas, sewage treatment plants are required to raise their standards. Therefore, it is necessary to select an appropriate sewage advanced treatment process in combination with the actual conditions of the local sewage water quantity, water quality, temperature, climate, meteorology, geography, an...

Problems solved by technology

[0003] In the process of advanced treatment of sewage, it needs to be filtered through the filter tank, but the current filtration system generally takes a long time, the operating cost is high, and the filter material is easy to block. The problem is serious, resulting in low efficiency of advanced sewage treatment. In order to improve the efficiency of urban sewage and industrial park sewage advanced treatment, a new type of sewage advanced treatment technology is needed
