Sewage and flood flow distributing system for ecologically purifying domestic sewage

Abstract

A flood and sewage flow distributing system for ecologically purifying domestic sewage comprises a drainage groove (1), a flood draining groove (2), a drainage hole (3) and a flow distributing dam (4). The drainage groove (1) is in the shape of an inverted trapezoid, and an inlet of the drainage groove (1) is wide while an outlet of the drainage groove (1) is narrow; water stopping walls (5) are arranged on two sides and at the bottom of the drainage groove (1), the flow distributing dam (4) is located between the water stopping wall on one side of the drainage groove (1)and the water stopping wall at the bottom of the drainage groove (1), the flow distributing dam (4), the water stopping wall on one side of the drainage groove (1) and the water stopping wall at the bottom of the drainage groove (1) form a triangle, and the flood draining groove (2) is formed in an area among the flow distributing dam (4) and the water stopping walls (5); the diameter of the drainage hole (3) is 0.15m; a sand stopping screen (6) is mounted at an outlet end of the drainage hole (3), a filter screen is circular, the aperture of meshes is 0.002m, a grid screen (7) is mounted at an inlet end of the drainage hole (3) and is circular, the diameter of the grid screen (7) is 0,15m, and the aperture of grids is 0,02m; and the flow distributing dam (4) is required to be higher than the upper edge of the drainage hole by 0,2m, and is higher than the stopping wall of a water outlet of the flood draining groove by 0,2m. The flood and sewage flow distributing system is simple and reasonable in structure, low in manufacturing cost and high in popularization and application values, and can be widely applied to various domestic sewage ecological purifying systems.

Description

technical field [0001] The invention relates to a domestic sewage purification technology system, which belongs to the field of environmental engineering and environmental science, and is used for flood and sewage diversion in domestic sewage ecological purification systems (such as artificial wetlands, medium adsorption, stabilizing ponds, and front storage). Background technique [0002] With the continuous development of society and economy, the problem of water pollution is becoming more and more serious, and sewage treatment has become a key issue that human beings urgently need to solve. Sewage ecological purification technology (such as artificial wetland, media adsorption, stabilization pond, front storage) is one of the more popular new technologies in sewage treatment in recent years. The investment and daily operating costs are much lower than conventional sewage treatment plants, so they are gradually widely used in the treatment of industrial and agricultural wa...

AI Technical Summary

Problems solved by technology

However, the inflatable rubber dam is easily damaged and the maintenance cost is high; while the overflow pool cannot efficiently separate the flood, which may easily cause the purification system to be washed away by the flood and be damaged

In some big cities, rainwater and sewage are collected separately, but the amount of work is large and the cost is expensive.
