Ecological overflow weir for purifying water quality

Abstract

The invention belongs to the technical field of sewage treatment, and particularly relates to an ecological overflow weir for purifying water quality, which comprises dam piers, an upstream water retaining weir and a downstream purifying device, when the ecological overflow weir is used, the water level is increased before the water flow reaches the water retaining weir, the fall of the water flow is increased, and the contact between the water flow and air is increased, so that the aeration in the water body is improved; water diversion teeth are uniformly arranged at the top of the water retaining weir, so that water flow uniformly and crossly flows into the aeration tank along the water diversion teeth, the contact between water and air is further expanded, suspended solids in the water can be prevented from sinking, and the contact between organic matters in the water and microorganisms and dissolved oxygen is enhanced, thereby ensuring that the microorganisms in the water have sufficient dissolved oxygen. Organic matters in the sewage are oxidized and decomposed, so that water pollution is effectively improved and treated; the multiple permeable abutments are arranged at intervals in the transverse direction, the adjacent permeable abutments are connected together through the steel wire net frames to form the combined permeable dam body, the permeable dam body is filled with the sludge carrier, and the sludge carrier can effectively adsorb sludge and can purify water flow, so that the purposes of effectively treating sewage and purifying water are achieved.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to an ecological overflow weir for purifying water quality. Background technique [0002] With the continuous expansion of cities in my country and the rapid development of industry and agriculture, or affected by surface sewage and industrial drainage, many domestic rivers have problems, and the water quality of river courses has been in a poor state for a long time. The purpose of purifying water. [0003] Although the traditional overflow weir has been widely used in the field of lake and river engineering, many problems have not been considered. The sewage has a certain landscape ecological overflow weir to solve the problem. Based on this, it is necessary to study an ecological overflow weir to purify water. SUMMARY OF THE INVENTION [0004] Aiming at the defects and problems existing in the existing equipment, the present invention provides an ecologica...

Problems solved by technology

[0004] Aiming at the defects and problems existing in the existing equipment, the present invention provides an ecological overflow weir for purifying water, which effectively solves the problem that although the traditional overflow weir in the existing equipment has been widely used in lake and river engineering fields, many The problem has not been taken into account, the water pollution problem is serious, its ecological benefits are poor, and it is obviously insufficient in purifying water quality and beautifying the landscape.
