Ecological overflow weir for purifying water quality
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.
本发明属于污水处理技术领域，具体涉及一种净化水质的生态溢流堰，包括坝墩、上游的挡水堰和下游的净化装置，使用时水流到达挡水堰前的水位增高，加大了水流的落差，增加了水流与空气的接触，从而提高水体中的曝气，挡水堰的顶部均匀设置有分水齿，使得水流沿其均匀交叉流至曝气池内，进一步扩大水与空气的接触，可以防止水内悬浮体下沉，加强水中有机物与微生物及溶解氧接触的目的，从而保证水中微生物在有充足溶解氧的条件下，对污水中有机物的氧化分解作用，有效改善治理水污染；多个透墩台沿横向间隔布置，钢丝网架将相邻的透墩台连接在一起形成组合式透水坝体，污泥载体填充在透水坝体内，污泥载体能够有效吸附污泥，可以对水流进行净化处理，达到有效治理污水，净化水质的目的。
