River in-situ water quality improving structure
The invention relates to a river in-situ water quality improving structure, which comprises a riverway, and the tail end of the riverway is converged into a main reservoir. A gravel treatment section,an aeration oxygen dissolving section and a front reservoir purification section are sequentially arranged in the riverway in the river direction. The gravel treatment section comprises a small-diameter gravel layer, a medium-diameter gravel layer and a large-diameter gravel layer, which are sequentially laid upwards from the bottom of the river channel; the aeration oxygen dissolving section comprises a plurality of aeration devices arranged in the riverway; the front reservoir purification section comprises an overflow dam arranged in the riverway, the overflow dam divides the front reservoir purification section into front reservoir areas, the front reservoir areas are communicated with the main reservoir, and aquatic plants are planted in the front reservoir areas. The method is an ecology simulated artificially strengthened method for an enhanced ecological natural river water treatment, pollutants are removed by the gravel treatment section, the aeration oxygen dissolving section and the front reservoir purification section, compared with the prior art, the structure is simpler, the practicability is good and the water can be effectively purified.
本发明涉及一种河流原位水质提升结构，包括河道，河道的末端汇入主水库；在河道内沿河流方向依次设有砾石处理段、曝气溶氧段和前置库净化段；砾石处理段包括由河道底部向上依次铺设的小径砾石层、中径砾石层和大径砾石层；曝气溶氧段包括设于河道内的若干曝气装置；前置库净化段包括设于河道内的溢流坝并由溢流坝划分隔设形成前置库区域，前置库区域与主水库连通，前置库区域内种植有水生植物。本发明是对天然河道水处理的一种人工强化，是一种模仿生态、强化生态自然净化水质过程的方法，对污染物的去除通过砾石处理段、曝气溶氧段和前置库净化段多重作用，结构较现有技术更简单，实用性好，并能有效净化水质。
