Flocculation coupling hierarchical overflowing method for improving water quality of Yangshan rivers and lakes and dam body
The invention belongs to the field of river and lake water body remediation, and relates to a flocculation coupling hierarchical overflowing method for improving the water quality of Yangshan rivers and lakes and a corresponding dam body. The assembly type flocculation coupling hierarchical overflow dam for reducing silt and pollutants carried by water and soil loss in situ comprises a dam foundation, a dam front flocculation facility and a hierarchical filtering main body, and the dam foundation comprises a dam foundation body and a turf layer; the filtering main body comprises a pervious concrete layer, a quartz sand layer, a functional material layer, a pervious concrete layer and a turf layer; the dam front flocculation facility comprises an impermeable baffle; the impermeable baffle is fixedly connected with the filter main body and the mountain body. Under the conditions that the natural landscape is not influenced, the disassembly is convenient, and the construction and operation cost is low, the effects of hierarchical filtration, interception, adsorption degradation and the like are played to the maximum extent. The adopted filter material can be replaced or modified according to requirements, can be used for removing various pollutants and reducing pollution such as nitrogen, phosphorus, turbidity and COD (Chemical Oxygen Demand), and does not influence landscape and ecological risks.
本发明属于河湖水体修复领域，涉及一种用于改善依山河湖水质的絮凝耦合层级过流方法及对应的坝体。本发明提供的原位削减水土流失携带泥沙和污染物的装配式絮凝耦合层级过流坝，包括坝基、坝前絮凝设施和层级过滤主体，所述坝基包含坝基和草皮层；所述过滤主体包含透水混凝土层、石英砂层、功能材料层、透水混凝土层和草皮层；所述坝前絮凝设施包含不透水挡板，不透水挡板通过与过滤主体和山体连接固定。本发明在不影响自然景观，且拆卸方便、建设和运营成本低的情况下，最大化发挥层级过滤、截留和吸附降解等作用。所采用的滤料可以根据需求更换或改性，可用于去除多种污染物，降低氮、磷、浊度和COD等污染，不影响景观和生态风险。
