Black and odorous water treatment method

The invention discloses a black and odorous water body treatment method, which comprises river bottom sediment dredging and river sewage enhanced flocculation repair treatment. The method can effectively repair black and odorous water bodies, remove suspended substances in black and odorous river channels, reduce COD in river sewage and promote precipitation of phosphorus through sediment dredgingand enhanced flocculation repair technologies. Thus, dissolved nitrogen is effectively removed. In addition, the flocculation sediment reduces the chromaticity of water, so that the black and odoroussewage is clear. 本发明公开了一种黑臭水体治理方法，包括河底底泥疏浚和河道污水强化絮凝修复处理，本发明通过底泥疏浚和强化絮凝修复技术可有效修复黑臭水体，去除黑臭河道中悬浮物质，降低河道污水中COD，促进磷的沉淀；有效脱除溶解性氮；絮凝沉淀，降低水的色度，使黑臭污水清澈。
