Riverway bypass water purification wetland system
The invention relates to a riverway bypass water purification wetland system. The system comprises a drainage water purification section, a circuitous water purification section and a drainage water purification section which are sequentially communicated, wherein a water outlet of the drainage water purification section is communicated with the main river channel; the drainage water purificationsection comprises a drainage channel communicating a water inlet and the main river channel, gravels laid in the drainage channel, and gravel tumbling weirs and a plurality of first spur dikes which are sequentially distributed in the water flow direction; the first spur dikes are sequentially arranged on the two sides of the drainage channel in a staggered mode to form a snake-mouth-shaped firstpurified water channel, and the heads of the first spur dikes are obliquely arranged in the water flow direction. Sewage of the riverway sequentially flows into the circuitous water purification section and the drainage water purification section to be purified through water flow purified by the drainage water purification section and then flows into the main riverway again, multi-stage circuitousoperation is completed, and the riverway water quality purification effect is improved; and the plurality of first spur dikes form a snake-mouth-shaped first water purification channel with small circuitous water flow, so that the flow velocity can be reduced, the reflux is reduced, the contact time of water and a substrate is prolonged, the water dissolved oxygen is increased, and the river water purification effect is further improved.
本发明涉及一种河道旁路净水湿地系统，包括依次连通的引流净水段、迂回净水段和排流净水段，排流净水段的排水口与主河道连通，引流净水段包括进水口与主河道连通的引流渠道、铺设于引流渠道内的砾石、沿水流方向依次布设的砾石滚水堰和多个第一丁坝，第一丁坝沿引流渠道两侧依次交错排列、并形成蛇口型的第一净水通道，第一丁坝的头部沿水流方向倾斜设置。河道的污水通过引流净水段净化后的水流，相继流入迂回净水段和排流净水段进行净化后，再重新流入主河道，完成多级迂回，提升河道水质净化效果；且多个第一丁坝构成小迂回水流的蛇口型第一净水通道，可阻滞流速，减少反流，增加水体与底质的接触时间和水体溶氧，进一步提升河道水质净化效果。
