Black and odorous water body riverway slope sponge transformation system
The invention provides a black and odorous water body riverway slope sponge transformation system. The sponge transformation system comprises a rainwater garden and a multi-stage wetland located on the downstream of the rainwater garden; the rainwater garden comprises a foundation pit and a drainage system, the foundation pit is tamped with plain soil, the drainage system is arranged in the foundation pit and used for collecting and draining rainwater, a gravel layer, a pea gravel layer, a coarse sand layer, a medium soil layer and a first soil covering layer are sequentially arranged on the upstream side of the drainage system from bottom to top, and the downstream side of the drainage system is filled with a second soil covering layer; and the multi-stage wetland communicates with a water outlet of the drainage system so as to filter and purify the drained water. According to the system, through the upstream rainwater garden, rainwater discharge is reduced, peripheral pipe networks,structures and water bodies are protected, and waste of water resources is reduced; rainwater is subjected to multi-stage filtration and purification through the rainwater garden and the multi-stage wetland, so that non-point source pollution is reduced, and the self-purification pressure of a riverway is reduced; and the utilization rate of the water resources is increased, and meanwhile a certain attractive effect is achieved on the side slope.
本发明提供了一种黑臭水体河道边坡海绵改造系统，包括：雨水花园和位于其下游的多级湿地；雨水花园包括：基坑和排水系统；基坑采用素土夯实；排水系统置于基坑内，用以对雨水进行收集和外排；排水系统的上游侧由下至上依次有砾石层、豆砾石层、粗砂层、介质土层和第一覆土层；排水系统的下游侧填充有第二覆土层；多级湿地与排水系统的出水口连通，以对排出的水进行过滤和净化。本发明，通过上游雨水花园，减少了雨水外排，对周边管网、构筑物及水体进行了保护，减少了对水资源的浪费；通过雨水花园和多级湿地对雨水的多级过滤和净化，削减了可面源污染，降低了河道的自净压力；提高了水资源利用率的同时，也对边坡起到了一定的美观效果。
