Problems solved by technology

With people's recognition of sponge cities, major cities have begun to focus on the construction of sponge cities and rain gardens to improve the drainage and water storage capacity of urban areas. With the acceleration of urbanization, urban waterlogging problems It is becoming more and more serious, and the demand for sponge cities is getting higher and higher. The existing rainwater collection process does not effectively filter and recycle the sundries in the rainwater on the surface, which makes the system prone to blockage after running for a certain period of time, and then It affects the normal operation of the pipe network. Therefore, in view of the above status quo, it is urgent to develop a rainwater recycling and purification system based on rain gardens to overcome the shortcomings in current practical applications.

Abstract

The present invention relates to the technical field of sponge city, in particular to a rainwater garden-based rainwater recovery, purification and drainage system, including a water collection and filtration device, a flow discarding device connected to the water outlet of the water collection and filtration device through a pipeline, a water purification system and a water storage Pool; the outlet pipe of the waste flow device is connected with the municipal rainwater waste flow pipe, and the water collection and filtration settings include: the downpipe, which is located on the inside of the ground, and the output end is connected to the drainage pipe; the top cover is detachably connected with the downwater pipe; the filter mechanism, It is arranged inside the downpipe; and the dredging recovery mechanism is arranged outside the downpipe; wherein, the dredging and recovery mechanism includes: a connection box; a dredging component; a driving component; and a recovery component. The water collecting device of the present invention collects rainwater, and under the action of the flow discarding device, the relatively dirty rainwater in the early stage of flow is discarded. Combined with the water purification system, the filter material is used to adsorb heavy metals and other pollutants in the water body, and the water collection filter is set to filter and remove impurities in the rainwater, and finally the purified rainwater is stored in the storage tank.

Description

technical field [0001] The invention relates to the technical field of sponge cities, in particular to a rainwater garden-based rainwater recycling and purification system. Background technique [0002] Sponge city is a new generation of urban stormwater management concept. It refers to the city's good "elasticity" in adapting to environmental changes and responding to natural disasters caused by rainwater. It can also be called "water elastic city". When it rains, it absorbs, stores, infiltrates, and purifies water, and "releases" the stored water for use when needed. [0003] The rain garden refers to making full use of the natural or artificially excavated shallow green space in the city, guiding the rainwater from the roof or the ground to gather here, purifying the rainwater through the comprehensive action of plants and sand, and opening up the ground surface during the slow infiltration process. It is a small-scale ecological green land landscape with the main form o...
