Embodiment Construction
[0037] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0038] Such as figure 1 Shown: a rainwater collection and purification system for a sponge city, including a rainwater collection tank 1, a preliminary filter device 2, a sterilization device 3, a clarification tank 4, a filter 5 and a clean water collection tank 6 arranged in sequence.
[0039] When the above collection and purification system is applied to the sponge city, the rainwater collection tank 1 is used to collect rainwater. Then, the water pump is used to inject the rainwater in the rainwater collection tank 1 into the preliminary filter device 2, and the sediment in the rainwater is filtered by the preliminary filter device 2.
[0040] Then, after the rainwater is sterilized by the degerming device 3 , the rainwater is coagulated and sedimented by the clarifier 4 . Finally, after the rainwater is finally filtered by the filter 5, the rainwater ...

The invention discloses a rainwater collection and purification system for a sponge urban, and relates to the field of rainwater purification treatment, wherein the system comprises a rainwater collection pool, a primary filtration device, a sterilization device, a clarification pool, a filter and a purified water collection pool, and the rainwater collection pool, the primary filtration device, the sterilization device, the clarification pool, the filter and the purified water collection pool are sequentially arranged. According to the present invention, by setting the continuous filtration,sterilization, clarification and re-filtration process, the rainwater purification treatment is achieved, and the impurity content and the bacteria content in the rainwater are reduced, such that thetreated rainwater can be directly utilized without secondary pollution to the ecological environment so as to maintain the ecological balance.
Description
technical field [0001] The invention relates to the field of rainwater purification and treatment, in particular to a rainwater collection and purification system for a sponge city. Background technique [0002] Sponge city refers to a city that can be like a sponge and has good "elasticity" in terms of adapting to environmental changes and responding to natural disasters. It mainly absorbs, stores, infiltrates, and purifies water when it rains. Release and take advantage of it. [0003] After the traditional sponge city collects rainwater, it often uses the rainwater directly. At this time, the impurities and bacteria carried in the rainwater will cause secondary pollution to the ecological environment, thus destroying the ecological balance, which needs to be improved. Contents of the invention [0004] The object of the present invention is to provide a rainwater collection and purification system for a sponge city, which has the effect of maintaining ecological balanc...
