The invention belongs to the technical field of garden
water collection, and particularly relates to a municipal garden rainwater collection and treatment device. The device comprises a box body, wherein a first partition plate and a second partition plate are fixedly connected to the bottom of the inner wall of the box body, the box body is divided into a
precipitation cavity, a purification cavity and a
water storage cavity by the first partition plate and the second partition plate, one side of the
precipitation cavity communicates with a feeding
pipe, and the top of the feeding
pipe is inthreaded connection with a
pipe cover. According to the device, rainwater is stored through the combined action of
water storage plates, supporting plates, a first water inlet pipe, a second water inlet pipe, the
precipitation cavity, the purification cavity and the
water storage cavity, the filter plates have a certain inclination angle through the combined action of the water storage plates, thesupporting plates, side plates and the filter plates, therefore the filter plates play roles in filtering external impurities, and under the action of the inclination angle, the impurities falling onto the filter plates are flushed off from the filter plates due to the gravity of the impurities and the flushing of rainwater, so that the impurities are prevented from being accumulated on the filter plates to cause the blockage of the filter plates.
