Abstract

The invention discloses a grading and filtering device for collecting and retaining rainwater in cities, which comprises a casing, and a water inlet is opened on the top of the casing, an inclined water retaining wing is arranged on the top of the casing, and a guide is fixedly arranged inside the casing. A water plate and two water baffles, and the two water baffles are symmetrically located on both sides of the water guide plate, and the middle part of the water guide plate is equipped with an impurity removal mechanism, and the impurity removal mechanism includes a rotating connection with the side wall of the housing support plate. The present invention can classify and filter the collected rainwater, concentrate the larger impurities in the rainwater in the impurity removal area, and concentrate the small impurities such as sediment in the sand collection area, so as to facilitate the cleaning and secondary recycling of impurities, and at the same time The more dirty rainwater flows out from the sewage outlet, and the rainwater with less impurities flows out from the drain outlet, which can realize the reuse of water resources, and the equipment requires very little electric energy during operation, which has the advantages of green energy saving.

Description

technical field [0001] The invention relates to the technical field of rainwater filtration and recovery, in particular to a grading and filtering equipment for collecting and retaining rainwater in cities. Background technique [0002] In order to improve the shortage of water resources, most cities will collect rainwater and use it as reserve water for cleaning, irrigation and other activities. However, the collected rainwater generally contains more impurities and cannot be used directly. Carry out preliminary filtration and separation, as in the working method of a kind of municipal construction rainwater recovery and treatment device proposed in the patent document CN109045834A, first filter the large impurities in the rainwater or domestic sewage through the coarse filter screen, and then The rainwater or domestic sewage is filtered twice through the fine filter plate and activated carbon filter plate arranged at an angle, so as to realize the preliminary treatment of ...
