Municipal rainwater regulation and storage system

Abstract

The invention discloses a municipal rainwater regulation and storage system, and relates to the field of rainwater treatment. The system comprises a storage pond and a purifying device; the purifyingdevice divides the storage pond into a water storage pond and a water discharging pond; a cover plate covering the water discharging pond and the purifying device is arranged on the storage pond; a supporting rod is vertically arranged in the reservoir; the outer wall of the supporting rod is slidably connected with a sliding pipe; the outer wall of the sliding pipe is slidably connected with a sliding sleeve; a cleaning device is arranged in the water storage pool and comprises a plurality of mounting rods connected end to end; sleeve pipes are arranged on the mounting rods; scrapers are arranged on the sleeve pipes; intercepting plates are arranged on the edges of the scrapers; pull rods are hinged to the sides, deviating from the water storage pond, of the scrapers; and the upper ends of the pull rods are hinged to sliding sleeves. The municipal rainwater regulation and storage system has the following advantages and effects that attached impurities on the inner wall of the water storage pond are stripped in time through the cleaning device, and the treatment burden of the purification device is reduced; meanwhile, the rainwater treatment effect and efficiency are improved, andrainwater is treated more thoroughly.

Description

technical field [0001] The invention relates to the field of rainwater treatment, in particular to a municipal rainwater regulation and storage system. Background technique [0002] The rainwater storage tank is a rainwater collection facility. Its main function is to temporarily store the peak flow of rainwater runoff in it, and then slowly discharge the rainwater from the storage tank after the maximum flow rate drops. It can not only avoid the rainwater flood peak, realize the recycling of rainwater, but also avoid the pollution of the receiving water body by the initial rainwater, and also play a positive role in the drainage scheduling between drainage areas. [0003] Chinese patent CN107246061A discloses a rainwater storage device, which includes a storage tank, a sewage pipe is arranged below the storage tank, and a filter is provided inside the storage tank, and activated carbon is provided on the right side of the filter Adsorption layer, the right side of the acti...

Problems solved by technology

[0005] However, rainwater is often mixed with some dust and impurities. When the rainwater accumulates in the storage tank, the dust and impurities will be suspended on the liquid surface, and as the liquid level gradually drops, some impurities will adhere to the inner wall of the storage tank.

If the impurities are not cleaned up in time, the impurities will cause the rainwater in the storage tank to deteriorate, thereby increasing the processing burden of the filter device and the purification layer, and reducing the rainwater treatment efficiency, which needs to be improved
