Gravity driving pressure sponge type rainwater buffer system

Abstract

The invention discloses a gravity driving pressure sponge type rainwater buffer system. The system comprises a collector, a disk water distributor, a drainage pipe and a water escape valve. The collector comprises a first collector body and a second collector body. The lower end of the first collector body is fixedly connected with the upper end of the second collector body. The disk water distributor is arranged at the position of a joint between the first collector body and the second collector body. The disk water distributor comprises a pressure detection device and a driving device. The drainage pipe communicates with the lower end of the second collector body. The water escape valve is arranged at a joint between the drainage pipe and the second collector body. According to the gravity driving pressure sponge type rainwater buffer system, the disk water distributor and the gravity self-control water escape valve run cooperatively, the process that rain enters the drainage pipe ofrainwater can be delayed, the retention time of rainwater can be prolonged, and the pressure caused to a sewage treatment plant by instantaneous rainfall is reduced to the maximum degree. Because a rainwater collection device is placed under a road surface innovatively, waste of land is reduced.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a gravity-driven pressure sponge type rainwater buffer system. Background technique [0002] At present, most of the sewage treatment plants in my country deal with the instantaneous influx of a large amount of rainwater in the rainy season, which affects or even breaks the normal operation of the sewage treatment plant. period; b control the influent water volume to ensure that the lifting water volume is equal to the usual water volume; c change the process route to ensure the organic carbon source in the biochemical section to meet the growth needs of microorganisms; d reduce the dissolved oxygen in the aeration tank to avoid sludge disintegration or collapse ; e to adjust the reflux; f to supplement nutrients and add carbon sources; g to re-cultivate and resume operation. [0003] The construction of sponge city is a "new rainwater management model" explored in my cou...
