Road rainwater recycling equipment

Abstract

The invention discloses road rainwater recycling equipment. The road rainwater recycling equipment comprises a drainage and permeation device and a rainwater processing device, wherein the drainage and permeation device collects road rainwater in a drainage channel into the rainwater processing device through a processing water inlet pipe; the rainwater processing device comprises an equipment barrel, as well as a grit chamber, a hydrocyclone separation device, a prefilter device and a secondary filter device which are arranged in the equipment barrel and sequentially communicated from bottom to top; the prefilter device and the secondary filter device are connected through a filler supporting plate, and a porous water-out plate is arranged at the top of the secondary filter device; the side edge of the equipment barrel above the secondary filter device is connected with a processing water outlet pipe; and the water outlet of the processing water outlet pipe is connected with a rainwater storage and recycle device. The road rainwater recycling equipment is simple in structure, small in space occupation and good in processed effluent quality, can effectively reduce discharge of runoff rainwater pollutants, can be combined with greening-used land at the periphery of a road, is ecological and environment-friendly, and has a favorable popularization value, and the problems of high urban road flood draining pressure, severe road runoff pollution and rainwater resource loss and the like are solved.

Description

technical field [0001] The invention relates to road rainwater resource utilization equipment, which belongs to the technical field of rainwater resource utilization. Background technique [0002] The total amount of water resources in my country is very low, and the annual average rainfall is about 6 trillion m 3 , of which about 3.2 trillion m 3 Left and right are returned to the atmosphere through soil evaporation and plant emission, leaving about 2.8 trillion m 3 Surface water and groundwater have formed, and my country's per capita water resources are less than 1 / 3 of the world's average level. At present, more than 400 of the more than 600 cities in my country have insufficient water supply, and 110 of them are seriously short of water. The shortage of water resources and the deterioration of water environment have become important factors restricting the development of cities and social progress in our country. Rainwater is the most fundamental, direct, and econom...
