Rainwater collection storage utilization process

Abstract

The invention discloses a rainwater collection storage utilization process. The process comprises the following steps of: collecting rainwater on a roof, intercepting pollutants in the rainwater, performing initial rainwater discarding, regulating and storing the rainwater, filtering the rainwater, disinfecting the rainwater, and feeding into a recycling water tank for later use, wherein in the step of initial rainwater discarding, the rainwater of which the pollutants are intercepted is introduced into a rainwater discarding pool, dirt deposited on the lower part of the rainwater discarding pool is discharged from a drain pipe, and water on the upper part of the rainwater discarding pool is introduced into a rainwater regulation and storage pool for regulation and storage; in the step of regulating and storing the rainwater, the water in the rainwater regulation and storage pool is regulated and stored, and when the rainwater stored in the pool is excessive, the excessive water is introduced into a municipal drainage system; and in the step of filtering the rainwater, the rainwater is filtered by a multi-medium filter. By the process, most of pollutants in rainwater runoff can be controlled, and the load of subsequent treatment equipment is reduced; the water quality of effluent is higher than that of effluent of the conventional filter, and the turbidity of the effluent is less than 4; and when the process is implemented, a small space is occupied, and during use, the process is not limited by environmental conditions.

Description

technical field [0001] The invention relates to a rainwater recovery and utilization system, in particular to a rainwater collection and utilization process. Background technique [0002] At present, rainwater collection and utilization systems in residential quarters, schools, buildings, etc. usually use rainwater collection, sewage interception, regulation and storage, plant soil filter pools or gravel filter pools, disinfection, rainwater collection and utilization processes in clear water pools or use storage tanks, roofs, etc. Afforestation, disinfection, and rainwater collection and utilization processes in clear water pools. These processes are an effective rainwater collection and interception system, but they involve the relationship with landscaping and roads. The width and depth of shallow trenches are often affected by aesthetics and site conditions. Constraints, the burdened drainage area will be limited; the amount of rainwater that can be collected will be red...
