Abandoning, purifying and storing system for rainwater

Abstract

The invention relates to the technical field of rainwater treatment, and discloses an abandoning, purifying and storing system for rainwater. The abandoning, purifying and storing system comprises a purifying and storing chamber, wherein a shell is arranged in the purifying and storing chamber; the shell is provided with a water inlet port, a water outlet port and an overflow port in sequence from bottom to top; a filtering and storing layer is arranged between the water inlet port and the water outlet port in the shell; the water outlet port is mutually connected with a water discharge pipe outside the purifying and storing chamber. By using the abandoning, purifying and storing system, the abandoning, collection and purification functions of the rainwater are realized at a light-rain time interval; the difference of the water quality of the collected rainwater is reduced; the recovery is facilitated; moreover, at a torrential-rain time interval, water can be quickly discharged.

Description

technical field [0001] The invention relates to the technical field of rainwater treatment, in particular to a rainwater waste flow purification storage system. Background technique [0002] The current urban rainwater drainage system is organized drainage, which not only causes non-point source pollution, but also ignores the utilization of rainwater resources. For the sustainable use of rainwater resources, in the process of urban rainwater discharge, it is necessary to discard the heavily polluted primary rain, and to purify and store the rainwater to a certain extent during the process of transporting the rainwater to the sewage treatment plant. While reducing the water quality and water volume load of the sewage treatment plant, it makes rainwater reuse more convenient. [0003] The purification content of rainwater mainly includes the removal of suspended solids, some organic matter and heavy metals, grease, colloidal particles, etc. At present, the rainwater waste f...

AI Technical Summary

Problems solved by technology

At present, the rainwater waste flow purification and storage device mainly includes the following disadvantages: some rainwater waste flow devices only have the functions of first rain waste flow, collection and storage, but do not have the purification function, and ignore the removal of small particles of impurities, grease and adhesive paper particles in the rainwater, resulting in Harvested rainwater is of poor quality and cannot be reused

Due to the filtering effect of the purification layer, some rainwater purification devices slow down the flow rate of rainwater, resulting in the inability to quickly drain water when heavy rains come, and aggravate urban waterlogging
