Problems solved by technology

[0003] In the current physical and chemical treatment methods, separate coagulation sedimentation or filtration methods are often used for water treatment. Traditional filtration units are prone to clogging, poor media regeneration effect, high self-consumption, large sewage volume, and slow filtration flow rate.
The general water treatment process is equipped with aeration equipment, which increases the operating cost virtually, and the water treatment efficiency is low, and there are few systematic rainwater treatment processes at present.

Abstract

An embodiment of the invention discloses a circular comprehensive rainwater treatment device and method. The device comprises a water distribution unit, a support and a filtering unit, the water distribution unit is connected with a first end of the support, and the filtering unit is connected with a second end of the support. The technical scheme shows that pollutants in rainwater are removed efficiently through the filtering unit; membrane flux of a filtering membrane component is restored through a backwashing device; through a coagulating and precipitating component, the problem that incoming water of a circulating unit contains many impurities is solved, and sludge discharging efficiency of the coagulating and precipitating pool is improved; rainwater after being coagulated and precipitated is delivered into a rainwater tank through the circulating component for cyclic treatment.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a circulating rainwater comprehensive treatment device and treatment method. Background technique [0002] As an easily available fresh water resource, rainwater has been paid more and more attention by people. Developed countries have studied urban rainwater collection and utilization for decades, and my country has also started research in this area in recent years. The collection and utilization of urban rainwater is of great significance. Its significance is mainly reflected in: developing rainwater as a water source and rationally using precious freshwater resources on multiple scales; collecting and using rainwater to solve the problem of urban water accumulation in rainy seasons; Urban microclimate; reduce rainwater discharge, save financial resources and energy for building and maintaining pumping stations. [0003] In the current physical and chemical treatment...
