Problems solved by technology

Because this type of rainwater treatment device treats all the incoming rainwater, it cannot separate the initial rainwater, and the rainwater treatment load is large, and the rainwater treatment effect is poor; in addition, the rainwater is treated first and stored for use, and the water quality will deteriorate. , causing adverse effects on the ecological environment

Abstract

The invention relates to an initial rainwater collection and offline treatment system which comprises a regulation and storage grit basin (1), an offline isolation basin (3) and an enhanced treatment basin (5). The top elevation and the bottom elevation of the regulation and storage grit basin (1) are higher than those of the offline isolation basin (3) respectively, the bottom elevation of the offline isolation basin (3) is higher than the top elevation of the enhanced treatment basin (5), the bottom of the regulation and storage grit basin (1) is provided with a first connecting pipe (2) communicated with the offline isolation basin (3), and the offline isolation basin (3) is communicated with the enhanced treatment basin (5) through a second connecting pipe (4). The initial rainwater collection and offline treatment system has the advantages that off separation of initial rainwater runoff is realized, rainwater is treated in a delayed manner, rainwater treatment load capacity is decreased, rainwater treatment effects are improved, and the rainwater can be recycled.

Description

technical field [0001] The invention belongs to the technical field of rainwater treatment, and in particular relates to an initial rainwater collection and off-line treatment system. Background technique [0002] In recent years, due to the development of urbanization, there are more and more hardened roads and roofs in cities. When heavy rainfall occurs, the rain will wash away the roads and roofs, forming initial rainwater runoff, and the concentration of pollutants in the initial runoff is relatively high. If it is directly discharged into the water body without treatment, it will have a serious impact on the water body. At the same time, rainwater is a precious resource, and direct discharge into rainwater pipes is a great waste of fresh water, and the recycling of rainwater is also a requirement for technological development. [0003] At present, the rainwater treatment device is an instant treatment device, that is, when the rainwater hits, the rainwater will be puri...
