Built-in environment-friendly rainwater filtering structure

Abstract

The invention relates to the technical field of rainwater treatment, in particular to a built-in environment-friendly rainwater filtering structure. The built-in environment-friendly rainwater filtering structure comprises a rainwater collecting device, a sewage intercepting basket device arranged below the rainwater collecting device, and a filtering overflow device arranged below the sewage intercepting basket device; the rainwater collecting device is used for collecting rainwater; the sewage intercepting basket device comprises a hollow first support and a first filtering part arranged atthe top or the bottom of the first support, and the first filtering part is used for filtering the rainwater flowing out from the rainwater collecting device; and the filtering overflow device comprises a hollow second support and a second filtering part arranged at the top or the bottom of the second support, the second filtering part is located below the first filtering part correspondingly, andthe second filtering part is used for filtering and draining the rainwater flowing out from the first filtering part. According to the built-in environment-friendly rainwater filtering structure, therainwater can be secondarily filtered, thus pollution is reduced, the water can further be effectively drained, and the possibility of waterlogging is lowered.

Description

technical field [0001] The invention relates to the technical field of rainwater treatment, in particular to an embedded environment-friendly rainwater filtering structure. Background technique [0002] At present, most urban roads generally adopt a more traditional drainage method, that is, rainwater grates are used for drainage, and surface leaves, garbage, etc. flow directly into the urban drainage pipe network through the rainwater grates. The traditional drainage method has the following disadvantages: surface leaves, garbage, etc. flow directly into the urban drainage pipe network through the rainwater grate. This part of garbage often causes the urban drainage pipe network to be blocked, and it is easy to cause urban waterlogging when the amount of rainwater is relatively large. At the same time, the asphalt and cement pavement of the motorway are often affected by the oil pollution and exhaust gas of the passing vehicles. In the early stage of rainfall, the initial r...

Problems solved by technology

The current national standard atlas method has the following disadvantages: the current national standard atlas method is more suitable for new roads, but the rainwater wells on existing roads do not meet the requirements of the national standard, so they need to be demolished and rebuilt, which consumes manpower and material resources; in addition, using The sand-free concrete permeable wall with a long service life is easily blocked by dust, garbage and other dirt, which greatly reduces its water permeability and is easy to cause blockage, and it is difficult to clean or replace the sand-free concrete permeable wall
