Gutter inlet suitable for sponge city construction and black and odorous water treatment

Abstract

The invention provides a gutter inlet suitable for sponge city construction and black and odorous water treatment, and relates to the field of environment-friendly gutter inlets. The gutter inlet comprises a primary filtering mechanism, a sewage interception mechanism and a sewage restoration mechanism. The primary filtering mechanism comprises an outer frame and a cover plate arranged on the topof the outer frame, and two sides of the cover plate are placed on the top of the outer frame through anti-skid pads. According to the invention, the primary filtering mechanism, the sewage interception mechanism and the sewage restoration mechanism are arranged, so that rainwater pollutants can be intercepted, filtered, adsorbed and sedimented in sequence, the purification of the initial water quality of the rainwater can be effectively realized, the urban non-point source pollution is controlled, the pollution problem of pollutants to urban water is solved, multiple pollutant intercepting measures are taken, an overflow bin, as well as a first sewage purification bag and a second sewage purification bag which carry out reverse filtering on rainwater are further arranged, and therefore the rainwater purification problem can be efficiently solved, and smooth rainwater drainage can be guaranteed.

Description

technical field [0001] The invention relates to the field of environmental protection gullies, in particular to a gully suitable for sponge city construction and treatment of black and odorous water bodies. Background technique [0002] Due to the continuous deterioration of urban water bodies in recent years, affecting people's life and health, the country has attached great importance to this. Walking along the streets, you can always smell the stench from the rainwater outlet. Generally, it is the smell emitted by roadside restaurants and snack sellers wantonly dumping leftovers and other garbage into rainwater outlets, vehicle exhaust, garbage dropped by vehicles and other pollutants washed into rainwater outlets by rainwater and deposited in road rainwater collection outlets after chemical reactions. These pollutants contain a large amount of organic matter, pathogens, heavy metals, grease, suspended solids and other pollutants, which usually exceed the pollution level ...

AI Technical Summary

Problems solved by technology

These pollutants contain a large amount of organic matter, pathogens, heavy metals, grease, suspended solids and other pollutants, usually exceeding the pollution level of ordinary urban sewage, and are one of the main culprits of rainwater polluting urban water bodies. Discharged into rivers or natural receiving water bodies, it will also cause very serious pollution to urban water bodies, affecting people's life and health

[0003] However, most of the traditional rainwater outlets simply add a layer of sewage interception net, but the rainwater is still discharged directly in this way, the water quality cannot be improved, and the water quality will still be polluted. Some rainwater outlets pass through the rainwater Set up a sedimentation tank near the mouth to solve the pollution problem of the initial rainwater, but the construction process of this method is complicated, the maintenance is also relatively difficult, and the construction is inconvenient. Therefore, the present invention proposes a rainwater mouth suitable for the construction of a sponge city and the treatment of black and odorous water bodies to solve the above-mentioned problems. proposed question
