Abstract

The invention discloses a rainwater channel sewage blocking screen for initial rainwater filtration. The screen comprises a rainwater channel of which the lower portion is communicated with a municipal pipe, a water inlet is formed in the upper end of the rainwater channel, a rainwater strainer is arranged in the water inlet in an erection mode, and the rainwater channel comprises a sundry area which is horizontally divided and communicated with the water inlet and a water purification area which is communicated with a municipal pipe; the sundry area is communicated with the upper end of the rainwater channel; the sundry area and the water purification area are communicated with one or more layers of separation filter screens which downwards incline vertically or toward the sundry area; the rainwater channel sewage blocking screen has the advantages that a filtering structure is automatically cleaned, and the water filtering rate and filtering effect of the filtering structure are guaranteed.

Description

Technical field [0001] The invention relates to the field of rainwater treatment, in particular to a rainwater channel dirt blocking screen used for initial rainwater filtration. Background technique [0002] The development of urbanization in our country has led to an increase in impervious roads in cities, and sudden urban waterlogging caused by storm runoff has become an important reason for cities to "see the sea". With the increase of high-rise buildings in the city, in midsummer, building air-conditioning and automobile exhaust have increased the city's "rain island effect", and rainfall runoff carries a lot of pollutants. However, the existing urban drainage facilities are poorly maintained and managed, and most of the urban drainage network is seriously blocked. To solve the problem of siltation, the source filtration is particularly important; the rainwater channel is the main entrance for roadside drainage, and rainwater grate is generally placed on it for isolation an...
