Efficient pollutant intercepting device for gutter inlet

Abstract

The invention provides an efficient pollutant intercepting device for a gutter inlet. The efficient pollutant intercepting device comprises a box body (7), wherein the upper edge of the box body (7) comprises a retainer which comprises a turnup (8); the box body (7) comprises side surfaces and a bottom surface; the box body (7) also comprises a handle (9); a pollutant intercepting mesh (10) is arranged at the inner side of the box body (7); a filler (5) is loaded between the sides surfaces of the box body (7) and the pollutant intercepting mesh (10). The efficient pollutant intercepting device for the gutter inlet is capable of intercepting pollutants going into the gutter inlet such as leaves, paper scraps and cigarette butts, and preventing the gutter inlet and a pipeline from being blocked; particles in the primary rainfall runoff are removed through a filter material filled in the space reserved at the four sides of the device; when the volume of runoff is large, rainwater is capable of directly going into the bottom space of a gully trap via a filter screen in stead of the filter material layer.

Description

technical field [0001] The invention relates to a sewage intercepting device for a rainwater outlet. Background technique [0002] At present, the phenomenon of garbage deposition in rainwater wells in China is prominent. Before the arrival of the rainy season every year, the municipal departments have to clean up the rainwater outlets, which is time-consuming and laborious, and the cleaning costs are also increasing year by year. [0003] At present, the form of domestic stormwater interception devices is relatively single. On the one hand, in order to ensure the normal water passing capacity of the stormwater outlet, the sewage interception of the stormwater outlet is limited to intercepting large garbage such as leaves, cigarette butts, and stones. The control effect of particulate matter in the relatively seriously polluted initial runoff is not obvious, and pollutants such as N, P, and heavy metals contained in particulate matter continue to enter urban water bodies, re...

Problems solved by technology

[0004] The invention application with the application number 201310189353.6 discloses a sewage intercepting rainwater outlet, such as figure 1 As shown, it includes the stormwater outlet and the rainwater grate installed on the stormwater outlet, and the interception weir is set on the grading section around the stormwater outlet. The device in this application can intercept pollutants directly entering the stormwater outlet, but it is easy to cause road accumulation ; The utility model patent whose application number is 201120491449.4 discloses a kind of anti-odor escaping and preventing foreign matter from falling into the rainwater outlet, such as figure 2 and image 3 As shown, it includes a well wall, a grate, a grate seat, and an isolation cover. The isolation cover is placed on the grate seat below the grate in the rainwater outlet. This device can prevent debris from entering the sewer system, but it cannot control organic matter in rainwater , heavy metals and other small particle pollutants; the Chinese invention application with application number 201210370448.3 discloses a rainwater outlet with peak cutting and pollution removal capabilities, such as Figure 4 As shown, it includes a rain grate covering the drain outlet of the impermeable wall-type well shaft. The drain outlet of the impermeable wall-type well shaft is smaller than the rain grate. But its high cost is not conducive to the cost control of municipal engineering
