Problems solved by technology

However, when the distance between the arc-shaped grille bars is too large, the utility model may not be able to realize the function of the overflow grille. If the distance is too small, it cannot be cleaned thoroughly because there is no additional cleaning equipment. When there is a lot of dirt, clogging may occur

Abstract

The invention relates to an initial rainwater overflowing grille with the vacuum suction and slag removal functions. The initial rainwater overflowing grille comprises an overflowing partition wall and a grille net, and further comprises a vacuum suction device, wherein the overflowing partition wall is arranged in a water collection well and partitions a water chamber of the water collection well into a main water chamber and an overflowing water chamber, the grille net is arranged on the top of the overflowing partition wall and used for intercepting particulate pollutants in rainwater, and the vacuum suction device is arranged on the wall of the water collection well and used for sucking and removing residues on the grille net. Compared with the prior art, the vacuum suction device can suck and remove residues on the grille net, and the better ideal residue removal effect can be obtained in a vacuum suction mode.

Description

technical field [0001] The invention relates to a pollution reduction technology in the field of municipal drainage, in particular to an initial rainwater overflow grille with vacuum suction and slag removal function. Background technique [0002] For the urban combined drainage system, the initial rainwater that exceeds the interception capacity of the main drainage pipe is directly discharged into the urban river; for the urban diversion drainage system, the initial rainwater formed by rainfall is also directly discharged into the urban river. Since the initial rainwater carries a large amount of particulate pollutants, when the initial rainwater without any treatment is directly discharged into the urban river, it will cause serious pollution to the water environment quality and ecological environment of the river. At present, for the treatment of initial rainwater pollution, engineering measures such as rainwater storage tanks are often used to intercept and store initia...
