Description

Technical Field

[0001] The present invention relates to the technical field of chemical environmental protection, and particularly relates to a rainwater manual-automatic integrated discharge system for chemical enterprises. Background Art

[0002] Chemical enterprises use a wide variety of chemical products, and rainwater often carries away a large amount of pollutants. These pollutants are discharged into the municipal pipe network through rainwater, thus polluting water bodies such as rivers and lakes, resulting in water quality pollution and endangering the ecological environment. At present, most of the existing rainwater discharge systems of chemical enterprises only have the function of valve cut-off, and most of the equipped on-line monitoring devices do not have the function of interlocking valves. When the rainwater exceeds the standard, the valve cannot be cut off in time, resulting in excessive discharge.

[0003] Therefore, how to provide a rainwater manual-automatic integrated discharge system for chemical enterprises that can effectively control the quality of discharged rainwater of chemical enterprises and prevent the backflow of municipal rainwater is an urgent problem to be solved by those skilled in the art.
