Intelligent rainwater and sewage dividing system

Abstract

The invention discloses an intelligent rainwater and sewage dividing system, and belongs to the technical field of environmental protection. Different control parameters can be set according to enterprises of different properties, and therefore rainwater and sewage dividing is achieved precisely. The intelligent rainwater and sewage dividing system comprises a rainwater pipeline of an urban road or an industrial and mining enterprise, namely, a pipeline A, a pipeline B conveying rainwater to rivers and lakes, a pipeline C communicated with a rainwater and sewage separating pool, a control unit and a rainfall information measuring unit. A rainwater and sewage dividing valve is arranged on the pipeline C. In the initial state, the pipeline A is communicated with the pipeline C and is not communicated with the pipeline B. The rainfall information measuring unit monitors whether rainfall occurs or not and the rainfall capacity in real time. After rainfall starts, when the rainfall capacity measured by the rainfall information measuring unit reaches a preset value in the control unit, the rainwater and sewage dividing valve is closed by the control unit, and the pipeline A is communicated with the pipeline B and is not communicated with the pipeline C. When rainfall stops, the rainfall information measuring unit sends a rainfall stop signal to the control unit, the rainwater and sewage dividing valve is opened by the control unit, and the system returns to the initial state.

Description

technical field [0001] The invention relates to a rain-sewage diversion system, in particular to an intelligent rain-sewage diversion system, which belongs to the technical field of environmental protection. Background technique [0002] With the gradual strengthening of pollution control in the country, more and more pollution sources are included in the scope of control. At present, although some urban roads and rainwater pipe networks of industrial and mining enterprises are equipped with rain and sewage diversion devices, they cannot perform precise rain and sewage diversion; the main defects are as follows: [0003] (1) Although there is a "switching diversion" system in the urban rainwater pipe network, it is impossible to accurately judge the amount of rainwater. If there is a long period of light rain, the clean water that could have been directly discharged into the "rivers and lakes" will be mistakenly entered into the sewage pipe network in the later stage.

AI Technical Summary

Problems solved by technology

At present, although some urban roads and rainwater pipe networks of industrial and mining enterprises are equipped with rain and sewage diversion devices, they cannot perform precise rain and sewage diversion; the main defects are as follows:

However: if there is not much rainfall, the rainwater may not be able to wash away the toxic and harmful substances on the ground within the set time period, and the sewage will be discharged into nearby rivers and lakes, causing pollution

In addition, different enterprises (such as chemical, pharmaceutical, printing and dyeing, textile, machinery, clothing, etc.) have great differences in the degree of pollution on the ground of their factory areas, and some pollution sources (factors) between enterprises even differ by dozens of times; Without a unified standard, even if different standards are formulated for different companies, the companies cannot implement them, and the environmental protection department cannot monitor them
