Problems solved by technology

This kind of direct drainage system has potential environmental risks. For example, the pollutants in the initial rainwater in the factory area of ​​industrial enterprises mainly come from the erosion of the ground or the top of the building by rainfall, so the sediment on the ground and the top of the building is the main pollution in the initial rainwater. The source of the substance, which generally exists in the form of chemical oxygen demand (COD) in the water quality testing indicators

Embodiment Construction

[0015] Such as figure 1 Shown is the operating environment diagram of the preferred embodiment of the rainwater collection pond control system of the present invention. The rainwater collection tank control system 10 runs in a distributed control system (distributed control system, DCS) 1 (hereinafter referred to as DCS1 ), and the DCS1 includes a display 11 . The DCS1 is connected to a rainwater collection pool 2 through a network, and the rainwater collection pool 2 is arranged on a rainwater drainage pipe network 3 , and rainwater is discharged into the rainwater collection pool 2 from the rainwater drainage pipe network 3 .

[0016] The rainwater collection tank 2 includes a water inlet 20 , an upper outlet 21 and a lower outlet 22 , and the water inlet 20 is connected to the rainwater drainage pipe network 3 . A shut-off gate valve 23 is installed at the lower drain port 22, and the initial state of the shut-off gate valve 23 is a closed state. The cut-off gate valve 23...

Abstract

The invention provides a rainwater collection pool control system. The system runs in a distributed control system. The distributed control system is connected to a rainwater collection pool. The rainwater collection pool control system comprises a control module and a starting module, wherein the control module is used for controlling a chemical oxygen demand analyzer inside the rainwater collection pool to sample rainwater inside the rainwater collection pool, and analyzing a chemical oxygen demand concentration value of the rainwater, the starting module is used for starting a submersible pump inside the rainwater collection pool when the chemical oxygen demand concentration value of the rainwater exceeds the rainwater drainage standard and the liquid level of the rainwater reaches the high liquid level of a liquidometer inside the rainwater collection pool, controlling the submersible pump to pump out the rainwater in the rainwater collection pool, draining the rainwater through an upper water drainage opening of the rainwater collection pool to a wastewater treatment system and closing the submersible pump when the liquid level of the rainwater in the rainwater collection pool reaches the low liquid level set by the liquidometer. The invention further provides a rainwater collection pool control method. According to the rainwater collection pool control system and method, the rainwater can be collected and treated, and environment pollution is prevented.

Description

technical field [0001] The invention relates to a control system and method, in particular to a rainwater collection tank control system and method. Background technique [0002] Generally, industrial enterprises regard the rainwater drainage pipe network in the factory area as an independent drainage system, and the rainwater can be directly discharged to the external environment. This kind of direct drainage system has potential environmental risks. For example, the pollutants in the initial rainwater in the factory area of ​​industrial enterprises mainly come from the erosion of the ground or the top of the building by the rainfall, so the sediment on the ground and the top of the building is the main pollution in the initial rainwater. In the water quality testing indicators, it generally exists in the form of chemical oxygen demand (COD). According to the requirements of environmental risk management and control, the primary rainwater in the factory is defined as waste...
