A variable initial rainwater abandonment flow control system, control method and construction method

Abstract

The invention relates to a variable initial rainwater flow abandon control system and control method and a construction method. The control system comprises a meteorology receiving system, a controller and a flow abandon device; the meteorology receiving system transmits a received weather forecast and received real-time meteorology data to the controller; the controller determines a flow abandon time point which meets the requirements of corresponding pollutant concentrations according to the interval day number between this-time rainfall and last-time rainfall, the rainfall intensity acquired by the weather forecast, the pollutant concentration changing conditions in the initial period of the rainfall and the inter-relations among the corresponding pollutant concentrations at t moment in the rainwater runoff process and controls the flow abandon device to stop flow abandon at the flow abandon time point and start collecting rainwater runoff.

Description

technical field [0001] The invention relates to a variable initial rainwater abandonment control system, a control method and a construction method. Background technique [0002] Into the 21st century, with the continuous development of industrial and agricultural society, the problem of water resources has gradually become the main factor restricting the development of human society. [0003] In the early stage of rainfall, the rainwater dissolved a large amount of polluting gases such as acid gas, automobile exhaust, and factory exhaust gas in the air. The pollution level of the sewage is relatively high, even exceeding the pollution level of ordinary urban sewage. This conclusion is called the initial leaching effect. Therefore, in the rainwater collection and utilization, the rainwater abandonment device is generally used to discard the initial rainwater, and the later rainwater enters the water storage facility after simple treatment for utilization. [0004] The exis...

Problems solved by technology

The disadvantage is that the water quality online detection equipment and operating costs are relatively high; the second is that the water quality indicators that can be detected are limited by the detection equipment, and a water quality online detection instrument can only detect a few fixed pollutant indicators. , for other pollutant indicators, it cannot be detected online, and it cannot adapt to the situation that has high requirements for the collected rainwater quality

On the one hand, this method will greatly increase the cost and operating cost of the rainwater collection facilities. On the other hand, there are disadvantages that the electrical components are easily damaged and have a short life, which weakens the stability of the entire rainwater collection facility.

[0010] 3. The general abandonment flow control system cannot reflect the impact of rainfall runoff on water quality from the time of this rainfall, the intensity of rainfall, the duration of rainfall, the time interval between this rainfall and the last rainfall, and cannot determine the amount of collected rainwater. Various more refined water quality indicators

However, the current abandonment devices do not take into account the resource of data obtained by the application of weather stations, and cannot achieve resource sharing.
