Plant rainwater monitoring system and rainwater monitoring method

Abstract

The invention discloses a plant rainwater monitoring system and a rainwater monitoring method. A rain gauge is arranged to obtain the rainfall capacity which represent whether there is rainfall or not; a flow meter is used for being started when the rainfall capacity represents that rainfall exists so as to detect the rainwater flow of a rainwater discharge port of the plant area, and the rainwater flow represents whether rainwater flows or not; a control unit is used for controlling the monitoring system to start when the rainfall capacity represents that rainfall exists and the rainwater flow represents that rainwater flows; and the monitoring system is used for performing water quality analysis on the rainwater at the rainwater discharge port when in use. The flow meter is started only when rainfall exists, and the monitoring system is started only when rainfall exists and rainwater flows, omission of analysis of initial rainwater is avoided, accuracy and comprehensiveness are improved, detection reagents can be saved, water quality analysis can be effectively performed on rainwater, energy waste of the monitoring system is avoided, and more energy is saved. The system and the method can be widely applied to the technical field of water quality monitoring.

Description

technical field [0001] The invention relates to the field of water quality monitoring, in particular to a plant area rainwater monitoring system and a rainwater monitoring method. Background technique [0002] Nowadays, the prevention and control of rainwater pollution in industrial plants such as automobile production has always been a subject of great attention. On the one hand, due to the particularity of industrial plants, for example, the leakage of chemical raw materials is prone to occur in the process of production and transportation. After being washed by rainwater, these substances will gather in the rainwater pipe network, which will easily cause the concentration of COD, pH, ammonia nitrogen, SS and other pollutants in the rainwater in the pipe network to exceed the standard. Pollution; on the other hand, there are certain requirements for the prevention and control of rainwater pollution in the factory area of ​​the automobile manufacturing industry. [0003] T...

[0002] Nowadays, the prevention and control of rainwater pollution in industrial plants such as automobile production has always been a subject of great attention. On the one hand, due to the particularity of industrial plants, for example, the leakage of chemical raw materials is prone to occur in the process of production and transportation. After being washed by rainwater, these substances will gather in the rainwater pipe network, which will easily cause the concentration of COD, pH, ammonia nitrogen, SS and other pollutants in the rainwater in the pipe network to exceed the standard. Pollution; on the other hand, there are certain requirements for the prevention and control of rainwater pollution in the factory area of ​​the automobile manufacturing industry

[0003] The existing rainwater pollution prevention and control methods in industrial plants mainly use isochronous automatic sampling to analyze rainwater, but the isochronous sampling method has disadvantages: on the one hand, due to the use of isochronous sampling, it may miss the initial rainwater pollution. On the other hand, if sampling is performed without precipitation, effective sampling and analysis cannot be carried out, which leads to waste of energy for sampling instruments
