Abstract

A system for early warning heavy metal pollution risk in water on line comprises an on-line detection device, a data processing device and terminal equipment; the on-line detection device, the data processing device and the terminal equipment are connected through wired or wireless network; the on-line detection device is used for acquiring heavy data concentration data in water quality on line and transmitting the data to the data processing device; the data processing device is used for acquiring water quality average pollution index and deviation coefficient according to the heavy metal concentration data and transmitting an early warning signal to the terminal equipment; and the terminal equipment is used for receiving and displaying data and signals from the data processing device. The system can judge the situation of various heavy metal parameters in the water quality by automatically acquiring monitoring data of a water sample and according to a preset water quality evaluationmodule and an early warning module, can reduce the workload of people, can save time, can avoid frequent early warning caused by the fact that a certain abnormal value reaches to a threshold value through an average index model and is close to the true water sample in the aspect of risk evaluation.

Description

Technical field [0001] The invention relates to the technical field of water pollution, in particular to an online early warning system and method for the risk of heavy metal pollution in water. Background technique [0002] With the rapid development of the global economy and the upgrading of industrialization, humans have an increasing demand for water resources, but at the same time, the pollution of water resources is also becoming more and more serious. Among many water pollutants, heavy metal pollution occupies a considerable proportion. Due to the lack of long-term effective continuous monitoring and risk early warning of heavy metals in water bodies, the frequent occurrence of water pollution accidents caused by the pollution of heavy metals and other toxic substances has posed a direct threat to the safety of drinking water in the basin and social production. Therefore, it is of great significance to develop online monitoring technology for heavy metals in surface water...
