Method for screening contaminants to be preferentially monitored in environment water quality of chemical industry park

Abstract

The invention relates to a method for screening contaminants to be preferentially monitored in environment water quality of a chemical industry park, comprising the following steps of: (1) forming an initial list of contaminants to be preferentially monitored in the environment water quality according to a list of liquid contaminants discharged from the chemical industry park and a list of substances detected by a sampling survey of the on-the-spot environment water quality of the chemical industry park; (2) screening out contaminants which are not in the two lists by comparing the initial list with a blacklist of contaminants to be preferentially controlled in water of China and a list of contaminants to be preferentially managed by United States Clean Water Act and forming an preliminary screening list; (3) grading and scoring contaminants by using a multi-parameter comprehensive scoring method, selecting contaminants with a higher comprehensive scoring rank and forming a well-selected list; and (4) further screening out a list of contaminants to be preferentially monitored in the environment water quality of the chemical industry park according to the well-selected list. The method can screen out contaminants to be preferentially monitored in the environment water quality of the chemical industry park in a well-targeted manner, reduce the monitoring cost and improve the monitoring efficiency.

Description

technical field [0001] The invention relates to a method for screening pollutants, in particular to a method for screening pollutants for priority monitoring of environmental water quality in a chemical industry zone, which is mainly used for screening, preferentially monitoring and monitoring toxic and harmful pollutants in the environmental water quality of a chemical industry zone manage. Background technique [0002] With the rapid development of industry, industrial pollution is becoming more and more serious. The sewage discharged from the chemical industry zone has caused serious pollution to the human living environment, especially the harmful substances in the sewage directly threaten human health. Therefore, priority should be given to pollutants with serious hazards. Monitoring is very necessary. [0003] The chemical industry zone is a special type of chemical industrial production site, involving many types of pollutants, and most of them are flammable, explosi...
