Problems solved by technology

[0004] Regarding the screening methods of environmental water and watershed water pollutants, the current research involves few industries, and the method commonly used at present is the layer sieving method. The disadvantage of the layer sieving method is that some important pollutants may be missed during the screening process. The priority control pollutants are not comprehensive enough to fully represent the pollutant status of the entire industry

[0125] List of Priority Control Pollutants for Pesticide Production Enterprises

[0126] According to the priority control pollutant screening process in Example 1, first establish the large list of priority control pollutants of the enterprise, and then assign the chemical substances of the enterprise according to the screening assignment principle, metals and organic substances are carried out according to different assignment principles, After scoring, the screening factors are normalized and sorted to obtain the sorting results of Luba chemical substances. The substances before the sorting test are the priority pollutants controlled by the enterprise. The scoring results are shown in Attached Table 17.

Abstract

The invention belongs to the field of environmental monitoring, in particular to a method for screening emergency pollutant composite indicators of a water pollution source. The method for screening emergency pollutant composite indicators of the water pollution source comprises the following steps of roughing, fine selecting and reexamining. The roughing step comprises building a catalogue library, surveying pollution sources, collecting and clearing up. The finely selecting step comprises building a marking system according to the catalogue library built in a roughing stage, adopting a comprehensive scoring method to screen priority control pollutants, using a qualitation-quantification-datamation scoring system to conduct re-screening and sequencing on a roughing list, sequencing according to pollutant scores, and obtaining priority control pollutants of each pollution source. The reexamining step comprises conducting comprehensive composite examination on each selected priority control pollutant through expert groups composed of technical authority groups in each stage and field. With the adoption of the screening method, shortcomings of a layering screening method are overcome, and meanwhile a method for screening the pollutant composite indicators under an abnormal working condition is provided.

Description

technical field [0001] The invention belongs to the field of environmental monitoring methods, and in particular relates to a comprehensive index screening method for emergency pollutants of water pollution sources. Background technique [0002] With the global awareness of environmental pollution and the development of environmental scientific research and protection technology, many countries have adopted strong pollution prevention and control measures. Due to the many types of toxic pollutants, no matter what the purpose of control is, it is impossible to formulate standards and implement control for each pollutant, but only to select some key pollutants for control. That is to say, it is necessary to determine a screening principle to sort many toxic pollutants, screen out potentially dangerous pollutants, and finally obtain a list. We call the priority toxic pollutants as environmental priority pollutants, or priority control pollutants for short. [0003] There are ...
