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

Embodiment 1

[0020] 1 rough selection

[0021] Firstly, establish a catalog of pollutants under priority control, and formulate a pollution source investigation plan when establishing the catalog, which mainly includes basic information of the enterprise, basic information of the raw materials of the enterprise's products, waste water treatment and pollutant discharge of the enterprise, etc. In addition to this method, it is also necessary to understand the pollution sources under investigation All aspects of information, including: pollution source production process, raw and auxiliary materials related information, sewage treatment facilities and methods.

[0022] The investigation of pollution sources and the summary of experimental data mainly include the following aspects:

[0023] (1) The production process of the pollution source, including the main reaction and side reaction;

[0024] (2) Physicochemical properties of raw and auxiliary materials and products. For heavy metals, foc...

[0129] List of Priority Control Pollutants for Pesticide Production Enterprises

[0130] 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 ranking results of the chemical substances of the enterprise, and the substances ranked higher 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 method, and particularly relates to a method for screening aggregative indicators of optimal controlling pollutant of water pollution source. The method comprises the following steps of rough screening, fine screening and reviewing, wherein the rough screening step relates to a pollution source sewage treatment processing facility inlet water pollutant list and a pollution source sewage treatment processing facility outlet water pollutant list; the fine screening step is to establish a grading system based on an optimal control pollutant directory library established in the rough screening stage, and screen the optimal controlling pollutant through a composite grade method, and then screen and sequence the rough screening lists again, so as to obtain the optimal controlling pollutant of each pollution source; and the review step is to review the previous sample and review the grading process, and establish an emergency optical controlling pollutant list.

Description

technical field [0001] The invention belongs to the field of environmental monitoring methods, and in particular relates to a method for screening comprehensive indicators of water pollution source optimization and control pollutants. 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. ...
