At present, there is no uniform screening method for priority control pollutants. For the control of pollutants in the textile industry, most of the focus is on the content of pollutants in products and their testing methods, and the discharge limits of pollutants in wastewater. For the screening research of priority control pollutants rarely reported

Embodiment Construction
[0036] A method for screening pollutants under priority control in the textile industry, comprising the steps of:
[0037] 1. Define the quantitative analysis method of pollutants and construct the pollutant discharge inventory;
[0038] Clarify the production process and discharge nodes to be accounted for, and make a list of the chemical pollutant discharge according to the production process and discharge nodes.
[0039] The quantitative analysis method of pollutants is based on the control of the quality of heavy metal pollutants. Usually, its relative toxicity is less considered. It is used to characterize the quality of pollutants emitted by a unit of production within a certain period of time and a certain volume of space.
[0040] 2. Define the pollutant toxicity analysis method and build its accounting model:
[0041] 2.1. Using the USEtox model as a database, search for the human toxicity characteristic factors and ecotoxicity characteristic factors corresponding to...

The invention discloses a method for screening pollutants under priority control in the textile industry, which consists of the following four parts: (1) defining a pollutant quantitative analysis method and constructing a pollutant discharge data table; (2) defining a pollutant toxicity analysis method and constructing its Accounting model; (3) Use the Spearman correlation coefficient method to test the consistency of quantitative analysis and toxicity analysis ranking; (4) Use the outlier value test method to further identify the ranking differences of three types of pollutants in a textile industry priority control pollutant screening method. The present invention comprehensively uses quantitative analysis and toxicity analysis methods to sort the environmental load caused by the pollutants produced in the industrial production of products, and uses the Spearman correlation coefficient method and the deviation value method to compare the sorting results, providing a basis for the priority management and control of textile industry pollutants. refer to.
Description
technical field [0001] The invention belongs to the field of pollutant control in the textile industry, and relates to a screening method for priority control pollutants in the textile industry. Background technique [0002] A variety of pollutants are produced in the manufacturing process of the textile industry, including heavy metals, benzene series, nonylphenol and other toxic and harmful pollutants. In addition to directly causing harm to the atmosphere, water bodies, and soil, toxic and harmful pollutants will also accumulate in organisms through the food chain, causing serious impacts on organisms, especially human health. In order to prevent and control the impact of pollution, a large number of experiments have been carried out at home and abroad to study the toxic effects of pollutants, and the priority pollutants have been screened. [0003] At present, the screening methods of priority control pollutants at home and abroad mainly include quantitative analysis an...
