Abstract

The invention relates to a pre-warning analytical method of toxic and harmful substances and a system. The method comprises the steps as follows: types and contents of the toxic and harmful substances in an object to be detected are detected, the detection data is recorded; a decision-making unit and evaluation indicators are determined according to the detection data; an analytical model of main ingredients and a fuzzy comprehensive evaluation model are constructed according to the decision-making unit and the evaluation indicators, thereby carrying out analysis and evaluation of the toxic and harmful substances. The method of the invention provides the method basis for the development of the pre-warning system of the toxic and harmful substances for meeting the requirements on the different detection widths and detection precisions, thereby providing the fuzzy evaluation basis for the pre-warning analysis and having high pre-warning analysis efficiency, strong processing capacity of uncertainty of the fuzzy rules, advanced analytical method and accurate result.

Description

technical field [0001] The invention relates to the technical field of environmental engineering, in particular to an early warning analysis method and system for toxic and harmful substances. Background technique [0002] As early as 1990, Austria enacted the Law on Recycling of Lamps and White Goods. Subsequently, Italy, Belgium, Norway, Switzerland, the Netherlands, Sweden and other countries successively introduced laws on electronic waste. In February 2003, the European Union promulgated the "Waste Electrical and Electronic Equipment Directive" (WEEE). In the same year, the European Union issued an amendment to the Directive. In order to further regulate the use of hazardous substances, the European Union promulgated the "Directive on the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment" (RoHS) at the same time as the "Waste Electrical and Electronic Equipment Directive". my country has also promulgated corresponding laws ...
