Embodiment 1

[0065] like figure 1 As shown, the method of the present invention is used to screen the optimal treatment technology for a sudden water pollution event in a certain watershed.

[0066] 1. Event background and site survey

[0067] On December 15, 2005, the Gaoqiao section of Beijiang River Basin in Guangdong Province found that the concentration of cadmium exceeded the standard seriously, and the highest concentration reached 0.06mg / L, which is 11 of the "Environmental Quality Standard for Surface Water (GB3838-2002)" Class II and Class III water standards. times, it is a sudden water pollution incident. The investigation found that the source of the pollution was the illegal discharge of a large amount of high-concentration cadmium-containing wastewater into Beijiang by the Shaoguan Smelter in the upper reaches of the Beijiang River during the shutdown and maintenance of the wastewater treatment system.

[0068] Emergency response work immediately organized on-site surveys ...

Abstract

The invention discloses an optimal emergency water pollution treatment technology screening method and an emergency decision-making system for a sudden water pollution accident in a river basin. The present invention first provides a method for calculating decision weights for screening indicators, using evidence theory synthesis rules to introduce a distance function between indicators and evidence, and synthesizing n groups of weight scores given by n experts for different screening indicators into a set of decision weight scores, so as to solve the problem of different experts Technical issues with weight conflicts between ratings. The optimal emergency treatment technology screening method for sudden water pollution accidents in the basin of the present invention improves the optimal decision-making quality by introducing the above-mentioned decision-weight calculation method. The optimized two-stage screening method can reduce the computational complexity and save the time for emergency decision-making. The emergency decision-making system for sudden river basin water pollution accidents of the present invention divides emergency response into two parts: daily work and optimal decision-making, which can reduce the emergency response time on the premise of reducing the conflict of subjective opinions of experts, and realize emergency decision-making in the true sense. .

Description

technical field [0001] The invention relates to a decision-making method for the treatment of a sudden water pollution accident, in particular to a method for screening the optimal emergency water pollution treatment technology for the treatment of a sudden water pollution accident in a river basin, belonging to water environment treatment and water pollution emergency response decision-making technology. Background technique [0002] The sudden water pollution accident in the river basin is the most prominent type of sudden environmental accident. According to statistics, 94.7% of sudden environmental accidents in my country in recent years belong to sudden water pollution accidents in river basins. The sudden water pollution accident in the river basin has the characteristics of sudden occurrence, uncertain pollution scope, large negative impact, and difficult treatment and disposal. Among them, the rapid selection of the optimal processing technology is the core link of...
