Embodiment 1

[0065] Such as 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 river basin.

[0066] 1. Event background and site survey

[0067] On December 15, 2005, the concentration of cadmium in the Gaoqiao section of the Beijiang River Basin in Guangdong Province was found to seriously exceed the standard, with the highest concentration reaching 0.06mg / L, which is 11% of the standard for Class II and Class III water bodies in the "Environmental Quality Standards for Surface Water (GB3838-2002)". Times, 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 the Beijiang River during the shutdown of the wastewater treatment system at the Shaoguan Smelter in the upper reaches of the Beijiang River.

[0068] The emergency response work immediately organi...

Abstract

The invention discloses an optimal emergency water pollution treatment technology screening method for river basin sudden water pollution accidents and an emergency decision making system. According to the method, firstly, a decision weight calculation method for screening indexes is provided, an evidence theory synthesis rule is applied to introduce an index evidence distance function, n groups of weight scores given by n experts for different screening indexes are synthesized into a group of decision weight scores, and the technical problem of weight conflict between scores of different experts is solved. According to the optimal emergency treatment technology screening method for the basin sudden water pollution accident, the decision weight measuring and calculating method is introduced, and the optimal decision quality is improved. According to the two-stage screening method optimized by the method, the calculation amount can be reduced, and the emergency decision making time canbe saved. According to the emergency decision-making system for the sudden drainage basin water pollution accident, the emergency response is divided into the daily work part and the optimal decision-making part, the emergency response time can be shortened on the premise that subjective opinion conflicts of experts are reduced, and real emergency decision-making is achieved.

Description

technical field [0001] The invention relates to a treatment decision-making method for sudden water pollution accidents, in particular to a method for screening the optimal emergency water pollution treatment technology in the treatment of sudden water pollution accidents in the river basin, which belongs to water environment treatment and water pollution emergency response The field of decision-making technology. Background technique [0002] Watershed sudden water pollution accidents are the most prominent type of sudden environmental accidents. According to statistics, 94.7% of the sudden environmental accidents in our country in recent years belong to the sudden water pollution accidents in the river basin. Sudden water pollution accidents in river basins have the characteristics of sudden occurrence, uncertain scope of pollution, large negative impact, and difficult treatment and disposal. Therefore, emergency response decision-making technology is particularly importa...
