Embodiment 1

[0059] Such as figure 1 As shown, the method of the present invention is used to identify the optimal treatment technology for a sudden water pollution event in a river basin.

[0060] 1. Event background and site survey

[0061] On January 7, 2009, the concentration of arsenic in the Picang Floodway in Linyi, Shandong Province was found to be seriously exceeding the standard. Sudden water pollution incidents. The investigation found that the accident was caused by Shandong Hongri Akang Chemical Co., Ltd.’s illegal discharge of the tail gas cycle washing water of the phosphoric acid production line into the Picang flood diversion.

[0062] The emergency response work immediately organized a site survey to obtain site survey data. The field survey data obtained include that the water temperature in the basin is about 3°C ​​to 5°C, and the flow rate in the basin is about 180m 3 / s (the flow rate of the water body is about 2m / s), the pH of the watershed is about 7.2-7.8, and t...

Abstract

The invention discloses an emergency treatment technology identification method for sudden watershed water pollution accidents and an emergency decision-making system. According to the method, firstly, a decision weight calculation method for identifying indexes is provided, an evidence theory synthesis rule is applied to introduce similarity coefficients among index evidences, n groups of weightscores given by n experts for different identifying indexes are fused into one group of decision weight scores, and the technical problem of weight conflicts among different expert scores is solved. According to the emergency treatment technology identification method for the sudden drainage basin water pollution accident, the decision weight calculation method is introduced, and the optimal decision quality is improved. According to the two-stage identification method optimized by the method, the calculation amount can be reduced, and the emergency decision making time can be saved. Accordingto 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 an emergency response decision-making method for sudden water pollution accidents, in particular to a method for identifying the optimal emergency water pollution treatment technology for sudden river basin water pollution accidents, which belongs to water environment management and water pollution emergency response Responsive decision-making technology domain. Background technique [0002] Sudden water pollution accidents in river basins are mainly caused by pollutants entering water bodies through human production activities and corporate sewage discharges. They 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 negati...
