摘要
排污河道污染特征模拟分析对防治河道污染与合理开发排污河道具有重要意义。针对当前方法存在河道污染特征模拟能耗高的问题,提出基于模糊综合评价法的排污河道污染特征模拟分析,筛选排污河道污染评价指标,建立污染特征模型,根据排污河道水质指标来分析排污河道上下游浓度之间的关系,获取排污河道水质变化趋势的评价标准,分析排污河道污染特征评价因子的重要程度,得到污染特征的综合评价集,计算加权因子并分析排污河道污染特征的模拟变化趋势,以及排污河道污染特征的模拟能耗,最终实现排污河道污染特征的模拟分析。试验结果表明:提出方法在进行排污河道污染特征模拟分析的过程中,模拟能耗在6J以下,产生了较低的模拟能耗;排污河道污染特征模拟结果与实际结果的拟合度最高为90%,验证了提出方法的有效性和可行性,具有较高的实际应用价值。
The study of simulation and analysis of pollutant discharge channel pollution characteristics has great significance for preventing river pollution and rationally developing river discharge channel.Aiming at the current method exists the problem of high energy consumption of the river pollution characteristic simulation,it is put forward based on fuzzy comprehensive evaluation method of river pollution characteristic simulation analysis,including screening of sewage pollution evaluation index and pollution characteristics of the model is set up,according to the sewage river water quality indicators to analyze the relationship between the sewage concentration of river upstream and downstream,obtain pollution evaluation standard of river water quality change trend,the importance of the analysis of characteristics of sewage river pollution evaluation factor,pollution features a set of comprehensive evaluation,calculate the weighted factor and analysis of the simulation of sewage river pollution characteristics change trend,and the characteristics of sewage river pollution simulation of energy consumption,Finally,the simulation analysis of the pollution characteristics of the discharge channel is realized.The experimental results show that the simulation energy consumption of the proposed method is lower than 6J,and the simulation energy consumption is lower than 6J.The fitting degree between simulation results and actual results of pollutant discharge channel is up to 90%,which verifies the effectiveness and feasibility of the proposed method and has high practical application.
