| 摘 要： | 考虑了系统运行目标的不唯一性(考虑出水浊度、CODMn和费用3个运行目标),根据模糊优化思路,把多目标优化转化为单目标综合优化,利用遗传算法的高效搜索性能,对可控参数进行编码、译码、计算适应值函数,求取满足常规系统出水水质约束的模糊较优控制参数组合(包括7项可变运行参数).优化结果表明不同原水水质条件下均对应有不同的运行条件和参数;混凝剂和预氧化剂种类及投量之间均存在一定的配比关系,合适的配比不但可以提高出水水质还可以减少运行费用.

| Abstract: | Considering the multi-object(including the effluent items(turbidity,CODMn) and the running fee) and effluent restriction, the problem is changed into single-object problem using fuzzy optimization ideas,and punishing function is set to meet to effluent quality restriction.Based on genetic algorithms,the fitting function is coded,un-coded,calculated to choose fuzzy optimization parameters(including 7 items).Optimization results shows that different running parameters are calculated under different raw water quality,with effluent meeting to drinking water quality standard.And a proper dose ratio of coagulant to pre-treatment chemical is needed to improve effluent quality and cut down the running fee. |
