摘要
基于1995-2004年长江水质的主要统计数据,对长江流域主要地区水质进行评价,根据污染物在水中的降解方程,利用最大差值法确定污染源主要分布地区。利用回归分析方法,建立各类水污染度与时间的回归模型,预测未来十年所有站点总体排污量和各类水质分布。以各站点处理污水之和最小为目标态,不可饮用水比例占长江总长20%以内且没有劣Ⅴ类水为约束条件,经最优化处理得出每年需要处理的污水量。
Based on the data of the Yangtse River water quality during 1995 -2004, we make an assessment on the water quality of the main areas along the Yangtse River. Afterward, we use the maximal difference to confirm the source of pollution through the decomposability equation. Then, we developed the model of the pollution and years by the recursion analysis method, and then we predicted the total discharge capacity. To control the insalubrious water＇s proportion within 20% and to ensure there＇s no inferior quality of V - type water, we made use of the minimum of the sum of disposal suUage from each city to find the quantity of pollution we need to treat with per annum by optimization method.
