中文摘要：
在选取各项指标的“设定值”基础上，提出了一个适用于多项污染指标的水质评价的幂函数加和型综合指数公式。采用鱼群算法优化公式中的参数，得出优化后适用于多项指标的水质综合评价普适指数公式。公式被应用于多个实例分析计算，并与其它多种评价方法评价结果相比较，结果表明：该公式不受污染物种类和数目多少的限制，计算简便、快速，具有可比性、通用性和实用性。
英文摘要：
By setting up benchmarks for water quality indices, a universal exponential formula with power function for multi-indices of water pollutants was put forword for evaluating water quality. Artificial fish swarm algorithm （AF） was used for optimizing the parameters in the formula, and an optimized universal exponential formula for water quality comprehensive evaluation suited to multi-indices is obtained. Evaluation of water quality of several cases, by using the simplified formula with power function, and comparing with results of other methods, shows that the modified universal formula becomes simple, easy, practical, applicable and free of the confine of kinds and numbers of pollutant.
