【摘要】 采用统计学及质量控制的一些基本理论及方法对污水处理厂的运行数据进行分析,得出城市污水处理厂BOD5、COD、SS、TN、TP等主要出水指标呈正态分布的规律;城市污水BOD5、COD、TN、TP等指标间存在显著线性相关性的结论。研究结论可用于污水处理厂制定经济合理的出水监测方案以及对污水处理厂运行可靠性等进行评估。更多还原

【Abstract】 The running data of some municipal wastewater treatment plants were analyzed by the statistics and quality control theories and methods.The conclusions were drawn for the first time that such indexes as BOD₅,COD,SS,TN and TP of effluent well accord with normal distribution,and the indexes of BOD₅,COD,SS,TN and TP of municipal wastewater have remarkable linear correlation.The result was gained from different wastewater drainage areas.The results are favorable for making economical water quality monitoring project and evaluating the running reliability of wastewater treatment plants.更多还原
