| 摘 要： | 为了明确污水的重点污染物,使污水的特性评价结果更合理、更具实用性,采用水质矩阵与权重分析相结合的评价方法,对西安市城市污水中多种污染物的监测结果进行了分析。结果表明,西安市污水中SS,COD, BOD5,TN和TP的权重分别为0．266 7,0．074 8,0．141 2,0．042 0和0．475 3,溶解态与悬浮态污染物的权重分别为0．637 3和0．362 7。说明该污水中的含磷污染物、有机物和悬浮态污染物对环境及水体的危害较大,应作为污水处理的主要去除目标。

| Abstract: | In order to identify the main pollutant in wastewater, and make the evaluation of wastewater characteristic more reasonable and available, methods of water quality matrix and weight analyzing were used to analyze the results of water quality of Xi'an municipal wastewater in this study. The results show that respective weights of SS,COD,BOD5 ,TN,TP are 0. 266 7,0. 074 8,0. 141 2,0. 042 0,0. 475 3 and respective weights of suspended mater and soluble mater are 0. 637 3,0. 362 7. Therefore it can be concluded that contaminations of suspended matter, organic matter and phosphate in Xi'an municipal wastewater are more harmful to environment and natural water and should be firstly removed in wastewater treatment. |
