乌兰察布市污水处理厂水质检测及分析

Water Quality Detection and Analysis of Ulanqab Sewage Treatment Plant

污水处理厂处理污水的能力直接决定一个地方的环境质量,并直接影响着人们的健康。因此,对于经污水处理厂处理过的污水进行水质检测及分析变得尤为重要。本文分别采用重铬酸钾法、玻璃电极法、纳氏试剂分光光度法、二苯碳酰二肼分光光度法、冷原子吸收法对乌兰察布市周边A、B、C三座污水处理厂进出口水样的COD、pH、氨氮、Cr6+、Hg进行了检测。通过对检测结果进行分析,对比城镇污水处理厂污染物排放标准,得出乌兰察布市上述污水处理厂污水均符合该排放标准。

The ability of sewage treatment plants to treat sewage directly determines the environmental quality of a place and directly affects people's health.Therefore,it becomes particularly important to carry out water quality detection and analysis on the sewage treated by the sewage treatment plant.In this paper,the COD,pH,ammonia nitrogen,Cr6+and Hg of water samples from three sewage treatment plants A,B and C around Ulanqab city were detected by potassium dichromate method,glass electrode method,Nannenberg reagent spectrophotometry,diphenylcarbonyl hydrazine spectrophotometry and cold atomic absorption method respectively.By analyzing the test results and comparing the discharge standards of urban sewage treatment plants,it is concluded that the wastewater of the above sewage treatment plants in Ulanqab meets the discharge standards of urban sewage treatment plants.
