摘要
重量法是测定水中悬浮物的国家标准方法,但该方法中未对悬浮物报出结果的有效数字进行规定,导致各环境监测站报出的悬浮物数据有效数字不统一。以重庆市北碚区环境监测站多年来对生活污水和工业废水中以及地面水(含地下水)中的悬浮物分析结果为例,对其进行统计整理,提出了重量法测定水中悬浮物报出结果有效数字的参考标准,对规范悬浮物结果报出具有一定的参考价值。
Gravimetric method is a national standard method for measuring content of suspended solids in water. However,it does not regulate how to determine the significant figure in the result,therefore the significant figures in different environmental monitoring stations were not unified. Based on statistical processing of the data on suspended solids in domestic sewage,industrial wastewater and surface water（ including underground water） of Beipei District,Chongqing,we developed a reference standard to integrate the significant figure in gravimetric method,and it provided a certain reference to regulate the significant figure in the result..
