摘要
采用西华大学内的沱江河水、井水、自来水为样品,通过化学和仪器分析方法对其硬度、高锰酸盐指数(PV)以及有害金属离子铅含量进行检测分析。研究表明:自来水总硬度在国家标准限值内,井水达到了Ⅰ类水标准;自来水的高锰酸盐指数符合国家标准限值,井水属于Ⅰ类地下水,沱江河水属于Ⅰ类地表水域;自来水的含铅量小于国家要求的饮用水限值,井水划归为Ⅰ类地下水域,而沱江河水为Ⅲ类地表水域。
The authors choose the water of Tuojiang,well water and tap water in Xihua University as samples to analyze the hardness,permanganate index（PV）,and the content of plumbum using chemical analysis method and instrument analysis method.The results show that according to the total water hardness of the national standard,the well water reaches the standard of class Ⅰ;the permanganate index of tap water in line is within the national standard limit,while well water belongs to the first class of groundwater,water from Tuojiang belongs to the first class of surface waters;the lead content of tap water is less than the limit value of drinking water according to national requirements.Well water is classified as class Ⅰof groundwater while Tuojiang water is classified as class Ⅲ of surface water.
