对供排水车间污酸站废水砷含量的测定

Measurement of Arsenic in Wastewater of Waste Acid in Water Supply and Discharge Workshop

供排水车间污酸站处理前的污酸进水砷含量高(砷含量>1000mg/L),处理后的污酸出水含微量砷(砷含量<0.5mg/L),根据分析方法的适用范围,用蒸馏法测污酸进水砷,用原子荧光法测污酸出水砷,以得到准确的数据结果。

Abstract： The arsenic content in wastewater of waste acid before treatment was pretty high （more than 1000mg/ L）. The concentration of arsenic dropped to less than 0. 5mg/L after treatment. The Analytical method was examined according to its scope of application. The distillation method could be employed to test arsenic in the wastewater before treatment. The atomic fluorescence spectrometry method was better to measure the arsenic in the wastewater after treatment.
