实验室含铅、镉废水的处理方法探究

Lead and Cadmium Freament of Waste Water Exploration

文章报道了利用一种新型的环境矿物材料-羟基磷灰石处理实验室高浓度铅、镉污水的方法,该方法与《环境水质监测质量保证手册》中的消石灰处理法相比具有去除速度快、经济有效、无二次污染、安全环保等显著优点。本文还采用消石灰处理法对一次处理后的废水的上清液进行二次处理,这样能使实验室含高浓度的铅、镉废水,在处理后达到地表水三级质量标准。

This article expounds a laboratory method on how to use hydroxyapatite （Hap） ,a new environment mineral material to extract lead and cadmium, which are in high concentration . ＂The environment water quality monitoring quality assurance manual＂ , This method has obvious advantages, such as： economically effective ,safe and environmental protection ,since there is no secondary pollution ,quick removal speed ,etc. After the lead and cadmium have been removed the water is then treated with calcium hydroxide to bring the water up to the 3rd standard of the surface water in the laboratory.
