Industrial Wastewater Containing Heavy Metal and Arsenic was Treated by Lime-iron Salt Technology 石灰-铁盐法处理含重金属及砷工业废水
The final solution containing arsenic was treated by adding lime and ferric salt, and waste water reached discharge standard. 最后的含砷溶液加入石灰和铁盐加以处理,废水达到了排放标准。
The waste water from waste acid treatment section and every workshop were mixed and treated by first-stage lime milk neutralization, arsenic removal with ferrous sulphate and two-stage lime milk neutralization to reach the effluent standard. 来自污酸处理工序和各车间的污水混合后进行一级石灰乳中和、硫酸亚铁除砷、二级石灰乳中和,实现达标排放。

Arsenic precipitation with lime was greatly influenced by temperature, pH and Ca/ As mole ratio. 石灰沉砷效果受温度、pH和Ca/As摩尔比的影响十分显著。
The main factor affected the equilibrium system of precipitation – dissolution for the arsenic removal through the way of the lime precipitation was the common ion effect and the acid effect. 影响石灰沉淀法除砷过程中的沉淀&溶解平衡的主要因素有同离子效应和酸效应。
