| 摘 要： | 通过正交试验研究了用石灰、有机捕集沉淀剂(DTCR)两段法处理高浓度含砷废水的工艺条件，并与常规法比较了处理效果和处理费用。结果表明：用两段法处理后的废水可达标排放；污泥量大大减少，易脱水，含水率低，降低了后处理的难度和费用；污泥稳定，不产生二次污染。该法具有显著的社会效益和生态效益。

| Abstract: | The optimal condition of treatment wastewater containing high-density arsenic by using organic chelating agent with two-stage method was selected with orthogonal design.The comparison of effect and cost of treatment between two-stage method and conventional method was also carried out.The results showed the efficiency of two-stage method treatment is high and the treated wastewater can reach the wastewater discharge standards.Meantime,the amount and moisture of sludge can be decreased,so the post-treatment of waste can be simplified and its charge can also be lowered. |
