危险废物处置中心重金属废水处理研究

Study of heavy metal wastewater treatment for hazardous waste disposal center

危险废物处置中心的废水中含有很多重金属离子,主要成分包括铬、铅、汞、砷等,如果不对这些重金属离子进行及时处理,这些污染物就会对环境产生不利的影响。本文针对某危险废物处置中心重金属废水的特点,采用“调节池+絮凝沉淀+A/O工艺+MBR+NF+RO”工艺开展了对重金属废水的处理试验研究,并验证其处理效果。实践证明这种处理技术在重金属废水处理中有良好的应用前景。

The wastewater of hazardous waste disposal center contains many heavy metal ions,mainly including chromium,lead,mercury,arsenic,etc.If these heavy metal ions are not treated in time,these pollutants will have a bad impact on the environment.According to the characteristics of heavy metal wastewater in a hazardous waste disposal center,the process of"regulating tank+flocculation precipitation+A/O process+MBR+NF+RO"is adopted to carry out the experimental research of heavy metal wastewater treatment and verify the treatment effect.Practice has proven that this treatment technology has good application prospects in the treatment of heavy metal wastewater.
