摘　　要：在总结重金属废水特点的基础上,针对重金属废水氨氮高、去除难的特点,综合大量的研究及工程实践经验,基于传统的硝化反硝化工艺,提出了重金属废水经过分类预处理后,在不同进水浓度的氨氮和硝酸盐氮条件下硝化过程和反硝化过程的关键设计参数,并分析其影响因素,提出相应的工程技术措施。最后,结合工程实践案例,分析重金属废水生物处理的关键设计参数。Based on the summary of the characteristics of heavy metal wastewater,the article focused on the high concentration of ammonia nitrogen and the difficulty in its removal.Integrating a multitude of research and engineering practice experiences,and based on the traditional nitrification-denitrification process,it proposes key design parameters for the nitrification and denitrification processes under different influent concentrations of ammonia nitrogen and nitrate nitrogen after classified pretreatment of heavy metal wastewater.The article analyzes the influencing factors and suggests corresponding engineering technical measures.Finally,by combining practical engineering cases,the key design parameters for the biological treatment of heavy metal wastewater are analyzed,providing a reference for the biological treatment of heavy metal wastewater.
