摘　　要：制革废水中高浓度氨氮严重影响了废水的达标排放,针对制革废水高浓度氨氮问题,首先对脱灰工序采用清洁生产,从源头降低氨氮浓度,或者对脱灰软化废液单独处理,以减少进入综合废水处理系统的氨氮浓度。对于已建有生物处理系统的企业,应增加二级生物膜法脱氮工艺。High concentration of ammonium seriously affects the effluent to meet discharge standard. So clean production should be adopted in deashing process to decrease the concentration of ammonium from the very begining. Treating the softening wastewater in deliming process independently can reduce the concentration of ammonium flowing to comprehensive treatment system. The enterprises, which have already established biological treatment system, must add the technology of biological - membrane denitrification to the original treatment processes.
