摘　　要：垃圾渗滤液污水处理厂(站)的运营中,运维人员对原水碱度的关注较少,以至于硝化的不彻底导致反硝化进程受阻;进而,使渗滤液处理厂(站)总氮和氨氮不能达标排放。总氮和氨氮是渗滤液污水处理厂(站)设计、运营的关键参数,原水碱度是硝化进程的影响因数之一。从反硝化脱氮的原理、渗滤液中碱度的来源及其影响、渗滤液生化处理工艺对碱度的影响、老龄垃圾渗滤液和餐厨废水协同处理对碱度的影响、渗滤液生化脱氮处理中补充碱度的药剂选择等方面进行论述,提出渗滤液污水处理过程中碱度的设计计算,以确保硝化进程的合理进行和反硝化脱氮的高效运转,实现渗滤液污水处理总氮和氨氮的达标排放。In the operation of landfill leachate wastewater treatment plant(station),operation and maintenance personnel pay less attention to the alkalinity of raw water,so that the incomplete nitrification leads to the obstruction of denitrification process;Furthermore,the total nitrogen and ammonia nitrogen of the leachate treatment plant(station)can not be discharged up to the standard.Total nitrogen and ammonia nitrogen are the key parameters in the design and operation of leachate wastewater treatment plant(station),and the alkalinity of raw water is one of the factors affecting the nitrification process.This paper discusses the principle of denitrification and nitrogen removal,the source and influence of alkalinity in leachate,the influence of biochemical treatment process of leachate on alkalinity,the influence of collaborative treatment of old landfill leachate and kitchen wastewater on alkalinity,and the selection of reagents to supplement alkalinity in leachate biochemical nitrogen removal,and puts forward the design requirements of alkalinity in leachate wastewater treatment.In order to ensure the reasonable nitrification process and the efficient operation of denitrification and nitrogen removal,the total nitrogen and ammonia nitrogen of leachate wastewater treatment can be discharged to the standard.
