对高浓度渗滤液进行生化处理具有局限性，尤其对在初期无法完全降解渗滤液中难降解的特殊有机物质，需对菌种污泥进行驯化。该研究基于实际工程案例，总结2个月渗滤液生化处理技术工程中初始调试期的污泥培养技术及其影响因素参数控制。菌种污泥含水量80%左右，采用低负荷培养驯化的模式，按照先好氧后厌氧培养的顺序，驯化初期的原水稀释倍数为10倍，生化内回流比为3，控制生化池碳氮比为5∶1，在污泥培养驯化期间注意调控硝化及反硝化池中的pH、温度、碱度、溶解氧等环境影响参数。经过调试后，生化处理系统出水水质为NH3-N 12～27mg/L、CODcr 58～107mg/L、pH 6.8～8.0，出水水质满足后续MRB工艺要求[1]。

There are limitations in the biochemical treatment of high concentrations leachate. Especially when the biodegradable organic objects in the leachate can not be completely degraded in beginning,So the sludge of bacteria need to be acclimated. The study is based on actual project case. Sludge cultivation techniques and relevant factors in biochemical treatment technology of landfill leachate projects during two months’ debugging step are summed up. The using Sludge which have about 80% water,and choose the low load domestication and cultivation mode.The sludge is cultivated through aerobic digestion before anaer-obic digestion. raw water dilution ratio is controled to 10 times, Internal biochemical reflux reflux ratio is 3,with carbon nitrogen ratio of 5:1,During the cultivating process,denitrification and pH,temperature,al-kalinity, dissolved oxygen and other influencing parameters should be regulated. After debugging, effluent water quality can reach the requirements of subsequent MBR process with NH3-N content of 12~27mg/L, CODcr,58~107mg/L,pH6.8~8.0.
