Abstract: The influences of all the factors on the start-up of solidification and nitrification systems and nitrification activity have been researched,on the basis of directional,acclimated,high efficiency and stable nitrification sludge. The results show that when threadlike coconut shell and perlite are used as solid state fermentation substrates,and when the volume ratio of coconut shell and perlite is 1:2 and the water content about 55%,the nitrification activity of nitrifying sludge solid state fermentation inoculant is the highest. Nitrification system in the start-up stage is inoculated with nitrifying inoculant. The start-up time of nitrification system is shortened from 18 days of uninoculated treatment to 14 days. The inoculation of nitrifying inoculant could strengthen the nitrification activity of normally running nitri-fication systems.

摘要： 在定向驯化高效稳定硝化污泥的基础上，研究了各因素对硝化系统启动及硝化活性的影响。结果发现，以丝状椰壳与珍珠岩作为固态发酵的基质时，椰壳与珍珠岩的体积比为1∶2、含水率为55%左右时，硝化污泥固态发酵菌剂的硝化活性最高。硝化系统启动阶段接种硝化菌剂，硝化系统启动时间由未接种处理的18 d缩短到14 d。接种硝化菌剂可强化正常运行硝化系统的硝化活性。
