摘　　要：采用好氧堆肥方式,研究了味精废液对造纸污泥堆肥的影响,结果表明,以味精废液作为氮源,缩短了造纸污泥堆肥过程达到高温的时间,延长了高温持续时间,加快了堆肥含水量和C/N值的下降,加快了造纸污泥堆肥发酵进程,且味精废液作为氮源的效果优于尿素。Under an aerobic condition,the compost using pulp and paper mill sludges, a biosolid waste, as the basic material was carried out to study the effects of adding monosodium glutamate wastewater. The results showed that,adding monosodium glutamate wastewater as nitrogen resource shorten the time of reaching high temperature, extended high temperature sustaining time, accelerated water content and compost C/N reducing,accelerated the decomposing process. Monosodium glutamate wastewater as nitrogen resource showed better effects on aerobic composting of pulp and paper mill sludges than urea.
