摘　　要：对城市绿化修剪草与污水厂污泥消化联合处理的可行性进行了研究。选择了10%,20%,30%,40%和50%共5个修剪草与污泥的干基投加比例,试验结果表明,随着修剪草投加量的增加污泥消化系统的产气率亦随之增加,当修剪草投加比例为50%时,消化系统产气率可达348L/kg.TS,与不加修剪草相比,产气率增幅达到30%,修剪草与污水厂污泥消化联合处理是可行的。The feasibility of co-digestion of turf cutting litter and sewage sludge was investigated. The cutting litter was mixed with the sewage sludge at the ratio of 10%, 20%, 30%, 40% and 50%, respectively, based on the dry mass. Under thermophilic anaerobic conditions, the gas production rises with the increase of cutting litter ratio. When the cutting litter ratio is 50%, the digestion system produces gas at a rate of 348 L/kg. TS, 30% more than that produced with sewage sludge only. The result shows that codigestion of turf cutting litter and sewage sludge is feasible.
