【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。更多还原

【Abstract】 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 co-digestion of turf cutting litter and sewage sludge is feasible.更多还原
