【摘要】 针对垃圾含水量较高对焚烧技术的制约问题,研究采用微生物接种加速垃圾脱水的方法.分别从腐熟矿化垃圾、白菜软腐组织、风干牛粪中分离筛选出4个实验菌株M1、CX1、GX1、RX1,实验菌株两两共存,两两接种发酵最佳组合比例分别为:M1∶GX1为1∶1,M1∶CX为2∶1,M1∶RX1为1∶1.将4株菌M1、GX1、RX1、CX1按照2∶2∶2∶1的比例接入具有明显的优势性,脱水效果高于单菌及两菌组合接种发酵实验组.采用正交实验对组合菌比例进行优化,得到M1、GX1、RX1、CX1比例为2.5∶2.5∶2.5∶1时垃圾减重比率最高.以最佳比例按照0.4%的接种量进行接种,可实现61.63%的较高垃圾脱水率,能够保证实际扩大应用的可行性.更多还原

【Abstract】 According to the problem about solid waste incineration caused by the high water content,a method of accelerating garbage dehydration by vaccinating microorganism was provided in this experimental research.A set of multiple strains: M1,CX1,GX1,RX1 were selected from the mineralized rubbish,rotten Chinese cabbage,and air dried cow muck respectively,and physiological and biochemical experiment were done to test these strains.The results showed that every isolated strain can coexist with another.The combination of the four strains through vaccination with the ratio of 2∶2∶2∶1,has obvious advantage over any single strain or the combination of any two of them.Orthogonal experiments were conduct to obtain the optimized proportion of bacteria combination,which was 2.5∶2.5∶2.5∶1 of M1,GX1,RX1 and CX1.With the best proportion and 0.4% of inoculation,a higher garbage dehydration rate of 61.63% could be realized,which can ensure the feasibility of a large scale application of the method.更多还原
