城市生活垃圾无害化处理的研究

A STUDY ON THE HARMLESSNESS TREATMENT OF CITY DAILY LIFE RUBBIH.

目的: 研究城市生活垃圾无害化处理问题。方法: 用微生物对100 吨城市生活垃圾进行处理, 第六天使垃圾的温度超过70℃, 且在此温度下保持7天, 然后温度逐渐下降到15天。结果: 处理后在垃圾固有微生物中, 细菌总数、真菌数、产气荚膜杆菌量及粪大肠菌的量分别下降了95.51% 、99.09% 、87.60% 和99.70% 。对金黄色葡萄球菌、大肠杆菌、枯草芽孢杆菌、白色念球菌、乙型肝炎病毒及蛔虫卵的杀灭率分别是99.99% 、100% 、96.67% 、99.91% 、100% 及99.00% 。结论:

Objective:One hundred on city daily life rubbish was treated by microbe.Methods:The temperature of the rubbish exceeded 70℃ on the sixth day and maintained in the following 7 days,and then began to reduce till the fifteenth day.Resulto:Among the inherent microbe in the specimen been treated by microbe,the total number of bacteria,the number of fungi,clostridium perfringens and fecal coliforms reduced 95 51%,99 99%,87 60% and 99 97%,respectively.The disinfecting rate of S.aureus,coliforms group,B.subtilis,C.albicans,Hepatiti B.virus and the roundworm egg was 99 99%,100%,96 67%,99 91%,100% and 99 00%,respectively.Conclution:The results show that the biological treatment of the rubbish has successfully reached the standard of harmlessness.
