摘　　要：针对国内城镇生活垃圾与污水厂污泥处理存在的问题,在污泥浓缩消化理念的基础上,开发了城镇生活垃圾与污水厂污泥一体化处理反应器。反应器由垃圾仓和污泥仓2个部分组成,垃圾仓采用好氧堆肥、污泥仓采用厌氧消化的方式进行,实现了垃圾和污泥在同一个反应器中处理的目标。在垃圾好氧堆肥所产生的热量维持污泥仓32～36℃条件下,反应器运行的效果为:处理污泥20L/d,垃圾15kg/d,进泥含水率为97.2%～99.8%,VS/TS为0.45～0.69时,排泥含水率为92.7%～96.1%,VS/TS为0.28～0.42;垃圾仓进料含水率为73.5%,VS/TS为0.65～0.88时,垃圾出料含水率为48.6%,VS/TS为0.32～0.44。试验结果表明:城镇生活垃圾与污水厂污泥一体化处理反应器作为污泥和垃圾处理设备,对污泥和垃圾的减量及稳定效果良好。Aiming at domestic garbage aerobic compost and town sludge anaerobic treatment, on the basis of reactor TISTD （the integrated of sludge thickening and digestion）which is developed by the authors＇ team, a TIDGTS （the integrated of domestic garbage and town sludge）reactor is designed. The reactor is made up of garbage and sludge chambers. Aerobic compost is adopted in ＂the garbage chamber, while anaerobic fermentation is used in the sludge chamber, thus garbage and sludge can be treated in the same reactor. 32-36 ℃ of sludge digestion can be ensured by the heat from sludge digestion, and 20 L sludge and 15 kg garbage can be treated per day. While inlet sludge moisture content is 97. 2% -99. 8% and VS/TS is 0.45-0.69, the discharged sludge moisture content is 92.7-96.1% and VS/TS is 0.28-0.42garbage moisture content is 48. 6- and VS/TS is 0. 32-0. 44. The results show that the efficiency of concentration and digestion is near to TISTD which is heated by heating wire.
