摘　　要：针对污泥厌氧处理的问题,对污泥浓缩消化一体化反应器进行了开发研究,提出了ICSTD、M ISTD和TISTD 3套反应器,反应器由内外2个反应室组成,采用沼气搅拌或机械搅拌。3套反应器的试验结果表明：在中温条件下,进泥含水率98.3%～99.8%,VS/TS 0.52～0.69时,排泥含水率87.4%～97.3%,VS/TS 0.23～0.51,产气量8.2～76.6 L/d,其浓缩和消化效果优于其他反应器。Aiming at sludge anaerobic treatment,integrated reactors for sludge thickening and digestion were researched,and the ICSTD,MISTD and TISTD three sets reactors were designed.The reactors have two reaction chambers and use the methane or machine for sludge mixing.According to the run result,at the medium temperature,while inlet sludge moisture content is 98.3%～99.8% and VS/TS is 0.52～0.69,the discharged sludge moisture content is 87.4%～97.3% and VS/TS is 0.23～0.51,and the practical biogas yield is 8.2～76.6 L/d.It is shown that the efficiency of concentration and digestion is better than other reactors.
