| Abstract: | 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 re-action 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. |
