PURPOSE:To obtain a high efficiency of treatment without increasing the revolving number of impellers even if apparatus is enlarged by providing a plural number of impellers whose peripheries have a number of tub-like liquid receivers to the rotary shaft of drum. CONSTITUTION:The horizontal drum 29 with the filtrate inlet 30, the filtrate outlet 31, and the odorous vapor outlet 58 is fixed inside the cylindrical concentrator case 28 with the waste gas inlet 47 and the waste gas outlet 51, and the liquid face 42 of night soil, etc., is formed on the inside circumference of the drum 29 by means of the rotary impeller 77 while utilizing the heat of waste gas for concentration. A number of the tub-like liquid receivers 80 are fitted to the peripheries of the plural impellers 78 having an outside diameter slightly smaller than the inside diameter of the drum 29 and the plural impellers 7a are mounted to the rotary shaft 34 of the drum 29 at intervals. Thus, even if the diameter of the drum 29 is made larger, the liquid face 42 can be uniformly formed without rising the revolving number of the impellers 78, permitting a higher efficiency of treatment. |
