<p>PROBLEM TO BE SOLVED: To provide a device for treating drainage wherein the attachability of a heat insulator for a heater, a sound insulator, or the like, can be improved and number of parts can be reduced. SOLUTION: This device is composed of components housed in a casing 90, the components including a tank (a treatment tank 20) wherein the heater 23 fitted on the outside of the sidewall thereof is covered with the heat insulator 24. The tank (the treatment tank 20) to which the heater 23 is fitted is provided with a holding space (a recess 25 and a box-shaped rib 26) to hold the heater 23 and the heat insulator 24 on the outside of its sidewall and the opening of the holding space is covered with the casing 90.</p> |
