WASTE LIQUID TREATING DEVICE

PURPOSE:To make it possible to safely handle a waste liquid contg. harmful materials with good operations and environment by efficiently executing solidification treatment of the waste liquid. CONSTITUTION:A reaction treating vessel 3 having a waste liquid supplying port 1 and a charging port 2 for a powdery solidification treating agent consisting essentially of quicklime is freely rotatably provided with a reaction stirring body 5 consisting of feed vanes 4 which mix and stir the waste liquid and the solidification treatment agent, and transport and gather the mixture to a prescribed position. A bag filter 6 which separates the powder and steam generated by the exothermic reaction of the quicklime is connected to the reaction treating vessel 3. A recovering box 8 having a suction mechanism 7 for sucking and extracting the reaction solids in the reaction treating vessel 3 is communicated and arranged in the reaction treating vessel 3. As a result, the safety of a waste discharging treatment is improved and the solidification treatment to seal in the harmful materials is executed in a short period of time. The good working environment is maintained and the ancillary treating equipment is made compact and simple.
