| description | PROBLEM TO BE SOLVED: To provide a waste liquid treatment device for preventing the neglect of filter unit replacement.SOLUTION: The waste liquid treatment device includes: a waste liquid tank 4; a feeding pump 6 that supplies a processing waste liquid stored in the waste liquid tank 4; a filtering means 44 that filters the processing waste liquid; and a clear water outlet 40 that discharges clear water produced by the filtering means 44. The filtering means 44 is equipped with the first and second filter units 8a and 8b each disposed detachably; a switching means 46 that selectively switches an arrival point of the processing waste liquid between a first filter unit 8a and a second filter unit 8b; a control means 56 that includes a first pressure detecting means 48a and a second pressure detecting means 48b and has a determining means 58 determine the clogging of each of the filter units when the pressure detected the pressure detecting means 48a and 48b exceeds a predetermined value; a warning means 62; and a new filter unit detecting means 60 that detects each filter unit to be new after the filter units 8a and 8b are replaced with new ones. |
