At the fixed time or after according to pre-determined number emission infrared pulse signal, relatively decision means 30 can judge whether mixolimnion or sludge blanket are formed on the height corresponding with introducing hole 202,204,206 and 208 based on the enumeration data corresponding with each light receiving element 241a, 242a, 243a and 244a.
Controller 10 may command display units 40 (for example, LCD device) are to illustrate judged result.For example, display unit 40 can use the GUI method to show the sludge blanket and the mixture layer of the image identical with the inside of dislodger 100 on the interface, makes the user can discern judged result easily.
Specifically, according to the state that can separate sludge blanket and mixture layer based on the enumeration data of the infrared pulse signal that receives at light receiving element 241a, 242a, 243a and 244a place.Display unit 40 can show the state of sludge blanket and potpourri with the color that differs from one another or tone.Therefore, can show the state of sludge blanket and the state of potpourri similarly with virtual condition.
Relatively decision means 30 can judge whether the light intensity of transmission is lower than referenced strength, the light intensity of described transmission is measured with the light receiving element 243a place that introduces the measuring chamber 233 that hole 204 is connected, and introducing hole 204 is corresponding to the altitude information at the sludge blanket of the time point that discharges mud.
When the light intensity of transmission was higher than referenced strength, the current height that can be judged as sludge blanket did not reach the predetermined altitude at the sludge blanket of the time point of discharging mud.
Simultaneously, when the light intensity of transmission was lower than referenced strength, the current height that can be judged as sludge blanket had reached the predetermined altitude (being stored in the memory storage 20) at the sludge blanket of the time point of discharging mud.Therefore, controller 10 can be operated mud suction pump 300, to discharge mud from dislodger 100.
But the cycle repeats aforesaid step.Therefore, but the state in user's Real time identification dislodger 100, and, can be automatically from dislodger 100 discharging mud.
When carrying out described step, expectation extraction tube 212,214,216 and 218, valve 221,222,223 and 224 and/or measuring chamber 231,232,233 and 234 be cleaned.
