Abstract

PURPOSE: To improve the operating efficiency of a dehydrator by detecting the flow rate and concentration of the sludge to be press-fed to the dehydrator, and so controlling a sludge press-feed pump that the integrated value of the sludge amount obtained from the above-mentioned result and the preset amount and water content of dehydrated cake is attained.
CONSTITUTION: The flow rate and concentration of the sludge from a pump 2 to be press-fed to a dehydrator 3 are detected by detectors 5 and 7 respectively and are inputted to an arithmetic control unit 8. In the arithmetic control unit 8, the integrated value Q0 of the target sludge flow rate is operated by the formula from the rated dehydrated cake amount W0 of the dehydrator 3 and the target water content K0 of dehydrated cake having beforehand been stored and the mean value D etc. of the sludge concentration obtained from the results of said sludge concentration detection. Thence, signals are outputted to a sequence control unit 9 so as to run the sludge press-feed pump 2 until the above-mentioned integrated value Q0 and the integrated value of the sludge flow rate obtained by integrating the signals from said sludge flow rate detector 5 become equal, whereby the dehydrator 3 is run with good efficiency.
