WASTEWATER TREATMENT APPARATUS AND WASTEWATER TREATMENT METHOD FOR CONTROLLING FLOW AND THE QUALITY OF WATER AUTOMATICALLY

摘要

The present invention relates to a wastewater treatment apparatus and a wastewater treatment method. The present invention is a buffer storage tank 100 for storing the introduced waste water, the flow rate sensor for detecting the flow rate of the waste water introduced therein; Variable storage tank 110 for storing the waste water in order to receive the waste water of the buffer storage tank 100 or to supply the waste water to the buffer storage tank; A supply pump 106 installed between the buffer storage tank 100 and the variable storage tank 110 to supply wastewater of the buffer storage tank 100 to the variable storage tank 110; A transfer pump 108 installed between the buffer storage tank 100 and the variable storage tank 110 for conveying the wastewater of the variable storage tank 110 to the buffer storage tank 100; A reaction tank 130 for biologically treating the wastewater transferred from the buffer storage tank 100; A sedimentation basin 140 for separating wastewater transported from the reactor 130 into supernatant and sludge; And a control unit 120 for controlling the operation of the supply pump 106 and the transfer pump 108 according to the measured value of the flow sensor, which is to be maintained in the buffer storage tank 100 in the control unit 120. The proper flow rate of the waste water is input and stored, and the control unit 120 operates the supply pump 106 when the flow rate of the waste water measured by the flow sensor installed in the buffer storage tank 100 is higher than the predetermined proper flow rate, and the predetermined titration is performed. If it is lower than the flow rate to operate the conveying pump 108 provides a waste water treatment apparatus characterized in that the automatic control so that the flow rate of the waste water in the buffer storage tank 100 is maintained constant.
