Title:
CONTINUOUS BIOLOGICAL WATER TREATMENT SYSTEM USING AN AUTOMATIC WATER QUALITY MEASURING DEVICE FOR OPTIMIZING RESIDENCE TIME
Document Type and Number:
WIPO Patent Application WO/2013/085359
Kind Code:
A1
Abstract:
The present invention relates to a continuous biological water treatment system using an automatic water quality measuring device for optimizing residence time. More particularly, the present invention relates to a continuous biological water treatment system which, in order to improve the treatment efficiency of a continuous biological water treatment process, specifically an anaerobic-anoxic-oxic (A2O) process, and ensure the stability of the quality of treated water by improving biological treatment processes for sewage and wastewater in a movable high-level sewage treatment system having a movable partition wall that moves by means of displacement means, uses an automatic water quality measuring device for measuring the TN concentration of the water discharged from a reaction tank including an aerobic tank, compares the TN concentration measured by the automatic water quality measuring device with a prestored reference TN concentration with a view to moving the movable partition wall so as to increase or decrease the residence time in the aerobic tank and thus set an optimum residence time in the aerobic tank and reduce the cost of power for aeration. The continuous biological water treatment system using an automatic water quality measuring device for optimizing residence time according to the present invention has the reaction tank that includes the aerobic tank, wherein the internal space of the reaction tank is divided by the movable partition wall, configured such that the movable partition wall moves by means of the displacement means, the automatic water quality measuring device for measuring the TN concentration of the water discharged from the reaction tank is provided, and the control unit is provided so as to compare the TN concentration measured by the automatic water quality measuring device with the prestored reference TN concentration, moves the variable partition wall by means of the displacement means so as to increase the space of the aerobic tank in the event the measured TN concentration is greater than the reference TN concentration, and moves the variable partition wall by means of the displacement means so as to decrease the space of the aerobic tank in the event the measured TN concentration is lower than the reference TN concentration, in order to increase or decrease the residence time in the aerobic tank.
