Abstract

The invention relates to a device and a method for treating sewage wastewater by an autocontrol acoustic method used for reducing sludge water content and improving bypass flow properties, and discloses a device and a method for treating sewage wastewater which are applicable to the reduction of sludge cakes during sewage wastewater treatment and the improvement of bypass flow effects during sludge treatment in water treatment, wherein the automatic measurement corresponds to the sludge viscosity of CST required for reducing sludge water content, or the automatic measurement corresponds to the pH, COD, or viscosity relative to the improvement of bypass flow properties; the acoustic treatment is performed based on the measured values so as to control the water content of the sludge cake, improve bypass flow properties, and thereby increase the operation efficiency of treatment plants.

Description

[0001] Cross reference to related applications [0002] This application claims the rights of Korean Patent Application No. 10-2010-0105629 filed on November 3, 2009 and Korean Patent Application No. 10-2010-0095013 filed on September 30, 2010, with the title "Approved for Automatic control type ultrasonic treatment device and method for reducing the water content of sludge and improving the nature of side flow", their complete contents are incorporated into this application by reference. Technical field [0003] The present invention relates to a device and method for treating sewage and wastewater, in particular to a device and method suitable for improving side flow when treating sewage and wastewater in a water treatment process, wherein the water content of the sludge corresponds to the required CST (capillary The sludge viscosity of suction time) or the pH, COD (chemical oxygen demand) or viscosity related to the improvement of side flow properties are automatically measured,...
