A SANITARY DRAIN DISPOSED PROCESS OF SANITARY DRAIN

摘要

PURPOSE: A method for processing sludge of a drudging vehicle of a manhole is provided to enable easy and economic post processing by collecting sludge and reducing weight and moisture content, and to improve workability. CONSTITUTION: A method for processing sludge of a drudging vehicle of a manhole comprises: a step of inputting a suction nozzle which is connected to an inlet of a vacuum pump into the inside of the manhole of a drain, pumping sewage and sludge, and storing in a storage tank; a step of inputting the sewage and sludge into a dehydration device using a transfer pump; and a step of dehydrating the sewage and sludge and minimizing the volume of the sludge. In the collection step, the viscosity of the sludge is reduced by pulverizing and mixing solidified sludge in the manhole by spraying water around the suction nozzle as soon as the sewage and sludge are inhaled through the suction nozzle. In dehydration step, the moisture is separated from the sludge by filtering and the sludge is dehydrated by promoting separation of moisture from the sludge by external pressure applied from the outside.
