PURPOSE: A method for collecting waste water heat in sludge supernatant waste heat and sludge waste heat is provided to improve an energy utilization ratio, and to the reduce the amount of solids. CONSTITUTION: A method for collecting waste water heat in sludge supernatant waste heat and sludge waste heat comprises the following steps of: forming a separate flow path; collecting the heat with a waste heat collector(105); absorbing the waste heat in a first evaporator(501); and transferring the heated water from a first heat exchanger(108) to a warm water reservoir(110). The water is continuously stored by forming a circulation cycle of the warm water reservoir and a condensing heat exchanger. |
