BUILDING WASTEWATER RECLAMATION AND REUSING SYSTEM IN WHICH HIGH EFFICIENT CONTACT OXIDATION TANK WITH FIXED FILTER MEDIUM IS INSTALLED IN FRONT OF FLOW EQUALIZATION TANK, AND MICROBIAL CULTURE MEDIUM IS ADDITIONALLY INSTALLED

摘要

PURPOSE: To provide an economic and stable building wastewater reclamation and reusing system capable of producing good quality wastewater for reusing by maintaining concentration and activity of microorganisms and performing membrane filtration and disinfection processes after removing overflown microorganisms, solids, biological metabolites and phosphorus through a coagulation process. CONSTITUTION: The building wastewater reclamation and reusing system is characterized in that wastewater for reusing is produced by installing a high efficient contact oxidation tank(12') with fixed filter medium(11') in front of a flow equalization tank(2') and installing a microbial culture medium(13'), thereby maintaining concentration and activity of microorganisms and passing wastewater through a membrane(6') and a disinfection tank(8') after removing overflown microorganisms, solids, biological metabolites and phosphorus from waste water through a coagulation process, wherein the microbial culture medium comprises a culture tank in which microorganisms are cultured; a supply part comprising a supply pipe connected to an upper part of the culture tank and a pump installed on the supply pipe to supply a culture media into the culture tank, wherein solution and organic and inorganic culture mediums to be cultured are supplied into the culture tank; an agitation part for ejecting the culture media into the culture tank and agitating the culture media by receiving air from an air supply blower; and a temperature control part comprising a heater installed in the culture tank and a control means for controlling operation of the heater to maintain temperature of the culture media and sterilize the culture media.
