METHOD OF TREATING DOMESTIC MISCELLANEOUS WASTE WATER AND MISCELLANEOUS WASTE WATER CATCH BASIN

摘要

PURPOSE: To reduce installation area by drawing off drain water from a bathtub and a washing machine after solid-liquid separation and detention in catch basin and by giving an anaerobic treatment in a catch basin for kitchen drain, filtering its supernatant liquid and providing confluence with bath and washing drain. CONSTITUTION: Kitchen drain A is sent little by little intermittently from kitchen drain inflow pipe 13 to a first chamber 4, and solids are filtered and removed. Next, it is confined for about 1.5 day in the first chamber 4 and a second chamber 5 for anaerobic treatment and sludge is settled and removed thereby creating treated water B and its advection occurs from a supernatant liquid advection pipe 12 to a second chamber 7. Also, drain from bath and washing C is sent intermittently in large quantities from bath, washing drain inflow pipe 14 to a third chamber 6, and solids are removed. Next, it is confined for several hours in a second zone 3 and is discharged as draw-off water D from a draw-off pipe 15 while settling the SS content.
