PURPOSE: To prevent the precipitation of urinary calculus and the malodor accompanied thereby by electrolyzing treated water after the treatment of excretion to reutilize the same as washing water. CONSTITUTION: The treated water discharged from a toilet bowl 1 is subjected to solid-liquid separation by a filter bed 8 and the separated liquid is sent to a second storage tank 9. Subsequently, the liquid is introduced into an electrolytic cell 11 by a pump 10 to be electrolyzed. The electrolyzed treated water is stored in a water tank 13 as washing water by a conduit 12. A water level detection means is provided to the water tank 13 and the pump 10 is operated when the water level in the water tank 13 lowers to send treated water. The filter bed 8 is packed with particles composed of a porous material. As the porous material, sponge and polymer nonwoven yarn are used. When the purifying efficiency of treated water lowers by operation, sewage is discharged from a drain port 14 and fresh water is supplied to resume use. |
