CIRCULATION TYPE TOILET SYSTEM AND WASTEWATER TREATMENT METHOD FOR CIRCULATION TYPE TOILET
PROBLEM TO BE SOLVED: To provide a circulation type toilet system that can be used even though a lifeline is cut off in the event of a disaster or the like and can manage an electric power required for operating the toilet system only by a small scale of photovoltaic power generation apparatus.SOLUTION: In a circulation type toilet system 10 comprising subjecting sewage discharged from a flush toilet bowl 100 to solid-liquid separation in a solid-liquid separation tank 200 to form a primary treatment water, then subjecting the primary treatment water to soil treatment in a soil treatment tank 600 to thereby re-utilize the treated water in the flush toilet bowl 100, the use of a screw type lifting pump 400 as a wastewater pump for water-feeding the primary treatment water from a primary storage tank 300 to the soil treatment tank 600 reduces a starting current of the wastewater pump to a low level and as a result, an electric power required for operating the toilet system can be managed only by a small scale of photovoltaic power generation apparatus 900.SELECTED DRAWING: Figure 1
【課題】災害時等においてライフラインが断たれたとしても使用することができ、小規模な太陽光発電装置だけで必要な電力をまかなうことができる循環式トイレシステムを提供する。【解決手段】水洗式便器１００から排出された汚水を、固液分離槽２００において固液分離し、一次処理水としたのち、土壌処理槽６００で土壌処理して、水洗式便器１００で再び利用することができるようにした循環式トイレシステム１０において、一次処理水を一次貯留槽３００から土壌処理槽６００に送水するための汚水ポンプを、スクリュー式揚水ポンプ４００としたことにより、汚水ポンプの始動電流を低く抑えて、小規模な太陽光発電装置９００だけで必要な電力をまかなうことができるようにした。【選択図】図１
