<p>PROBLEM TO BE SOLVED: To provide a waste water treatment system and a waste water treatment method which allows the waste water treatment capacity to be satisfactorily maintained even in a place limited in electric power and wafer supply, etc., and is improved so as to reduce solid material, etc., of sludge in sewage. SOLUTION: A circulation system of the sewage is composed of a sludge reducing tank 11 which is internally provided with a bio stone module(BSM), is communicated with a sludge reducing blower 6 and is communicated with a winter season human waste tank 2C via a human waste charging pipe 2E and a septic tank 12 which is communicated with a sludge reducing tank 11 via a transfer pipe 11C for reducing sludge and a discharge pipe 11B and is communicated with a septic tank (aeration) blower 5. A treated water circulating system for sewage and rain water is composed of a rain water collecting tank 14 which supplies rain water stored by a rain water collector 3 which collects rain water to a sewage collecting part and a treated water circulating tank 13 which is communicated with the septic tank 12 via a discharge pipe 12E and is communicated with the rain water collecting tank 14 via a treated water or rain water utilizing and transferring circulation pump 7. This waste water treatment system is further provided with a power generation control system 4 which supplies electric power to the septic tank (aeration) blower 5, the sludge reducing blower 6, the treated water transferring circulation pump 7 and an indoor feeding water circulation pump 8, etc.</p> |
