摘要： PROBLEM TO BE SOLVED: To quickly and easily reduce the load on a wastewater treatment facility when the organic substance concentration increases in a short time in raw water flowing into the wastewater treatment facility. SOLUTION: The organic wastewater treatment facility includes a former stage solid-liquid separation device for separating solids from the raw water, a biological treatment tank for decomposing with activated sludge an organic substance in the water separated in the former stage solid-liquid separation device, and a latter stage solid-liquid separation device for separating the biologically treated liquid obtained in the biological treatment tank into sludge and treated liquid. When the organic substance concentration is over a prescribed value in the raw water, part of the excess sludge obtained in the latter stage solid-liquid separation device is mixed with the raw water before the inlet port of the former stage solid-liquid separation device. The soluble organic substance in the raw water is adsorbed and/or biologically decomposed by the mixed excess sludge. COPYRIGHT: (C)2011,JPO&INPIT
摘要翻译：要解决的问题：当有机物质浓度在短时间内流入废水处理设备的原水中时，能够快速轻松地减少废水处理设备的负荷。
解决方案：有机废水处理设备包括用于从原水中分离固体的前一级固液分离装置，用活性污泥分解的生物处理罐，在前一阶段固液分离的水中的有机物质分离装置和用于将生物处理槽中获得的生物处理液分离成污泥和处理液的后级固液分离装置。当原水中的有机物质浓度超过规定值时，将后级固液分离装置中得到的多余污泥的一部分与前级固液分离装置的入口前的原水混合。原水中的可溶性有机物质被混合的过剩污泥吸附和/或生物分解。版权所有（C）2011，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a method of operating an organic waste water treatment facility, capable of suppressing sludge outflow from a final sedimentation tank when raw water flowing into the waste water treatment facility rapidly increases in a short time. SOLUTION: The organic waste water treatment facility includes an initial sedimentation tank for settling and removing solid matters in the raw water, an aerobic biological treatment tank for decomposing organic matters in supernatant water in the initial sedimentation tank by activated sludge and the final sedimentation tank for settling and removing sludge from the supernatant water in the biological treatment tank, wherein in the case that the flow rate of the raw water exceeds a prescribed flow rate, the aeration amount of the biological treatment tank is made smaller than a prescribed amount and the amount of the sludge flowing out from the final sedimentation tank is reduced.
