    • PROBLEM TO BE SOLVED: To provide an anaerobic treatment apparatus capable of further efficiently eliminating organic matter from waste water that contains organic matter.SOLUTION: The anaerobic treatment apparatus includes a reaction tank that has granules and obtains anaerobically treated water by anaerobically treating the waste water containing organic matter, with the granules. The apparatus is constituted to discharge the anaerobically treated water to the outside of the reaction tank by allowing the anaerobically treated water to flow out of the water surface side of the reaction tank. The apparatus also includes a concentrated water producing apparatus constituted to put the anaerobically treated water discharged to the outside of the reaction tank, into an airtightly pressurized state to pressurize the granules contained in the anaerobically treated water discharged to the outside of the reaction tank and to obtain separated treated water less in granule content than the anaerobically treated water, and concentrated water more in granule content than the anaerobically treated water, by sedimentation separation from the anaerobically treated water put in the pressurized state. The apparatus is constituted to return the concentrated water to the reaction tank.
    • 要解决的问题:提供一种厌氧处理装置,其能够进一步有效地从含有机物质的废水中去除有机物质。 解决方案:厌氧处理装置包括具有颗粒的反应罐,并通过用颗粒对含有机物的废水进行厌氧处理获得厌氧处理的水。 该装置构成为通过使厌氧处理的水从反应槽的水面侧流出而将厌氧处理的水排出到反应槽的外部。 该设备还包括一种浓缩水生产设备,其将排放到反应罐外部的厌氧处理水放入气密加压状态,对排出到反应罐外部的厌氧处理水中所含的颗粒进行加压, 通过与进入加压状态的厌氧处理水进行沉淀分离,获得颗粒含量比无氧水处理水更少的分离处理水,并且浓缩水的颗粒含量比无氧水处理水更多。 该装置构成为将浓缩水返回到反应罐。 版权所有(C)2013,JPO&INPIT
