    • Ultrapure water having a reduced amount of TOC and a low electrical conductivity is produced in correspondence with a variation in water quality of raw water. A first water tank has an anaerobic organic matter treatment chamber and an aerobic organic matter treatment chamber which are communicated with each other at their bottom portions. Activated carbon bags are arranged in upper portions of both the chambers, and Bincho charcoal is stowed in the lower portion of the chambers. With this arrangement, carbon compounds and organic nitrogen compounds in the water to be treated are biologically treated by microbes, thereby reducing the TOC. Furthermore, nitrate nitrogen generated through the organic nitrogen compound treatment process is denitrified by the anaerobic microbe, thereby reducing the electrical conductivity of the water to be treated. Both activated carbon towers perform an advanced treatment on remaining carbon compounds and remaining organic nitrogen compounds in the water to be treated from the aerobic organic matter treatment chamber. A controller controls the rate of circulation of the water to be treated and the rate of stirring of the water to be treated on the basis of a signal from a TOC meter, thereby ensuring the water quality of the water to be treated.
    • 与原水的水质变化相对应地产生具有减少的TOC量和低导电性的超纯水。 第一水箱具有在其底部彼此连通的厌氧有机物处理室和有氧有机物处理室。 活性炭袋布置在两个室的上部,并且Bincho炭被收纳在室的下部。 通过这种布置,待处理的水中的碳化合物和有机氮化合物由微生物进行生物处理,从而减少TOC。 此外,通过有机氮化合物处理过程产生的硝酸盐氮被厌氧微生物反硝化,从而降低待处理水的导电性。 两种活性炭塔对待处理的水中的剩余碳化合物和剩余的有机氮化合物进行高级处理。 控制器基于来自TOC计的信号来控制待处理的水的循环速率和待处理的水的搅拌速率,从而确保待处理的水的水质。

    • A method and apparatus for wastewater treatment is provided which can prevent any decrease in permeation efficiency of a submerged membrane without involving an increase in operating cost and sludge generation, and which can treat high concentration organic wastewater efficiently and without dilution. The wastewater treatment method has the steps of: concentrating domestic sludge by means of a first submerged membrane to produce thick sludge; mixing the thick sludge into a water to be treated, and introducing the water to be treated which is so mixed with the thick sludge into an anaerobic treatment portion for anaerobically treating the same; and introducing the anaerobically treated water from the anaerobic treatment portion into an aerobic treatment portion having a second submerged membrane disposed therein to subject the water to aerobic treatment. The water to be treated undergoes treatment with the thick sludge through which its dissolved oxygen content is reduced to zero and organic substances contained therein are adsorbed by the sludge for subsequent treatment in the anaerobic treatment portion.
    • 提供一种污水处理方法和装置,可以防止浸没膜的渗透效率的任何降低,而不涉及运行成本和污泥产生的增加,并且可以有效且无稀释地处理高浓度有机废水。 废水处理方法的步骤是:通过第一个浸没的膜将家用污泥浓缩,产生浓泥; 将浓泥浆混合到待处理的水中,将与稠泥浆混合的待处理水引入厌氧处理部分进行厌氧处理; 并将厌氧处理部分的厌氧处理水引入到其中设置有第二浸没膜的好氧处理部分中以使水进行好氧处理。 待处理的水用浓泥土进行处理,通过该污泥将其溶解的氧含量降低到零,并且其中所含的有机物质被污泥吸附,以便在厌氧处理部分中进行后续处理。
