    • A method and an apparatus for wastewater treatment using a nitrogen/phosphorus removal process combined with a floatation separation of sludge that is replaced by the gravity settling secondary clarifier are provided for effectively removing organic substances, nitrogen, phosphorus, granular substances and the like from wastewater. Al or Fe electrode plate is used for generating the micro bubbles so that phosphorus is removed by Al or Fe ions dissolved from the anode. With the method and the apparatus, a concentration of the microorganisms in the bioreactor is maintained high so that the volume and area of the reactor are reduced, that removal efficiency for organic substances, nitrogen, phosphorus is increased, that deterioration of settlability due to sludge bulking or micro floc and deterioration of out-flowing water quality are prevented, that the time required for settling is reduced to increase the processing quantity of wastewater, and that removal efficiency for phosphorus is maximized by simultaneous performances of biological phosphorus removal and chemical phosphorus removal by chemical agglomeration in the solid-liquid floatation separation vessel.
    • 提供了一种利用氮/磷去除工艺结合浮选分离污泥进行废水处理的方法和装置,该污泥由重力沉淀二次净化器代替,从废水中有效去除有机物,氮,磷,颗粒物等 。 Al或Fe电极板用于产生微气泡,使得通过从阳极溶解的Al或Fe离子除去磷。 利用该方法和装置,生物反应器中微生物的浓度保持较高,使得反应器的体积和面积减小,有机物质,氮,磷的去除效率提高,污泥沉淀的劣化 防止膨胀或微絮凝,流出水质恶化,减少沉淀所需的时间,增加废水的处理量,通过生物除磷和化学除磷同时实现磷的去除效率最大化 通过固体 - 液体浮选分离容器中的化学附聚。

    • An apparatus for a continuous, automated quantitation of tin compounds in liquid samples and a method for quantitative analysis based on the said apparatus are provided herein. The inventive apparatus acidifies liquid samples and in case organotin compounds are present in the sample, a selective UV irradiation converts the organotin compounds into inorganic tin. The inventive apparatus quantitates this inorganic tin by means of electrochemical methods. The apparatus and method of the present invention allow quantitative analyses of trace amounts of organic and inorganic tin compounds present in liquid samples by converting organotin, a form unsuited for measurement, into inorganic tin, a form amenable to measurements and performing electrochemical analysis. Above all, the present invention affords the construction of an automated, continuous analysis system, making unnecessary additional manual operations and reducing labor costs. The present invention also provides an apparatus for converting organotin compounds into inorganic tin.
    • 本文提供了一种用于液体样品中锡化合物的连续自动定量的装置和基于所述装置的定量分析方法。 本发明的装置酸化液体样品,并且在样品中存在有机锡化合物的情况下,选择性UV辐射将有机锡化合物转化为无机锡。 本发明的装置通过电化学方法对该无机锡进行定量。 本发明的装置和方法允许通过将不适于测量的形式的有机锡转化成无机锡(可用于测量和进行电化学分析的形式)来定量分析液体样品中痕量的有机和无机锡化合物。 最重要的是,本发明提供了一种自动连续分析系统的结构,从而进行不必要的附加手动操作并降低人工成本。 本发明还提供了将有机锡化合物转化成无机锡的装置。
