摘要： PROBLEM TO BE SOLVED: To provide a flocculant composition and a flocculation method by which a COD value is lowered and decolorization is carried out for dye wastewater within a short time and in a fewer number of treatment steps.SOLUTION: The flocculant composition includes a component derived from Abelmoschus of Malvaceae, an inorganic flocculant, a pH adjustment agent, activated carbon, and a polymer flocculant. In addition, if necessary, an inorganic adsorption assisting agent such as a zeolite or the like may be added. The order to be added may be properly changed in accordance with the state of the dye wastewater. For example, in a non-threne-based dye wastewater, it is preferable to carry out the treatment by steps of adding the component derived from Abelmoschus of Malvaceae, the flocculant component, the pH adjustment agent, activated carbon, and the polymer flocculant in this order or by steps of adding the component derived from Abelmoschus of Malvaceae, the pH adjustment agent, the flocculant component, activated carbon, and the polymer flocculant in this order. The activated carbon loading may be also properly changed in accordance with the state of the dye wastewater.
摘要翻译：要解决的问题：提供一种絮凝剂组合物和絮凝方法，其中COD值降低并且在短时间内以较少数量的处理步骤对染料废水进行脱色。解决方案：絮凝剂组合物包括衍生自马鞭草科的阿贝氏梭菌的组分，无机絮凝剂，pH调节剂，活性炭和聚合物絮凝剂。此外，如果需要，可以添加无机吸附助剂如沸石等。根据染料废水的状态，可以适当改变添加顺序。例如，在非硫化镉染料废水中，优选通过以下步骤进行处理：将来自马鞭草科的成分，絮凝剂成分，pH调节剂，活性炭，聚合物絮凝剂的成分该顺序或通过以下顺序依次添加源自马鞭草亚科的组分，pH调节剂，絮凝剂组分，活性炭和聚合物絮凝剂。还可以根据染料废水的状态适当地改变活性炭负荷。版权所有（C）2013，JPO＆INPIT
