    • The present invention provides a method and a reactor for removing organic matters by immobilized-enzymatic electrode coupled electro-coagulation. In the method, in a single electrochemical system, an enzyme-modified electrode is combined with electro-coagulation to synergistically remove organic matters from water. Certain electrochemical parameters are controlled such that a polymerization reaction is performed between hydrogen peroxide generated by a cathode reaction and organic matters catalyzed by the immobilized-enzymatic electrode. After the polymerization reaction, the organic product enters an anode chamber through a pump. The organic product is precipitated and removed by performing a reaction between the organic product and different hydrolysis products from the electro-coagulation through a coagulating/flocculating effect of compression of a double electric layer, adsorption and electric neutralization as well as precipitation capture. Ultimately, the object of removing the organic matters synergistically through the enzymatic catalyzed polymerization at the cathode and the electro-coagulation at the anode is achieved. The present invention has a strong selectivity for low-concentration toxic organic pollutants and a good effect in removing small-molecular hydrophilic organic matters, the addition amount of enzyme is low, the cathode and the anode are fully used, the cost is reduced, the operation is simple, and the applicable is wide, therefore, the present invention is applicable to a variety of water and wastewater containing organic matters, and the contaminated water.
    • 本发明提供了通过固定化酶电极偶联电凝法除去有机物的方法和反应器。 在该方法中,在单个电化学系统中,将酶修饰的电极与电凝结合以协同地从水中去除有机物质。 控制某些电化学参数,使得在由阴极反应产生的过氧化氢和由固定化酶电极催化的有机物之间进行聚合反应。 在聚合反应之后,有机产物通过泵进入阳极室。 通过双电层压缩,吸附和电中和以及析出捕获的凝结/絮凝效应,通过进行有机产物与不同水解产物之间的反应从电凝中沉淀和除去有机产物。 最终,通过在阴极处的酶催化聚合和阳极处的电凝而协同地去除有机物质的目的。 本发明对低浓度有毒有机污染物具有很强的选择性,对小分子亲水有机物质的去除效果好,酶的添加量低,阴极和阳极得到充分利用,成本降低, 操作简单,适用范围广,因此本发明适用于各种含有有机物的水和废水,以及污染的水。
