摘要
提出了氧化絮凝复合床水处理新技术.由复合床内的两个主电极之间充填高效、无毒而廉价的颗粒状专用材料、催化剂(或催化手段)及一些辅助剂构成.在一定的物理化学操作条件下,废水中的污染物会发生如催化氧化分解、混凝、吸咐、络合、置换等作用而迅速被去除.以含苯酚和三氯乙醛模拟废水为研究对象,研究了这种水处理新技术去除废水中有机物的机理,主要是基于生成H2O2并迅速产生羟基自由基对水中有机物的强氧化作用.用自旋捕集ESR法测出了在复合床处理废水过程中不断产生的·OH.最后对城市生活污水、印染和医药等实际工业废水进行了处理试验。
The new oxideflocculation reactor (OFR) technique for wastewater treatment was successfully developed. The OFR is filled with the high effect nontoxic special material, catalyst and other auxiliary ingredients between the main electrodes.Under physicalchemical optimal condition, inorganic and organic contaminants in wastewater are rapidly removed by subjecting to oxidationreduction, coagulation, adsorption, complexation, replacement and so on in the OFR Two types of organic pollutants, phenol and chloral hydrate as the objects of the catalytic degradation mechanism with the OFR technique were studied The results indicate that is actually the oxidation of hydroxyl radical (·OH) which can be produced rapidly from the first yielded H2O2 in the OFR·OH in the treating process of the OFR with the method of spintrapping ESR was discovered Finally, the treatment for various wastewater(domestic sewage, printing and dyeing wastewater, pharmaceutical industry wastewater ) with the OFR were investigated
