微电解——接触氧化法处理染化废水

THE RESEARCH OF DYING WASTES TREATMENT BY MICRO ELECTROLYSIS CONTACT OXDATION

利用铁屑在水溶液中腐蚀形成的微电解过程处理染料化工废水,可使染料废水中常见的硝基物转变为胺基物,从而有效地去除色度,提高污水的可生化性,同时COD的去除效果也很好。试验结果表明,微电解——接触氧化法比通常的石灰中和混凝沉淀——接触氧化法的处理效果高出一倍。

Using the micro-electrolysis process of iron filings corrosive in aqueous solution to treat dying wastes can transfer nitro-compound into amino-compound. There by it can efficiently reduce colors,enhance biodegradability of wastewater and get better removing COD as well. Such test result has shown that, micro-electrolysis-contact oxidation method is much more efficient than conventional coagulation settling by lime neutralization-contact oxidation method.
