摘要
印染废水通过铁屑滤床后,脱色率和COD 去除率分别达95%和90%以上。其原理是多种作用综合效应的结果,主要是氧化还原,其次是絮凝。影响处理效果的因素有多种,主要是作用时间和pH 值。该法具有廉价、有效、易行的特点,甚有发展前途。
If dyeing-house waste water passes through iron chips filter,over 95% and 90% of co-lout and COD may be removed respectively.The principles are a co-operating effect of afew functions,the main of which is oxidation-reduction,and the next is floculation.Fac-tors affecting the treament efficiency have many kinds,the principal ones are reaction timeand pH-value.The method has advantages of low cost,high efficient,easy commercization,and thus has a bright prospect.
