印染工业废水处理厂点源残余铝的环境生态行为

摘要

铝是一种重要的元素也是一种重要的环境生态毒素.铝系絮凝剂在太湖地区工业废水处理中广泛使用,但铝的残余比(残余铝/加入铝)在印染工业废水处理厂的排放水中是最高的,其平均值9.28%.排放水中铝的浓度变化在0.43～268.75mg/L之间,权值为12.26mg/L.本文主要探讨印染工业废水处理厂点源排放铝及其伴随物表面活性剂对受纳水体的环境生态影响.%Aluminum- type- flocculants are used extensively in Taihu district. The remaining ratio (adding aluminum/remaining aluminum) in dyeing wastewater is the highest ratio among all kinds of sewage,its average value is about 9.28% dose;the range of remaining aluminum concentration is 0. 43 ～ 268.75mg/L, weighted average value is 12.26mg/L.The influences of aluminum and its accompanying surfactants in sewage drained from dyeing point resources on receiving aquatic environmental ecosystem are studied.
