印染工业废水处理厂点源残余铝的环境生态行为(英文)

Environmental and Ecological Behaviors of Remaining Aluminum from the Dyeing Point Resources

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 9.2 8%。排放水中铝的浓度变化在 0 .4 3～ 2 6 8.75mg/L之间 ,权值为 1 2 .2 6mg/L。

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.
