摘要
采用木屑黄原酸酯(SCX)进行了处理铜离子废水试验,静态条件下研究了SCX-1对重金属离子的吸附性能,以及药剂用量、初水浓度、pH值和反应时间等条件对其效果的影响。结果发现,SCX对重金属离子具较好的吸附性能,pH值范围广,吸附量大,一次性去除率高达99%以上,处理后的水质达国家排放标准。含有重金属盐的残渣在自然水体中较稳定。
The experimentation of sawdust cellulose xanthate in treatment of copper wastewater are discussed in the paper, the study mainly include its capability in adsorbing heavy metal and the affect under the other factors such as: dosage, concentration of wastewater, pH, time of reaction, etc. The experimental result indicates that the cellulose xanthate has excellent adsorption capability, abroad pH. The rate of remove is over 99%. Water treated reaching the nation standard requires. The residue containing heavy metal is very steady in natural water.
