海绵铁处理洗浴废水中LAS的试验研究

Study on Removal of LAS from Bathing Wastewater with Sponge Iron

研究了以海绵铁对洗浴废水中阴离子洗涤剂十二烷基苯磺酸钠(LAS)的处理。静态实验结果表明,在铁锰比为6∶1、反应时间为60min时,海绵铁对洗浴废水中LAS的处理效率可达83%以上。动态实验结果表明,LAS含量为4.3mg/L的洗浴废水,以4L/h的流量经海绵铁柱处理后,LAS去除率可达94%以上。

Study was made on the treatment of bathing wastewater containing LAS with sponge iron ,and the reaction mechanisms were investigated. Static experimental results showed that the removal rate of LAS from bathing wastewater was over 83%under the condition of Fe = Mn=6 ： 1 , reaction time was 60 min. Dynamic experimental results showed that treating bathing wastewater contained 4.3mg/L LAS at the flux of 4L/h through sponge iron column, the removal rate of LAS was over 94%.
