以“蚯蚓粪-炭”为渗滤介质去除洗衣污水中的LAS的研究

洗衣污水是中国当前主要的生活污水之一。本研究试着将蚯蚓粪和炭按体积比混合组成渗滤介质,使洗衣污水从中渗透通过,对污水中的主要有害物质LAS（阴离子表面活性剂）进行吸附和降解。实验结果表明：洗衣污水经过这种混合介质（1︰1）的渗滤后,污水中的阴离子表面活性剂（LAS）的去除率达到96.78%,对洗衣污水起到明显的去污效果。

Study on Removing LAS in Laundry Wastewater Purification by Vermicompost-carbon Filtration Media

Laundry waste was one of the current main domestic sewage of our country.The investigation tried to make up percolating and filtrating medium with earth worm excrement and charcoal according to volume ratio,made the laundry waste water seep through the device,so as to achieve adsorption degradation of main harmful substances LAS（Anionic surfactant） in the foul water.It was indicated that after the process of percolating and filtrating,the removal rate of anionic surfactants（LAS） reached 96.78 %.It had come into being obvious decontamination effect to the laundry waste.
