摘　　要：通过生物陶粒、稀土瓷砂、普通陶粒对洗涤剂废水中难达标的LAS、TP的吸附与生物挂膜实验,结果表明,3种填料对LAS、TP的吸附等温式符合Langmuir模型。生物陶粒对LAS、TP的吸附去除率分别达到23.2%、27.2%,比稀土瓷砂、普通陶粒有更好的吸附性能,且对污水中污染物LAS、TP的浓度变化有很好的适应性,耐污染冲击负荷性能高于稀土瓷砂、普通陶粒,生物陶粒挂膜速度快,挂膜后处理水的COD达54 mg/L<60 mg/L,对COD处理效果好。因此,生物陶粒适于呈碱性洗涤剂废水的处理,是BAF处理洗涤剂废水的适宜填料。生物陶粒用作BAF填料处理洗涤剂废水,能有效提高COD、LAS和TP的去除率,使洗涤剂废水能处理达排放标准,这对于保护水环境具有重要意义。Through the experiments of bio-ceramic, rare earth porcelain sand, normal-ceramic adsorption of LAS, TP in detergent wastewater and handing bio-film, the results show that the three kinds of fillers adsorp- tion isotherm on LAS, TP conform to Langmuir model. The adsorption removal rate of bio-ceramic on LAS, TP reaches 23.2% ,27.2% respectively, bio-ceramic has better adsorption properties than rare earth porce- lain sand and normal-ceramic, and has very good adaptability on the changes of LAS and TP concentration , bio-ceramic has stronger pollution impact load resistant performance and quick speed of bio-film forming, The COD dilution is 54mg,/L witch is less then 60 mg/L after bio-membrane hanging. Bio-ceramic has good treatment effect on COD. Therefore, bio-ceramic is a suitable filXer to BAF treatment for the alkaline deter- gent wastewater. Bio-ceramic used as BAF to treat detergent wastewater can efficiently improve the removal rate of COD, LAS and TP and make the treatment of detergent wastewater meet the blowoff standard,witch is important to the protection of water environment.
