BAF处理洗涤剂废水适宜填料的筛选试验研究
Experiment on screening of suitable filler for detergent wastewater treated by biological aerated filter
摘要
Abstract
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 adsorption 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 porcelain 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 filler to BAF treatment for the alkaline detergent 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.关键词
