碳纤维生态草技术协同曝气对黑臭水体的修复
|
摘要
为解决强化混凝法原位修复黑臭水体中易形成的二次污染和底泥负荷问题,通过模拟试验研究了新型碳素纤维(carbon fiber,CF)生态草填料协同曝气技术对强化混凝处理后的黑臭水体的净化效果。试验原水采自某流动性差的小型封闭黑臭水体,经高锰酸钾强化聚合氯化铝混凝沉淀处理后的出水作为试验用水,分别研究了空白处理、单独曝气处理、单独CF生态草修复和CF生态草协同曝气处理后水体中的浊度、氨氮、COD (chemical oxygen demand)和UV254(ultraviolet absorption)的净化效果。结果表明:CF生态草具有良好的亲水性、吸附性和生物亲和性,10 d后即可形成成熟较厚的活性生物膜。CF生态草协同曝气技术修复黑臭水体的效果显著高于其他三种处理方式,水体中的浊度、氨氮、COD和UV254的最高去除率分别达到95. 37%、80. 78%、77. 27%和77. 50%。可见CF生态草与强化混凝技术联用修复黑臭水体,可解决混凝沉淀技术易产生的二次污染和底泥负荷问题;强化混凝、曝气和CF草生态修复三种技术相组合的新型黑臭水体修复工艺,在黑臭水体的整治和修复中具有良好的发展前景。
In order to solve the problems of secondary pollution and sediment load which are caused in the in-situ remediation of of black-odor water body by enhanced coagulation,a new type of carbon fiber( CF) eco-grass filler combined with aeration technology was used to purify the black-odor water body after enhanced coagulation treatment by simulation experiments. The raw water was collected from a small,closed,black-odor water body with poor fluidity,and the effluent treated by potassium permanganate enhanced polyaluminum chloride coagulation was used as test water. The purification efficiencies of turbidity,ammonia nitrogen,chemical oxygen demand( COD)and ultraviolet absorption( UV254) in test water treated by blank processing,aeration,CF eco-grass restoration and CF eco-grass combined with aeration were studied. The results show that the CF eco-grass has good hydrophilicity,adsorption and biocompatibility,and the active biomembrane can be formed after 10 days. The effect of CF ecograss combined with aeration technology on the restoration of black-odor water body is significantly better than that of the other three treatment methods. The highest removal rates of turbidity,ammonia nitrogen,COD and UV254 are95. 37%,80. 78%,77. 27% and 77. 50%,respectively. It is concluded that the combination of CF eco-grass and enhanced coagulation technology can solve the problems of secondary pollution and sediment load easily caused by coagulation sedimentation technology,and the combination of enhanced coagulation,aeration and CF eco-grass restoration technology has a good development prospect in the remediation and restoration of black-odor water body.
