| 摘 要： | 用混凝气浮技术处理处于富营养化状态的同济大学校园内景观水,通过正交试验复配了一种能够高效去除藻类、浊度和TP的混凝药剂,并研究了加药量、表面负荷和絮凝反应时间对处理效果的影响.在加药量为20 mg/L、表面负荷为2.0 mm/s和反应时间为4.5 min的最佳试验条件下,对藻类、浊度、TP、TN和COD的平均去除率分别达93.2%、89.5%、74.9%、33.8%和43.5%,混凝气浮技术可显著改善景观水体富营养化状况.

| Abstract: | Eutrophic landscape water in Tongji University was treated by coagulation and flotation technology.A kind of coagulant that can effectively remove algae,turbidity and TP was prepared through orthogonal experiment.The influences of dosage,surface loading and flocculation time on the treatment effect were investigated.Under the optimal conditions of dosage of 20 mg/L,surface loading of 2.0 mm/s and flocculation time of 4.5 min,the average removal rates of algae,turbidity,TP,TN and COD can reach 93.2%,89.5%,74... |
