| 摘 要： | 采用生物陶粒滤柱作为预处理工艺,考察了其对滏阳河水的处理效果以及影响因素,并确定了运行参数。试验结果表明:生物滤柱对各种藻的去除效果不同,且去除率随滤速的上升而降低;有机物的去除率受滤速影响不大,但随着温度的上升而提高。生物预处理不但能够降低混凝剂的用量,而且使溶解氧增大,改善了水质。

| Abstract: | The treatment efficiency and influencing factors of water from Fuyang River were investigated by biological ceramic filter pretreatment, and the operational parameters were determined. The result showed that the removal efficiency of algae species by biological filter was different, and the removal rate decreased as the filtration rate increased. The filtration rate had a little impact on the removal of organic matter, but increased as temperature rose up. The biological pretreatment process could not only reduce the dosage of coagulant, but also increase dissolved oxygen, and improve water quality. |
