在连续光照强度为3500 lx,温度为(25±2)℃的实验条件下,以硝酸钠、硫酸铵、磷酸二氢钾为氮磷营养源,配制1800 mL模拟废水,其总磷( TP)、总氮( TN)、氨氮( NH4+-N)的初始浓度分别为10.57、36.56、19.40 mg/L,以立体弹性聚氯乙烯为载体,鞘藻( Oedogonium sp.)、水华鱼腥藻( Anabaena flos-aquae)、蛋白核小球藻( Chlorella pyrenoidosa)、斜生栅藻( Scenedesmus obliquus)、水网藻( Hydrodictyon reticulatum)、阿氏颤藻( Oscillatoria agardhii)等为实验藻种,进行了为期6 d的藻类膜脱氮除磷实验。结果表明:在6种实验藻种中,蛋白核小球藻最适合作为脱氮除磷废水处理的挂膜藻种,其藻类膜的TP、TN、NH4+-N去除率最高,分别为87.88%、87.27%、89.25%;藻类膜脱氮除磷能力与其叶绿素含量无正相关性,蛋白核小球藻藻类膜的叶绿素含量最小,为0.0654 mg/L,水华鱼腥藻藻类膜的叶绿素含量最大,为0.2450 mg/L。
在連續光照彊度為3500 lx,溫度為(25±2)℃的實驗條件下,以硝痠鈉、硫痠銨、燐痠二氫鉀為氮燐營養源,配製1800 mL模擬廢水,其總燐( TP)、總氮( TN)、氨氮( NH4+-N)的初始濃度分彆為10.57、36.56、19.40 mg/L,以立體彈性聚氯乙烯為載體,鞘藻( Oedogonium sp.)、水華魚腥藻( Anabaena flos-aquae)、蛋白覈小毬藻( Chlorella pyrenoidosa)、斜生柵藻( Scenedesmus obliquus)、水網藻( Hydrodictyon reticulatum)、阿氏顫藻( Oscillatoria agardhii)等為實驗藻種,進行瞭為期6 d的藻類膜脫氮除燐實驗。結果錶明:在6種實驗藻種中,蛋白覈小毬藻最適閤作為脫氮除燐廢水處理的掛膜藻種,其藻類膜的TP、TN、NH4+-N去除率最高,分彆為87.88%、87.27%、89.25%;藻類膜脫氮除燐能力與其葉綠素含量無正相關性,蛋白覈小毬藻藻類膜的葉綠素含量最小,為0.0654 mg/L,水華魚腥藻藻類膜的葉綠素含量最大,為0.2450 mg/L。

The removal effects of nitrogen and phosphorus from wastewater were investigated with six species of algal biofilm ( Oedogonium sp.,Anabaena flos-aquae,Chlorella pyrenoidosa,Scenedesmus obliqnus,Hydrodictyon reticulatum,Oscillatoria agardhii) under continuous light of 3 500 lx,temper-ature of (25 ±2)℃and PVC as the carrier.The volume of waste water was 1 800 mL ,and regarded NaNO3 , ( NH4 ) 2 SO4 , KH2 PO4 as nitrogen and phosphorus nutrition , the initial concentration of to-tal phosphorus (TP),total nitrogen (TN),ammonia nitrogen (NH4+-N) reached 10.57,36.56, 19.40 mg/L, respectively .The results showed that Chlorella pyrenoidosa was most suited to form al-gae biofilm ,and the removal efficiencies of TP , TN ,NH4+-N reached 87.88%,87.27%,89.25%, respectively .There were no positive correlation between removal efficiencies of nitrogen and phos-phorus and chlorphyll content of biofilm , chlorphyll content of Chlorella pyrenoidosa was lowest , reaching 0.065 4 mg/L, and Anabaena flos-aquae was highest ,reaching 0.245 0 mg/L.
