摘要
以进(原)水箱、蠕动泵、藻类生物膜反应器、斜板沉淀池、超滤膜装置和出水箱构建新型藻类膜工艺系统,由斜生栅藻在立体弹性聚氯乙烯载体上形成藻类生物膜,并在连续光照度为3500 lx、室温、水力停留时间为4 d的条件下,研究了系统对南宁市南湖水的处理效果。结果表明:在连续15 d的动态试验中,藻类膜工艺系统对南湖水中COD、TP、NH3-N和TN的平均去除率分别为52.61%、90.42%、91.47%和77.39%;藻类膜反应器中pH值、DO和温度分别平均为10.38、12.8 mg/L和32.3℃,温度比室温平均高约4℃。藻类膜工艺系统具有较强的抗负荷冲击能力,对低氮、磷营养物的湖泊水具有良好且稳定的去除效果。
An algae biofilm process system consisted of influent tank,peristaltic pumps,algae biofilm reactor,inclined plate sedimentation tank,ultrafiltration device and effluent tank was built.In the algae biofilm reactor,algae biofilm was formed by Scenedesmus obliquus on the surface of stereo elasticity PVC filler.The treatment effect of Nanhu Lake water was studied under the condition of continuous illumination intensity of 3500 lx,room temperature,and HRT of 4 d.The results showed that,after 15 d continuous dynamic experiments,the average removal rates of COD,TP,NH3-N and TN were 52.61%,90.42%,91.47% and 77.39%,respectively.The pH,DO,and temperature in the reactor were 10.38,12.8 mg/L,and 32.3℃.The average temperature in the reactor was 4℃ higher than the room temperature.The algae biofilm process system demonstrated a strong resistance to the influent load,had good and stable removal effect on lake water with low nitrogen and phosphorus nutrients.
