摘要
在藻菌共生流化床光生物反应器与活性污泥的好氧池相结合形成的"菌藻-菌"系统中,对人工配制的高浓度有机废水进行处理研究。主要研究了不同反应时间下,反应器进水、反应器出水、好氧池出水的DO和CO2的浓度变化情况,以及系统对COD、NH4+-N、PO43--P的去除效果,结果表明:藻菌共生之间的联系在一定程度可以通过系统中CO2和DO之间浓度变化的关系来反映;系统对COD、NH4+-N和PO43--P的去除效果较好,去除率最高可分别达到85.0%、73.1%和83.1%,与单独采用藻菌共生流化床光生物反应器处理相比,分别高出14.8%、7.3%和8.8%。
The bacterial-algal and bacterial system which was composed of a fluidized photobioreactor filled with the immobilized algal-bacterial beads,and followed by an aerobic pool with activated sludge was used to treat the artificial high concentration organic wastewater.The change of CO2 and DO concentrations from the different samples at different times,as well as the removal efficiency of COD,NH4^＋-N and PO4^3-P in this system were investigated.The results showed that the change of DO and CO2 concentrations in the system could reflect the growth situation of algae and bacteria of the algal-bacterial symbiosis system to a certain extent,the system had high removal efficiency of COD,NH4^＋-N and PO4^--P,the highest removal efficiency was 85.0%,73.1% and 83.1%,respectively,which was 14.8%、7.3%and 8.8% higher than the single fluidized photobioreactor with the immobilized algal-bacterial beads system respectively.
