蜂窝陶瓷载体生物膜工艺的除磷试验

Study on phosphorus removal in biofilm process with ceramic honeycomb carrier

分别采用序批式生物膜反应器（SBBR）和A／O工艺进行比较，利用蜂窝陶瓷作为生物膜载体。分别处理模拟的受严重污染的地表水．重点研究磷的去除规律及影响因素，实验结果表明：厌氧时间为2．5h，好氧时间为6h；进水COD／TP为50—60，从SBBR出水中，磷浓度小于0．5mg·L^-1，总磷去除率大于85％，而A／O工艺的除磷率不到50％．

Sequencing Biofilm Batch Reactor （SBBR） and A/O process were used for the treatments of the simulated wastewater, specially for phosphorous removal, based on biofilm process with ceramic honeycomb carrier. When the HRTs of anaerobic tank and aerobic tank were 2.5 h and 6 h, respectively, the influent COD/TP concentration ratio is 50 -60, the effluent concentration of phosphorus from the SBBR is less than 0.5 mg · L^-1, and the removal efficiencies of total phosphorus were above 85%, but the removal efficiencies of the A/O process were less than 50%.
