摘要
采用淹没式生物滤池系统对官厅水库入库水进行了生物预处理的可行性研究 .综合考察了生物滤池系统内的生化作用机理 ,对地表水中的好氧反硝化进行了探索性研究 ,并在水力负荷为 4m3 (m2 ·h)的情况下取得了 2 9%的脱氮率 .好氧反硝化对于低C
Submerged biofilter system was used to investigate the feasibility of biological pretreatment for surface water entering into the Guanting Rreservoir. The biochemical mechanism of each biofilter was analyzed in detail. Heuristic study on aerobic denitrification for surface water was also conducted and nitrogen removal rate of 29% was achieved under hydraulic loading of 4?m 3/(m 2·h). Aerobic denitrification provided a novel technology of biological nitrogen removal for surface water with low carbon/nitrogen ratio.
