摘要
考察了塔式生物滤池对不同污染物的去除效果。在水力负荷为14.5 m3/(m2·d),水力停留时间为2.45 h的条件下,使用聚丙烯塑料球为滤料挂膜36 d,待挂膜成功后进行连续进水。结果表明:经塔式生物滤池处理后,出水水质除TP满足二级标准外,其他指标均能满足《城镇污水处理厂污染物排放标准》(GB 18918—2002)一级B类标准;设计的塔式生物滤池系统具有较好的抗负荷能力。
The effect of the tower-type biological filter on the removal of different pollutants is investigated. Under the conditions below:hydraulic loading is 14.15 m3/(m2·d) and hydraulic retention time 2.45 h,using polypropylene plastic ball as filter materials for the 36-day biofilm formation,continuous inflow of water can be conducted till the tower-type biofilm formation is accomplished successfully. The experimental results show that only TP can meet the Second-level water quality standard,while all other indexes can meet the First-level standard specified in the Discharge Standard of Pollutant for Municipal Wastewater Treatment Plant(GB 18918—2002). This self-developed tower-type biological filter system has better load resisting capacity.
