摘要
目前,环保政策极其关注污水处理厂的臭气排放并制定了排放标准。本实验依托3个并联的中试生物滴滤塔对污水提升泵站的H2S臭气展开研究,考察不同H2S进气负荷、停留时间、压降和填料填装方式(竹炭-陶粒分层填装、完全混合及全竹炭填装)等因素对H2S去除率的影响。对生物滴滤塔的出气浓度、滤出液p H、SO2-4离子等进行测试分析,建立传质、降解动力学模型,并分析。在停留时间为25 s连续进气条件下,考察进气负荷在0.59~5.00 g H2S/(m3·h)范围内生物滴滤塔对H2S臭气的去除表现效果。研究结果表明,各生物滴滤塔的去除率(RE)都维持在98%以上,而且出气浓度达到厂界废气排放三级标准;相较于完全混合填装方式,分层填装在去除H2S臭气时略显优势。采用Michaelis-Menten方程描述生物滴滤塔的去除表现,表观半饱和常数Ks和最大表观去除速率Vm分别为5.92 m L/m3和5.84 g H2S/(m3·h)。
