| 摘 要： | 在非稳态条件下,采用AAO剩余污泥为种泥、聚丙烯环为填料启动生物滴滤塔,处理实际市政污水厂细格栅H2S恶臭气体.研究了生物滴滤塔的启动、稳定阶段的运行模式,在空床停留时间为14 s,进气浓度2. 02～319. 19 mg·m-3,环境温度为7. 8～32. 5℃条件下,平均出气浓度为13. 08 mg·m-3,平均去除率达到91. 8%,最高去除负荷达到78. 37 g·(m3·h)-1.在247d运行中,监测到生物滴滤塔压降在长期运行中维持稳定在96 Pa·m-1.高通量测序表明,生物滴滤塔内的微生物群落发生了改变,Shannon指数由4. 99降低至3. 75,但Pseudomonas和Thiobacillus等功能菌的存在解释了生物滴滤塔较好的去除性能.结果表明,在非稳态条件下,以AAO剩余污泥为种泥的生物滴滤塔可实现H2S的高效去除;聚丙烯环作为填料可以在长期运行中维持稳定的压降;微生物群落在长期高浓度的H2S环境中,多样性降低,但降解性能可以得到提高.
