| 摘 要： | 对山东某城市污水处理厂散发的恶臭气体进行除臭研究,考察了除臭生物滤池的运行效果、工艺影响因素和除臭生物滤池内微生物相特点。结果表明:(1)在进气量为828 m3/h、气体停留时间为30 s、硫化氢和氨进气质量浓度分别为0.5~28.4、0.9~34.3 mg/m3的条件下,稳定运行时,大部分时间硫化氢和氨去除率分别达98%和80%以上,而且除臭生物滤池对于进气负荷具有较强的抗冲击能力。(2)当填料含湿量为43.6%~63.4%时,硫化氢去除率在90%以上;氨去除受填料含湿量的影响较大,填料含湿量越高越利于氨的去除。(3)在处理低浓度含硫化氢和氨的恶臭气体时,生物除臭工程可以在低填料pH(3.0左右)下长期运行,并保持较高的恶臭气体去除率。(4)运行第60天后,当温度为10℃以上时,硫化氢和氨去除率几乎不受影响;第169天后,当温度降至10℃以下时,硫化氢和氨去除率均有一定程度的下降,最低分别为94.6%和79.8%。(5)除臭生物滤池稳定运行时,优势硫氧化菌主要为嗜酸性硫细菌。
