生物滴滤塔处理VOCs和H_2S混合废气的工程实例

Engineering Example of Treatment of Mixed Waste Gas Containing VOCs and H_2S in Biological Trickling Filter

在浙江某化工厂建立了处理生产车间VOCs和自备污水站H2S混合废气的生物滴滤塔（BTF）。BTF经过12d完成启动。在启动之后的调试期间，混合废气中VOCs的质量浓度为200～400mg／m3,H2s的质量浓度为80-150mg／m3,BTF对VOCs和H2S的去除率均分别能保持在86％和96％左右。VOCs和H2s均达标排放。

A biological trickling fiher（BTF） treating mixed wastegas containing VOCs from produce department and H2S from own sewage plant was established in a chemical plant in Zhejiang. The BTF completely started in 12 d. In the period of commissioning after start, the mass concentrations of VOCs and H2S were 200-400 mg/m3 and 80-150 mg/m3, and their removal rates could maintain at 86% and 96%. VOCs and H2S both reached emission standard.
