复合生物法处理炼化污水厂恶臭气体

摘要

The paper has introduced the mechanism, technique process, process control and practical effect of combined biological method, namely"Biological washing+bio-trickling filtration", in the treatment of odor pollution of sewage plant of a petrochemical enterprise. It also analyzed the factors influencing the performance of the biological treatment facilities. After practicing, the results indicate that combined biological process can produce a relatively ideal purification effect of odor for petrochemical enterprise in odor treatment of sewage plant with hydrogen sulfide treatment efficiency reaching up to 98%and Non Methane Total Hydrocarbon processing efficiency reaching up to 94%. The process takes advantage in simple operation, low cost and no secondary pollution.%介绍了“生物洗涤+生物滴滤”的复合生物法在某炼化企业污水处理厂治理恶臭污染的工艺原理、技术流程、过程控制和实践效果，分析讨论生物处理装置运行影响因素。实践结果表明，复合生物技术对炼化企业污水处理厂恶臭治理具有较为理想的恶臭净化效果，其中硫化氢处理效率可达到98%，非甲烷总烃处理效率可达到94%，且运行操作简便、成本低廉、无二次污染。
