生物滴滤工艺-双水源供给技术除臭系统在城市水质净化厂中的应用

Application of Deodorization System with Biological Trickling Filter Process - Dual Water Source Supply Technology in Urban Water Purification Plants

摘要:

为了解决污水处理过程中产生的臭气问题。以厦门市筼筜水质净化厂臭气除臭提升系统为例，在确定并分析厂区污水臭气来源的基础上，采用生物滴滤工艺-双水源供给技术除臭系统处理污水处理过程中产生的臭气。排放出口的气体在线检测仪检测结果表明，除臭系统能够有效去除臭气中的恶臭物质；厂界无组织气体检测结果证实，在完成除臭系统提升工程后，厂区边界的大气环境指标均满足《城镇污水处理厂污染物排放标准》（GB 18918—2002）的限值要求。

Abstract:

To address the odor problems arising from sewage treatment process, taking the odor deodorization upgrading system of the Xiamen Yundang Water Purification Plant as an example, and on the basis of identifying and analyzing the sources of odorous gases within the plant, a deodorization system with a biological trickling filter process - dual water supply technology is used to treat the odor from the processes. The detection results of the gas online detector at the discharge outlet indicate that the deodorization system can effectively remove the odorous substances in the odor. The unorganized gas detection results at the plant boundary demonstrate that the atmospheric environmental indicators at the boundary of the plant area all meet the limit requirements of the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (GB 18918—2002) after the completion of deodorization system upgrade project.
