摘要
将南方某城市污水处理厂作为研究对象,首先调查和分析各个处理单元释放恶臭物质的成分及含量,并确定污染强度。结果表明:引起恶臭的主要物质成分为H2S。对H2S进行春、夏、秋、冬四季跟踪监测,结果显示:夏季>秋季>春季>冬季。同时,调查得出结论:该污水处理厂的恶臭污染源主要有污泥处理系统、三期A段系统、预处理系统和初沉池。
In this paper, the ingredient and content of odor released from constructions were investigated and analyzed in one municipal wastewater treatment plant in South China, and the pollution intensity were defined also.The result indicated that typi-cal odorous compound was hydrogen sulfide.By monitored the concentration of hydrogen sulfide seasonally, it is found that the or-der concentration is:summer>autumn>spring>winter.The major odorous sources were sludge treatment process.A phase of third constructions, pretreatment processes and primary sedimentation.
