摘要
为研究船舶生活污水在收集处理过程中产生的臭气组分及浓度,文章对生活污水臭气来源和主要组分进行了理论分析,并对实验室污水池、实船不同运行负荷及运行状态下的生活污水处理装置释放的H2S、NH3和CH3SH进行定量检测。结果表明:船舶生活污水臭气中的主要成分为NH3,且超负荷运行的装置,甲板通气口处浓度最高可达304.08 mg/m3。
In order to study the composition and concentration of odor in marine sewage collecting and treatment process,the odor source and main composition are studied by theoretical analysis.At the same time,H2 S,NH3 and CH3 SH from laboratory sewage tank and sewage treatment device in different operating load and running status is quantitatively detected.The results show that the main composition of odor in marine sewage is NH3.In the gas released by the overloaded device,the maximum concentration of NH3 is 304.08 mg/m3 at deck gas outlet.
