城市污水处理厂恶臭对环境影响的评价及预测

Assessment and Prediction of Influence of Stench in Urban Sewage Treatment Plant on Environment

为进一步消除城市污水处理厂恶臭对环境的影响,以南通市某污水处理厂为例,在详细分析恶臭产生源强的基础上,对氨气和硫化氢两个污染因子进行了评价,采用导则推荐的模式定量预测了恶臭对厂界及周围居民点的影响程度,并提出了相应的控制措施.结果表明,污水处理厂在采取有效加盖防护措施的情况下,产生的恶臭对周边居民的影响较小.

In order to eliminate the impact of stench on the environment,a sewage treatment plant in Nantong is taken as an example for analysis.On the basis of analysis about the source strength of stench in the sewage treatment plant,the two pollution factors—ammonia and hydrogen sulfide are selected and assessed,the guidelines recommended mode is used to predict the influence on the plant community and residential areas,and also the effective control measures are put forward to guide sewage treatment plant under the normal operation.The results reveal that the stench of sewage treatment plant has little effect on the surrounding residents when the effective protective measures are taken.
