摘要
黑臭水体具有异味重、毒性强和处理难度大等特点,对生态系统和人体健康会成较大危害,但常规的处理方法存在工程量较大和降解污染物较慢等问题。为了高效、彻底地解决黑臭水体的污染问题,梳理了城市黑臭水体成因及现状政策,总结了可使污染物转化的微生物修复法和化学处理法的原理和优势以及研究进展并分析了相关应用案例。结果表明:①微生物修复法具有无二次污染,成本较低,适用性广泛等优点,但处理效果容易受到外界因素(黑臭水体的浓度、温度和盐度等)影响,且前期培养驯化时间较长。②化学处理法可使黑臭水体得到高效、深度地处理,尤其是在处理紧急污染事故情况下,但是治理费用高昂,同时易对环境产生二次污染。
Black and odorous water bodies have the characteristics of heavy odor,strong toxicity and high difficulty in treatment,which can cause great harm to ecosystems and human health.However,conventional treatment methods have problems such as large engineering quantities and slow degradation of pollutants.In order to efficiently and thoroughly solve the pollution problem of black and odorous water bodies,this paper summarized the causes and current policies of urban black and odorous water bodies,the principles and advantages of microbial remediation and chemical treatment methods that can convert pollutants,and analyzes the research progress and relevant application cases.The results showed that microbial treatment method had the advantages of non-secondary pollution,low cost,and wide applicability.However,there were issues with the treatment effect being easily affected by external factors such as concentration,temperature,and salinity of black and odorous water bodies,as well as the long period of cultivation and domestication in the early stage.The chemical treatment method can efficiently and deeply treat black and odorous water bodies,especially in the case of emergency pollution accidents.However,the treatment cost was high,and it was prone to cause secondary pollution to the environment.
