摘要
底泥内源污染是导致水体黑臭的重要原因之一。简述了黑臭水体底泥内源污染治理技术,包括物理修复技术、化学修复技术、生物修复技术及复合修复技术,并进行了对比分析。总结了在实际治理工程中,应结合水体特征及底泥污染特征选取合适的治理技术复合治理,达到生态修复的目的,并防止返黑返臭问题。底泥内源污染治理需朝着水生态修复的方向进行,在底泥内源污染治理技术的研究方向上,提出了建议:以生态修复技术研发为主,以物理或化学技术为辅,加快修复效率,彻底解决底泥内源污染问题。可为黑臭水体底泥内源污染治理工程提供一定的参考。
Sediment endogenous pollution is one of the most important reasons for the black and odorous water.In this paper,the control technologies of sediment endogenous pollution in black and odorous water body were briefly described,including physical remediation technology,chemical remediation technology,biological remediation technology and composite remediation technology.The advantages and disadvantages of several technologies were compared.It was concluded that in the actual treatment project,the appropriate combination of treatment technologies should be selected according to the characteristics of water body and sediment pollution characteristics,so as to achieve the purpose of ecological restoration and prevent the problem of returning to black and odor.The treatment of sediment endogenous pollution should be carried out in the direction of water ecological restoration.In direction of control technologies of sediment endogenous pollution,it was suggested that ecological remediation technologies should be mainly developed,supplemented by physical or chemical technologies,so as to speed up the remediation efficiency and thoroughly solve the problem of sediment endogenous pollution.At the same time,this paper could provide reference for the treatment of black and odorous water sediment.
