摘要
针对某市河道黑臭水体的特性及污染物特点,采用“膜生物反应器(MBR)一体化工艺、补氧+生物膜、人工清淤”综合治理技术对其进行治理。实际治理结果表明,MBR一体化工艺出水水质达到了《城市污水再生利用景观环境用水水质》(GB/T18921-2019)的要求;补氧与生物膜的组合应用最大程度地消除了黑臭现象;采用人工清淤方式对河床内淤泥进行了全部清除,消除了内源污染;工程运行费用为70.39万元/年。该综合治理技术治理河道黑臭水体效果良好,适合在其他类似项目中推广应用。
According to the nature of heavily polluted water bodies and the characteristics of the pollutant in a city river course,the project in this paper has adopted the comprehensive treatment of“membrane bio-reactor(MBR)integrated technology,oxygen supplement plus carrier biofilm,and manual dredging”.The results show that the effluent quality with the MBR integrated process meets the requirement in“The Reuse of Urban Recycling Water-Water Quality Standard for Scenic Environment Use”(GB/T18921-2019);Combined application of oxygen supplement and carrier biofilm has eliminated the blackness and odor in the polluted water to the greatest extent;All the sludge in the riverbed has been removed by manual dredging,The project expense is 703900 yuan per year.In this project,the expected result has been achieved for the treatment of highly polluted water bodies by this comprehensive treatment technology,which also applies to the other similar projects.
