好氧-富氧曝气生物处理在黑臭河涌原位修复中的应用
Application of black-odor river of aerobic-oxygen-enriched aeration biological treatment in-situ remediation
摘要
Abstract
In recent years,the necessity to improve the conditions of black-odor rivers has been emphasized repeatedly.In situ remediation technology was used in the Nanhai River of Guangdong province to control the black-odor pollution by inoculating it with dominant bacteria and multistage biological treatment of aerobic-oxygen-enriched aeration.The results showed that with the effects of photosynthetic bacteria and nitrobacteria,the dominant bacteria increased the quality of the overlying water,the water transparency went from 5 cm to 35 cm,and the black-odor pollution basically was eliminated.The removal rates of COD,NH3-N,BOD5,and TP were from 68.1％ to 78.7％,79.8％ to 80.1％,84.8％ to 85.2％,and 76.4％ to 83.6％,respectively,and were attributed to the functions of indigenous microorganisms,which helped the degradation of the organic pollutants.As a result,the self-purification capacity of the river improved.关键词
