SBR间歇曝气和充氧能力对溶解性微生物产物的影响

摘要

采用11.0L的SBR研究了曝气运行方式和充氧能力对活性污泥系统中SMP产出的影响.实验表明,相对于传统的SBR曝气方式,间歇曝气不仅提高系统的脱氮效率,而且还能够降低出水中SMP产出量,曝气运行方式对SMP产出量的影响超过SRT和充氧能力对其的影响;增强反应器的充氧能力会提高SMP的产出量.%A 11.0 L lab-scale SBR has been used for investigating the effects of different intermittent aeration and oxygenation capacity on SMPs generation in biological activated sludge systems. The experimental results indicates that compared with the traditional aeration method of SBR,the intermittent aerations could not only improve nitrogen removing efficiency,but also reduce SMP generation in effluent. The effect of intermittent aeration on SMP generation exceeds that of SRT and oxygenation capaciy. The experiments also indicates that,the increment in oxygenation capacity could also improve the SMP generation.
