摘要
研究了循环式活性污泥法中厌氧生物选择区的停留时间、进水有机物浓度和系统中泥龄、曝气时间等运行参数对选择区内厌氧释磷以及有机物的吸收贮存的影响。结果表明 ,选择区停留时间 lh,系统泥龄 5 d,曝气 2 h,进水有机物浓度 COD/ TP=6 0～ 70 ,选择器中释磷效果及微生物的吸附性能最优 ,可去除进水中 78%的 COD。而且污泥沉降性能良好 ,试验运行过程中 ,SVI一直保持在 30～ 4 0 m l/
Study was made on the influence of the operational parameters on the release of phosphorus and storage capacity of the mixed liquor in the anaerobic selector in the cyclic activated sludge technology.The result showed that when the HRT in the selector was 60min and the sludge age?aeration time?the influent COD/TP in the whole system were 5d?2h and 60～70 respectively,the release of phosphorus and the storage capacity of the mixed liquor in the selector reached the maximum,and 78 percent COD could be removed in it.During the experimental process,the sludge had a good settling ability,and the SVI reached values of 30～40ml/g.
