竹醋对生活污水好氧处理的强化作用初步研究

采用在生活污水好氧处理之前投加外源物质的方法 ,研究了竹醋 (Bamboo Vinegar,BV)及其主要有机成分 (乙酸 )对污水好氧处理效果的强化作用。结果表明 :1当 VBV/ V污水 的比值达到1 / 1 0 6时 ,BV对污水 CODcr的去除有极显著的强化作用 :CODcr去除率比不加竹醋的对照组提高1 0 %。但是 ,BV对污水中 NH+ 4 - N,T- P的去除率没有影响。 2乙酸单独使用亦可显著提高污水CODcr去除率 ,当 V乙酸 / V污水 为 1 / 1 0 7时 ,强化效果最好 ,CODcr去除率提高 1 3%。由于乙酸具有与BV相似的作用特点 ,所以认为 BV对污水处理效果的强化作用来自其中的乙酸。为了将 BV应用于污水处理中 ,需要进一步研究确定 BV对活性污泥法、生物膜法处理污水的强化效果

A Pilot Study on the Bioaugmentation of Bamboo Vinegar (BV) for the Aerobic Treatment of Domestic Sewage

s: The bioaugmentation of bamboo vinegar (BV) and its main organic constitute(acetic acid) for the aerobic treatment of domestic sewage was studied by detecting the removal percentages of 3 pollutants after adding these two substances into the sewage. It showed that, when the volume ratio of BV to sewage ( V BV / V S) was 1/10 6 , BV strengthened the removal of CODcr in sewage significantly with an increment of 10% in comparison with the control experiments. But the augmentation of BV to NH + 4 N and T P was not observed at all ratios of V BV / V S. The greatest augmentation of acetic acid (AA) was obtained at the V AA / V S ratio of 1/10 7, with an increment of 13% in the removal of CODcr in comparison with the control experiments. It was thought that the bioaugmentation of BV to sewage treatment resulted from acetic acid because it had the same effects on the removal of pollutants as BV. In order to apply BV in the treatment of domestic sewage effectively, it is necessary to study its augmentation in the activated sludge process and the biological membrane method.
