| 摘 要： | 以模拟废水为处理对象,考查了活性污泥在稳定期、污泥颗粒期、曝气改善期三种状态下对CODcr和浊度的去除效果.实验结果表明：稳定期的CODcr去除效果最好,说明絮体污泥比颗粒污泥更有利于污染物的去除.曝气改善期浊度去除率最好,说明污泥颗粒化有利于提高污泥的沉降性能并降低出水浊度;同时,污泥颗粒化后需要提供合适的曝气强度使颗粒污泥保持合适的粒径,以稳定系统的出水水质.

| Abstract: | With simulated wastewater as object of treatment,the removal effect of CODcr by activated sludge in the stable phase,granular phase,and enhanced aeration phase was examined.The results show that the removal effect of CODcr is the best when the activated sludge is in the stable phase,which indicates floc sludge outdoes granular sludge in removing pollutants;that the turbidity is most effectively removed when the sludge is in enhanced aeration phase,which means the granulation of sludge is helpful in improving the deposit of sludge and decreasing the turbidity of output water;and that appropriate aeration intensity is required after granulation of sludge to keep proper size of the particles and the quality of output water. |
