【摘要】 营养问题是污水处理中最为重要的问题之一,废水营养比例失调最终会影响到生化处理单元的效果。为此,有必要对活性污泥所需外加营养及其合理比例进行研究。本试验对乳酸发酵废水中污泥所需的营养配比进行试验研究,确定最佳比例,以加快微生物的生长繁殖,维持系统较高的去除率。更多还原

【Abstract】 The nutrition problem was one of the most important problems in the sewage treatment.The out of balance of nutrition-allocated proportion in waste water could finally affect the effect of biochemical processing unit.Therefore,it was necessary to study the reasonable proportion of the active sludge’s nutrition.The test was going to study the nutrients ratio which the sludge need in lactic-acid ferment wastewater,then determined the optimum ratio in order to speed up microbial growth,reproduction and maintaining a higher removal rate.更多还原
