【摘要】 通过模拟水解酸化-好氧工艺,并以模拟印染废水为处理对象,比较分析了50%与80%的回流比下,水解酸化池与好氧池中污泥胞外聚合物与微生物疏水性的变化,探讨了最适回流比。结果表明,回流比为80%的工艺的污泥胞外聚合物、微生物疏水性及污泥性质优于回流比为50%的工艺。更多还原

【Abstract】 Stimulated printing and dyeing wastewater has been treated by hydrolysis acidification-aerobic process. The changes of sludge extracellular polymers and microorganism hydrophobic nature in hydrolysis acidification pool and aerobic pool when reflux ratios are 50% and 80%,respectively,are compared. The optimal reflux ratio is discussed. The results show that when reflux ratio is 80%,the sludge extracellular polymer and microorganism hydrophobic nature are superior to that when reflux ratio is 50%.更多还原
