| 摘 要： | 以超高盐（盐度7％，以NaCI计）高磷榨菜废水为研究对象，考察了初始pH值对磷酸盐还原进程的影响。实验结果表明，初始pH值对磷酸盐还原除磷效能影响显著。初始pH为8时，磷酸盐还原除磷率达到最高，平均值为65．45％。同时，初始pH值还会影响污泥中活性磷的形成以及基体对磷化氢的吸附。此外，偏碱性有利于磷形态转化，且BD-P（主要是一些可溶性的、还原性强的、带有Fe-P化合物的集合）含量的高低调控着生物膜内间隙水中溶解态可反应性磷（DRP）和可还原水溶态磷（RSP）含量，最终决定着磷酸盐还原进程。随着初始pH值的升高，污泥对磷化氢的吸附能力降低导致污泥中结合态磷化氢（MBP）含量不断减少。 |
| 关 键 词： | 榨菜废水 初始pH值 磷酸盐还原 磷形态 结合态磷化氢 |

| Abstract: | Effect of initial pH value on phosphate reduction process was studied in treating hypersaline(salinity,7%,measured by NaCl) and high-phosphorus pickled mustard tube wastewater.Results show that there is a notably significant effect of initial pH value on phosphate removal.Phosphate removal rate achieves the top when initial pH value is about 8,and the mean is 65.45%.Meanwhile,initial pH value has influence on formation of active phosphorus in sludge and adsorption of matrix to phosphine.Furthermore,near alk... |
