在缺氧的环境下，利用零价铁（ZVI）和硫酸盐还原菌（SRB）协同处理含铀废水，通过正交实验考了察初始pH，铀的初始浓度，SO4^2-，NO3-对ZVI—SRB协同处理含铀废水的影响．结果表明，铀的初始浓度对ZVI—SRB协同处理铀废水的影响最大，其次是NO3-，pH值，SO42-；在500mL的水样中，其最佳的还原条件是-pH为5，SO4^2-为3000mg／L，NO3-为400mg／L，铀的初始浓度为160mg／L；在最佳还原条件下，铀的去除率为93．49％．

Wastewater containing uranium was treated by ZVI - SRB under hypoxic conditions. The initial uranium concentration, SO42-, NO3 - and pH on ZVI- SRB uranium precipitation are studied through orthogonal experiment. The result shows that the initial uranium concentration influencesmost greatly on the removal rate, following SO42- , NO3 - and pH. The optimal removal conditions for 500 mL wastewater containing uranium are the initial uranium concentration 160 mg/L, pH5, SO42- 3 000 mg/L, NO3 - 400 mg/L. The removal effic...
