【摘要】：通過Donnan滲析去除含鹽廢水中的氨氮,研究了鹽水初始濃度、NaCl與氨氮比例、攪拌強(qiáng)度以及溫度等對氨氮分離的影響。結(jié)果表明,降低鹽水濃度、NaCl與氨氮比可提高氨氮的去除率,攪拌速度由200 r/min提高到500 r/min時,氨氮的去除率從49.6%提高到54.3%,處理時間縮短。適當(dāng)提高溫度,可有效提高氨氮的分離效果。
[Abstract]:Ammonia nitrogen was removed from salt wastewater by Donnan dialysis. The effects of initial concentration of salt water, ratio of Donnan to ammonia nitrogen, stirring intensity and temperature on the separation of ammonia nitrogen were studied. The results showed that reducing the ratio of salt water concentration to ammonia nitrogen could improve the removal rate of ammonia nitrogen. When the stirring speed was increased from 200 r/min to 500 r/min, the removal rate of ammonia nitrogen increased from 49.6% to 54.3, and the treatment time was shortened.
