Abstract: In this paper,taking acrylic wastewater from the sewage treatment workshop of a chemical fiber company in Jilin as an object,the effect of Fe0 on acrylic wastewater treatment in SBBR reactor was studied via parallel comparison test.The test results showed that:(1)It could improve the start-up rate of SBBR reactor by adding Fe0.(2)While the reactor was at the stable operation stage,in 2# reactor with added Fe0 and 1# reactor without adding Fe0,the average removal rates of CODCr were 70.7% and 60.5% and the average removal rate of NH3-N were 60.6% and 13.5%,respectively.The average removal rate of CODCr and NH3-N were improved by 10.2% and 47.1% by adding Fe0.(3)The mixed liquor suspended solids(MLSS)and mixed liquor volatile suspended solids(MLVSS)in 2# reactor with added Fe0 were 1.60 and 1.35 times than those in 1# reactor,respectively.Adding Fe0 was beneficial to the growth of heterotrophic nitrification bacteria-Alcaligenes sp.,thus significantly improving NH3-N removal rate.

摘要: 以吉林某化纤集团公司污水处理车间腈纶废水为对象,通过平行对比试验考察了Fe0对SBBR反应器处理腈纶废水性能的影响。结果表明:(1)添加Fe0可提高SBBR反应器的启动速率;(2)在反应器进入稳定运行阶段后,添加Fe0的2#反应器与对照组1#反应器的CODCr平均去除率分别为70.7%和60.5%,NH3-N平均去除率分别为60.6%和13.5%,外加Fe0的SBBR反应器CODCr与NH3-N平均去除率分别提高了10.2%和47.1%;(3)添加Fe0的2#反应器的MLSS与MLVSS分别是对照组1#反应器的1.60倍和1.35倍。同时,添加Fe0更有利于异养型硝化菌——产碱杆菌属的生长,从而大大提高了反应器NH3-N的去除率。
