MBBR在饮用水预处理中的中试应用研究

Study on the trail application of MBBR in drinking water pretreatment

在盐城某自来水厂内开展MBBR中试研究,考察其对水体CODMn、氨氮的去除效果,为MBBR工艺在饮用水预处理中的应用提供参考依据。结果表明:MBBR工艺对饮用水源水CODMn和氨氮具有较好的去除效果,去除率分别可达10.2%和45.8%;MBBR工艺具有较强的抗冲击性,水量为设计值的400%时,氨氮仍有49%的去除率;30%是最佳的填料投加比,此时CODMn的去除率可达21%,同时能保证氨氮能稳定达标。

The MBBR pilot test was carried out in a waterworks in Yancheng to investigate the removal effect of CODMn and ammonia nitrogen in water,and to provide reference for the application of MBBR process in drinking water pretreatment.The results showed that the MBBR process had a good removal effect on CODMn and ammonia nitrogen in drinking water source,and the removal rates were up to 10.2%and 45.8%,respectively.The MBBR process had strong impact resistance.When the water volume was 400%of the design value,the ammonia nitrogen still had a removal rate of 49%,and 30%was the best filler ratio when the removal rate of CODMn could reach 21%,and the ammonia nitrogen could be stably achieved.
