摘要
通过两段曝气生物滤池(TUBAF)处理城市生活污水的试验研究,考察了容积负荷、水力负荷、水温等对处理效能的影响。结果表明:污染物容积负荷的增加,TUBAF的污染物去除能力会逐渐降低。就COD、氨氮、SS去除效能而言,两段上向流BAF可以承受较大幅度的水力负荷变化;当进水水温上升,反应器运行性能相应提高;BAF C段、BAF N段的DO分别控制在2～3mg/L和3～5mg/L是适宜的。试验过程并未发现PH值对处理效果有显著影响。BAF C段采用半软性,BAF N段采用粒径较小的酶促好氧填料,这种组合填料方式能有效延长运行周期,达到良好的COD和氨氮及SS去除效果。
The experiment was carried out on the use of TUBAF for treatment of municipal wastewater and study on the effect of the cubage load,waterpower,temperature of the water.The results showed that the increase of the cubage load,the worse of the remove of waste by TUBAF.TUBAF can endure the big variety of the waterpower.When the T of the water increases,the efficiency of the reactor gets better.The optimal DO of the stage BAF C and BAF N is 2～3mg/l and 3～5mg/l.The PH value doesn＇t affect the efficiency of the reactor evidently.The stage BAF C and BAF N adopt half-soft padding and granule padding respectively is better to prolong the period of the running,and is also better to remove of COD,NH3-N,SS.
