【摘要】用曝气生物滤池处理焦化废水的研究表明,在曝气量(Q)=0.25 L/m in,温度(T)=20℃,pH=8,反冲洗周期为3个运行周期内,NH3-N的去除速率达44 mg/L.h。同时在滤池中出现了亚硝酸盐积累现象,且受反冲洗的影响较大。更多还原

【Abstract】 Biological aerated filter（BAF） was used to treat coke-plant wastewater.The experimental results showed that the removal rate of NH₃-N was reached to 44 mg/L·h under the conditions:Q=0.25 L/min,T=20℃,pH=8,the back wash cycle under three running cycles.At the same time,the accumulation of nitrite was found.It was mainly affected by back wash.更多还原
