摘　　要：以赣南地区低碳源城市污水为处理对象,研究了Uni Tank工艺小试装置的启动运行。结果表明:通过连续进水及调整人工配水与实际污水比例的方式对污泥进行驯化,培养至最后阶段,出水COD、TN、NH3-N和TP平均质量浓度分别为26.0、9.3、0.5、0.4 mg/L左右,污泥中出现原生动物,反应器启动成功。通过控制Uni Tank工艺的时间运行参数,可形成间歇的脱氮除磷空间。同时,边池进水时间与中池进水时间比例为2∶1时,NH3-N的平均去除率为83.0%,最高可达98.3%。Taking low-carbon source urban sewage in Gannan region,China,as a treatment object,the start-up operation of laboratory equipment of Uni Tank process has been researched. The results show that through continuous water feeding and adjusting the distribution ratio of artificial water and actual wastewater,the sludge has been acclimated and cultivated till the final stage. The average mass concentrations of effluent COD,TN,NH3-N,and TP are about 26.0,9.3,0.5,and 0.4 mg/L,respectively. And,protozoon appears in the sludge,which indicates that the reactor has been successfully started up. The space of intermittent denitrification and dephosphorizaion can be formed by controlling the time operation parameters of Uni Tank process. In addition,when the proportion of side tank water feeding time and middle tank water feeding time is 2∶1,the average removing rate of NH3-N is 83.0%,the highest removing rate can reach 98.3%.
