| 摘 要： | 采用CAST工艺处理寒冷地区市政污水，系统在常温、低温条件下运行良好，处理效果稳定，出水可以达到国家要求的一级B类排放标准，对COD、BOD的平均去除率均超过90％，NH3-N的平均去除率均超过84％。而且在进水水质变化较大的情况下，系统也表现出较强的抗冲击负荷能力。

| Abstract: | The study on the treatment of Municipal wastewater in the northeast of china by CAST showed that reliable and stable treatment results could be achieved.During the adjusting,the bio-system was in a high performance in the season with both normal inlet temperature and lower temperature.During the experiment,the removal of COD,BOD,The removal efficiency of NH3-N higher than 84%.The quality of the effluent is fulfill the standard in a steady state.the effluent can fulfill the national standard for the class Ⅰ wastewater effluent.The system has strong capacity to treat the water with suddenly changed quality. |
