摘要
以绥化市城市污水处理工程为背景,介绍了CAST工艺在冬季运行期间对COD、BOD5、TP和SS的去除效率,并对影响去除效率的因素进行分析。结果表明,系统在整个冬季运行期间,平均出水COD、氨氮、TP和SS浓度分别为48.3、0.96、0.71和9.35mg/L,不仅可长期稳定地满足《城镇污水处理厂污染物排放标准》中的一级B标准,且系统具有较强的抗冲击负荷能力。
The Suihua wastewater treatment plant is presented to show the removal efficiency of COD,BOD5,TP and SS in cold winter.The results show that the concentration of COD,ammonia,TP and SS in effluent was 48.3mg/L,0.96mg/L,0.71mg/L and 9.35mg/L,respectively.It can be concluded that the CAST process can be used in extremely cold regions totally.The system effluent can satisfied the national standard class Ⅱfor the municipal wastewater treatment steadily and the CAST process shows the strong capacity to treat the water with suddenly changed quality.
