摘要
介绍百乐克污水处理工艺的特点,监测了各点总磷实际变化情况,总磷去除率为22%,不能达标排放,加铝盐和铁盐均可以达到排放标准。最佳的除磷工艺是脱水污泥直接进入曝气池,经5 h曝气,总磷<0.5 mg/L,去除率达92%,达到国家规定的一级排放标准。
The characters of Biolak process were introduced.The actual change in total phosphorus at each monitoring point was monitored.If the removal rate of phosphorus was 22%,the wastewater could not meet the national discharge standard.The discharge standard can be if the mastewater treated by adding aluminum or iron salts,then it could meet the discharge standard.The best way to remove phosphorus was to make the dewatered sludge go directly to the aeration basins with an aeration of 5 h.As a result,the total phosphorus was less than 0.5 mg /L with the removal rate of 92%,which could meet the first-class of the national discharge standard.
