污水过滤罐过滤过程中会在顶部形成不流动的“死”油区,难以去除。在过滤罐运行过程中,滤料污染加剧、缩短滤料有效寿命。为解决这一问题,在污水过滤罐顶部安装一个集油管,最后进入400立方米回收水池。过滤罐增加排油流程是其工艺改进的一个新举措,该方法效果显著,过滤罐滤后水质合格率明显上升。 Sewage filtration tank will form a non-flowing “dead” oil zone at the top during filtration, which is difficult to remove. In the operation of the filter tank, filter media pollution, shorten the effective life of the filter. In order to solve this problem, an oil collecting pipe is installed at the top of the sewage filter tank, and finally, the 400 cubic meter recycling water tank is taken. Filter tank to increase the oil discharge process is a new measure to improve its process, the effect of this method is significant, filtration tank water quality qualified significantly increased.
