云南天然气化工厂水预处理增补的机械搅拌加速澄清池(以下简称加速澄清池),自1980年6月开车以来,已经受了两年的洪水考验,取得了一定的运行经验,找出了一些水质差的原因,采取了一些改进措施。该加速澄清池(见图1)接收1～2~*沉砂池的自然沉砂出水,或接收加有机高分子絮凝剂降低了高浊度后的出水,经加硫酸铝混凝澄清后浊度小于20毫克/升,再去虹吸滤池过滤,浊度小于5毫克/升、加氯后并保持
The mechanical mixing and accelerating clarification tank (hereinafter referred to as acceleration clarifier) supplemented by water pretreatment in Yunnan natural gas chemical plant has been undergoing two years of flood test since it was started in June 1980. It has obtained certain operating experience and identified some The reasons for poor water quality have taken some improvement measures. The accelerating clarifier (see Figure 1) receives 1 to 2~* grit chambers for natural sedimentation, or receives organic polymer flocculants to reduce the high turbidity water, and is coagulated and clarified by adding aluminum sulfate. Degree less than 20 mg/l, then go to the siphon filter, the turbidity is less than 5 mg/l, chlorinated and kept
