在北京第二毛纺织厂建成的日产水能力1万吨的加速澄清滤池正在试运行中。该滤池的水源取自北京京密引水渠,水质较好,常年浑浊度在25度以下,暴雨后可达350度,冬季是低温低浊期。处理后水质要求符合国家饮用水标准。该池的池型为矩形(见图),原水由池底进入池体,中部为机械搅拌反应区,两旁是沉淀过滤区,两区之间的夹层是滤料反冲洗水排水通道,最外侧是双层清水渠道,上
The accelerated clarification filter with a daily production capacity of 10,000 tons of water produced at the Second Woolen Textile Factory in Beijing is in trial operation. The water source of the filter tank is from the Jingmi diversion canal in Beijing. The water quality is good, the annual turbidity is below 25 degrees, and it can reach 350 degrees after heavy rain. In winter, it is low temperature and low turbidity period. The treated water quality meets the national drinking water standards. The pool is rectangular (see figure). The raw water enters the pool from the bottom of the pool. The middle part is the mechanical stirring reaction area. On both sides is the precipitation filtration area. The interlayer between the two areas is the filter backwash water drainage channel. It is a double water channel.
