摘要
包头市北郊水质净化厂是包头市第一座以二级处理等级建设运行的城市污水处理厂,设计规模为日处理污水7万m3,日处理中水4.5万m3。污水采用传统活性污泥处理工艺,污泥采用浓缩-螺滤脱水工艺,中水处理采用沉淀-过滤-消毒工艺。本文针对北方城市污水处理特点介绍了各工艺构筑物的设备配置、设计参数及运行情况。
With design scale of 70000m^3/d for sewage treatment and 45000m^3/d for intermediate-water treatment, the watr purification plant is the first municipal sewage treatment one constructed according to the second grade treatment in Baotou City. The sewage treatment adopted traditional activated sludge treatment technique;the sludge process adopted concentration-spiral filtration dehydrated technique,and the intermediate-water adopted precipitation-filtration-sterilization technique. The paper introduces the equipment configuration, design parameters and operation conditions for various structures according to the characteristics of sewage treatment of the northern cities.
