Abstract: Abstract:The general situation of reclaimed water reuse in Huaneng Beijing Cogeneration Corporation Limited was introduced. Considering the limit of site area, the lower input water turbidity and the smaller reserved capacity of the support equipments, the HW clarifying tank was selected to replace the circular clarifying tank. The technological process of the project and the main design parameters of each processing unit were expounded. After the HW clarifying technology was adopted, when the input water flow reaches to the design flow, the turbidity of the output water of the HW clarifying tank is between 0.4NTU and 0.9NTU, which meets the requirement of the design standard.
