Sewage Treatment Plant Reconstruction Project Design at Cold Area in the Northeast of China

Abstract:

Sewage treatment plant reconstruction project in cold area of China (the scale of processing is 20×10⁴m³/d). The project have adopted advanced MBR process for both lacking space and improving effluent quality requirements .After secondary treatment, sewage flow through invasive hollow fiber membrane module to dewater, and then discharged the water after chlorination. Relatively, designed effluent quality is stable and achieve the primary standard of " comprehensively discharged standard of sewage in Liaoning province" (DB21/1627-2008). This paper introduced the technological process and main structure design parameters, the maintenance of membrane module as well as economic and environmental benefits analysis and so on of the sewage treatment plant.
