Abstract:

Based on the problems including Low C/N ratio, low efficiency of phosphorus removal, poor operation performance during the process of upgrading and reconstruction of wastewater treatment plants, the project aimed at improving wastewater treatment efficiency, reducing system energy consumption, meeting effluent water quality standards, enhancing the comprehensive control of carbon and nitrogen in wastewater treatment plants, biological nitrogen and phosphorus removal technology, improving the techniques of water quality ecological protection for effluent biological and chemical treatment, and complete equipment for wastewater recycling. Furthermore, based on the problems of high water content, unstable sludge, secondary pollution by organics, microorganism and heavy metal of urban wastewater treatment plants, the project aimed at improving the techniques including dehydration pre-treatment and high-efficient enhanced dehydration of sewage, developing technology and complete equipment for sewage resource utilization. The project provided technology support for point source reduction of urban sewage and presented examples for upgrading and reconstruction of wastewater treatment plants in large-scale in the Weihe river area.
