Xiaodong WangPhD candidate

E-mail: keddy4546@163.com

Education
Bachelor of Science in water and wastewater engineering
Master of Engineering in municipal engineering

 

Interest
Biological wastewater treatment, nutrient recycling, activated sludge, nitrogen and phosphorus removal, flocculation and sedimentation

Research background
* A composite ferric enzymatic activated sludge method to enhance biological nitrogen and phosphorus removal (project funded by National Science Foundation of China (NSFC))
* Seasonal variation of activated sludge settleablility in full-scale wastewater treatment plant and approaches in sludge bulking control (project funded by application and fundamental research project of Qingdao)
* Optimization of aeration system and energy consumption in municipal wastewater treatment plant (project funded by international cooperation project between China and Germany)
* Optimization of MSBR process in a full-scale wastewater treatment plant in Qingdao

Project title (PhD)
Optimisation of process control in wastewater treatment with real-time monitoring and control

Project aim
Developing a concept for a process control module covering both biological and chemical unit processes of a WWTP enabling full automation and increased process performance via real-time dosing control system.

Project description
Real-time dosing control is an approach which can increase the efficiency of wastewater treatment.This PhD research will expand the application of real time control concept to biological processes for removal of organic matter and nitrogen. The ambition is to develop a concept for a process control module covering the both biological and chemical unit processes of a WWTP enabling full automation and increased process performance. The study will provide a border understanding of process mechanisms and elaborate also the possibilities to function in harmony with sewer systems which will be a part of holistic optimization of sewerage systems.
