The Research Group of Biotechnology for Water Pollution Control

Group Leader: Wang Aijie Laboratory: Key Laboratory of Environmental Bio-Technology,CAS

The Research Group of Water Pollution Control Biotechnology 

  Dr. Aijie Wang obtained her Ph.D. degree in environmental engineering from Harbin Institute of Technology in 2000. She is the recipient of several national academic awards, which include Distinguished Professor of Yangtze River Scholar (MOE of China) and National Outstanding Youth Science Fund (NSFC). She has been selected by the Youth Science and Technology Innovation Leadership (MOST of China). In 2015, she has been elected as a Fellow of International Water Association. Professor Aijie Wang is the head of Key Laboratory of Environmental Biotechnology, RCEES, CAS. She is on the editorial board of several reputed journals, such as Sci. Rep. and Appl. Environ. Microbiol. Meanwhile, she also serves as the Deputy Director of IWA AD China Chapter and has been on the panel of another two Clusters of IWA. Dr. Aijie Wang focused her research on biotechnology for water pollution control. She developed the theory of microbial process optimization and control, proposed the principle for directional biotransformation of refractory pollutants, formed a series of innovative wastewater treatment technologies, and realized full-scale applications of such technologies. She has published more than 200 peer-reviewed papers and 3 monographs. In addition, she has drawn up 1 China national standard and been granted 40 Chinese patents. Her research achievements have been recognized with multiple awards, which include three National Science and Technology Progress Awards in 2004, 2007 and 2010, China Industry-Academic Cooperation and Innovation Award in 2015. She has advised more than 90 Post-docs and graduate students.

Enhanced Biotransformation of Toxic Refractory Organic Compounds in Wastewater 

Hao-Yi Cheng, Bin Liang, Xue Xia, Wen-Zong Liu, Ai-Jie Wang* 

  In China, we urgent need to enhance the treatment capacity and efficiency of wastewater from industrial parks. A preferred solution is the bio-based technology due to its high efficiency and low energy consumption. However, the pollutants from industrial sources are toxic, complex in structures, refractory to biodegradation and hard to be removed stably, which result in the low treatment efficiency. Our group has established strategies (for directional regulation of microbial respiration activities) that could accelerate the biodegradation of pollutants, and constructed engineered system that has built-in electrode based on the regulation strategy and optimized process system. By introducing electrodes into the anaerobic system, we have discovered that the directional regulation strategy can enhance the biodegradation rate of nitroaromatic, halogenated and heterocyclic antibiotics. For the biodegradation of aromatic amines, we found that the introduction of anode can activate the microbial metabolism pathway of aromatic amines, which makes the mineralization of aromatic amine does not completely depend on the oxygen as the electron acceptor, and aromatic amines mineralization can be achieved at very low levels of dissolved oxygen (such as <0.1mg/L), and greatly reduced energy consumption of wastewater treatment. Through pilot scale study, we systematically investigated the treatment efficiency of core process. This study provides an important theoretical guidance and technical support for wastewater treatment to meet the emission reduction and recycling.
