Dr. Wu’s research focuses on the theory exploration and technology development of the water and wastewater treatment, aquatic environment pollution control (including biological purification, biological remediation) and environmental biotechnology. 
In the recent 10 years, he has served as PI (Principal Investigator) for 4 Natural Science Foundation of China, NSFC)projects, 3 National High-tech R&D Programs of China (863 Program) projects, 3 National key technology development projects, 2 National S&T Major Project and 1 international cooperative project. Based on the urgent problem of the eutrophication in China recent years, he developed the advanced water treatment technologies by combining the modern materials technology and biotechnology, which includes denitrification technology, ecological wastewater treatment technology applied for the non-point source pollution control, and biological purification technology of aquatic environment. Molecular biological study of the microbial population distribution in the water treatment system has also been carried out to understand the pollutant removal mechanism. 
Based on the background of the eutrophication problem in China, he expanded the study on the solid carbon source for biological denitrification to achieve good nutrient removal effect. He developed more than 40 new granular and aquatic plant shape like solid carbon, which play a good performance to enhance the denitrification rate up to 90%. He introduced the multi-soil-layer treatment system as an advanced technic to support the national lake nutrient (nitrogen and phosphorous) pollution control. By using step feed, adding solid polymer as carbon source and multi-media screening to fix phosphorus, both pilot scale and engineering scale MSL showed good performance on both pollutant removal and at the same time setting up a green environment surrounding. Beside the study on wastewater treatment, he also draws many efforts on drinking water purification technology.
His another research interest is algae control technology exploration, including algae control by biological way (such as lysing algicidal bacteria, algal viruses inhibiting algae, protozoa eating algae), algae control by enhanced biofilm, and algae control mechanism by straw produced in agriculture process. 
In engineering applications, he designed over more than 20 water treatment systems recently, including pharmaceutical wastewater treatment, dyeing wastewater treatment, aquaculture wastewater treatment, slaughter plant wastewater treatment, brewery wastewater treatment, urban and rural sewage treatment, landscape lake water treatment, and polluted source water treatment to achieve water supply safety.
