Suzhou Key Laboratory of Water Environment Science and Technology

  "Suzhou Key Laboratory of Water Environment Science and Technology" was established in 2007 by Suzhou Municipal Government, University of Science and Technology of China and City University of Hong Kong. It is a comprehensive environmental science and technology research and development platform integrating water pollution control technology research and development, achievement transformation, postgraduate training and social services. The laboratory has 20 professors, associate professors and other scientific research personnel, 5 postdocs, 35 graduate students. Laboratory team in recent years to undertake a number of provincial-level research projects, in wastewater treatment and recycling materials and technology, environmental pollutant monitoring technology and equipment of geochemical behavior, environmental pollutants and environmental effect analysis and other research has made a series of important achievements and carry out the engineering application, for ecological environment protection in China provides an important theoretical and technical support.

1. Representative research results

1.1 New materials and technologies for water pollution control/recycling

A series of nanometer adsorbents with high efficiency for adsorption and desorption of pollutants were prepared, which realized the efficient and selective enrichment of 

a variety of pollutants in the environment, 

and had a broad application prospect in water environment remediation. Based on conventional optimization design of photocatalytic materials and crystal control, 

advanced oxidation degradation of materials, developed a series of pollutant enrichment - developed optical/electrical catalytic degradation of pollutants new nanometer material and 

technology (FIG. 1, 2), and successfully applied in pesticide wastewater, printing and dyeing wastewater, landfill leachate, wastewater treatment engineering; In addition, 

new anti-pollution membranes based on new nano materials and micro/nano structures have been developed, including efficient water treatment membranes based on polymer crystal size 

regulation, anti-pollution microfiltration membranes modified by biological nano metal materials, etc., which have been successfully applied to a variety of wastewater treatment and deep 

purification. More than 60 papers have been published in journals such as Nature Protocols, Nature Communication, PNAS, and Angew, and 12 patents have been granted.

1.2 New materials and equipment for environmental pollutant detection

A series of highly sensitive photochemical and electrochemical sensors have been developed and successfully used for on-line detection of a variety of environmental pollutants (Fig. 3). 

Among them, the enhanced attenuation total reflection infrared spectrum analysis system based on the highly reflective waveguide material and superhydrophobic surface was developed. 

The detection sensitivity of organic pollutants is one order of magnitude higher than that of similar technologies, which has broken through the limitation that existing methods cannot be 

used for in situ analysis of complex pollutants with low concentration. A new technology for in situ analysis and monitoring of biofilms was established by using high-throughput optics to 

track the nanoscale vibration behavior of microorganisms at different interfaces at the single-cell scale and by developing in situ spectroscopic analysis of biofilms based on Tri-Villaman imaging 

and non-negative matrix factorization data analysis. In addition, the whole-process dynamic monitoring technology based on the in-situ analysis of the spectral fingerprint of pollutants and 

microbial metabolites has also been developed. Combined with the development and application of intelligent control, diagnosis and early warning technology and equipment, the refined 

operation level of sewage treatment plant has been significantly improved. More than 40 papers have been published in journals such as Nature Sustainability, Nature Protocols, PNAS, 

and JAS, and 9 patents have been granted.
