| Research Domain：Advanced oxidation technology |
Country：[CN] |
| Research Production： |
Advanced oxidation technology has been studied for purification and treatment of wastewater. Heterogeneous photocatalytic oxidations are currently being investigated to destroy refractory pollutants in water. Our efforts are concentrated on fixing TiO2 on various porous material, such as silica gel, Al2O3 and so on, improving catalysts and promoting the application of photocatalysis to wastewater treatment.
Using solar as the main power to save the cost of treatment process.

| Research Domain：natural waters and water processing undergo chemic |
Country：[CN] |
| Research Production： |
Chemical contaminants in natural waters and water processing undergo chemical and biochemical processes such as transformation, degradation, association or aggregation, adsorption, excretion and assimilation. Toxicity and toxicology of the contaminants or their intermediates depend heavily on these processes, which determine the quality of water. Research on the chemical forms of contaminants in aquatic environments and the toxicology associated with different chemical form is therefore the basis of ecological risk assessment of chemicals. Recent work include the development of innovative methods for chemical speciation and of bioassay, the case studies to elucidate relationship between abiotic process in aquatic multimedia and toxicity variations, as well as development of new approach for the application in the field of ecological risk assessment.

| Research Domain：The biological reactors for wastewater treatment |
Country：[CN] |
| Research Production： |
The biological reactors for wastewater treatment have long been dealt with as a black box, and their design has been mainly based on experiences. On the other hand, although many biological wastewater treatment processes have been developed and applied, bacteria have remained to be the dominating microbes responsible for organic degradation. In order to realize the bioreactors from the microbial aspects, microbial community analysis in bioreactors is conducted using some molecular biological techniques such as quinone analysis, FISH, PCR-DGGE, 16S rDNA gene clone and sequence analysis. Such information will be useful for the proper design and operation of wastewater treatment bioreactors. In order to topple some tough environmental problems, we focus on finding and utilizing the environmental functions (biodegradation and biosorption) of fungal microbes. Fungi including yeast and mold are employed for treating wastewater and their applicability is under investigation.
