Research overview:
1) To study means of the efficient treatment of nutrient salt groups including phosphorus and nitrogen and organic polluting substances, 2) To study conditions for the efficient purification of lake and river water fouled by the proliferation of musty odor algae and algae with harmful substances and of sea water polluted by the abnormal growth of the red tide, 3) To study methods for the breakdown and elimination of difficult-to-breakdown substances contained in the industrial waste water, water from the reclaimed land and water from contaminated soil by biological, physical or chemical means, 4) To develop a method, by gene manipulation, cell culturing and others, for locating and culturing on a large scale useful microorganisms that can be used to help improve water quality and clean up the polluted sludge, 5) To study means to develop a method for controlling the growth of useful and harmful microorganisms, which is essential in keeping high quality in our water environment, 6) For the treatment of wastewater and sludge, to develop a biological, physical and/orchemical method that produces less CH4, CO2 and other gases considered to the main cause of the earth's warming
