520			_aPeople in DuongLieu community have diversified economic sectors to get better income sources and hence to improve their living standards. There are seven major economic sectors, including traditional production. These are rice cultivation, livestock, trading; starch and starch-based production namely, tapioca and arrow root starch production, glucose syrup and vermicelli production. The starch and starch-based production releases a large amount of wastewater characterized by a high BODs and a BODs to COD ratio always higher than 0.6. This wastewater should be treated by biological processes, and an anaerobic treatment seems the most economic. However, the wastewater is now being discharged without any proper treatment, so it is heavily polluting surround environment. The Leontief input-output model is introduced to investigate environmental economic effects of the starch and starch-based production. The community buys tapioca and arrow root from other communities to produce various products, and they mostly sell this product to outside. By using analyses of market variables, input-output flows in physical unit and in monetary value for all economic sectors are built up. The technical coefficient-direct requirement coefficient is used to arrange the matrix and then the inverse matrix is found. Basing on the inverse matrix, two scenarios of economic effectiveness development and environmental protection are analyzed. Under these scenarios, some alternatives with different final users-final demand are considered. Not only change of starch and starch-based would effect on pollutant output, but other change also. Trading is most important among seven economic sectors, it should be encouraged to develop. With given final users-final demand, set of total output of each economic sector would be determined. Pollutant output and appropriate wastewater treatment is planed as well. As a tool for analyzing and planning environmental economic structure, input-output model should be more utilized and studied.
