| With the fast development of economy, enhancement of people's standard of living, increasing of urban population and speedup of urbanization, the generation of municipal solid waste (MSW) has heavily risen, the elements of MSW have changed. This not only brings a great harm on urban environment, but also hinders urban economic growth. My paper first time quotes source separation MSW collection system in Shenyang, controlling the quality of MSW from source, it is very crucial for the disposal and synthetic utilization to build MSW sorting collection system in order to reduce the quantity of MSW.In this paper, author researches the attitude and behavior about BMW source separation through 2005-2006 two questionnaire, assessing public participation rate and separation quality of BMW, investigating the quantity and composition of MSW , BMW and RMW by two collection techniques in Shenyang, comparing the physical and chemical characters, specially the compare of heavy metal and organic pollution in BMW and caloric value in RMW by two collection techniques.Investigations on the aerobic compost and anaerobic digestion biodegradability of household bioorganic waste in laboratory scale. The composting experiments use aerobic compost reactor designed by ourselves to treat with BMW, monitoring and control of process parameters during composting, investigating the biodegradability, analyzing the heavy metal and organic pollution in composting production, assessing the quality of compost; Batch digestion of source separation biological municipal waste (BMW) was carried out under 37°C for 50 days, investigating the biogas production character and the impact on biogas production efficiency by adjusting pH, assessing the biogas potentials and ultimate biodegradability of source separation BMW in AD, establishing the unitary linear regress model of Shengyang BMW biogas yield with TS and VS.
