Study And Evaluation On Treatment Strategies Of MSW In Shanghai

With the rapid economic development and the overall rise of people's living standard, more and more MSW (municipal solid waste) are being made in life and in the process of production, which has become a social problem troubling urban development, polluting city environment and impacting on its citizen's daily life in Shanghai. It's an impeditive task to research on the disposition strategies of MSW which meet the sustainable economic development of the city.According to statistics of its total volume and analysis of ingredients of MSW in Shanghai in recent ten years, it bears the features containing higher percent of erosive and organic ingredients, lower percent of recyclable elements, fluctuating with change of seasons, higher hydrate and lower calorie, etc, compared that of developed countries. Hereby multivariate regression linear model and analogy analysis have been taken to predict the future volume and ingredients of MSW in Shanghai. It turned out that by 2010, the volume of MSW in Shanghai will reach17567.19 ton per day, the average amount of 1.28 kg per person per day, among which leftovers will take the first position.Here widespread survey of how MSW has been classified and collected in every district and county in Shanghai since its implementation of the policy about the classification and collection of MSW from 1996 has been carried out, and its results have been consolidated, raising some assumptions on establishing a system of classifying and collecting MSW in Shanghai in accordance with its current situation.In studying transportation and transfer system of MSW and describing its development, here overall evaluation has been carried on three types of transfer from technological, economic and social environmental points of view, and reached the conclusion that shoving-in package is the best choice. Considering the dominant and subdominant issues influencing the mode of receiving and transferrmg MSW. The research also took the method of clustering analysis to design the mode of receiving and transferring MSW and the relevant solution of logistics of MSW.Based on survey of current status of disposing MSW in Shanghai, the paper carried on an overall evaluation of three ways of disposing landfill, incineration and compost from three aspects of technological liability, environmental accordance and economic applicability. Frombalanced overall benefits, it proposed the conception and long-term plan of establishing the system of disposing MSW, "enforce and improve technologies of landfill, cautiously develop incineration technologies, fully emphasize on biological disposing technologies, tentatively explore new technologies of using energies, multiply follow the road of sustainable development."Through statistic analysis of stock site of MSW in Shanghai, by learning from the success of reforming landfill site in foreign countries, appropriate reforming plans for stock site along SUZHOU Creek, stock site in GU village in BAOSHAN, stock site in SANLINTANG and the first, second and third phase projects of landfill site in LAOGANG has been set up in the paper respectively based on floor space, timing and geographical location.The paper also analyzed the administration of MSW abroad and pinpointed the features and existing problems of administrative policies of MSW in Shanghai, and explored a brand new set of mode of administrating MSW in Shanghai from four aspects of updating concept of administration, improving laws and regulations, reforming policies and pushing overall decision.
