Research On Urban Residential Design Strategy Based On Organic Waste Microcirculation

With the rapid development of urbanization,urban linear nutrient metabolic problems,organic waste management confusion and nutrient resource shortages,more and more serious,due to the organic waste is rich in large amounts of nitrogen,phosphorus and other nutrients in resources,for a long time without organic waste to deal with the nutrients and the practice of direct emissions,not only causes a loss of nutrient resources,also make the pollution to the environment,thus explore a sustainable urban organic waste management strategy is particularly important.Focus on the medium and micro level of urban organic waste recycling,the city residential areas as the research object,through the organic waste microcirculation combined strategy and urban residential design,so that the organic waste as far as possible within the residential house or nearby areas for processing,and live in the area to introduce the medium of urban agriculture,the ecological technology will organic waste into organic fertilizers to reuse in the agricultural production.In this way,the nutrient resources in the waste are recycled,and the waste is transferred and digested in a minimum range,so as to reduce the loss of nutrient resources in the city and promote the nutrient metabolism model from linear metabolism to closed cycle.The paper is divided into six chapters.The first chapter is the introduction,which introduces the background of the topic,literature review,research purpose and significance,research content,methods and innovation.The second chapter analyzes the related concepts of organic waste,defines the research object,and expounds the urgency and necessity of the microcycle of organic waste and its relationship with urban agriculture.In chapter 3,on the basis of theoretical research,the data calculation is carried out by material flow analysis(MFA),and the nutrient flow in residential areas before and after the introduction of urban agriculture is compared and analyzed by taking nitrogen and phosphorus as index materials.Summarize and analyze the similarities and differences between single community self-absorption and multi-community joint treatment and their applicability.The fourth chapter analyzes the residential design strategy based on the micro-circulation of organic waste from the three aspects of space construction,technical system and management operation,and learns from the experience of foreign developed countries in the treatment of organic waste.Inthe fifth chapter,the research design is carried out,and the material flow analysis method is used to verify the above theoretical results.The sixth chapter is the summary and prospect part,which summarizes the research results,analyzes the shortcomings of the research and puts forward the future research direction.In this paper,the architecture and environmental engineering,ecology and other subjects,the combination of the knowledge of the integrated use of multiple disciplines,with the aid of material flow analysis to establish nutrient metabolism model of city residential areas,the introduction of urban agricultural organic waste management system,optimize the current city in order to design of sustainability of the urban residential house in China.
