Application Abstract: Aiming at different objects and characteristics of urban domestic water usage,the researches were systematically carried out and the demonstrate projects were being established according to the"5R"system from three aspects of broadening source of water,reducing water expenditure and enhancing water management.In terms of products,we have developed one anhydrous flushing negative pressure urinal and one negative pressure seat/squat toilet.One conventional gravity flow toilet and negative pressure seat/squat toilet based on negative pressure adapter were also designed.Besides,one set of negative pressure pipeline adapter and two kinds of compact negative pressure collector were also produced.In terms of technology,the development of gravity flow and negative pressure interconnected transportation technology has been basically completed for the collection of black water/yellow water/miscellaneous drainage.At the same time,the nutrient recovery from black water by microbial fuel cell treatment and chemical enhanced flocculation assisted by high-load activated sludge process(HRAS)were studied.The water quality stability of grey water purified by MBR and BAF and reused for home toilet flushing was also studied.The technology of using modified sawdust to construct composite soil surface layer to reduce runoff rainwater pollutants was studied.The effects of storage materials on biological safety during rainwater storage were studied.The effect of integrated non-dynamic cyclone sedimentation membrane filter reactor on rainwater treatment was also studied.Furthermore,based on the selection of reclaimed water source,the efficiency of treatment process,the stability of transportation and distribution system and terminal water storage,the differences of water quality characteristics of different reclaimed water sources are clarified.The adaptability of different types of water sources in reclaimed water treatment process is evaluated.The water quality stability of different pipeline transportation and distribution systems and the changes of water quality in the process of terminal water storage of reclaimed water are clarified.In addition,the use of water-saving appliances was investigated,the characteristics of multi-source water quality,water quantity and balance between supply and demand were analyzed,and the concept and calculation formula of integrated linkage water price system were put forward.The basic framework of water-saving e
