Research On Constructively Technology Of Water Supply Systems And Waterworks Sludge Reclamation In Small Towns Of China

Development of Small Towns is considered as a long-term urbanization strategy for China. Water supply facility is one of the necessary infrastructures for the small towns and is the significant foundation for sustainable economy development and improvement of local people's living standard. Furthermore, there are no pertinent regulations and standards for the construction of water supply systems in small towns in China, and scant of studies on different methods to construct water supply facilities and waterworks disposal and reclamation for various categories of small towns.To handle the problems mentioned above, this dissertation is based on on-site investigation, integrating practice into theories, combining existed regulations with innovative rules, employing research findings to practical situations, to serve as technical framework for constructive technology of water supply systems in various categories of small towns,ways of waterworks sludge disposal and reclamation, and had done the examination on waterworks sludge utilize for soil.Based on the understanding of features for small towns and corresponding water supply systems, modes of water supply systems in small towns are classified as regional water supply systems and independent water supply systems. It is strongly recommended that for conditional small towns, regional water supply is a better choice, and it better adopt unify water supply when independent water supply systems carried out. Then, major technologies aspects of regional water supply and independent water supply systems are studied, such as water demand prediction,water source rational deploy,water source protect,and pipelines construction,technology process etc. And combine the characteristic of samall towns, give some advises on the water supply system.Based on the waterworks sludge disposal and reclamation both here and abrosd, three system can used for sludge disposal and reclamation in small towns: separate disposal systems,unite disposal systems and associated disposal systems, major technologies aspects and requirements of the there systems are studied. Bring forward some ways of waterwoks reclamation in small towns: reclaim coagulator, used for structural material, used in refuse dump, utilize in soil etc, and it is strongly recommended that utilize for soil is a facility and energysaving way for most small towns.
