Hazardous wastes are substances with toxicity, inflammability, chemical reactivity, infectivity and radioactivity, which make hazardous wastes the potential pollutants harming to the atmospheric, aquatic, edaphic and other ecological environments. Along with the development of society and living level, utilization of land and resources, and sharp growth of urban population, the amount of hazardous wastes rises greatly which continuously causes eliminativeless impacts on ecological environment, resulting in potential damage to human health because of their characteristics. Therefore, hazardous wastes not only pollute the urban environment but also retard the realization of sustainable development. The enforcement of management system of urban hazardous wastes has great values on the economy development, environment protection and peoples’ health.
      In this paper, the overall process management theory and systematical analysis were adopted to realize the design of overall process management system on the urban HSW, based on the management principles of overall process of hazardous wastes including yielding, collection, transportation, utilization, storage, treatment and final disposal, as well as the three main principles of reducing, recycling and innocuity.
      In this study, the present situations and developing trends of hazardous wastes management, treatment and disposal were carefully analyzed. Then according to the overall process management theory, with the systematical analyzing method, the technical plan of hazardous wastes disposal and the hazardous wastes management system were established after each step analyzed. Taken Fujian Province as an example, the treatment and disposal of hazardous wastes were studied systematically. By the analysis on the risk factors of hazardous wastes disposal process, the study assessed the social and environmental risk, and put forward environmental management countermeasures, which was important to the theoretical and practical aspects of the urban hazardous wastes management system.
