| A district compound hospitals as essential infrastructure in urban construction plays a very important role for preventing and treating diseases, safeguard human health. But it will inevitably cause certain environmental impact during its construction and operation,. Therefore, it is necessary to analyze and assess the environmental impact of district-level compound hospital construction project. Through theoretical research and example analysis, this paper has given a systematical analysis on the environmentak impact of a district-level compound hospital construction project, and the following regulations have been found.(1) During the construction of a district-level compound hospital, main pollution sources are construction dust, construction machinery exhaust, construction wastewater, soil erosion at the construction site, construction noise and the construction waste material etc. The main pollution sources are hospital medical wastewater and medical solid wastes during the period of the hospital operation.(2) The experience coefficient method may be applied to estimates the amount of TSP contributed by construction site and vehicles dust during the construction. Hence, some practical measurenet should be adopted to reduce those pollution affects, such as adopting construction site sprinkler or installing windscreen fence to redunce wind speed in order to control cpnstruction dust. Also, the construction wastewater may be estimated by the experience coefficient method, and it must be pre-treated through precipitation. Construction noise is mostly from construction machinery operation, should avoiding night construction.(3) During decorating, the main environmental pollution factors include:the bad smells from fitment plank stuff, the organic waste gases from binder, the dust and noise during decorating and solid waste such as plank corners waste products.(4) During hospital operating period, solid wastes include medical wastes, spent oil from the back-up generator and from dining room, sledage from the wastewater treatment station and living garbage. The first four belongs to dangerous solid waste according to hazardous waste management, transferred and assigned to dangerous waste disposal qualification of units for free-pollution disposal.(5) The environmental risk of the hospital project behaves as effluent of raw wastewater, medical wastes, leakage and losses of the exhaust from the special regional negative pressure area, which may cause bad effects on the environment and human health. Main risk causes are human elelments. After taking a series of control measures, leakage and accident loss can be effectively reduced, and once happened, the consequences can be effectively controlled.The Guangzhou LuoGang Center Hospital construction Project has also been taken as an example to analyze the environmental impact assessment in this paper. The research results of this paper could be referenced for similar construction project of the hospital environment impact assessment.
