【摘要】：玉溪研和工业园区是云南省省级重点工业园区,昆曼高速公路(昆明-曼谷)、玉蒙高速公路、泛亚铁路东线、中线、昆玉铁路均在研和交汇,是云南连接东南亚、南亚重要的物流、交通枢纽,根据玉溪研和工业园区规划,今后片区将发展成为千亿级的工业园区,片区开发规模及污染负荷将会加大。研和地区四面环山,地形较为特殊,片区仅有歪者河为唯一地表水出水通道,研和片区地表水均汇入歪者河,使得歪者河成为研和地区主要的纳污水体。近年来歪者河水质呈下降趋势,现水质已不能满足环境功能要求。因此,地表水环境是片区发展的重要环境制约因素之一,如何控制研和地区水污染物,改善歪者河河流水体水质,是解决研和地区地表水环境同地区发展之间矛盾的关键。本论文通过对研和地区基础资料的调查分析,得出了歪者河现污染来源主要来自农业源和生活源结论。歪者河作为研和纳污河流,研和地区工业源、生活源、农业源的排放直接影响到歪者河的水质,现研和水污染治理基础设施不足,使得河流水质不断下降。今后研和开发力度的加大,污染负荷将进一步加重,因此研和应实施工业废水“零排放”,加快城镇污水处理基础设施建设,在河道两侧划定“禁养区”, 采取严格的水污染控制对策,控制水污染物进入歪者河,并通过河岸、河道整治等逐步改善歪者河水环境。
[Abstract]:Yuxi Yanhe Industrial Park is a provincial key industrial park in Yunnan Province. Kunman Expressway (Kunming-Bangkok), Yumeng Expressway, Trans-Asian Railway East Line, Middle Line, Kun-Yu Railway are all intersecting with each other. Yunnan is connected to Southeast Asia. An important logistics and transportation hub in South Asia, according to the Yuxi Research and Industrial Park plan, the area will be developed into an industrial park of 100 billion in the future, and the development scale and pollution load of the region will be increased. The Yanhe area is surrounded by mountains on all sides, and the topography is relatively special. Only the crooked river is the only outlet channel of surface water in the region. The surface water of Yanhe region is all confluence into the crooked river, which makes the Yanhe river become the main water body of Yanhe area. In recent years, the water quality of the river is declining, and the present water quality can not meet the requirements of environmental function. Therefore, the surface water environment is one of the important environmental constraints for the development of the region. How to control the water pollutants and improve the water quality of the river is the key to solve the contradiction between the surface water environment and the development of the area. Based on the investigation and analysis of the regional basic data, this paper draws the conclusion that the sources of pollution mainly come from agriculture and living sources. As the river of research and acceptance of pollution, the discharge of industrial source, living source and agricultural source directly affects the water quality of the river. The water quality of the river is declining because of the insufficiency of the infrastructure for water pollution control. With the intensification of research and development in the future, the pollution load will be further aggravated. Therefore, the research and development should implement "zero discharge" of industrial wastewater, speed up the construction of urban sewage treatment infrastructure, and designate "no-maintenance areas" on both sides of the river channels. Strict water pollution control measures should be taken to control the water pollutants entering the crooked river and gradually improve the environment of the crooked river through river banks and river regulation.
