肇庆市地表水环境状况及水环境容量分析

AN ANALYSIS OF THE SURFACE WATER CONDITIONS AND WATER ENVIRONMENTAL CAPACITY IN ZHAOQING CITY

详细分析了肇庆市地表水污染状况及水环境容量。肇庆市地表水资源丰富,水环境污染属轻度污染水平,大部分地区符合国家水质标准类。肇庆市地表水环境容量丰富,但污染物的排放有逐年增加的趋势,污染物排放量已接近广东省总量控制水平。控制水环境污染是城市发展和城市规划的主要任务,提出了对水环境污染控制的措施,为城市规划提供依据。

Zhaoqing City is situated in the West and North River basins where there are water sources for the Zhujiang River Delta. The city is well-known in tourism. Under the new economic development situation, Zhaoqing City is undergoing a new cycle of conceptual and detailed urban planning. To meet the requirement of the planning,an analysis of the surface water conditions and water environmental capacity of the city is made in the paper. It is shown that the resource of the surface water in Zhaoqing City is rich and its water environmental pollution is at a low level. In most areas the water quality is of Category II in the national water quality standard. Although the water environmental capacity is high, the pollutants in the drained wastewater have taken an annual-increase tendency-the volume of wastewater emission is reaching the total control level of Guangdong Province. To control water environmental pollution is a major task for the metropolitan development. The methods of controlling water environmental pollution in Zhaoqing City, are discussed.
