粤西某市小容量河流水污染综合控制研究

对粤西某石化城河段几种主要污染物进行了容量计算 ,发现即使工业污染源全部达标 ,其水质状况与目标的差距仍较大 ,据此提出小容量河流的观点。为保护水环境 ,结合流域实际情况 ,本文提出改变以往单纯依靠工业污染源达标控制手段 ,而采用多手段相结合的综合管理模式来改善水环境的观点 ,并以中长期水环境规划年内目标值为依据 ,分析了本方法的有效性、经济性和可操作性 ,由此对其他具相似条件小容量河流的城市水环境管理起到借鉴性作用。

Study on the water pollution control of an extremely low capacity river in a pertrochemical industry city, western Guangdong Province

The paper deals with the capacity of major pollutants of the river of a pertroleum-city in the west of Guangdong Province. Results indicate even though all industrial sources are controlled under the discharge standard of water pollutants, present water quality is far from the goal of water quality due to the extremely low capacity. To protect water environment, the paper analyzes all parts of water management means used in this specific area, and it is hoped that a reference management model will be proposed and applied to other similar urban rivers.
