摘要
对黄河小花区间水质环境调查的结果表明，入黄量最大的污染物是ＣＯＤＣｒ，它主要来源于老蟒河、伊洛河、新蟒河。采用《污水综合排放标准》和等标污染负荷法对调查结果予以评价的结果是，小花区间干流及支流的污染物以有机类为主，尤以ＣＯＤＣｒ和氨氮为最多。预测小花区间２００５年的工业废水排放量将达到２６１７０万ｔ，防治水污染已刻不容缓。
CODCr, realized as the most
dangerous pollution material from the investigation of water quality environment in the reach
between Xiaolangdi and Huayuankou of the Yellow River, mainly comes from Laomang river,
Yiluo river and Xinmang river.The Comprehensive Standards for Sewage Delivery' and the
method of equal standard for pollution load are applied for evaluation of the investigation
achievements. The evaluation demonstrates that the main pollution materials in the reach
between Xiaolangdi and Huayuankou are organic materials, especially CODCr, ammonia and
nitrogen. It is estimated that industrial sewage discharge in 2005 will be 261 . 7 million tons in
the reach. Therefore, it is urgent to prevent and harness water pollution immediately.
