摘要
为了研究黄河三门峡库区泥沙对化学需氧量(COD)的影响,在三门峡坝下、潼关和龙门3个断面取样,并按要求分别配制成清水、清浑水、浑水水样,测定相同水体加酸保存,相同水样的清浑水和清水,含沙量大于3kg/m3的清水、清浑水、浑水等水样的COD值。得出结论为:(1)三门峡库区黄河支流和枯水季节的干流,用CODcr测定能反映水体有机污染程度;(2)对于沙量大于3kg/m3的水体,清水CODcr浓度比较能够有代表性地反映水质有机污染状况。
In order to research the influence of Yellow River Sanmenxia reservoir area sediment to COD,this paper takes water from Sanmenxia Baxia,Tongguan,Longmen three sections,and obeys the rules to prepare clear,clear and silting and silting water samples.It tests the same water with acid,the clear and silting water and clear with same water sample,the COD values of water,clear and silting water,clear water with sediment concentration more than 3kg/m3.The conclusion is that 1.Use CODcr test to show the water organic pollution degree in the Sanmenxia reservoir area Yellow River tributary and dry season main stream;2.The clear water CODcr can show the water quality organic pollution situation typically to the water with sediment concentration more than 3kg/m3.
