简要介绍了东营黄河三角洲主要纳污河流,并分析了河流的水质特征及部分水质离子含量高的原因;取5个河流断面样品,分析化学需氧量、铜、铅、镁、汞、六价铬、镉、砷、氰化物、挥发酚及油类含量,发现油类污染最为严重,超标率为100%。河流水质污染主要来源于采油、炼化,其等标污染负荷比分别为74.85%和17.36%;主要污染企业有5个,按等标污染负荷比对其进行了排序,提出了一系列水污染控制措施。

In this paper,main polluted rivers in Dongying delta areas have been introduced briefly,and river water quality characteristics and the origin of high ion contents have been analyzed.Choosing 5 river cross-section samples,chemical oxygen demand,copper,lead,magnesium,mercury,six chromium,cadmium,arsenic,cyanide,volatile phenol and oil content have been analyzed.It is found that oil pollution is the most serious.Its standard rate is 100%.River water quality pollution comes mainly from oil extraction and refining.Its pollution loads are respectively 74.85% and 17.36%,and main polluting enterprises are five.Based on these conditons,relative countermeasures are put forward to control water pollution.
