摘　　要：取水水质是影响海水淡化成本的重要因素之一,根据2007年5月、8月和11月3个航次的调查数据,对胶州湾湾口海域海水水质进行了分析。结果表明,除个别近岸站DIN超过二类海水水质标准外,pH、DO、COD、Cu、Zn、油类、PO43--P等指标均符合二类海水水质标准,SS、TDS含量较低,Ca2+、Mg2+含量低于湾内,该区海水可作为淡化取水水源,预处理工艺中应关注钙、镁、铁和锰的影响。The water quality is an important factor affecting the cost of desalination.By analyzing the data of sea water quality at the entrance of Jiaozhou Bay obtained in May,August and November of 2007,the results showed that most factors,including pH,DO,COD,Cu,Zn,Petroleum Hydrocarbon and PO43-P,fit the standard of Grade Ⅱ of Sea Water Quality Standards,except DIN at some coastal stations.The contents of SS and TDS were low.The contents of Ca2＋ and Mg2＋ were lower than those in the Bay.This area can be used as the intake source of desalination.The water pretreatment process should pay close attention to the effect caused by Calcium,Magnesium,Iron and Manganese.
