摘　　要：通过对天津市1000m3/d反渗透海水淡化示范工程及100m3/d海水淡化工程预处理部分的对比试验,得到不同海水水质的预处理效果对比数据。试验结果表明,新预处理工艺可将出水浊度降低至1NTU以下,总铁含量可降低至0.1mg/L以下。和原预处理工艺比较,新预处理工艺具有占地面积小、运行成本低、出水水质优等优点。Through comparing both preparation in the 1000m^3/d reverse osmosis seawater desalination demonstration project in Tianjin Municipality and the 100 m^3/d seawater desalination project, the contrast data ofpretreatment effect under the conditions of different seawater quality were acquired. It was showed that the new pretreatment process could make the effluent turbidity lower to 1 NTU or less, total iron content to 0.1mg/L or less, in comparison with the original pretreatment process, the new pretreatment process possesses the advantages of small occupying area, low operational cost and high quality effluent compared with the original pretreatment technology.
