| 摘 要： | 利用连续处理高浊度海水试验,比较了舰艇反渗透海水淡化预处理系统分别采用气水在线双洗和药剂加气在线清洗时,滤过水SDI、浊度以及系统跨膜压差的变化趋势。结果表明,两种在线清洗方法都能够使系统滤过水SDI≤5、浊度≤1.0 NTU,达到舰船反渗透海水淡化装置的进水水质要求;但药剂加气在线清洗系统滤过水SDI多介于2.0～2.5之间,浊度≤0.75 NTU,系统跨膜压差≤43 kPa,波动范围较小,变化趋势平缓,更有利于舰船反渗透海水淡化膜法预处理系统的稳定运行。

| Abstract: | The air-water and aerated chemical cleaning online technology were adapted respectively to the membrane pretreatment system for seawater reverse osmosis system(SWRO)of ship in treatment of high turbidity seawater.The long-range variation trend of turbidity,silt density index(SDI)of the filtrating water and trans-membrane pressure(TMP)were investigated in this paper.The experimental results showed that turbidity in treated water by the two methods above mentioned was less than 1.0 NTU,SDI as low as 5;the rel... |
