我厂位于长江口,每年11月至次年4月受到海水倒灌的影响。期间,电厂补给水处理所用原水改用深井水。但是,我厂两口深井含铁都较高,一号井含铁1.5毫克/升左右,2号井含铁9.1毫克/升左右。由于深井水含铁量远远超过了电渗析器进水水质要求(国内一般以小于0.3毫克/升为标准),这给生产上带来了许多不利因素。从79年11月起,至81年12月,曾先后三次因用深井水造
Our factory is located in the mouth of the Yangtze River and is affected by seawater intrusion from November to April each year. During the period, the raw water used for the power plant’s make-up water treatment was converted to deep well water. However, the depth of iron content in the two deep wells of our plant is relatively high. The number of irons in the No. 1 well is about 1.5 mg/l, and that of the No. 2 well is about 9.1 mg/l. Because the iron content in deep well water far exceeds the water quality requirement of the electrodialyzer (usually less than 0.3 mg/l in China), this has brought many unfavorable factors to production. From November 1979 to December 2014, it was used three times for deep well water
