江苏镇江焦化厂采用三氯化铁净工业用水,争化效果比原来提高46%,全年节水64.8万吨,节电6.5万度,节约费用3.2万余元。这个厂原来每年要消耗365吨碱式氯化铝净化工业用水,不仅净化效果差,而且费用大。去年上半年,该厂采用三氯化铁代替碱式氯化铝,工业用水的净化效果大大改善。经化验,水的混浊度由原来的15度下降到8度左右。由于水质提高,延长了水处理设备的运行周期,每班冲洗滤
The Zhenjiang Coking Plant in Jiangsu Province uses ferric chloride net industrial water, which has increased the effect of competition by 46% compared with the original. The annual water saving is 648,000 tons, saving 65,000 kWh, and saving over 32,000 yuan. This factory originally consumed 365 tons of basic aluminum chloride per year to purify industrial water, which not only had poor purification effect, but also cost large. In the first half of last year, the plant used ferric chloride instead of basic aluminum chloride, and the purification effect of industrial water was greatly improved. After testing, the water’s turbidity dropped from 15 degrees to 8 degrees. Due to the improvement of water quality, the operating cycle of water treatment equipment is prolonged, and each shift is filtered
