离子交换与吸附

通过对煤化工企业进行深度对标和数据分析发现，两企业单位烯烃产品取水量分别为26.03 t/t和23.5 t/t，差距为2.53 t/t (9.7%)，总用水量相差5%。取水源不同造成原水离子等污染物浓度差距较大，电导率和氯离子浓度分别相差41.3%和83.1%，除了原水水质较差的原因外还有全年烯烃产品量相差近17%，也是单位耗水成本较高的原因。文章根据对标结果对该企业用水情况进行了分析评价，提出了节水措施和水处理建议。

The deep benchmarking and data analysis of coal chemical enterprises were conducted. The water intake of olefin products per unit of the two enterprises was 26.03 t/t and 23.5 t/t respectively, with a gap of 2.53 t/t(9.7%). The difference of total water consumption was 5%. Due to the different water intake sources, the pollutants such as ions in raw water is much different. The difference in the index of conductivity and chloride ions concentration were 41.3% and 83.1%, respectively. Except for the poor water quality of raw water, the difference of the olefin production in the whole year was nearly 17%, which is also the reason of high unit water consumption cost. According to the results, the water usage situations of the enterprise was analyzed and evaluated, and water-saving measures and water treatment suggestions were put forward.
