荆门气温较高,一年里除冬季以外,春、夏、秋三季,在循环水场的凉水塔,水池的内壁及其它构筑物上,都滋长着各种藻类。近几年我厂虽然在循环水中投加了一定量的氯和洁尔灭等杀生剂,但对藻类的滋长抑制效果不够理想,为解决上述问题,我们于前年到齐鲁石化公司学习,回来后又进行室内试验探索,在取得一定经验的基础上,于去年三月份我厂大检修时,在三个循环水 Jingmen has a relatively high temperature. In addition to winter, in the spring, summer, and autumn, a variety of algae grow in the cold water tower of the circulating water field, the inner wall of the pool, and other structures. In recent years, although our plant has added a certain amount of chlorine and beryllium and other biocides to the circulating water, the inhibitory effect on the growth of algae is not ideal. To solve the above problems, we went to Qilu Petrochemical Company in the previous year to study. It also carried out indoor experiment exploration, based on certain experience, in the last three months when our plant was overhauled in March last year.
