摘要
在聚甲醛装置循环水系统应用电化学处理技术,在pH不变的情况下,循环水浓缩倍数提高了 1 倍,循环水总硬度和钙硬度保持不变,循环水碱度则从 925 mg/L降低到 475 mg/L,大大降低了循环水结垢几率;循环水浊度从 3.12 FTU降低至0.92 FTU,降低了排污水流量,循环水补水量从 100 t/h减少至80 t/h,节水率达 20%以上,年节约水资源费用约 30 万元;循环水化学药剂用量大幅降低,年节约药剂费用约15 万元.
Abstract
This paper introduces the circulating water system and electrochemical treatment technology of polyoxymethylene(POM)plant.The application of electrochemical treatment technology in circulating water system reduces the make-up water amount and sewage discharge of circulating water system,reduces the amount of reagent used in the circulating water treatment,reduces the scaling rate of heat exchanger in circulating water system,improves the long-term heat exchange efficiency,and stabilizes the production.Results show that after electrochemical treatment technology is used,the concentration ratio of circulating water increases by one time,and the total hardness and calcium hardness of circulating water remain unchanged when the pH of the circulating water remains unchanged.The alkalinity of circulating water decreases from 925 mg·L-1 to 475 mg·L-1,which greatly reduces the probability of scaling in circulating water.The turbidity of circulating water declines from 3.12 FTU to 0.92 FTU,which reduces the flow of sewage.The make-up amount of circulating water decreases from 100 t·h-1 to 80 t·h-1,achieving a water saving rate over 20%,which saves about RMB 300 000 in annual water resource cost.
