摘　　要：循环冷却水存在COD超标、磷含量偏高等问题,造成了换热设备结垢、腐蚀。采用生物制剂进行处理,提高了循环冷却水的水质指标。运行结果表明:生物制剂代替化学药剂后,循环冷却水的COD、氨氮、氯离子和总磷含量明显降低,去除率分别达到92%、95%、57%和73%,处理效果良好。补充新水由30%降至10%,能够显著减少污水排放量和磷排放量,具有较好的经济和社会效益。There are high content of phosphorus and COD,exceeding the standard in recirculating cooling water system,which is prone to cause scaling and corrosion of heat exchange equipment.Therefore,biological agents is used to improve the quality of recirculating cooling water.The results shows that the contents of COD,ammonia nitrogen,chloride ion and total phosphorus have decreased drastically,the removal rates reached 92%,95%,57%and 73%respectively.It is important that the discharge of sewage and phosphorus significantly decreased,and the proportion of make-up water decreased from 30%to 10%,a good economic and social benefit is achieved.
