复合电磁场处理污水试验及效果评价

Test and effect evaluation on hospital sewage treated by electromagnetic fields

摘要:
目的探讨污水经复合电磁场处理后能否回收利用.
方法以污水中水质较为恶劣的医院污水为对象, 用复合电磁场对其进行处理, 检测处理前后各项水质指标, 并把处理后水与生活日用水水质标准进行比较.
结果处理后水的总大肠菌群为0cfu/L, 各理化指标除化学耗氧量(COD)外, 均达到生活杂用水水质标准的要求.
结论污水经一定的预处理, 再用复合电磁场系统进行净化后, 可以达到回收利用的水质要求.

Abstract:
Objective To study whether sewage treated with electromagnetic fields can be reused or not.
Methods Various water quality indicators of sewage before and after treatment were detected.Indicators of treated water were compared with those of the Domestic non-drinking Water Quality Standard.
Results All indicaters of treated water except COD met the requiremnet of the Domestic Non-drinking Water Quality Standard.
Conclusion Sewage treated beforehand and clarified with compoud eletromagnetic fields, can get the demand that can be reused.
