光催化深度水处理工艺设备在泳池水消毒中的示范应用

Demonstration and Application of Technological Equipments of Photocatalytic Advanced Treatment in Water Disinfection for Swimming Pool

采用自主开发的8英寸管式光催化组件,设计制造光催化深度水处理工艺设备,并与常规氯消毒组合处理泳池水,当游离性余氯质量浓度由0.8 mg/L降至0.4 mg/L,消毒剂投加量下降40%,pH调节剂投加量下降25%时,示范试验证实菌落总数、总大肠菌群、pH、氧化还原电位(ORP)和浑浊度等各项指标符合《游泳池水质标准》(GJ/T 244—2016)所要求的指标。该设备与常规氯消毒组合处理泳池水时,运行稳定,泳池水品质显著提高,在泳池水质要求较高的场所具有良好的应用前景。

The self-developed 8-inch tubular photocatalytic module is used to design and manufacture photocatalytic advanced treatment equipment,which is combined with conventional chlorine disinfection to handle the pool water.When the free residual chlorine is adjusted from 0.8 mg/L to 0.4 mg/L,the dosage of disinfectant is reduced by 40%,and the dosage of pH regulator is reduced by 25%.The demonstration tests find that the total number of colonies,total coliform group,pH,ORP,turbidity and other indicators meet the requirements of Water Quality Standards for Swimming Pool(GJ/T 244—2016).When the equipment is combined with conventional chlorine disinfection to treat the pool water,the demonstration equipment runs stably and the quality of swimming pool water has been significantly improved,so it has a good application prospect in places with high swimming pool water quality requirements.
