预臭氧化与臭氧生物活性炭同步去除饮用水锰含量的研究

Study of Simultaneous Removal of Manganese in Portable Water with Pre-Ozonization and O-zone Biologic Activated Carbon

该文通过以流量为1m3/h,工艺流程为预氧化(预臭氧和预氯化)→常规处理→后臭氧生物活性炭→出水消毒的中试试验,阐明预臭氧化和臭氧活性炭工艺在保障各自效果的同时,取得了对锰有较好的去除作用,在1.5mg/L的臭氧投加量下,臭氧生物活性炭的深度处理工艺可以将锰含量降至0.02mg/L。

The pilot test of water treatment with pre-ozonization and ozone activated carbon, whose processing procedure is pre-oxidizing (pre-ozonization and pre-chlorination) normal treat post-ozone biologic activated carbon outflow sterilization under rate of flow 1m3/h, shows that the process not only plays the role of pre-ozonization and ozone activated carbon processes, but also has quite good action of removal of manganese. Ozone's dosage of 1.5mg/L will make the content of manganese decreased to 0.02mg/L if the polishing process with ozone biologic activated carbon is applied.
