在高压供水管道中投加二氧化氯消毒液，投加压力必须大于管道内压力。为防止管道腐蚀，二氧化氯浓度不能太高。高压输水管道一般用于输送生活饮用水，要求发生器有较高的化学转化率和获得高纯度的二氧化氯消毒。

It describes the process of adding ClO₂ disinfectant liquid to hig h pressure water- supplied pipes, in which the ssure of adding the liquid should be bigger than that of transporting water in the pipes.To prevent pipes from corrosion, the cont ent of ClO₂ should not be t oo high.H igh pressure water supplied pipes are usually used to transport drinking water for daily use, the generator should have high transforming rate in order to obtaina ClO₂ disinfectant liquid with high purity.
