temperature controller 4, and electromagnetic valve 8 and temperature controller 4 are connected with reactor 5.The generation system is the special equipment of pressure piping disinfection of drinking water, and water pipe pressure can be used under 0.7MPa.It has the characteristics of conversion rate of chlorine dioxide is high, equipment operating cost is low, easy to operate, control level is high.Its main technical parameters：Dosing pump 1 and one 12 maximum working pressure (MWP) of dosing pump are 0.98MPa；Dosing pump 1 and one 12 electrical power of dosing pump are 24W；Dosing
