Embodiment 1
[0033] The invention provides a method for adding chlorine to secondary water supply and storage equipment, such as figure 1 As shown, the equipment or devices used in the supplementary chlorine method include a stock solution storage and sampling device, a dilution dosing device, a monitoring device and an intelligent controller 1 . The stock solution storage sampling device comprises a stock solution storage tank 3, a storage tank water level switch 4 and a sampling assembly, wherein the sampling assembly includes a sampling tube 5 and a sampling pump 6 arranged on the sampling tube 5; the dilution dosing device comprises a first dilution tank 7, a Two dilution tanks 8, water adding components, liquid adding components and dosing components, the first dilution tank 7 and the second dilution tank 8 are equipped with a water level switch 9 and an agitator 10 in the dilution tanks, and the water adding components include a water adding main pipe 11 and a water adding pump 12.

Embodiment 2
[0052] On the basis of Embodiment 1, this embodiment is further described in conjunction with specific data, assuming that the volume of the managed water tank 2 is 5*3*2=30m 3 , the horizontal longitudinal section area is 5×3=15m 2 .
[0053] Specifically, in the step S1, a low-range online residual chlorine meter is used to monitor the residual chlorine concentration of the tap water in the water tank 2 in real time, and the residual chlorine safety value is set to 0.15 mg / L. The residual chlorine concentration of the tap water is reduced to 0.15 mg / L, so the intelligent controller 1 starts to add chlorine to the tap water in the water tank 2.
[0054] In the step S2, the sensor for detecting the available chlorine content of the sodium hypochlorite stock solution is a high-range on-line sodium hypochlorite detector 23 specially used to detect the available chlorine content of the high-concentration sodium hypochlorite stock solution. The usual sodium hypochlorite detector ...
