Water circulation disinfection system and water quality control method

The invention provides a water circulation disinfection system and a water quality control method, the water circulation disinfection system comprises a circulation water pipeline, one end of which is communicated with an external water supply system; the at least one water using end assembly is communicated with the circulating water pipeline; the automatic sterilizing device is communicated with the circulating water pipeline; the water quality monitor is communicated with the circulating water pipeline; the pumping part is arranged on the circulating water pipeline; and the control device is electrically connected with the automatic sterilizing device and the water quality monitor. According to the water circulation disinfection and killing system, the time for judgment is shortened, so that the water quality detection efficiency is improved. Meanwhile, the water in the circulating water pipeline is pumped through the pumping piece, and the automatic disinfection device is started for disinfection. Therefo
