The invention discloses a water quality self-inspection type ozone wound treatment instrument. Tap water is directly connected with an inlet of a filtering device, preliminary filtration is conductedthrough a filtering cavity, filtration is conducted through a reverse osmosis device, pure water is preliminarily obtained, the filtered pure water is pressurized by a pressurizing pump, filtration isfurther conducted by using an EDI device to obtain pure water with higher purity, the pure water enters a water storage pool and flows into an electrolytic tank through a pipe fitting for use, the electrolytic tank separates an anode pool and a cathode pool by using a partition plate, the electrolyzed hydrogen and ozone are separated and are not mixed, and the purity of the ozone is improved; a water quality detection instrument is provided, so that the use water quality is monitored and the practicability is enhanced; a one-way valve is provided, so that backflow of water in the electrolytictank is avoided; part of the ozone is dissolved into the water, so that inaccurate monitoring result caused by backflow is avoided; the ozone has corrosive effect after being dissolved into water, socorrosion to the water quality detection instrument is avoided; when the water quality does not accord with the standard, exchange is facilitated after joint connection through exchange of the tap water filtering device.
