The present invention relates to a high water purification treatment system, and more particularly, to a high water purification treatment system having an ozone inflow mixer and mixing means for dissolving ozone can improve the water purification efficiency of raw water.

The basic factors for human being to live depends greatly on the natural environment, social environment, physical environment, etc. Unfortunately, industrial development is accumulating factors that impair health by increasing environmental pollution and destruction. In addition, air pollution, water pollution, and soil pollution are destroying the natural rich dietary environment, which is detrimental to health.Solution of such problems is difficult to solve in a highly developed modern society, but a better natural environmental element indispensable to maintaining health. As one of the measures to create a better natural environment element, we are developing a water treatment system for humans to drink water with confidence, which will be described with reference to FIG. 1.

Raw water having passed through the auto strainer 3 flows into the micro filter 4. The micro filter 4 is formed of a cartridge type finely manufactured by synthetic fiber yarn, and can remove fine particles and flora and fauna plankton up to 5 μm in diameter.

The raw water having passed through the micro filter 4 is transferred to the upper open ozone dissolver 6. The ozone dissolver 6 is configured to supply ozone generated by the ozone generator 5, and raw water is purified by contact oxidation with ozone. At this time, the ozone dissolver 6 contacts and oxidizes ozone dissolved in water by diffusion of ozone by mixing in a pressurized state.

The raw water having passed through the ozone dissolver 6 is introduced into a biologically activated carbon 7 by the filtrate feed pump 6 ′. In the biological activated carbon (7), the growth of aerobic bacteria is promoted, and these aerobic bacteria reduce the amount of soluble organic carbon (DOC) and ammonia.

Raw water having passed through the biologically activated carbon tank 7 is collected in the purified water tank 8 in a purified state.

By the way, according to the conventional water treatment system configured as described above, the raw water discharged from the micro-filter 4 is introduced into the ozone dissolver 6 and finally purified in the biological activated carbon tank 7, the ozone dissolver ( In 6), the ozone dissolution rate was not great and the diffusion of dissolved ozone did not proceed smoothly, thus reducing the ozone oxidation efficiency of raw water, thus impairing the water purification efficiency.
