Water treatment system combining ozone injection and monitoring apparatuses

A water treatment system combining ozone gas injection apparatus and monitoring apparatus, comprising:

• a filtering apparatus used to filter and emit the water that needs to be treated;
• a sterilizing apparatus having an ultraviolet lamp, a transparent quartz pipe, an ozone transmission pipe, a non-transparent spiral water transmission pipe, and a sterilizing tube, wherein said ultraviolet lamp shines on the air contained in the quartz pipe, creating ozone gas and emitting it through said ozone transmission pipe, and wherein said non-transparent spiral water transmission pipe fully mixes the transmitted ozone gas containing water while the stored air flowing through the sterilizing tube is exposed to the ultraviolet lamp through said transparent quartz pipe, thereby killing bacteria and reducing the amount of ozone gas in the water flowing out to be drunk;
• an ozone gas injection apparatus having a main water pipe with a water inlet and a water outlet, a Venturi tube having an ozone injection point, and a check valve, wherein said ozone gas injection apparatus is used for absorbing ozone gas as the filtered water flows into said main pipe via said water inlet, and the water then passes through said Venturi tube to generate a relatively low pressure so as to absorb the ozone generated from said sterilizing apparatus and transmitted through an ozone transmission pipe, and wherein said check valve, which allows the ozone to flow through and then being absorbed into said main water pipe, can block the water from flowing out of said main water pipe into said ozone transmission pipe so that the ozone-absorbed water flowing out of said main water pipe via said water outlet, after being squeezed and impacted, is mixed with ozone thoroughly and flows into said sterilizing apparatus;
• and
• a monitoring apparatus including (i) a flow path having first and second path inlets respectively communicating with said water inlet upstream of said ozone injection point and said water outlet downstream of said ozone injection point;
• (ii) a flow meter adapted to measure flow rate and accumulated water flow to calculate the service life of filtering material of said filtering apparatus;
• and (iii) said flow meter including a pressure sensor positioned within said flow path and adapted to generate output signals to control the switch of said ultraviolet lamp.
