PIPE TYPE OZONE CONTACT EQUIPMENT FOR WATER TREATMENT

摘要

PURPOSE: Ozone contact equipment is provided which properly controls volume of ozone injection to raise ozone contact efficiency and gains economical advanced purification effect. CONSTITUTION: A pipe type ozone contact equipment comprises the parts of: an ozone contact unit which is connected to a grit chamber(1) to supply migration passage of original water and contacts ozone flown in from outside with original water to oxidize organic matters in ozone; an ozone oxidation rate measurement unit(3) which measures in real time ozone demand as the change of water quality which is passed through the ozone contact unit; an ozone control unit(OCU)(4) which injects ozone by instantaneous ozone demand(I.D) against original water measured from the measurement tool; a unit which accepts control signal from the OCU and generates ozone as much as I.D; and an ozone injection unit which is branched off at the set position of the ozone contact unit and injects ozone from the ozone generation unit into the ozone contact unit.
