APPARATUS FOR TREATING BALLAST WATER BY FILTRATION UV ELECTROLYSIS COMPLEX STERILIZING PROCESS

摘要

PURPOSE: An apparatus for treating ballast water by filtration UV electrolysis complex sterilizing process is provided to secure safety of ballast water and prevent pollution of inland and coastal waters by treating a large quantity of ballast water continuously and promptly and sterilizing harmful microorganisms and pathogenic bacteria completely. CONSTITUTION: The apparatus comprises a ballast water storage tank(1-1) in which ballast water is contained; a ballast water injection line(1-3) for transferring ballast water(1-2) contained in the storage tank to filtration unit(2-1); a rotational filter(2-2) horizontally arranged at the center inside the filtration unit; a filter cleaning brush(2-3) arranged at the outer side of the rotational filter; filter rotation unit(2-5) and filter rotation motor(2-6) for rotating the rotational filter; pressure gauge(2-4) and pressure relieving gauge(2-7) installed in the filtration unit to judge clogging degree of filter; cleaning water injection line(4-1), cleaning water pump(4-2) and cleaning water supply line(4-3) for cleaning the filter when the filter is clogged; suction pump(2-8) and UV-electrolysis complex sterilizing unit injection line(2-9) for supplying filtered treating water into the UV-electrolysis complex sterilizing unit; four UV lamps(3-4) horizontally arranged in UV-electrolysis complex sterilizing unit(3-1) in which UV sterilizing and electrolysis sterilizing are simultaneously performed; anode plates(3-2) and cathode plates(3-3) horizontally arranged; and electrolysis sterilizing control box(5-1) and UV sterilizing control box(5-3) for controlling power supply and operation of the foregoing units.
