상기와 같이 중수로 정수저장조(7)에 저장된 중수는 세척수로 재사용 된다.Heavy water stored in the purified water storage tank 7 as described above is reused as washing water.

이때 중수처리되는 과정에서 폐수의 온도는 순환되는 동안에만 저감되기 때문에 정수저장조(7)에 저장된 중수는 더운물로 재사용이 가능하게됨으로 저감되는 온도를 상승시키는 정도의 열량을 필요로 하기 때문에 가열에 따른 에너지의 사용을 절감할 수 있다.At this time, since the temperature of the wastewater in the process of heavy water treatment is reduced only during the circulation, the heavy water stored in the purified water storage tank 7 can be reused as hot water, and thus requires a heat amount to raise the reduced temperature. Energy use can be reduced.

상기와 같이 폐수를 정수처리하는 과정에서 각각의 제1,2,3,4,5,6의 필터(10)(11)(12)(13)(14)(15)의 필터체(9)에는 폐수에 잔존되어 여과된 각종 이물질(여과된 여과물)이 흡착 내지 부착되어 있어 이를 제거하고자 할 때에는 먼저 상기한 배수개폐밸브(26)를 폐쇄한 후 타측의 공급밸브(25)를 폐쇄하고 폐수개폐밸브(21)를 폐쇄한 후 필터수단(6)에 폐수를 공급하여 공급되는 폐수를 공급밸브(24)를 통해 제1,2,3,4,5,6필터(10)(11)(12)(13)(14)(15)를 경유하여 정수하고 정수된 중수액을 타측의 필터수단(6)의 제6,5,4,3,2,1필터(10)(11)(12)(13)(14)(15)로 역공급하여 타측 필터수단(6)의 제1,2,3,4,5,6필터(10)(11)(12)(13)(14)(15)의 필터체(9)에 여과되어 잔존하는 폐물질을 이탈시키고 배출밸브(19)를 개방하여 배출관(20)을 통해 외부로 배출하도록 하여 필터수단(6)을 세척하면 된다.Filter body 9 of the first, second, third, fourth, fifth, and sixth filters 10, 11, 12, 13, 14, and 15 of the waste water treatment process as described above. There is a variety of foreign matter (filtered filtrate) remaining in the waste water is filtered or adsorbed, if you want to remove it, first close the above-mentioned drain opening and closing valve 26, and then close the other side supply valve 25 and waste water The first, second, third, fourth, fifth, and sixth filters 10, 11 (supply) of the wastewater supplied by supplying wastewater to the filter means 6 after closing the open / close valve 21 are supplied through the supply valve 24. 12) (6), (5), (6), (6), (6), (6), (6), (6), (6), (6), (6), (6), (6), (6), (6), (6), (11) (12) 1, 2, 3, 4, 5, 6 filters (10) (11) (12) (13) (14) of the other filter means (6) The filter element 9 of 15 may be filtered to remove the remaining waste material, and the discharge valve 19 may be opened to be discharged to the outside through the discharge pipe 20 to wash the filter means 6.

이때 필터(10)(11)(12)(13)(14)(15)들의 세척은 일측의 필터수단(6)만이 세척이 됨으로 타측의 필터수단(6)의 필터(10)(11)(12)(13)(14)(15)들을 세척하고자 할 때에는 상기 개폐밸브들을 역으로 개폐하고 폐수를 공급하면 타측의 필터수단(6)의 필터(10)(11)(12)(13)(14)(15)들이 세척이 된다.At this time, the washing of the filters 10, 11, 12, 13, 14 and 15 is performed by washing only the filter means 6 on one side, so that the filters 10 and 11 of the other filter means 6 are washed. 12) (13) (14) (15) In order to clean the opening / closing valves in reverse and supplying the waste water, the filter (10) (11) (12) (13) of the other filter means (6) ( 14) (15) are cleaned.
