Description
본 발명은 정수로 오염된 과립 또는 분상의 활성탄을 재생하는 방법에 관한 것으로, 묽은 과산화수소(H2O2)수용액에 오염된 활성탄을 넣어 교반 가열하므로서 과산화수소가 활성탄의 미세공간에 침입케 하여 활성탄자체가 촉매제로 작용하여 H2O2를 H2O2→H2O+O↑로 분해시켜 발생되는 발생기 산소에 의하여 표백작용 및 살균작용으로 미세공간내에 부착한 이 물질을 분리시켜 액중에 배출케 한 후 맑은 물로 세척하여 건조하는 것이다.The present invention relates to a method for regenerating granular or powdered activated carbon contaminated with purified water, and the activated carbon contaminated in dilute hydrogen peroxide (H 2 O 2 ) solution and heated under stirring to allow hydrogen peroxide to penetrate into the microcavity of activated carbon. Acts as a catalyst and decomposes H 2 O 2 from H 2 O 2 → H 2 O + O ↑ by generator oxygen, which is generated by bleaching and sterilization, to separate this substance from the microcavity It is then washed with clear water and dried.
종래 활성탄의 재생은 가열로내에서 고온으로 가열하고 강력한 바람을 불어넣어 활성탄속의 미세한 구멍에 부착된 이 물질을 제거하는 방법 또는 높은 온도로 가열소성하여 활성탄의 미세구멍의 이 물질을 소각하는 방법 또 특허공고 번호 79-1078호에서 공개된 바와 같이 약 1000℃의 가열로에서 소성하면서 수증기를 취부하여 재생시키는 방법 또는 강한염산(HCl)속에 오염된 활성탄을 넣어 재생하는 방법등이 알려져 있으나 이들은 복잡한 특수가열로에서 고온으로 가열하고 수증기를 취부하거나 또는 송풍을 하여야 하므로 연료의 사용량이 많고 장치가 복잡하여 재생비용이 높은 결점이 있는 것이다.Conventional regeneration of activated carbon is a method of removing the substance attached to the fine pores in the activated carbon by heating to a high temperature in a furnace and blowing a strong wind, or burning the substance in the fine pores of the activated carbon by heating and firing at a high temperature. As disclosed in Korean Patent Publication No. 79-1078, a method of mounting and regenerating steam while firing in a heating furnace of about 1000 ° C. or a method of regenerating activated carbon contaminated in strong hydrochloric acid (HCl) is known. The heating furnace needs to be heated to a high temperature, and to install steam or blow air, which is a disadvantage in that the fuel consumption is high and the apparatus is complicated and the regeneration cost is high.
본 발명의 활성탄 재생방법은 이러한 종전의 재생방법의 문제점을 감안하여 과산화수소를 사용하여 간단한 방법으로 재생효과가 우수한 재생방법을 제공하는 것으로 공정에 따라 상세히 설명하면 다음과 같다.The activated carbon regeneration method of the present invention provides a regeneration method excellent in the regeneration effect by a simple method using hydrogen peroxide in view of the problems of the conventional regeneration method described in detail according to the process as follows.
오염된(사용한) 활성탄을 맑은 물로 세척하여 표면에 부착한 비교적 큰 이 물질들을 세척 제거한 후 묽은 과산화수소(0.8-3%) 용액에 넣어 교반하면 활성탄이 촉매체로서 작용하여 H2O2를 서서히 분해하여 발생기 산소를 생성하게 되고 가열하면 일층 맹렬히 반응하게 되며, 이 발생기산소는 활성탄의 미세공내에 부착된 이 물질들을 표백과 살균작용으로 분해 또는 분리시켜 액중에 배출케 한다.The contaminated (used) activated carbon is washed with clear water to remove and remove these relatively large substances attached to the surface, and stirred in diluted hydrogen peroxide (0.8-3%) solution. The activated carbon acts as a catalyst and slowly decomposes H 2 O 2 . The generator oxygen is generated and reacts violently when heated. The generator oxygen decomposes or separates these substances attached in the micropores of activated carbon by bleaching and sterilizing and discharges them into the liquid.
계속 가열하여 100℃정도가 되면 H2O2는 완전히 분해하여 물이 된다. 따라서 H2O2에 의한 독성은 없어진다.If it continues to heat up to about 100 ℃, H 2 O 2 is completely decomposed into water. Therefore, the toxicity by H 2 O 2 is eliminated.
이와 같이 처리한 후 물로 1-2회 세척한 후 다시 상기 과정을 2-3회 반복하여 세척건조한다.After the treatment as described above and then washed 1-2 times with water, the process is repeated again and again 2-3 times washing and drying.
H2O2의 용액농도는 활성탄의 오염정도에 따라 달리하며 5% 이상이 되면 초기에 너무 강력한 반응이 일어나 활성탄의 미세공속에 H2O2수용액이 침투하기 전에 산소가스에 의하여 방해되어 농도에 비례된 효력을 얻을 수 없다.The solution concentration of H 2 O 2 depends on the degree of contamination of activated carbon, and if it is more than 5%, the reaction is too strong at the beginning, and it is disturbed by oxygen gas before H 2 O 2 aqueous solution penetrates into the activated carbon microcavity. No proportional effect can be obtained.
이와 같이 하여 재생된 활성탄의 효과를 실험하기 위하여 물 10cc 중에 새활성탄과 재생활성탄을 각기 0.5g을 투입하여 기포발생을 시험한 결과는 기포의 발생상태가 양자 동일하였고, 또 상기조건과 같이 한 두 시험관에 묽은 H2SO41방울씩과 0.03% KMnO4수용액 4방울씩 넣고 가열한 결과 두개 모두 보라색으로 되어 재생활성탄은 불순물(유기물질)이 없음이 입증되고 새활성탄과 성능에 차이가 없음을 알 수 있었다.In order to test the effect of regenerated activated carbon, 0.5g of fresh activated carbon and regenerated activated carbon were put into 10cc of water, and the results of the test were as follows. Put 1 drop of diluted H 2 SO 4 and 4 drops of 0.03% KMnO 4 aqueous solution into the test tube, and both of them became purple.The activated carbon was proved to be free of impurities (organic substance) and there was no difference in performance from the new activated carbon. Could know.

오염된 습윤 분말 활성탄 5g을 물에 2회 세척한 후 3% 과산화수소용액과 같이 시험관에 넣고 알콜램프로 가열하여 반응시키며 계속온도를 높여 100℃가 되게 하여 3분간 계속 반응시켜 맑은 물로 세척하고 다시 상기조작을 1회반복하여 건조한다.5 g of contaminated wet powder activated carbon was washed twice with water, put into a test tube with 3% hydrogen peroxide solution, heated with an alcohol lamp and reacted. Continued to raise the temperature to 100 ° C. for 3 minutes, and washed with clear water. Repeat the operation once and dry.
이와 같이 얻은 재생활성탄을 H2SO4와 KMnO4에 의한 불순물 검사결과 보라색이 남아있어 불순물이 없음을 보였다. 또 분말 재생활성탄의 성능시험을 위한(메틸렌블루 탈색력)시험(KSM 1210)의 결과는 표 1과 같이 흡착력증가는 16.6%이었다.As a result of impurity test by H 2 SO 4 and KMnO 4 , the regenerated activated carbon thus obtained was free of purple impurities. In addition, the results of the (methylene blue decolorizing power) test (KSM 1210) for the performance test of the powdered activated carbon showed an increase in adsorption power of 16.6% as shown in Table 1.

[실시예 2]Example 2
오염된 습윤과립상 활성탄 2,000g을 증류수에 2회 세척하고 1% H2O2수용액 1ℓ와 같이 용기에 넣어 교반하면서 가열하여 반응시키며 계속 온도를 높여 98℃가 되고 20분간 가열하여 물로 세척하고 다시 2회 상기조작을 반복 처리한 후 건조시켰다.Wash 2,000 g of contaminated wet granular activated carbon twice in distilled water and place it in a container with 1 liter of 1% H 2 O 2 solution to heat and react with stirring. Continue to raise the temperature to 98 ℃ and heat for 20 minutes to wash with water. The procedure was repeated twice and dried.
이와 같이 얻은 재생활성탄의 H2SO4와 KMnO4에 의한 불순물 검사결과는 KMnO4의 보라색으로 되어 불순물이 없음을 알 수 있었다.The impurity test results of H 2 SO 4 and KMnO 4 of the regenerated activated carbon thus obtained became purple of KMnO 4 , indicating no impurities.
또 재생입상 활성탄의 성능실험을 위한 요오드 흡착력시험(JISK 1474)을 행한 결과는 표 2와 같이 흡착력증가는 19%이었다.In addition, the result of performing the iodine adsorption force test (JISK 1474) for the performance test of regenerated granular activated carbon was 19% as shown in Table 2.
