활성탄소섬유에 의한 색도제거에 관한 연구 : 위생매립장에서 화학적으로 처리한 침출수를 대상으로 = A Study on the Color Removal with Activated Carbon Fiber

다국어 초록 (Multilingual Abstract)

The activated carbon fiber(ACF) was used to remove color of leachate in sanitary landfill. Leachate treated with polymer coagulant was employed as the samples for the present with polymer coagulant was employed as the samples for the present study.
The average COD_Mn of the samples was 117.8 mg/ℓ and the color was 300 degree, which was measured by use of light transmittancy in the range of 400~650nm.
The physical properties of ACF were measured in terms of BET sufrace area and average pore-size, and its values were respectively 1465㎡/g, 14 A°. Experimental results of color removal test in the present study show that color substances adsorption by ACF if influenced by the BET surface area and pore size distribution of adsorbent.
When 100㎖ of the sample was passed through the adsorption column packed with 1.5g of ACF, removal rate of organics determined by COD was 84.1%, and color degree decreased from 300 to 56 providing a 81.3% color removal. The results shows that COD is correlative to the color degree. At pH 11, there was much more removal than at pH 3. The alkaline pH value for color removal is much significant because that of landfill leachate is in the range of 8~11. The results showed that adsorption treatment by ACF could be practically effective on the color removal to satisfy the 200 color degree of the legal standards.
But the processed and costs of adsorption treatment by use of ACF should be broadly discussed.
