Abstract

The present study was initiated to help the simple and less expensive regeneration of activated carbons after saturation in rural area. In order to determine a regeneration time and the number of regeneration cycles, an adsorption test was necessary. Thus, 3h and 4 cycles of carbon regeneration are obtained after evaluation of the performance, percentage and adsorption capacity after each cycle. Regeneration percentages of 71.29, 54.05, 40.40, 28.06 % and 72.6, 69.84, 64.33, 34.98 %for respective concentrations of 30± 1.2 mg/L and 55 ± 1.6 mg/L are observed. Also, the performances of activated carbon 8.5, 10, 12, 20 g/L and capacities 24.04, 19.93, 14.9 and 10.35mg/g 35.7, 34.12, 31.43 and 17.09 mg/g respectively for dry season and rainy season were necessary to fix the number of cycles. The artisanal furnace with its ease of installation and its maximum temperature of 500±2°C is suitable for the regeneration of saturated activated carbon. Keywords— Regeneration, saturated activated carbon, artisanal furnace.

手工炉中饱和硝酸离子活性炭的热再生

本研究旨在帮助农村活性炭在饱和后实现简单、廉价的再生。为了确定再生时间和再生循环次数，需要进行吸附试验。因此，通过对每个循环后的性能、百分比和吸附量的评价，得到3h和4个循环的碳再生。30±1.2 mg/L和55±1.6 mg/L的再生率分别为71.29、54.05、40.40、28.06%和72.6、69.84、64.33、34.98%。在旱季和雨季，活性炭的性能分别为8.5、10、12、20 g/L，容量分别为24.04、19.93、14.9和10.35mg/g，分别为35.7、34.12、31.43和17.09 mg/g。手工炉安装方便，最高温度500±2℃，适用于饱和活性炭的再生。关键词:再生，饱和活性炭，手工炉。
