细粒焦渣对废水中酚的吸附研究

Studies on the adsorption of toxic phenol with fine coke slag in coke plant

利用焦化厂细粒焦渣对苯酚的吸附 ,研究了各种因素 (焦粒大小、pH值和溶液的滤速等 )对吸附的影响 结果表明 ,在 2 5℃ ,滤速为 4 .5mL/min ,pH为 2～ 2 .5,浓度为 30mg/L的苯酚溶液中 ,酚的去除率可达 98% 探讨了细粒焦渣对焦化厂含酚废水处理的可行性 图 4 ,参

Based on adsorption of toxic phenol with fine coke slag in coke plant,the influences of various factors,such as particle size,pH and liquid flow rate on the soption capacity have been studied.The results show that the rate for the removal of phenol and is 98 % at a liquid flow rate of 5 mL/min using 30 mg phenol/L at 30℃ and pH 2.At same time, the feasibility for the treatment of phenolic wastewater with fine coke slag has been discussed in this paper.4figs.,10refs.
