Coke oven sectors dispense phenol and cyanide into the circumferential ecosystem, which becomes a serious concern to the subsistence of the flora and fauna. The current study investigates phenol–cyanide treatment using carbon alginate beads immobilized with mixed bacterial consortium. Response surface using central composite design was contrived for the batch and packed bed bio‐column optimization study. The optimal removal conditions obtained in batch study were 89.77% and 82.33% for phenol and cyanide, respectively, with 10‐g/L adsorbent dosage, time 2 hr, and particle diameter 0.3 cm, whereas 87.22% and 90.97% with 22‐cm column height, column diameter 3 cm, 10‐ml/min flow rate, and 1‐hr operation time. The actual exposure time of the pollutants in the bio‐column reactor was calculated to be 22.15 min. Analysis of variance and model statistics predicted a high coefficient of determination for column operation with R² = .9950 (phenol), R² = .9976 (cyanide), and p values < .0001 stating significant model. The quantitative estimation of the combined external mass transfer and biodegradation effect was performed to evaluate correlation as (phenol) and (cyanide) with k_m = 0.052 and k_m = 0.055 cm/hr, respectively. The surface morphological study was executed by field emission scanning electron microscopy and Brunauer–Emmett–Teller surface area analysis depicting bacterial film development on the porous carbon matrix for effective treatment of binary system.

在固定生物柱反应器中使用固定的藻酸盐碳微珠评估传质效果和响应表面优化以减少苯酚和氰化物

焦炉部门将苯酚和氰化物分配到周围的生态系统中，这成为动植物生存的严重问题。目前的研究调查了使用固定有混合细菌聚生体的藻酸碳微珠对苯酚-氰化物的处理方法。设计了使用中央复合设计的响应面，用于分批和填充床生物柱优化研究。批处理研究中，苯酚和氰化物的最佳去除条件分别为109.7g和82.33％，吸附剂量为10g / L，时间为2小时，粒径为0.3 cm，而22cm为87.22％和90.97％。色谱柱高度，色谱柱直径3 cm，10 ml / min流速和1小时操作时间。计算出的生物柱反应器中污染物的实际暴露时间为22.15分钟。R ² = .9950（苯酚），R ² = .9976（氰化物），p值<.0001表示显着模型。进行了外部传质和生物降解作用的组合的定量估计，以k _m = 0.052和k _m = 0.055 cm / hr的相关性评估为（苯酚）和（氰化物）。表面形貌研究是通过场发射扫描电子显微镜和Brunauer-Emmett-Teller表面积分析进行的，该分析描述了在多孔碳基质上细菌膜的发育，从而可以有效地处理二元体系。
