| 2 | Blue-coke production technology and the current state-of-the-art in China显示文摘Blue-coke is a kind of char obtained by the low temperature pyrolysis of non-caking or weakly-caking coal with high volatile matter.It is generally granular with high reactivity,high electrical resistivity and high in fixed carbon but low in ash,sulfur,aluminum and phosphorus content.It has low price and extensive application decided by the raw coal and the production technology.This paper reviews pyrolysis reactor,process principle,technology characteristic and application state of blue-coke production technology in China.It includes vertical oven technology,rotary kiln technology and rotary-hearth furnace technology with external-heating,and vertical oven technology,rotary-disc furnace technology and conveyor-belt furnace technology with internal-heating.According to the existing problems in industrial blue-coke production technology,perspectives in terms of dust removal from volatiles,coke quenching and breakthrough of pyrolysis technology are given. | Yanchun Feng Shaoping Xu | 2020 | Carbon Resources Conversion2020，3，1： | 5 |
| 3 | FeCl3和AlCl3协同絮凝去除焦化废水中氟和有机物显示文摘氟是焦化废水中的待去除的主要污染物。采用FeCl3和AlCl3作为絮凝剂,研究了絮凝对焦化废水中氟和有机物的去除效果,并考查了不同剂量和pH条件下氟和有机物的去除率。结果表明:AlCl3和FeCl3对F-的最高去除率分别为94.4%和27.3%;在投量为20 mmol·L^-1时,FeCl3和AlCl3的TOC去除率分别达到27.6%和23.9%。因此,AlCl3对氟的去除率比FeCl3的更高,但FeCl3对有机物的去除率相对更高。加入Ca^2+可以促进氟的去除,但有机物的去除率会下降。另外,通过考察不同pH和铁铝配比对去除率的影响,探讨了同时加入FeCl3和AlCl3的去除效果。结果表明,最适合去除有机物和氟的工作条件是pH为6.5,AlCl3和FeCl3的比值为8∶2。本研究探索了FeCl3和AlCl3对焦化废水中氟和有机物的去除机理,实验结果可为焦化废水的深度处理提供参考。 | 刘梦洁 李硕 桑华俭 何立娟 徐磊 俞文正 | 2020 | 环境工程学报2020，14，8： | 4 |
| 4 | Removal of F- and organic matter from coking wastewater by coupling dosing FeCl3 and AlCl3显示文摘Coagulation and precipitation is a widely applied method to remove F-from wastewater.In this work,the effect of coagulation on the removal of F-and organic matter from coking wastewater was studied using Al Cl3and Fe Cl3as compound coagulants.The removal rates of F-and organic matter under different coagulant doses and p H conditions were investigated.The results show that the highest removal rates of F-by Al Cl3and Fe Cl3are 94.4%and 25.4%,respectively;when the dosage is 10 mmol/L,the TOC removal rates of Fe Cl3and Al Cl3reach 20.4%and 34.7%,respectively.Therefore,the removal rate of F-by Al Cl3is higher than that of Fe Cl3,but the removal rate of organic matter by Fe Cl3is relatively higher.The addition of Ca2+can promote the removal of F-,but the removal rate of organic matter decreases.In addition,by investigating the effects of different p H and Fe–Al ratio on the removal rate,the removal effect of adding Fe Cl3and Al Cl3at the same time was discussed.The results show that the most suitable working condition for the removal of organic matter and F-is that the p H is 6.5 and the molar ratio of Al/Fe is 8:2.Overall,the removal mechanism of F-and organic matter in coking wastewater by Fe Cl3and Al Cl3was explored in this study.The experimental results can provide reference for the advanced treatment of coking wastewater. | Shuo Li Mengjie Liu Fuming Meng Xia Hu Wenzheng Yu | 2021 | Journal of Environmental Sciences2021，33，12： | 2 |
| 5 | 响应曲面法优化粉煤灰活性炭-H2O2处理焦化废水显示文摘选择粉煤灰、活性炭、H2O2投加量、初始pH为自变量,以生化处理后焦化废水COD去除率为响应值,利用Box-Behnken实验设计与响应曲面法优化了粉煤灰-活性炭-H2O2处理焦化废水的工艺参数,建立了生化处理后焦化废水COD去除率的二次回归方程的预测模型,研究了每个自变量及其交互作用对焦化废水COD去除率的影响.结果表明:粉煤灰、活性炭、H2O2投加量、初始pH与COD去除率存在显著相关性,优化后的最佳工艺条件:粉煤灰85 g/L、活性炭29 g/L,H2O2投加量1.9 mL/L、初始pH=4.0,COD的去除率为72.54%.经实验验证,实际值与模型预测值拟合性良好,偏差仅为1.72%.活性炭经过7次重复吸附-超声脱附后,还能维持28%以上的脱附率,再生后可重复使用. | 陈俊平 黄征青 | 2020 | 河北师范大学学报(自然科学版)2020，44，6： | 0 |
