Abstract Wastewater generated from the coking processes has high load of organic as well as inorganic pollutants which requires the application of effective treatment techniques. In the present work, treatment of coking wastewater (CWW) through catalytic thermolysis has been carried out in batch mode with varying parameters such as type of catalyst, catalyst mass loading, pH, temperature and time. This process was followed by adsorption as second stage treatment process. The final parameters obtained are as Chemical Oxygen Demand (COD) 20 mg/L, cyanide 0.42 mg/L and nil amount of phenol from the high initial organic and inorganic load. The study aims reduction of COD, phenol, and cyanide content in the wastewater to the permissible limits. The mechanism and kinetics of thermolysis process have been also presented in this study.

常压催化热解吸附处理焦化废水

摘要 焦化过程产生的废水含有大量的有机和无机污染物，需要应用有效的处理技术。在目前的工作中，通过催化热解处理焦化废水（CWW）以间歇模式进行，具有不同的参数，如催化剂类型、催化剂质量负载、pH、温度和时间。该过程之后是吸附作为第二阶段处理过程。获得的最终参数是化学需氧量 (COD) 20 mg/L、氰化物 0.42 mg/L 和来自高初始有机和无机负载的苯酚量为零。该研究旨在将废水中的 COD、苯酚和氰化物含量降低到允许的限度。本研究还介绍了热解过程的机理和动力学。
