In this study, a new material consisting of activated‐carbon‐containing magnetic oxide is prepared for assisted microwave (MW) irradiation treatment of coking wastewater. The optimum condition for degrading coking wastewater is 98.14% chemical oxygen demand (COD), under which 87.57% ammonia nitrogen (NH₃–N) can be removed. The results are verified by GC–MS, showing that most organic pollutants can be adsorbed by modified activated carbon (MAC). The surface morphology and elemental composition of MAC before and after microwave irradiation and adsorption is determined by scanning electron microscopy. After microwave irradiation, many apertures of pores looked relatively large. It can be shown that MAC as a catalyst in the microwave‐assisted treatment process has many advantages, including rapid degradation of COD and NH₃–N. In conclusion, microwave‐irradiation‐assisted MAC treatment of coking wastewater is a novel technology that is economical, efficient, and has broad prospects for development.

改性活性炭微波辐射降解焦化废水。

在这项研究中，准备了一种由含活性炭的磁性氧化物组成的新材料，用于焦化废水的微波辅助辐照处理。降解焦化废水的最佳条件是化学需氧量（COD）为98.14％，其中氨氮（NH _3为87.57％）。-N）可以删除。GC-MS验证了结果，表明大多数有机污染物均可被改性活性炭（MAC）吸附。通过扫描电子显微镜确定在微波辐射和吸附之前和之后的MAC的表面形态和元素组成。微波照射后，许多孔眼看起来相对较大。可以证明，在微波辅助处理过程中，MAC作为催化剂具有许多优势，包括COD和NH ₃ -N的快速降解。总之，微波辐射辅助MAC处理焦化废水是一种经济，高效，发展前景广阔的新技术。
