Sewage sludge shows excellent potential as pyrolysis feedstock in generating valuable products such as Activated Carbons (ACs). In this mini-review the preparation of sewage sludge- ACs by two kinds of pyrolysis conventional and microwave heating is presented and discussed. The main difference between conventional pyrolysis and the microwave-assisted method is the way the heat is generated, and both can provide ACs with different textural and chemical properties. Based on what was demonstrated in this work, it is possible to say that both kinds of pyrolysis (microwave and conventional methods) can produce high specific surface area and efficiently activated carbons from sewage sludge. It was also demonstrated that sludge-ACs produced by both pyrolysis methods could reach very high uptakes of pharmaceuticals from aqueous solutions. The van der Waals interactions, hydrogen bonding and π-π interactions of the aromatic ring of the adsorbent with the aromatic rings of the pharmaceuticals have been mentioned to be some of the main mechanisms governing the pharmaceuticals adsorption by ACs.

污水污泥作为热解原料在生产活性炭 (AC) 等有价值的产品方面显示出巨大的潜力。在这篇小型综述中，介绍和讨论了通过两种常规热解和微波加热制备污水污泥-活性炭。传统热解方法与微波辅助方法的主要区别在于产生热量的方式，两者都可以提供具有不同质地和化学性质的活性炭。根据这项工作的证明，可以说两种热解（微波和常规方法）都可以从污水污泥中产生高比表面积和高效活性炭。还表明，通过两种热解方法产生的污泥-活性炭可以从水溶液中吸收非常高的药物。
