ABSTRACT

With the improvement of human life quality, sewage sludge (SS) production is increasing day by day, and its treatment is inevitable. As one of the by-products of sewage water treatment, SS contains a lot of pollutants. If the continuously produced sludge is not properly disposed and managed, it will cause great harm human existence. However, in many areas, the concept of SS treatment is only in the initial stage, and not recyclable, and may cause a series of environmental problems, thus threatening ecological security and human health. Therefore, in order to the harmonious coexistence of the earth and human beings, it is necessary to conduct reasonable treatment and management of SS. In the past, there have been many reports on the specific treatment methods of SS, but few reports on the comprehensive treatment and introduction of SS. Therefore, from the perspective of sludge recycling, combined with the concepts of SS reclamation, reduction and harmless treatment, this chapter introduces SS disposal and management methods in line with the sustainable development strategy and chemical pollutants and pathogenic bacteria in SS, so as to promote the promotion of new SS disposal and management methods. It also lays a foundation for the optimization of SS disposal and management strategy.
