Since the sustainable development strategy was put forward, environmental governance has become one of the most concerned issues in the core area of the public. With the continuous improvement of sewage treatment technology, the problem of water pollution is gradually transformed into the problem of mud pollution, in which the treatment and disposal of sludge are particularly complex, which has become another mountain of environmental protection. Sludge composition is intricate, physical and mechanical properties are special, sludge treatment and disposal is a typical environmental geotechnical problem, need to adopt a variety of technical means for mud treatment and disposal.

The contents of this book are from the mud treatment research achievements completed by the author and his team in recent years, including the National Natural Science Foundation of China (51478167), the Science and technology research project of Education Department of Jiangxi Province (GJJ180386), the Doctoral Research Start-up Fund project of East China Institute of Technology (DHBK2018048), more than 10 patents, and related papers, etc. The results of this book can innovate the theory of sludge treatment and disposal technology, solve the problems of sludge treatment in engineering practice, provide new methods for the improvement of sludge mechanics, and provide new power for sustainable development strategy in the application level.

This book by Yi Jinxiang responsible for the draft, which Hao Jiang、Jiacong Fang、Jingwu Zhang are responsible for Chapter 1, Chapter 6 preparations, Jinxiang Yi、Mingdong Li、Wenxia Yu are responsible for Chapter 2, Chapter 3 preparation, Xinming Li、Jiakang Hu、Mengtian Wang are responsible for Chapter 4, Chapter 5 preparations.

Due to the complexity of sludge composition and the difficulty of treatment, it is a multidisciplinary environmental geotechnical engineering subject, and many problems and research methods need to be further improved. Due to the limitations of the author's level, it is inevitable that there are some inside quotes in the book, and readers' criticism and correction are sincerely welcome.
