Abstract: As an extreme phenomenon of water pollution, malodorous black water body causes ecological damage, and seriously affects residents’ life and physical and mental health as well as the sound development of city. In this paper, the causes and pollution status of malodorous black water bodies in China were analyzed. The remediation technologies were classified into physical technology, chemical technology and biotechnology, and the principles, advantages, disadvantages and applicability of these remediation technologies were introduced. Through the analysis of practical projects in China and abroad, the experiences of success and failure were summed up. It is necessary to transform the traditional concept of remediation into a feasible remediation route. Only if we select proper combinations of technologies according to the actual situation and local conditions can we maintain a long-term remediation effect.

Key words: malodorous black water body, pollution status, remediation, physical technology, chemical technology, biotechnology, remediation direction
