Study on the current situation of municipal sewage sludge disposal and disposal process

In the process of urbanization, each city should actively respond to the call of the country and regard sustainable development as the core of development. Based on this, cities should pay attention to urban environment and ecological benefits. In cities, urban sewage plants should pay more attention to sludge treatment and disposal. Through strict sludge treatment, the impact of heavy metals and pathogens in the sludge on the urban environment will be reduced. Based on the continuous updating of sludge treatment technology and processing equipment in China, urban sewage plants must strengthen the rational disposal of sludge. In order to improve the efficiency of sludge disposal and avoid pollution to the environment, it is particularly important to do a good job in sludge treatment status and technology research. Briefly analyse the source and nature of sludge in urban sewage treatment and the status of sludge treatment and disposal, and focus on the relevant sludge treatment technology to provide reference for better application of sludge treatment technology.
