Urban sewage treatment is a high energy consumption industry, and the electricity consumption of urban sewage treatment in the United States accounts for more than 3% of the total electricity consumption of the whole society
.
However, it is estimated that the potential energy contained in urban sewage is 10 times the energy consumption of sewage treatment.
In addition, the recycling of resources in the sewage treatment process should also be taken seriously
.
Especially phosphorus, the global phosphorus resources are about to be exhausted, and China's reserves can only be effectively supplied for 20-50 years
For sustainable municipal wastewater treatment, which is positioned at energy and phosphorus recovery, in 2003, China cooperated with the Delft University of Technology (TU Delft) in the Netherlands to propose the conceptual process shown in Figure 1-17
.
In order to effectively intercept the excess COD of sewage (except the carbon source required for denitrification and phosphorus removal) and convert it into methane by anaerobic digestion, the A section of the German A/B method was used to concentrate suspended and dissolved COD in the early years
