Background
Sludge is a solid precipitate produced during sewage treatment. The municipal sludge and the industrial sludge are mainly treated by landfill, but the method not only costs a large amount of capital and occupies a large amount of land resources, but also causes serious secondary pollution to the ecological environment.
In response to this, attempts have also been made to utilize sludge as a fertilizer for agriculture or greening; however, various heavy metals contained in the sludge can be enriched in the soil and enter a food chain through the absorption of crops, and the health of human bodies is finally harmed, so that the adaptability of the soil to the sludge utilization is limited; even if some sludge comes from urban domestic sewage and the heavy metal content is low, the odor emitted from the sludge seriously pollutes the environment, and pathogens, persistent organic pollutants and various agents added in the sewage treatment process pollute the ground surface and underground water systems and bring potential harm to the environment and human health. In addition, there is a method of reducing the amount of sludge by incineration, however, the method has a limitation in popularization and use due to problems such as high investment in sludge incineration facilities, large energy consumption, and high running cost.
The main reasons for the above phenomena are that domestic sludge treatment starts late, the basis of sludge utilization is weak, the utilization rate is low, many sewage treatment plants are directly stacked in outsides of the environmental sanitation department after being temporarily stored, and a proper sludge treatment method is not found; and secondary pollution is easily caused by random stacking of the sludge, so that the sludge resource is seriously wasted.
