Description

Technical Field

[0001] The utility model relates to the technical field of ecological environmental protection, in particular to a sludge resource utilization and processing device. Background Art

[0002] Due to the influence of industrial wastewater, domestic wastewater, and aquaculture wastewater, a large amount of pollutants accumulate in water bodies, eventually forming sludge that settles at the bottom of the water. Simultaneously, the contaminated sludge affects the water, causing a series of coupled, complex pollution. With the rapid development of China's economy and population, the use of pesticides, fertilizers, phosphorus-containing detergents, and aquaculture antibiotics has continued to increase. This has led to a continuous increase in the levels of nitrogen, phosphorus, and residual antibiotics in water, disrupting the original ecological balance in the water body and causing eutrophication and the presence of antibiotics. This phenomenon is particularly prevalent in slow-flowing water bodies such as lakes, reservoirs, and bays.

[0003] The main characteristics of sludge are: (1) large sludge production, large-scale sewage treatment plants, and concentrated sludge production; (2) low organic matter content and high sediment content; (3) large differences in mud quality in different regions. The sludge moisture content of municipal sewage treatment plants is between 92% and 99.5%. It is necessary to reduce the sludge moisture content to a certain level before aerobic fermentation treatment is carried out to ultimately achieve resource utilization, volume reduction, and harmlessness of the sludge. In the traditional aerobic fermentation process, the sludge moisture content is first reduced to about 80%, and then straw, sawdust and other moisture regulating materials are added to adjust the moisture content to about 60%. In this process, a large amount of moisture regulating materials need to be added, which is costly and also leads to a significant increase in the volume and weight of the sludge, increasing the unit sludge processing fee. Therefore, this application discloses a sludge resource utilization and processing device. Utility Model Content
