Abstract

The invention discloses a device and a method for sewage collaborative reutilization comprehensive treatment. The device comprises a material heating device, a solid-liquid separating device, an oil-water separation device, a crushing device, a sand removing device, an adjusting device, a heat exchange device, a hydrolysis acidification device, an anaerobic fermentation device and a flocculating dewatering device. The device and the method for sewage system reutilization comprehensive treatment have the advantages of low treatment cost, high practical operability, short production cycle and the like, not only change kitchen garbage, landscaping garbage and city municipal sludge into treasure (biogas is used for power generation, biogas residues and biogas slurry are prepared into organic fertilizers, and grease is used for production of biodiesel), but also largely reduce landfill sites, and effectively prevent secondary pollution to the environment.

Description

technical field [0001] The invention relates to a comprehensive treatment device and method for synergistic resource utilization of sewage, which belongs to the treatment technology of kitchen waste, landscaping waste and urban municipal sludge. Background technique [0002] Food waste refers to food waste and food residues in families, schools, public canteens of institutions and catering industry, and is the main component of urban domestic waste. Food waste is a mixture of various wastes with a wide variety of components. Compared with other garbage, it has the characteristics of high water content, organic matter content, oil content and salt content, and rich nutrient elements. During the storage, collection, transfer and landfill process of food waste, due to its high moisture content and organic matter content, it is very easy to rot, smell and breed mosquitoes in a short period of time, which greatly pollutes the surrounding environment. The current treatment metho...
