Abstract

The invention discloses a system and method for cultivating nutrient soil through a domestic sludge anaerobic reaction, and belongs to the technical field of environmental disposal. The system is composed of a sludge anaerobic digestion device, a temperature monitoring and adjusting device, a PH monitoring and adjusting device and a finished product crushing and mixing device, and comprises a transversely arranged fermentation tank, a first stirring paddle arranged in the fermentation tank, a second stirring paddle arranged in the fermentation tank, a controller, a heat-conducting boiler, a first water tank, a second water tank, a first temperature sensor arranged on the first stirring paddle, multiple second temperature sensors arranged on the inner wall of the fermentation tank, a PH monitoring sensor, a PH adjusting tank containing an alkaline regulator, a pulverizer and a mixing chamber arranged on a truck scale. The effects of automatically adding fungicide and calcium oxide, conducting heating, fermenting and crushing and preparing organic nutrient soil can be achieved.

Description

technical field [0001] The invention relates to the technical field of environmental treatment, more specifically, it relates to a system and method for cultivating organic nutrient soil by anaerobic reaction of domestic sludge. Background technique [0002] The dewatered sludge of urban sewage plants is the solid waste generated from the treatment of wastewater in urban sewage plants. With the increase in the number of sewage plants under construction in my country, the sludge output will still increase. Municipal sludge contains a large amount of organic matter and nutrients needed by plants such as N, P and K. Using sludge as a vegetable substrate after fermentation treatment is an effective way to achieve the reduction, harmlessness and resource utilization of such solid waste. The open-air aerobic fermentation that is usually used has a lot of air pollution, and the advanced fermentation process requires a lot of equipment and power. Compared with the nutrient soil pro...
