Method for processing food waste, sludge and excrement into composite soil

Abstract

The invention discloses a method for comprehensively treating kitchen garbage, sludge and excrement into composite soil, and belongs to the field of resource utilization of garbage. The method includes: using food waste, sludge and feces as main raw materials, several main operation steps such as sorting and separation, dry dehydration, adding fermenting bacteria, adding debugging agent, fermenting, and high-temperature sterilization. Straw or sawdust is used as a debugging agent and used for fermenting bacteria to make strains. This method can recycle and harmlessly process food waste, sludge and feces, and the composite soil made is light and loose, has good water permeability and ventilation performance, and has the ability to retain water and fertilizer, and contains a small amount of vitamins, auxins, and trace elements. etc., can promote the growth and development of plants. The process is simple, and the comprehensive treatment of kitchen waste, sludge and feces is effectively utilized to achieve resourceful and harmless utilization of waste.

Description

Technical field [0001] The invention relates to the field of garbage treatment, in particular to a method for processing kitchen garbage, sludge and feces into composite soil. Background technique [0002] In the improvement of soil pH and desertification, the consumption of chemical fertilizers is huge, but due to a series of reactions such as soil erosion, soil alkalinization, soil salinization, and non-agricultural occupation of cultivated land after chemical fertilizers are applied to the soil, the fertilizers are fixed, decomposed, and volatilized. The utilization rate is low. This not only causes the waste of nutrient resources, but also causes a series of environmental problems such as soil pollution, soil deterioration, soil compaction, and groundwater pollution. [0003] At present, fertilizers containing humic acid such as compound soil are gradually accepted and recognized by the agricultural material market, and are widely used in production. Facts have proved that th...
