Abstract

The invention relates to a method for treating liquid manure by virtue of a compound microorganism nest. The method comprises the following steps of: (1) carrying out pre-treatment on liquid manure in a standing still way in the presence of oxygen to obtain pre-treated liquid manure; (2) paving a bottom material layer at first, and then paving a packing layer on the upper surface of the bottom material layer, then paving and spreading a compound microbial agent on the upper surface of the packing layer, then mixing a mixture with a bacterium liquid, and then paving and spreading on the compound microbial agent, and standing still for fermentation to prepare the compound microorganism nest; and (3) charging the pre-treated liquid manure to the upper surface of the compound microorganism nest, fermenting, and crushing and granulating the fermented compound microorganism nest to prepare an organic fertilizer. According to the method disclosed by the invention, the compound microorganism nest is used as a main heat source for treating liquid manure for the first time, and main water in the liquid manure is discharged into air in a form of vapour, thus avoiding pollution to environment and solving the problem about drying of the liquid manure; and other energy substances do not need to be added.

Description

technical field [0001] The invention relates to a method for treating excrement by using a compound microbial nest, and belongs to the technical field of comprehensive utilization of livestock excrement. Background technique [0002] Untreated manure is a major source of pollution from livestock farming and urban life. Fecal water produces odor, which seriously affects the normal life and work of the surrounding people; fecal water has eutrophication, and the survival rate of water organisms in rivers and other surface waters decreases, polluting water bodies; fecal water seeps into groundwater, causing pollution and affecting drinking; direct discharge of fecal water When it reaches the farmland, it will continue to ferment and cause the roots of the plants to burn, and the pH value of the land will increase to form alkaline soil. [0003] Generally, the moisture content of untreated feces is 80-95%, and the quality index range of aquaculture manure is as follows (mg / L): B...
