The invention relates to an anaerobic treatment system for organic solid waste, which collects crop waste and animal feces, mixes them with microbial flora, fully stirs the three materials evenly with a mixing agitator, and ferments the mixture in an anaerobic preprocessor From 4 to 15 days, during the period, the permeate produced by the reaction in the preprocessor was collected and collected into the permeate container, and then flocculation sedimentation treatment, Fenton oxidation treatment and activated carbon adsorption treatment were carried out in sequence to effectively remove refractory organic pollutants. Finally, activated carbon is used for adsorption to meet the emission standards for recycling. The residual solid waste left in the preprocessor is subjected to secondary anaerobic composting. It becomes organic fertilizer in the process of anaerobic composting again. |
