NOVELTY - An oxygen-enriched organism is treated by mixing solid-liquid waste, birds and beasts cultivation feces, and dry mixture at a mass ratio of 8:1:1- 7:1:2; fermenting channel-type oxygen-enriched organism at 50-70 degrees C for 4-8 days until moisture content reduces to less than 55%; and fermenting stacking-type organism for 4-8 days until moisture content reduces to less than 30%.    USE - Method for treating an oxygen-enriched organism for solid-liquid waste (claimed), particularly for treatment of sludge created by a sewage treatment plant in rural and urban areas, household waste, birds and beasts cultivation feces, solid-liquid waste in a plantation and a garden.    ADVANTAGE - The method quickens fermentation speed, reduces floor area and operation costs, and solves a problem of secondary pollution brought by solid-liquid waste in rural and urban areas.    DETAILED DESCRIPTION - Treatment of an oxygen-enriched organism involves mixing solid-liquid waste, birds and beasts cultivation feces, and dry mixture at mass ratio of 8:1:1-7:1:2; and adding and mixing 0.1-5 wt.% mineral mixture to form solid-liquid waste mixed materials. The solid-liquid waste mixed materials are transported into a fermentation tank (2) of a fermentation workshop. The mixed gas containing more than 40% oxygen is filled during fermentation of materials to raise temperature of materials and to perform fully aerobic fermentation at 50-70 degrees C for 4-8 days. Materials are fermented until moisture content reduces to less than 55%. Solid-liquid waste mixed materials are arranged into a long strip-like material stack after fermentation of channel-type oxygen-enriched organism. They are fermented for 4-8 days until moisture content reduces to less than 30%. Other nutrient additive is blended. Prilling and packaging are carried out to prepare into feature organic fertilizer according to different functions. An INDEPENDENT CLAIM is included for an oxygen-enriched organism treatment system    DESCRIPTION OF DRAWING(S) - The drawing is a sectional view of an oxygen-enriched organism treatment system.
