NOVELTY - Comprehensive treatment of a domestic waste comprises sorting the domestic waste; breaking eliminated large interference; carrying out magnetic separation of glass, textile, metal, rubber, and plastic; primary sieving, and crushing; secondary sieving, and carrying out pneumatic separation; carrying out wind power separation and sludge waste treatment; pulping organic matter; completely decomposing the organic matter; centrifugal dewatering an anaerobic fermentation tank; sewage treating; and removing slag, mixing, and drying.    USE - Method for the comprehensive treatment of a domestic waste (claimed).    ADVANTAGE - The method is simple, and has high mechanization and automation degree.    DETAILED DESCRIPTION - Comprehensive treatment of a domestic waste comprises:    (A) feeding the domestic waste in a feeding port to continuously and uniformly convey to a sorting platform;    (B) eliminating large interference;    (C) breaking the eliminated large interference;    (D) carrying out magnetic separation of glass, textile, metal, rubber, and plastic;    (E) primary sieving;    (F) crushing material suitable for subsequent process of grain diameter;    (G) secondary sieving of organic matter and the residue soil separated dregs;    (H) carrying out pneumatic separation;    (I) carrying out wind power separation of plastic, paper, and organic matter;    (J) carrying out sludge waste treatment of excrement, sludge, and impurities such as plastic, fiber, and stone;    (K) pulping organic matter for anaerobic fermentation of organic matter slurry;    (L) conveying to an anaerobic fermentation tank; controlling temperature; stirring; completely decomposing organic matter to produce a marsh gas containing a combustible methane, and an impurity gas comprising carbon dioxide, water, and hydrogen sulfide; and purifying the marsh gas;    (M) centrifugal dewatering the anaerobic fermentation tank;    (N) sewage treating; and    (O) removing slag, mixing, and drying to obtain an organic fertilizer.
