NOVELTY - Waste sewage ecological comprehensive processing system comprises a waste sewage treatment device for waste sewage treatment and pumping reaction slurry, a reaction device for providing a space for waste sewage reaction to form biogas and slag slurry, and a slurry treatment device for receiving slurry (biogas slurry and concentrated slurry) from the reaction device. The upper part of the slurry treatment device is provided with a biogas chamber. The biogas chamber is provided with a biogas pump for a biogas conveying and adjusting the biogas pressure within the slag slurry treatment device.    USE - The system is useful in harmless treatment of urban domestic waste, domestic sewage, rural cultivating waste, agricultural plant waste and forest growth waste.    ADVANTAGE - The system can process both liquid and solid waste sewage without conducting manure wet and dry separation pre-treatment; utilizes self-transport to achieve overall circulation and reaction conversion of materials; does not require separate mechanical stirring device; completely utilizes energy to convert waste sewage into fertilizer; achieves high waste utilization, reduces processing costs and increases production yield.    DETAILED DESCRIPTION - Waste sewage ecological comprehensive processing system comprises a waste sewage treatment device for waste sewage treatment capable of pumping reaction slurry, a reaction device for providing a space for waste sewage reaction to form biogas and slag slurry, and a slurry treatment device for receiving the slurry (biogas slurry and concentrated slurry) from the reaction device. The upper part of the slurry treatment device is provided with a biogas chamber. The biogas chamber is provided with a biogas pump for a biogas conveying and adjusting the biogas pressure within the slag slurry treatment device. A power device is used for feeding waste sewage treatment reaction slurry and the concentrated slurry of the slag slurry treatment device into the reaction device. The biogas slurry of the slag slurry treatment device is conveyed into the waste sewage treatment device for preparing reaction slurry mixed waste sewage or discharging to form a liquid fertilizer. The concentrated slurry of the slag slurry treatment device is conveyed into the reaction device to continuously react or discharge to form solid fertilizer after dehydration and dehumidification.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the waste sewage ecological comprehensive processing system in harmless treatment of urban domestic waste, domestic sewage, rural cultivating waste, agricultural plant waste and forest growth waste.
