NOVELTY - A waste water comprehensive utilization system has a thickener thickening alcohol liquid, clear liquid and thick mash liquid. A full groove anaerobic reactor is placed at a downstream part of a concentrating machine. A water-distributing tank and a device are placed at a downstream part of the groove anaerobic reactor. An eddy internal circulation (EIC) anaerobic reactor is provided at a downstream part of the water-distributing tank. Marsh gas is sent to a desulfurization device and a bio-gas generator. A lithium bromide refrigerator is placed at a downstream part of the bio-gas generator.    USE - Waste water comprehensive utilization system.    ADVANTAGE - The system generates high amount of marsh gas, and has low operation cost.    DETAILED DESCRIPTION - A waste water comprehensive utilization system has a thickener utilized for thickening alcohol liquid, first clear liquid and thick mash liquid. A full groove anaerobic reactor is placed at a downstream part of a concentrating machine and operable to the thick mash liquid, second clear liquid and marsh gas of a water-distributing tank and a device. The water-distributing tank and the device are placed at a downstream part of the full groove anaerobic reactor, where the water-distributing tank is operable to the first clear liquid, the second clear liquid and vacuum waste water. An EIC anaerobic reactor is provided at a downstream part of the water-distributing tank to operate the water-distributing tank for mixing water for generating the marsh gas, where the generated granular sludge is utilized as strain or biological fertilizer. The marsh gas is sent to a desulfurization device and a bio-gas generator. The bio-gas generator is arranged on a downstream part of the desulfurization device to operate a firedamp cooker with a simple water heating device and release high temperature water and smoke. A lithium bromide refrigerator is placed at a downstream part of the bio-gas generator to operate the bio-gas generator to release of the high temperature water and flue gas for generating ice water.
