NOVELTY - Collecting and treating for habitation village excrement and residues of kitchen and unit supplying method of cool, heat and power comprises (a) collecting habitation village excrement and house refuge; (b) methane tank and methane treating; (c) unit supplying system of power, cool and heat; and (d) treating methane solution and residues.    USE - The method is useful for collecting and treating for habitation village excrement and residues of kitchen and unit supplying method of cool, heat and power (claimed).    ADVANTAGE - The method not only in reduces investment of urban construction and environment pollution but also increases new energy and broadening the application of the new energy.    DETAILED DESCRIPTION - Collecting and treating for habitation village excrement and residues of kitchen and unit supplying method of cool, heat and power comprises (a) collecting habitation village excrement and house refuge: (i) separately discharging the excrement sewage and washes, sending excrement sewage into pre-treatment reservoir; (ii) discharging separately kitchen residues containing vegetable residual and clothes washed, sending organic rubbish into the pre-treating reservoir; (iii) separating the house refuge based on organic and inorganic, putting and collecting separately, sending organic rubbish into the pre-treating reservoir; and (iv) stirring uniformly the excrement sewage and organic rubbish in the pre-treating reservoir then sending to methane tank; (b) methane tank and methane treating: (i) sealing, separating from habitation village, warming, and deodorizing the methane, distributing the methane separately or concentrating in habitation village, anaerobic digesting excrement sewage, residues of kitchen and organic house refuge to produce methane in anaerobic fermenting tank, sending the methane into gasholder or airbag; and (ii) dry sulfur removing the methane before entering into mini gas turbine generator: coming out from the anaerobic gasholder to entering the water sealed tank for eliminating part of liquid water, entering dry sulfur removing tank to be adsorbed by ferric oxide and desulfurizer made from compound thereof to carry out chemical reaction, eliminating hydrothion, then eliminating water by dehydrator, sending the methane into after increasing pressure and fire retarding by fan mini gas turbine generator; (c) unit supplying system of power, cool and heat: sending the purified methane into mini gas turbine generator, driving mini gas turbine generator to drive the generator to generate power, working in parallel to supply power to village, driving the smoke lithium bromide cool/heat unit by the produced smoke to supply heat and cool locally the habitation village; and (d) treating methane solution and residues: it can be transmitted out of the village if it has outside usage; or else, discharging it directly into urban sewer.
