NOVELTY - Comprehensive fuel gas, culture and water purification includes introducing carbohydrate wastewater (1) to material sterilization pool (2) and to water-pollutant separation process (3). Organic clean water flows into biological culture purification pool (5) and concentrated organic residue and liquid and other organic waste materials (4) are placed in fast putrefaction pool (8). Putrefaction gas is sent to material sterilization pool and dense organic material is introduced into anaerobic reaction chamber (7). Organic residue and liquid is introduced into residue-water separation process (11).    USE - The process is used for comprehensive fuel gas, culture and water purification. The method is useful for treatment of waste material and water.    ADVANTAGE - The process provides environment protection in urban and rural area or travelling place.    DETAILED DESCRIPTION - Comprehensive fuel gas, culture and water purification includes introducing carbohydrate wastewater (1) produced in manufacturing and daily life to material sterilization pool (2) and to water-pollutant separation process (3) for separating 80-90% of organic clean water flowing into biological culture purification pool (5) or for plant irrigation directly. The remaining 10-20% of concentrated organic residue and liquid and other organic waste materials (4) are placed into fast putrefaction pool (8). After 2-3 days, putrefaction gas such as hydrogen sulfide and carbon dioxide is sent to the material sterilization pool for strong oxidizing reaction. After putrefaction, the dense organic material is introduced into an anaerobic reaction chamber (7) in which methane fuel gas (9) is produced. The organic residue and liquid left after the reaction is introduced into residue-water separation process (11) in which separated organic residue fertilizer (10) can be used in some other way and separated liquid residue (12) can flow to the biological culture purification pool or can be used to irrigate plants directly.
