NOVELTY - Synchronize removal of organic, sulfide and nitrate in wastewater includes adding active sewage sludge to a reactor to make a biomembrane, and putting abio-substrate in entering water to bring up sulfate autotrophic denitrification bacteria. After sulfate autotrophic denitrification bacteria taking the predominance and the nitrate removing rate is up to 80%, 2-6C organic is added and nitrate quantity is increased to promote heterotrophic denitrification bacteria growth. Sulfate autotrophic denitrification bacteria and heterotrophic denitrification bacteria are balanced.    USE - For synchronize removal of organic, sulfide and nitrate in wastewater.    ADVANTAGE - The method has high treatment efficiency, no secondary pollution, low operation fee, and low rate of sewage sludge yield.    DETAILED DESCRIPTION - Synchronize removal of organic, sulfide and nitrate in wastewater includes adding active sewage sludge to a reactor to make a biomembrane, and putting abio-substrate in entering water to bring up sulfate autotrophic denitrification bacteria. Abio-substrate comprises sulfonium compounds, nitrate, bicarbonates and potassium acid phosphate. After sulfate autotrophic denitrification bacteria taking the predominance and the nitrate removing rate is up to 80%, 2-6C organic is added and nitrate quantity is increased to promote heterotrophic denitrification bacteria growth. Sulfate autotrophic denitrification bacteria and heterotrophic denitrification bacteria are balanced by competing and synergetic effect. Sulfide and nitrate removing rate is up to 98%. Under the two different synergetic effects of microorganism with two different nutrition types, sulfide and nitrate transform to elementary sulfur and nitrogen, while organic is degraded to carbon dioxide simultaneously. The entering water satisfies the concentration ratio of organic, sulfide and nitrate. The weight ratio of chemical oxygen demand (COD) and nitrogen is 3-8. The weight ratio of sulfur and nitrogen is not greater than 2.5. Containment load does not exceed 2 kgN/m3-d nitrogen. The operating condition includes reaction temperature of 20-35degrees C, pH of 7.5-10 and waterpower residence time of 8-24 hours. The element sulfur suspension grain is separated and recycled. The produced air is exhausted directly after washing. An INDEPENDENT CLAIM is included for an organic glass or stainless steel fixed bed biomembrane reactor used for synchronize removal of organic, sulfide and nitrate in wastewater.
