专利汇可以提供Treatment of reducible inorg. sulfur containing waste water专利检索,专利查询,专利分析的服务。并且PURPOSE: To obtain waste water with low BOD and an iodine consuming amount by a method wherein a waste water containing reducible inorg. sulfur compound is treated by using a filler material holding an organism phase containing sulfur bacteria to oxidize said sulfur compound to sulfuric acid almost completely even if said waste water contains high concn. and load of said sulfur compound.
CONSTITUTION: In case of treating a waste water containing thiosulfuric acid, thiosulfurous acid, sulfurous acid, polythionic acid and salts thereof, a sulfur compound (Na
2 S or the like) or sulfur by an immersion filter bed method, a filler material holding an organism phase containing sulfur bacteria is used as a filter bed and, while pH within a treating tank is maintained at 1W6, carbon dioxide gas and/or (bi)carbonate salt are coexisted as a carbon source to treat by said microorganism. As a pH regulating agent, NaOH KOH or the like may be used, but, when NaHCO
3 , Na
2 CO
3 is used as a carbon source, they act as a pH regulating agent.
