A self denitrification water conditioning agents and its application

A self denitrification water conditioning agents, wherein the inorganic salt comprises promote bacterial growth of Thiobacillus denitrificans, Photosynthetic sulfur bacteria and nitrates and phosphates. Said Thiobacillus denitrificans and Photosynthetic sulfur bacteria ratio accounts for 80-95% and 5-20%, respectively, the total salinity of the inorganic salt is 1.5%. The composite microbial agents widely used, can be used to plug the aged oil sulfides, and microbial water treatment system of oilfield corrosion, flue gas desulfurization plants, but also for municipal sewage and wastewater sediment slaughter deodorization, removal of H2S , natural lake eutrophication control phosphorus and nitrogen removal in aquaculture degradation of nitrate and nitrite. The desulfurization agents have unique physiological characteristics and denitrogenation, desulfurization can be performed simultaneous denitrification, and the reaction product is safe and harmless, without adding organic matter, mild reaction conditions, the effect is significant, it can be used in many fields.
