METHOD OF CONDITIONING AMMONIA SEWAGE FOR CIRCULATING WATER SUPPLY SYSTEMS

摘要

The invention relates to the treatment of water, can be used in the preparation of wastewater in circulating water supply systems and allows you to simplify the process and increase its efficiency while ensuring a similar degree of water stability. Ammoniacontaining wastewater with an organic matter content of not more than 30 mg O ₂ / l for BOD _{5 is} subjected to biochemical treatment in an aerotank for 2 to 3 hours in the presence of nitrifying and heterotrophic microorganisms fixed on fiberglass biocenosis with their ratio (100 - 1000): 1 the ratio of solid and liquid phases in the aero tank 1: (45 - 55). Simplification of the preparation process and improvement of its efficiency are achieved by eliminating the reagent agent, while ensuring a low corrosion rate and the absence of scale formation, as well as eliminating the possibility of water contamination by impurities. 4 tab.
