PROCEDURE FOR THE TREATMENT OF RESIDUAL PROCESS WATERS HIGHLY CONTAMINATED WITH AMMONIUM IN THE RESIDUAL WATER SECTOR.

摘要

Procedure for the treatment of process wastewater highly contaminated with ammonia in the wastewater sector, by treating the wastewater with nitrifying microorganisms (nitrifying) in the presence of a suspended support substance, adding to the wastewater, and suspending in them, a silicate support substance or finely divided support substance containing carbon, with a specific surface area of 20 m 2 / g, preferably 50 m 2 / g, and eventually subjecting nitrified wastewater to denitrification with denitrifying microorganisms (denitrifying), and the silicate support substance having an expansion volume of 5 to 80 ml / 2 g, and the non-carbon-containing grain substance, a surface pH value of approximately 6 to 9.
