Inhibition of nitrification in the packed bed reactors by selected organic compounds

Abstract

The effect of methanol, acetone, formalin and glucose on the nitrification process in the packed bed reactors has been investigated. For the utilized compounds the inhibition constant K, was determined according to Dixon's method. The determined values were as follows: methanol K, = 116.0 mgl-1: acetone K1 = 804.2 mgl-1; formalin K1 = 61.5 mgl-1. The value of K1 for glucose has not been determined because glucose in applied concentration up to 11.325 mgl-1 had no effect on the nitrification course.
