Abstract
The nutrient ratio was varied in a series of bio‐reactors, treating a high‐strength, leachate, and having a sludge age of 20 days. The B0D5/N/P ratio varied from 100/3.2/0.1 to 100/5/1.1. The most effective, overall performance occurred at a B0D5/N/P ratio of 100/3.2/1.1. When the nutrient ratio varied from this level, there was an increase in effluent BOD,., suspended solids and metal concentration. At nutrient levels significantly below 100/3.2/1.1, the mixed‐liquor sludge bulked, with the volume of sludge generated doubling from 0.022 to 0.050 ml of settled sludge per mg of B0D5 removed (growth yield coeff. = 0.44).This publication has 1 reference indexed in Scilit:
