Abstract:

Domestic sewage and that from fruit and vegetable processing which enter the city sewage treatment plant were purified in a system of four fish ponds (1 – facultative, 2 – aerated, 3 and 4 -oxygenated), and in water outflowing from ponds into the river. Most of the bacteria were reduced in 50-93% in pond 1. In the remaining ponds of the technological system any greater reduction was only noted for the total number of bacteria on nutrient agar at 37°C; for total coliforms; fecal coliforms and the number of fecal streptococci. Most of the bacteria were reduced when sewage was flown through all four ponds. In the water outflow from ponds during the entire study period, the average reduction of the numbers of bacteria on nutrient agar at 20 and 37°C, of the total coliforms, fecal coliforms and fecal streptococci, amounted to 93-99%.
