Open publisher page 1 citations

Abstract

In this paper the results of experimental study on treatment of gelatin production wastewater with photosynthetic bacteria is reported. The influence of illumination, dissolved oxygen, pH and bacterium's number on the removing rate of COD is discussed. The results have proved that the illumination, dissolved oxygen is beneficial to the reaction and the pH value of 6～7 is suitable. The bacteria volume should be 1/3～1/5 of the wastewater one. By this method, the removing rate of COD can reach 95% and 98%.
