Treatment of brewery wastewater with photosynthetic bacteria

Using photosynthetic bacteria to treat brewery wastewater,the influence of some factors,such as: cultivation condition of the photosynthetic bacteria,dosage of lysate and temperature on the water-purifying effect were discussed.The results showed that,it is very easy for photosynthetic bacteria to form the superiority growth under the condition of artificial light source,nutrient fluid pH 7-8.The optimal dosage of the bacteria for the multiplication was 20% to 30%.During the purification of brewery wastewater,the best dosage of lysate was 30 mL/L,the removal rate of COD was as high as 80%.
