光合菌处理豆制品废水影响因素的研究

Study of the Efective Factors on the Bean Productswaste water Treatment With Photosynthetic Bacteria

研究了在厌氧及微好氧条件下光合菌对豆制品废水的处理效果 .探讨了接种量、废水浓度、废水pH值、处理温度对CODcr去除率的影响 ,结果表明 :在pH值为 7 5、3 0℃、微好氧条件下 ,光合菌对废水的CODcr去除率最高 ,且接种量与CODcr去除率成正比 .

In this paper,the bean products waste water had been treated with Photosynthetic Bacteria(PSB) for 96 hours. The optimum conditions of the quantity of inoculation,pH,temperature and DO were determined in treating the waster water. The results indicated that: there was the highest removal rate for CODcr in the conditions of pH7 5,30℃ and DO (0 1 mg/L-0 5 mg/L). The removal rate for CODcr was proportional to the quantity of inoculation.
