应用PSB处理黄姜皂素废水的试验研究

A Study on Turmeric Saponin Wastewater Treatment with Photosynthetic Bacteria

皂素废水是一种酸度高、色度大、可生化性差的工业有机废水,利用光合细菌处理黄姜皂素生产废水并对影响因素进行试验研究的结果表明,在预处理后的废水中添加4.0‰酵母膏,pH7.5,接种量30%,光照条件2000Lx,温度30℃环境下处理6d,CODcr去除率最高。

Saponin wastewater is a kind of industrial orgamic wasterwater of high acidity, deep chromaticity and poor biodegradability. A preliminary study on turmeric saponin wastewater treatment with photosynthetic bacteria has been carried out, and the factors influencing the results have been analyzed. The experiments show that the highest CODcr elimination rate can be achieved in the optimal condition of adding 4.0‰ yeast extrat, adjusting pH value to 7.5, regulating the inoculation amont to 30%, putting it in the circurmstances of 2000 Lx and 30℃ for b days.
