光合细菌在有机废水处理中的应用

本文综述了国内外利用光合细菌处理有机废水的研究概况.高浓度有机废水已成为主要的水污染源.光合细菌处理法是一项新技术.复杂的有机物先经异养菌降解,生成低级脂肪酸等小分子物质,再由光合细菌降解.红螺菌科的一些菌在光照或黑暗、有氧或无氧条件下均能利用小分子有机物迅速增殖。废水BOD由10000mg/L以上降至1000mg/L以下,使水质得以净化,作为副产物的菌体蛋白可以综合利用.

Application of Photosynthetic Bacteria (PSB) to the Treatment of Organic Wastewater

This paper reports the research on PSB in treating organic wastewater. Some heterotrophic bacteria decompose complex organic compounds into low molecular substances such as lower fatty acid, and then PSB utilize them. Some strains of Rhosfirillaceae have been found to utilize lo-the conditions og light or dark, aeration or unaeration. wer. molecular compounds and to multiple rasidly under the Conditions of light or dark, aeration or unaeration. By means of the PSB, BODs in sewage massively decreases from more than 10000 mg/L to less than 1000 mg/L, In addition, the bacteria protein can be Used as by-product.
