摘　　要：厌氧酸化预处理养猪污水 ,以灭活病原微生物并使有机大分子降解成小分子 ,为菌藻系统资源化处理创造条件。同时 ,在室内条件下 ,比较了由小球藻、光合细菌、乳酸菌、红酵母及产朊假丝酵母所组成的菌藻生态系统在不同初始数量配比、不同环境条件下对经厌氧酸化预处理的猪场废水中 NH3 - N、有机质的去处效果及形转化藻蛋白的效率。结果表明 ,光照和黑暗条件对菌藻系统处理废水效果有一定差异 ,光照利于菌藻系统对氨态氮的去除 ,而黑暗条件则利于有机质的降解。振荡处理有机质去除效果比静置时高。同时 ,光照强度愈大 ,愈有利于氨态氮去除。组成的菌藻生态系统可使酸化猪场污水在 4 8h内 BOD5、NH3 - N的去除率分别达 96 .8%、98.7% ,同时产生 6 .5 4g/ L菌 -藻蛋白。显示出菌藻系统在资源化利用污染严重的养猪污水方面所具有的良好应用前景。The pathogenic bacteria were inactivated and complicated organic pollutants were degraded to simple substance by anaerobic acidization in advance for the piggery wastewater treatment. The effects of ecological factors on metabolic rate of organic carbon、NH 3-N and forming protein of bacteria-alga by the bacteria-algae ecological systems are studied under simulated conditions in this paper. The results showed that the metabolic functions of the bacteria-alga were affected by the initial ratio of the five sort microorganisms. When the ratio of the five germs was most suitably, the ability of the bacteria-algae system to remove ammonia and organic carbon were highest, and those of organic carbon、NH 3-N are removed in different rate in light and dark conditions. The light was more benefit to the bacteria-alga removing ammonia, but the dark condition was suitable to reduce organic carbon. Using batch experiment, the bacteria-algae system can remove more than 96.8% and 98.7% BOD 5、NH 3-N of the piggery wastewater. In the same time, we can get 6.54g/L bacteria-algae cell protein after wastewater treatment.
