兼氧技术应用于有机污泥的处理

应用兼氧技术处理有机污泥，对处理过程中挥发性脂肪酸的生成、N元素的变化、兼氧微生物的种群进行了检测，结果表明，有机污泥经过24h兼氧反应后，污泥中的有机物得到降解，酸化反应生成了质量浓度的2531mg/L的乙酸；系统中NH3－N含量略有上升；兼氧反应过程中的微生物以异养型的产酸细菌为优势菌种。污泥被水解酸化后回流到废水处理系统，系统基本无剩余污泥排放。

Study on the Application of Facultative Technology in Organic Sludge Treatment

The production of volatile fatty acid, the change of element N and the strains of facultative aerobes have been examined during the treatment of organic sludge by facultative technology. The organics in sludge are degra ded after oxidation reaction of 24 h. The mass concentration of acetic acid produced in acidification reaction is over 2531 mg/L. The content of NH 3 N in the system is slightly increased. Heterotrophic bacteria producing acids is the dominant strain during facultative reaction. The treated sludge is returned to wastewater treatment system without residual sludge discharge.
