优势菌生物增强SBR法处理校园生活废水中试优化操作

讨论了优势菌生物增强SBR法在校园生活废水处理中试过程中相关参数的优化问题。得出:在实验条件下出水浊度与COD之间的关系为一条直线;将处理终点定为浊度为17 20时,色度、气味和COD值,均达到生活杂用水标准且能满足冲厕和绿化的要求,经济效益较高;当进水量为13.5m3时24h处理水量最多;温度对低浊度盥洗室废水处理影响不大;但对于高浊度生活废水的处理,冬季的处理时间要比夏季长25%的结论。

THE TREATMENT OF CAMPUS SEWAGE WATER BY SUPERIOR BACTERIAL BIOAUGNENTATION SBR

This article is related to a new optimum process, of which, Superior Bacterial Bioaugmentation SBR was used to treat campus sewage wastewater. These conclusions have been drawn. Under the experimental conditions the relationship of the turbidity and COD is a straight line. When the end point of the treatment is turbidity being 17-20,color, odor and COD have reached the standard of CJ 48-1999 of China, the treated water can meet the requirement of the toilet washing and the grass watering, economic benefit is higher. When the quantity of the filling in water is 13.5 m~3, the quantity of the treated water is the most in 24 h. The effect of the temperature is small to the low turbidity washing room sewage, but to the high turbidity living sewage the time of exposure to air is 25% longer in winter than in summer.
