摘要
混合生物菌处理废水是近年来一项正日益得到广泛重视和应用的新型环保技术,本文运用微生物分解有机物技术,从混合生物制剂适宜的环境条件入手,研究总磷水样的浓度、投加量以及pH值、温度等条件对工业废水中总磷去除效果的影响。结果表明,在pH值为8.5～9.0左右,温度在25℃～30℃时混合生物制剂投加量为0.3 g对总磷浓度为40.0 ug/ml的模拟水样去除效果较好。
Abstract： As a new environmental protection technology, treatment of wastewater with mixed biological agents receives more attentions and applications in recent years. Starting from the suitable growth environment of mixed biological agents, this study a- dopts microbial organics decomposition technology to analyze the impacts of total phosphorus concentration, dosage, pH value and temperature on phosphorus removal. The best removal effect for water sample with total phosphorous concentration of 40 ug/ml was obtained when pH value is 8.5 ～9. 0, temperature 25℃ ～30℃ and mixed biological agent dosage 0. 3g.
