摘要 利用超声溶胞作用考察不同浓度下污泥的分解效果。研究结果表明:随着超声波作用时间的延长,污泥中释放出的SCOD和VFA也在不断增加;并且随着污泥浓度的增加,超声污泥释放出的SCOD和VFA不但总量有明显增长,而且单位质量污泥破解释放的SCOD和VFA的量也在增加,在超声作用时间为5~45 min,污泥浓度为13 000 mg/L、17 000 ml/L、37 000 mg/L的情况下,污泥SCOD/VSS的范围为0.10~0.14 mg/mg;VFA/VSS范围为0.016~0.023 mg/mg;当比能耗相同时,随污泥浓度升高,单位质量污泥破解程度显著增加,因此,提高污泥浓度可以在低比能耗的情况下达到较高的能耗效应。
