通过配制Ca2+的质量浓度分别为50、120、230、540、730 mg/L的进水,考察不同Ca2+含量对陶瓷平板膜生物反应器(C-MBR)膜污染的影响.实验数据表明,Ca2+的质量浓度为230 mg/L时,TP的去除率比Ca2+的质量浓度为50 mg/L时高30％左右,TMP上升速率比其它Ca2+含量下低约为37％,膜通量下降趋势比其它Ca2+含量下高约为27％.同时,在Ca2+的质量浓度为230 mg/L时,由于Ca2+强化了生物絮凝作用,故污泥混合液中的SMP及EPS较其它Ca2+含量下低.“,”In order to investigate the impact of Ca2+ content on membrane fouling in ceramic flat sheet membrane bioreactors (C-MBR),mass concentration of Ca2+ while being 50,120,230,540 and 730 mg/L,respectively,were added in the reactor.The results showed that the removal performance of TP was improved about 30％ with increasing mass concentration of Ca2+ from 50 mg/L to 230 mg/L;Correspondingly,TMP was about 37％ lower than that with other adding of Ca2+,and flux was about 27％ higher than that with other mass concentration of Ca2+.Since the effect of bilflocculation could be enhanced by Ca2+ when mass concentrations of Ca2+ was 230 mg/L,the contents of SMP and EPS were lower than that with other contents of Ca2+.
