摘　　要：将化学混凝方法与陶瓷膜分离技术相结合,开发了一体化陶瓷膜混凝反应器(CMCR),并对高浓度含磷废水进行了处理.结果表明CMCR对废水中的PO3-4-P和有机物有良好的去除效果.当膜面流速5m/s,操作压差0.08MPa,温度18～33℃,膜稳定通量达100L/m2·h,渗透液PO3-4-P含量小于0.4mg/L,COD值小于50mg/L,达到国家一级排放标准的要求.清洗后膜的通量恢复率达90%以上.A integrated reactor, based on ceramic membrane microfiltration and coagulation process （CMCR）, was developed to treat high-concentration phosphorus-containing wastewater. It was found that the reactor had good removal of phosphate and organic matters with CMCR; in the influent： PO4^3--P100-110mg/L, COD420 mg/L; in the effluents： PO4^3-P〈0.4mg/L, COD〈 50 mg/L, both met the Discharge Standard of China （GB8978-1996：COD ≤ 100mg/L;PO4^3-P≤0.5mg/L） and could be reused under very safe conditions. At a cross flow velocity of 5m/s and trans-membrane pressure of 0.08MPa, the steady flux was about 100 L/m^2·h. The flux was recovered to 90% of the initial value alter the cleaning of the membrane.
