摘　　要：以高盐、高磷榨菜废水为研究对象,探讨了厌氧序批式生物膜反应器(ASBBR)生物还原磷酸盐的除磷效能,考察了温度、pH、负荷及NO3--N浓度等因素对磷酸盐生物还原除磷的影响。研究表明:温度、pH、负荷及NO3--N浓度对磷酸盐还原除磷效果的影响显著。在水温为30℃、pH值为7.1、负荷为1.0 kgCOD/(m3.d)的条件下,反应器对COD和PO43--P的去除率分别为73.75%和39.85%;当NO--N为105～160 mg/L时有利于磷酸盐还原除磷。Taking the mustard tuber wastewater with high salinity and phosphorus concentration as research object, the phosphorus removal efficiency by biological phosphate reduction in an anaerobic sequencing batch biofilm reactor （ASBBR） was discussed. The influence of key factors such as temperature, pH value, organic loading rate and NO3^- - N concentration on phosphorus removal by biological phosphate reduction was investigated. The results show that these factors can significantly affect the phos- phorus removal efficiency by biological phosphate reduction. Under the conditions of temperature 30 ℃, pH 7.1 and organic loading rate 1.0 kgCOD/（ m^3 · d）, the removal rates of COD and PO3 ^- - P can reach 73.35% and 39.85% respectively. The NO3 ^-- N concentration of 105 to 160 mg/L is beneficial to phosphorus removal by biological phosphate reduction.
