摘　　要：　济南南郊宾馆的排水量及杂用水量均较大,为此采用水解—上向流曝气生物滤池(UBAF)—纤维过滤器(加药除磷)工艺处理宾馆污水,通过将UBAF的滤层分成缺氧区和好氧区,使UBAF具有了碳化、硝化与反硝化的功能,其对氨氮的去除率>85%,对COD的去除率在80%左右,在回流比为50%的条件下对总氮的去除率约30%。UBAF出水投加硫酸铝后进行纤维过滤除磷,在投量为20mg/mgTP的条件下可确保出水TP<1mg/L。Hydrolysis / up-flow biological aerated filter (UBAF) / fiber filter (chemical phosphorus removal) process was used to treat the wastewater from hotel.UBAF was divided into anoxic and aerobic zone to exercise the functions of carbonation,and nitrification and denitrification.It had removal rate of ammonia nitrogen more than 85%,and COD removal rate about 80%.The removal rate of TN was about 30% in the case of return ratio of 50%.Phosphorus was removed by fiber filter after adding aluminum sulfate to the effluent from UBAF,and effluent TP<1 mg/L was achieved in the case of dosage of 20 mg/mgTP.
