摘要: 为解决低浓度污水处理工艺脱氮除磷过程中存在的微生物碳源不足的问题,本文研制了新型填料床-逐级曝气串联反应器.填料床分别采用珊瑚砂、竹炭颗粒、钢渣为填料,在好氧、厌氧兼顾的环境下,实现化学除磷、生物除氮.试验采用模拟生活污水,COD、TN、TP、氨氮的浓度为170—190 mg·L-1、27—30 mg·L-1、8—10 mg·L-1,23—25 mg·L-1.反应器在第27天启动成功,100 d稳定运行结果显示,当HRT为14 h,曝气池DO为3.5 mg·L-1,反应器处理效果良好,出水中COD、TN、TP、氨氮的浓度分别为30.7 mg·L-1、5.59 mg·L-1、1.0 mg·L-1、4.67 mg·L-1,达到《城镇污水处理厂污染物排放标准》(GB18918—2002)中的一级B排放标准.经钢渣填料床处理后的污水,TP浓度降到1 mg·L-1左右,在不排泥的情况下,实现TP的高效去除,同时有效避免了除磷与脱氮过程对碳源的竞争,实现了生物法对水体中富余氮、磷的高效去除.

Abstract: A new type of fixed-bed reactor contacted with aeration tank was developed to solve the insufficiency of carbon source in nitrogen and phosphorus removal process of general sewage water. Both in the aerobic and anaerobic environment, the chemical phosphorus and biological nitrogen could be removed in the packed bed (filler: coral sand, charcoal particles and steel slag). The contaminants in the simulated domestic wastewater had 170—190 mg·L-1 COD, 27—30 mg·L-1 TN,810 mg·L-1 TP and 23—25 mg·L-1 NH4+-N.The reactor started successfully in the twenty-seventh day. After running stablely for 100 days, the results showed that when the HRT and DO in the aerated water were 14 h and 3.5 mg·L-1 respectively, the reactor had good treatment effect. The concentration of COD, TN, TP and NH4+-N in the influent were 30.7 mg·L-1, 5.59 mg·L-1, 1.0 mg·L-1, and 4.67 mg·L-1 respectively, achieving primary class B effluent standard of GB18918—2002.The concentration of TP in the sewage after the treatment of slag packed bed dropped to 1 mg·L-1 approximately. TP in sludge could be effectively removed. Meanwhile, the competition for carbon source was avoided during the phosphorus and nitrogen removal process. The result was that surplus nitrogen and phosphorus was effectively removed from water.
