采用包埋固定化细菌技术制成的包埋菌颗粒为载体的曝气流化床工艺,对城市给水厂氨氮等指标超标的2种原水进行试验.结果表明,针对2种微污染水源水,包埋硝化菌颗粒流化床都可以高效、快速地去除水体中的氨氮和亚硝酸盐氮.在水温为23～27℃,水力停留时间(HRT)30min时,1号水源水进水氨氮,亚硝酸盐氮质量浓度平均值为1.88、0.300mg·L~(-1),出水质量浓度平均值分别为0.31、0.106mg·L~(-1);2号水源水进水氨氮、亚硝酸盐氮质量浓度平均值为0.83、0.036 mg·L~(-1),出水质量浓度平均值分别为0.21、0.015 mg·L~(-1).包埋硝化菌流化床可以高效快速地去除不同类型微污染水源水中的氨氮,装置简单,操作、管理方便,是一项有广泛应用前景的微污染水处理技术.

The micro-polluted two raw water using entrapped nitrifying bacteria pellets (10% pellets stuffing ratio in volume) in airlift loop reactor with the system operated continuously under the condition of temperature 23 ～27℃ was studied.The result showed that it can remove NH_4~+-N and NO_2~-- N quickly and effectively under hydraulic retention time (HRT) 30 min When the influent concentrations of NH_4~+-N and NO_2~-- N is 1.88 mg·L~(-1) and 0.300 mg·L~(-1), the average concentrations is 0.31 mg · L~(-1) and 0.106 mg·L~(-1), respectively, for No.1 surface water. When the influent concentrations of NH_4~+-N and NO_2~-- N is 0.83 mg·L~(-1) and 0.036 mg·L~(-1), the average concentrations is 0.21 mg·L~(-1) and 0.015 mg·L~(-1), respectively, for No.2 surface water. This immobilized microorganism system is easy to be operated and will be wide used in the future.
