  • 摘要: 针对分散型生活污水处理开发了气升回流一体化工艺，以校园生活污水为对象，研究其对生活污水中污染物的去除效果。该系统由好氧区、厌氧区、沉淀区和气升室组成，以曝气的剩余气体的气升作用实现混合液的回流，节省动力消耗。结果表明，本工艺对COD、氨氮及悬浮物（SS）有较好的去除效果，去除率分别达到80%、90%和75%左右，出水COD、NH4+-N及SS平均浓度在40 mg/L、6.5 mg/L和10 mg/L左右。当进水COD在100~1 000 mg/L之间波动时，出水水质稳定。该工艺有较强的抗冲击负荷能力，且可实现剩余污泥的自消解。本工艺具有结构紧凑、占地少，运行费用低，维护简单的特点。
    Abstract: According to the characteristics of decentralization wastewater, a novel airlift-reflux integrated process was developed. The campus wastewater is used for this experiment, its capacity to treat pollutants was observed. The system consists of four zones with aerobic zone, anaerobic zone, settling zone and airlift zone. In order to save power, the rest of aeration gas was gathered to realize the intermixture reflux. The treatment efficiency of campus sewage's pollutants was observed. The research results show that better removal of COD,ammonia nitrogen and SS could be achieved. The removal rates of COD, NH4+-N and SS can reach 80%, 90% and 75%, respectively. Correspondingly, the effluent average concentrations were 40 mg/L, 6.5 mg/L and 10 mg/L. When the influent concentrations of COD ranged from 100 to 1 000 mg/L, the effluent quality was stable. The updated process has a strong ability to resist shock loading and self-digestion of excess sludge. In addition, the characteristics of compact structure, land saving, low cost and easily maintenance can be obtained in this process.
