一种猪场废水厌氧消化液好氧处理方法
摘要：
本发明涉及废水处理技术领域，具体公开了一种猪场废水厌氧消化液好氧处理方法。本发明处理方法，包括两级AO工艺处理猪场废水厌氧消化液；在两级AO工艺的缺氧池内，添加未经厌氧消化处理的猪场原水，添加质量百分含量为20％～40％；本发明处理方法，添加原水至缺氧池后，提高微生物生长繁殖和反硝化所需的碳源，可有效改善猪场废水厌氧消化液的可生化性能；增强了缺氧池的反硝化作用，不仅加强了对氨氮的去除效果，而且给好氧池补充了碱度，并维持了好氧池pH值的稳定性；两级AO工艺处理系统运行过程中无需再补充碱度和碳源，大大节约了运行成本。
摘要（英）：

The invention relates to the technical field of waste water treatment and particularly discloses a pig breeding farm waste water anaerobic digestion solution aerobic treatment method. The treatment method comprises the steps that a two-stage AO process is used for treating a pig breeding farm waste water anaerobic digestion solution; pig breeding farm raw water untreated through anaerobic digestion is added into an anoxic pond of the two-stage AO process, and the addition mass is 20-40%. According to the treatment method, after the raw water is added into the anoxic pond, a carbon source needed by growth and reproduction of microorganisms and denitrification is increased, and biochemical performance of the pig breeding farm waste water anaerobic digestion solution can be effectively improved; the denitrification effect of the anoxic pond is enhanced, the ammonia nitrogen removing effect is enhanced, alkalinity is supplemented to an aerobic pond, and the stability of a pH value of the aerobic pond is maintained; in the operation process of the two-stage AO process treatment system, the alkalinity and the carbon source do not need to be supplemented, and the operation cost is saved greatly.
