摘要: 为开发高效、合理、可行的养殖废水处理方法,以山东省烟台市某养鸡废水为研究对象,采用超滤-氨吹脱-电渗析-MAP工艺对样品进行处理。结果表明,超滤之后水样中COD、磷酸盐和总磷都呈不同程度的下降趋势,分别下降了72%、37%和39%;氨吹脱工艺对废水中的氨氮具有良好的去除效果,去除效率>99%,最终浓度为60 mg/L;电渗析过程脱盐率达86%以上;最后采用磷酸铵镁(MAP)结晶法对养殖废水中的磷进行回收,磷的回收率达93.7%。

Abstract: In order to develop an efficient, reasonable and feasible method for the treatment of aquaculture wastewater, ultrafiltration-ammonia stripping-electrodialysis-MAP process was used to treat the wastewater from a chicken in Yantai, Shandong province. The results showed that the concentrations of COD, phosphate, and total phosphorus in the water samples decreased to different degrees after ultrafiltration, by 72%, 37% and 39%, respectively; Ammonia stripping process had a good effect on the removal of ammonia nitrogen in wastewater, the removal efficiency was >99%, and the final concentration was 60 mg/L. The desalting rate of electrodialysis was over 86%; Finally, magnesium ammonium phosphate (MAP) crystallization method was used to recover phosphorus from the aquaculture wastewater, and the recovery rate of phosphorus reached 93.7%.

Key words: ultrafiltration, ammonia stripping, electrodialysis, MAP, aquaculture wastewater
