摘要
[目的]研究3种湿地植物对养猪废水的脱氮除磷效果.[方法]采用人工湿地工艺处理技术,研究水葫芦、芦苇、水花生对养猪废水中氨氮(NH+4-N)、总磷(TP)、化学需氧量(CODCr)的去除效果.[结果]水力停留时间(HRT)为20 d时,人工湿地对CODCr、NH+4-N、TP的去除效果较好,平均去除率分别达到85.5%、90.6%和82.2%,达到了预期目的.[结论]该工艺能使工程化处理养猪废水达到国家标准.
Abstract
[Objective]To study the effects of 3 wetland plants on nitrogen and phosphorus removal in pig wastewater.[Method]Using artificial wetland treatment technology,removal efficiency of Eichhornia crassipes,Phragmites australias and Alternanthera philoxeroides on NH+4-N,TP,CODCr were studied.[Result]When the hydraulic retention time (HRT) was 20 d,the removal rate of CODCr,NH+4-N and TP was better by constructed wetland,the average removal rate reached 85.5%,90.6% and 82.2%,respectively,and achieved the desired goal.[Conclusion]This process can meet the national standards for engineering treatment of pig wastewater.
