摘　　要：为研究农村黑臭水体的治理方法,用狐尾藻开展模拟试验,之后用“狐尾藻+人工曝气”法在某坑塘进行治理工程试验。结果表明,狐尾藻对水中总氮、氨氮、总磷具有明显的去除效果。在“控源截污+清淤疏浚”的基础上,通过“狐尾藻+人工曝气”组合工艺可明显消除黑臭现象,透明度和溶解氧明显提高。最终该坑塘黑臭水体氨氮、溶解氧、透明度均达到《农村黑臭水体治理工作指南(试行)》中表1监测指标阈值。因此,在“控源截污+清淤疏浚”的基础上,利用“狐尾藻生态净化+人工曝气”组合工艺对农村黑臭水体具有很好的治理效果。In order to study the treatment method of black and odorous water in rural areas,a simulation experiment was carried out in a pit with Myriophyllum spicatum+artificial aeration method.The results showed that Myriophyllum spicatum had obvious removal effect on total nitrogen,ammonia nitrogen and total phosphorus in water.On the basis of"dredging,source control and pollution interception",the combination method of"Myriophyllum spicatum+artificial aeration"could obviously eliminate the black odor phenomenon,and the transparency and dissolved oxygen were obviously improved.Finally,the ammonia nitrogen,dissolved oxygen and transparency of the black and odorous water body in the pit all met the monitoring indexes in Table 1 of the Working Guide for Rural Black and odorous Water Body(for Trial Implementation).On the basis of"dredging,source control and pollution interception",the combined method of"Myriophyllum spicatum ecological purification+artificial aeration"had a good control effect on black and odorous water body in rural areas.
