摘　　要：通过搭建投加负载氧纳米气泡的铝改性沸石并种植水生植物(植物+钝化剂组)、仅种植水生植物(纯植物组)、未种植水生植物也未加钝化剂(对照组)3套试验装置,考察了不同处理方式对黑臭水体的修复效果。结果表明,投加负载氧纳米气泡的铝改性沸石可抑制底泥中氮、磷的释放。70 d时,对照组和纯植物组中TP浓度与植物+钝化剂组的差异最大,比植物+钝化剂组分别提高260.14%和218.23%;40 d时,对照组和纯植物组中溶解性活性磷(SRP)浓度与植物+钝化剂组的差异最大,比植物+钝化剂组分别提高122.97%和74.32%。70 d后,植物+钝化剂组TP的平均浓度比对照组和纯植物组分别降低了71.23%和58.40%;40 d后,植物+钝化剂组SRP的平均浓度比对照组和纯植物组分别降低了54.40%和38.71%。70 d时,对照组和纯植物组中TN浓度与植物+钝化剂组的差异最大,比植物+钝化剂组分别提高了41.42%和65.29%;60 d时,对照组和纯植物组中NH_(4)^(+)-N浓度与植物+钝化剂组的差异最大,比植物+钝化剂组分别提高了96.17%和83.82%。投加负载氧纳米气泡的铝改性沸石可显著提高上覆水体的透明度、降低叶绿素a含量,并对上覆水中的氮、磷浓度略有降低作用。植物+钝化剂组水体的透明度比对照组提高了130.77%,比纯植物组提高了58.73%。植物+钝化剂组的叶绿素a浓度比对照组降低了55.56%,比纯植物组降低了50%。The effects of various treatment approaches on black and odorous water were explored by establishing three sets of experimental apparatuses:adding Al‑modified zeolite loaded with oxygen nanobubbles and cultivating aquatic plants(plant and passivator group),cultivating aquatic plants solely(pure plant group),and neither cultivating aquatic plants nor applying passivator(control group).The release of nitrogen and phosphorus in the sediment was effectively inhibited through the addition of Al‑modified zeolite loaded with oxygen nanobubbles.On Day 70,the TP in the control group and the pure plant group showed the most significant difference from the plant and passivator group,and increased by 260.14%and 218.23%,respectively,compared with the plant and passivator group.On Day 40,the concentration of dissolved active phosphorus(SRP)in the control group and the pure plant group exhibited the most significant difference from that in the plant and passivator group,being 122.97%and 74.32%higher respectively than that in the plant and passivator group.After Day 70,the average TP in the plant and passivator group decreased by 71.23%compared with the control group and by 58.40%compared with the pure plant group,respectively.After Day 40,the average concentration of SRP in the plant and passivator group was reduced by 54.40%compared with the control group and by 38.71%compared with the pure plant group,respectively.On Day 70,TN in the control group and the pure plant group showed the most significant difference from the plant and passivator group,and increased by 41.42%and 65.29%,respectively,compared with the plant and passivator group.On Day 60,the concentration of NH_(4)^(+)-N in the control group and the pure plant group exhibited the most significant difference from that in the plant and passivator group,being 96.17%and 83.82%higher respectively than that in the plant and passivator group.The addition of Al‑modified zeolite loaded with oxygen nanobubbles conspicuously enhanced the transparency of overlying water,dec
