【摘要】 进行了人工浮岛原位修复再生水景观河道的研究。人工浮岛的构建至关重要，直接影响着水体的修复效果。通过填料吸附性能研究，选择对氮、磷具有较强吸收能力的沸石、陶粒作为浮岛填料；以菖蒲、千屈菜和芦苇作为浮岛植物，对水质起到净化的同时又具有美化环境的作用。对人工浮岛原位修复再生水景观水体的效果进行了研究，结果表明，在温度为10~35℃、进水COD为16.00~88.56mg/L的条件下，系统出水COD、NH4+-N、TN、TP浓度分别为9.52~73.21、2.25~48.87、4.07~48.06、0.07~0.73mg/L，相应的去除率分别为5.6%~52.7%、2.1%~29.5%、2.2%~22.1%、8.9%~76.5%。其中，COD、 TP的出水浓度均达到了《城市污水再生利用景观环境用水水质》（GB/T18921-2002）中娱乐性景观环境用水排放标准。温度、植物和进水浓度是影响人工浮岛修复效果的主要影响因素。人工浮岛对COD、TN、NH4+-N的去除率随着温度的升高呈上升趋势，TP呈下降趋势，表明温度对COD、TN、NH4+-N的去除效果影响较大，对TP无明显影响；植物的不断生长增强了浮岛对COD、TN、NH4+-N的去除效果，而对TP的影响较小；COD、TN、NH4+-N、TP的去除率均随着进水浓度的增加而增加。研究了人工浮岛-植物带组合修复技术对再生水景观水体的修复效果。结果表明，在温度为10~35℃、进水COD为16.00~88.56mg/L的条件下，人工浮岛-植物带出水COD、NH4+-N、TN、TP浓度分别为6.62~70.57、1.50~45.70、3.16~43.46、0.07~0.73mg/L，相应的去除率分别为9.0%~70.1%、4.8%~52.9%、5.8%~41.7%、12.3%~87.4%。可见，植物带的构建进一步增强了人工浮岛的修复效果。更多还原

【Abstract】 In this thesis, using artificial floating islands to in-situ bioremediation treat reclaimed water. It’scritical to construct artificial floating island which irectly affects the water restoration effect. Studyon the adsorption properties of the filler, selection of nitrogen, phosphorus with zeolite, ceramicstrong absorptive capacity as floating filler. Calamus, lythrum salicaria and reed as a floating islandplant, the water to purify and has the function of beautifying environment..Repair effect of artificial floating island of reclaimed water landscape of river. The results showthat,under the conditions of temperature of10~35℃, the influent COD of16.00~88.56mg/L,theeffluent concentrations of COD, NH+4-N,TN,TP for the combined process were9.52to73.21mg/L,2.25to48.87mg/L,4.07to48.06mg/L,0.07to0.73mg/L, and the removal efficiencies were5.6%to52.7%,2.1%to29.5%,2.2%to22.1%,8.9%to76.5%.The effluent quality of COD, TP achievedthe entertainment landscape water discharge standards in the city sewage recycling landscape andenvironmental water quality (GB/T18921-2002).Temperature, plant and influent concentration is the main factor influencing the artificialfloating island restoration. Artificial floating island of COD, TN, NH+4-N removal rate with theincrease of temperature rise, the downward trend for TP, which indicates that the removalof COD, TN, NH4+-N temperature is larger, has no obvious effect on TP; Plant growth enhance theremoval efficiency of COD, TN, NH+4-N Island, and the effect of TP on smaller; COD, TN,NH4+-N, TP removal rate increases with increasing the inletconcentration.Through analysis the factors which affect the removal of pollutants on the artificial floatingisland. The results showed that, temperature and floating island plant are important factors affect theartificial floating island to remove water pollutants, has little effect on the water inlet concentration.Study on the artificial floating island plant with repair effect of reclaimed water landscape ofriver. The results show that, under the same conditions of artificial floating island, the effluentconcentrations of COD, NH+4-N, TN, TP for the combined process were6.62to70.57mg/L,1.50to45.70mg/L,3.16to43.46mg/L,0.07to0.73mg/L, and the removal efficiencies were9.0%to70.1%,4.8%to52.9%,5.8%to41.7%,12.3%to87.4%. Visible, build further enhances the repaireffect of artificial floating island withplants.更多还原
