【摘要】：筛选浮岛植物、浮岛植物种植材料、挂膜材料,考察浮岛材料的抗冲击能力、微生物菌剂强化效果,构建生物强化人工浮岛。通过现场实验,比较强化浮岛和普通浮岛的COD、TN、TP处理效率。结果表明,COD、TN、TP去除率均表现为生物棉组浮石组营养土组。利用中空微孔纤维束膜负载高效微生物菌剂的强化技术COD、TP去除率分别提高了20%左右、10%左右。泡沫浮盘比塑料浮盘有更好的抗冲击能力,运行2月后,完好无损。现场实验表明,强化浮岛的TN、TP去除率比普通浮岛分别高30%左右、40%左右。2种浮岛的污染物去除率随温度的降低和降低,但强化浮岛的下降幅度小于传统浮岛。在温度较低的11月,强化浮岛的TN、TP处理效率比普通浮岛分别高30%左右、20%左右。由此可见,与普通浮岛相比,生物强化人工浮岛不仅具有较高的处理效率,还有较好的稳定性,有更好的应用前景。
[Abstract]:Screening phytoplankton, phytoplankton planting materials, hanging membrane materials, investigating the impact resistance of floating island materials, strengthening effect of microbial agents, constructing biological enhanced artificial floating islands. The results showed that the removal rate of COD ~ (2 +) ~ (2 +) was the nutrient soil group of pumice group. The removal rate of COD ~ (2 +) was enhanced by using hollow microporous fiber bundle membrane loaded with high efficiency microorganism agent. The foam floating disk has better impact resistance than the plastic floating disk. After two months of operation, the results of field experiments show that the removal rate of TNT on the enhanced floating island is about 30% higher than that of the ordinary floating island by about 40%, respectively, and the pollutant removal rate of the two kinds of floating islands decreases with the decrease of temperature. When the temperature is low in November, the TNTP-treatment efficiency of the enhanced floating island is about 30% or 20% higher than that of the ordinary floating island, which shows that compared with the ordinary floating island, the efficiency of TNT TP treatment is about 20% higher than that of the normal floating island. Biological augmentation artificial floating island not only has higher treatment efficiency, but also has better stability, and has a better application prospect.
