【摘要】：篩選浮島植物、浮島植物種植材料、掛膜材料,考察浮島材料的抗沖擊能力、微生物菌劑強(qiáng)化效果,構(gòu)建生物強(qiáng)化人工浮島。通過現(xiàn)場(chǎng)實(shí)驗(yàn),比較強(qiáng)化浮島和普通浮島的COD、TN、TP處理效率。結(jié)果表明,COD、TN、TP去除率均表現(xiàn)為生物棉組浮石組營(yíng)養(yǎng)土組。利用中空微孔纖維束膜負(fù)載高效微生物菌劑的強(qiáng)化技術(shù)COD、TP去除率分別提高了20%左右、10%左右。泡沫浮盤比塑料浮盤有更好的抗沖擊能力,運(yùn)行2月后,完好無損。現(xiàn)場(chǎng)實(shí)驗(yàn)表明,強(qiáng)化浮島的TN、TP去除率比普通浮島分別高30%左右、40%左右。2種浮島的污染物去除率隨溫度的降低和降低,但強(qiáng)化浮島的下降幅度小于傳統(tǒng)浮島。在溫度較低的11月,強(qiáng)化浮島的TN、TP處理效率比普通浮島分別高30%左右、20%左右。由此可見,與普通浮島相比,生物強(qiáng)化人工浮島不僅具有較高的處理效率,還有較好的穩(wěn)定性,有更好的應(yīng)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.
