摘要/Abstract

摘要： 采用芽孢杆菌和密刺苦草（Vallisneria denseserrulata）构造一种微生物和水生植物联用系统,探究其对水体氮、磷的去除效果及对密刺苦草生长的影响。结果表明,芽孢杆菌复合菌和密刺苦草联用组总氮去除率可达79.29%,优于密刺苦草、芽孢杆菌复合菌单独施用组;芽孢杆菌复合菌施用后对总磷的去除率为33.58%,低于单独种植密刺苦草组的75.62%和二者联用组的65.31%。总的来看,芽孢杆菌和密刺苦草联用对水体脱氮效果较好并有利于水生植物的生长,而单独使用芽孢杆菌对富营养化水体的除磷效果较差。

Abstract: A microbial and aquatic plant combined system was constructed using Bacillus and Vallisneria denseserrulata to investigate its effects on nitrogen and phosphorus removal in water and growth changes of plants. The results showed that the total nitrogen (TN) removal rate of the combined group of Bacillus compound bacteria and V. denseserrulata could reach 79.29%, which was higher than that of the individual application of V. denseserrulata and Bacillus compound bacteria. However, the removal efficiency of Bacillus compound bacteria on phosphorus was 33.58%, which was lower than that in the individual application group of V. denseserrulata (75.62%) and the combined group (65.31%). On the whole, the combined use of Bacillus and V. denseserrulata had a good effect on denitrification of water bodies and was beneficial to the growth of aquatic plants, but the individual application of Bacillus had a poor effect on phosphorus removal in eutrophic water bodies.
