污水处理中温度对黑藻生长的影响
Influence of Temperature on the Growth of Hydrilla verticillata in the Wastewater Treatment
摘要
Abstract
[ Objective ] The research aimed to study the influence of temperature on the growth of Hydrilla verticillata in the wastewater treatment process. [ Method] By using the single factor experiment, the growth situation of H. verticillata in the different temperatures (5, 15, 25and 35 ℃ ) was observed in the treatment process of domestic sewerage. [ Result] H. verticillata grew luxuriantly in 35 and 25 ℃. After the cultivation of 15 days, the plant length, branch number, root number and biomass of H. verticillata in 35 and 25 ℃ respectively increased 2.8 and 1. 2 cm, 7.0 and 5.9 branch, 6.2 and 3.7 piece, 21％ and 25％, which were all significantly higher than that in 5 ℃. In the cultivation condition of 15 ℃, H. verticillata grew slowly. The increment of plant length, branch number and root number were high than that in 5 ℃,but they had no significant difference. [ Conclusion ] During 5 - 35 ℃, the higher temperature could promote the growth of H. verticillata in wastewater treatment process.关键词
