微曝气生态浮床净化入湖河口污染河水原位模型实验
In-situ model experiment on purification of polluted river water into lake based on micro-aerated ecological floating bed
摘要
Abstract
Aiming at the problem of black-odor, oxygen deficiency and ammonia-nitrogen pollution of polluted rivers, a new type of ecological floating bed-micro-aerated ecological floating bed was developed, which combined biofilm packing, floating aquatic macrophyte and auxiliary aeration device. The purification efficiency of the polluted river water was studied by the model experiment in the outlet of Daqing River. The results showed when the hydraulic loading was 1500mm/d, the mean removal efficiencies of total nitrogen, ammonia nitrogen, total phosphorus and phosphate were 81.1%, 91.3%, 72.7% and 92.5%, respectively. Additionally, the floating bed showed better removal effect on organic matters. The cost of micro-aerated system to treat 1m~3 of polluted river water was only 0.007 Yuan. The micro-aerated ecological floating bed ran steadily, had a high efficiency of pollutants removal and low energy consumption. It was suitable for the environment of flowing water, which could be used in polluted river and estuary.关键词
