太阳能推流曝气技术在黑臭湖泊治理中的应用研究

Study on the Application of Solar Jet Aeration Technology in the Treatment of Black Odor Lakes

太阳能推流曝气技术是一种专门针对水库湖泊治理的技术,尤其在黑臭湖泊治理中效果最佳,该设备在工程中有投资小,效率高,优势明显。随着经济快速发展,诸多湖泊污染严重,多数湖泊水体缺氧,植物落叶等腐败,水体表现为厌氧状态,水体有异味,不适合水生生物生存,很多水生动植物消失,生态系统结构严重失衡,功能严重退化甚至丧失。在湖泊治理过程中,多数采用截污纳管、湖泊清淤、引水补水、曝气充氧、微生物生态化治理等技术;但是水库湖泊和河道的治理区别比较明显,多数湖泊离人口聚集区较远,治理成本和维护成本都较高,难度也较大。本文介绍一种太阳能推流曝气技术,能有效解决湖泊湾区水动力差,黑臭,缺氧等问题,是一种专门针对黑臭湖泊治理的关键技术。

Solar jet aeration technology is a kind of technology that is specially directed to the treatment of reservoir lakes,especially in the treatment of black odor lakes,which has the obvious advantages of small investment and high efficiency.With the rapid economic development,many lakes are seriously polluted.Most of the lakes are anaerobic,and plant leaves are rotten,and the water body shows an anaerobic state and has a peculiar smell,which is not suitable for aquatic life.Many aquatic animals and plants disappear,ecosystem structure is seriously imbalance,and the function is seriously degradation or even loss.In the process of lake treatment,most of the methods are sewage interception nanotubes,lake dredging,water diversion and replenishment,aeration and oxygenation,microbial ecological treatment technology.However,the treatment difference between reservoir lakes and river channels is obvious,and most lakes are far away from the populated areas,with higher cost of treatment and maintenance and greater difficulty.In this paper,a solar jet aeration technology is introduced,which can effectively solve the problems of poor hydrodynamic,black odor and hypoxia in the lake bay area.It is a key technology for black odor lake treatment.
