摘要
贵阳市由于城市的发展,人口的增加,使南明河水体污染严重,环境受到破坏,河流的自我净化及自我恢复能力降低,对生态系统及人类的生存环境产生严重的影响。针对南明河的污染,提出采取生物修复技术、曝气复氧修复技术以及底泥疏浚控制修复技术进行治理,同时从污染源抓起,治其根本。通过采取生态系统自我修复能力和人工辅助相结合的技术手段,同时控制污染源,使南明河生态系统恢复到污染前的自然状态,恢复南明河生态系统合理的内部结构、高效的系统功能和协调的内在关系,实现人与自然和谐共处的生态环境。
With the population increasing and industrial development of Guiyang City, Nanming River has been seriously polluted. The self-purification of pollutant in river and self-restoration of river become weak, and the ecological system and survival environment are seriously damaged. In order to control the pollution in Nanming River, bioremediation, aeration technique, and sediment eco-dredging engineering are used. At the same time, controlling the pollution source is found to be a necessary way to control the river pollution. By developing the self-restoration capability of ecology, applying technical means, and controlling the pollution source, Nanming River＇s ecological system can be restored to its natural state. By restoring the internal structure, system function, and inner relationship of Nanming River＇s ecological system, the ecological environment of harmonious coexistence between man and nature can be available.
