饮用水源周边水禽养殖污水净化人工湿地的设计

Design of constructed wetland for purification of sewage of waterfowl breeding around drinking water sources

水禽养殖是中国畜牧业的优势产业之一。随着水禽养殖规模的不断扩大,水禽养殖产业的污水排放对生态环境的破坏日益加剧,未经处理排放的污水使得周围地区的饮用水源受到污染。因此,研究人工湿地对水禽养殖污水净化处理技术和设计方法具有重要意义。本文通过对水禽养殖排放污水的成分分析,进行人工湿地的设计,设计内容主要包括湿地几何尺寸的确定、填料的选择设置、植物选择、防渗设计,以及系统运行五个部分。

Waterfowl breeding is one of the advantage industry of animal husbandry in China. Along with the continuous expansion of waterfowl breeding, sewage of waterfowl breed industry discharge to the destruction of the ecological environment is worsening, and discharge of untreated sewage that the area around drinking water sources is polluted. Therefore, it is important to study the techniques and methods of constructed wetlands for purification of sewage of waterfowl breeding. This article analyzed the element of composition through to waterfowl breeding, then according to the composition of constructed to design constructed wetland, design content mainly includes the determination of wetland geometry, the choice of packing set, constructed wetland plant selection, design of seepage control and system operation five parts.
