污水污泥肥料化利用的分析与研究

Analysis and Study of Utilization of Sewage and Sludge as Manure

随着世界工业的发展、城市人口的增加,工业废水和生活污水的排放量日益增多,导致污泥的数量迅速增加。为避免污泥产生的二次污染和利用污泥中的有效成分,污泥的处置已经成为全世界关心的问题。在分析了常见的污泥处置方式存在的各种弊端之后,提出污泥的肥料化利用发展方向,指出将稳定化、无害化处理后的污泥作为一种有机肥料使用,将成为我国一种很有应用前景的污泥处置方式。

With the global industrial expansion and the increase in urban population, the discharge of industrial effluent and domestic sewage is ever on the increase, resulting in the rapid increase in the quantity of sludge. With a view to preventing secondary pollution by the sludge and utilizing the active ingredients in the sludge, the disposal of the sludge has become a problem of interest in the whole world. After an analysis of the various malpractices in the disposal of the common sludge, the writers put forward the direction for the development of utilization of sludge as manure, point out that the use of sludge after stabilized and non-polluting treatment as an organic manure will become a sludge disposal method with prospects for use in China.
