污水处理过程中的侧流磷回收工艺研究进展
|
摘要
磷是一种不可再生的有限资源,过度排放会带来严重的水体富营养化。污水处理过程中存在泥相与水相的磷富集,在污水处理过程中进行磷回收是实现污水磷资源化的一种有效途径。以侧流离线的方式对主流生物处理过程中的富磷污水或污泥进行处理,通过沉淀或结晶等方式进行磷回收,已经取得广泛关注。探讨了国内外污水处理过程中侧流磷回收的相关工艺及其研究进展,旨在为污水处理过程中侧流磷回收技术的发展提供一定的思路与参考价值。
Phosphorus is a kind of limited nonrenewable resources,causing serious eutrophication of water bodies when it discharged overly. Concentrated phosphorus exist in sludge and water lines in the process of wastewater treatment,phosphorus recovered during the process is an effective way to realize phosphorus recycling of wastewater. Phosphate-enriched wastewater and sludge of the biological treatment process in mainstream was precipitated or crystalized for phosphorus recovery in sidestream flow,which has been widely studied. The related technologies and the research progress at home and abroad of phosphorus recycling in sidestream during the process of wastewater treatment was investigated,aims at providing certain theoretical foundation and reference value for the phosphorus recovery of sidestream flow in wastewater treatment process.
