摘要
鸟粪石结晶法是一种能同时回收废水中磷源和氮源的处理方法。本文总结了鸟粪石晶体的生长机理、颗粒形成和生长的影响因素,并着重比较了能够形成鸟粪石的各种反应器的优缺点。此外,文章总结了采用鸟粪石结晶法处理实际废水的相关研究,并对其经济效益做了评估。最后对鸟粪石结晶技术未来的研究方向进行了展望,提出了国内鸟粪石结晶技术研究的必要性。
Struvite crystallization is a technology to recover both phosphorus and nitrogen from wastewater. In this paper, the growth mechanisms, the factors affecting the granule formation and growth of struvite crystallization are summarized. And the comparison of advantages and disadvantages for different reactors forming struvite are stressed. Moreover, this paper summarizes the researches about adopting struvite crystallization to treat wastewater and assesses its economic benefits. Finally, the future development of struvite crystallization is prospected and the necessities to study struvite crystallization in China are suggested.
