磷酸铵镁法去除和回收猪场污水中营养元素的研究进展

Study Status and Development of Struvite Crystallization from Swine Wastewater for Nutrient Elements Recovery

采用磷酸铵镁结晶法处理猪场污水,可实现猪场污水氮磷的去除及资源的回收,有利于畜牧业及磷资源的可持续发展。文章结合研究现状介绍了磷酸铵镁结晶法用于猪场污水的基本原理和影响因素,总结了目前研究的不足之处,同时展望了该法处理猪场污水的研究方向和发展前景。

More attentions have been paid to struvite formation from swine wastewater due to its simultaneously removal and recorery of nitrogen and phosphorous and realizing the resourcerization. The technique of struvite crystallization and its basic principle and influence factors for phosphorus removal from swine wastewater are reviewed in this paper. And the key points needing further study and the prospect are proposed.
