, 2009 分析了磷石膏对苏打碱土团聚体稳定性、饱和导水率和盐分淋洗效果的影响。结果表明:水稳定大团聚体质量分数和饱和导水率均随磷石膏施用量的逐渐增加而不断提高,磷石膏施用量达到100%GR时,水稳性大团聚体质量分数从对照的0.03%增加到33.31%,饱和导水率从对照的0.13mm·d–1提高到3.14mm·d–1;出流液电导率和pH均随磷石膏施用量的增加而降低,磷石膏施用量达到100%GR时,出流液电导率和pH分别从对照的8.85mS·cm–1和10.26降低到3.46mS·cm–1和9.83。因此 ...

, 2010 通过添加聚合硫酸铁(PSFe)降低水体中的活性磷,对水体中磷浓度、藻类生物量、碱性磷酸酶活性(APA)、类胡萝卜素/叶绿素a(Car/Chl.a)等指标随时间变化的情况进行了研究.结果表明,添加PSFe后,活性磷(RSP)迅速下降,藻类生物量和Car/Chl.a在短期内并没有显著变化.总碱性磷酸酶活性(TAPA)则随着RSP的下降而迅速升高,溶解性碱性磷酸酶活性(DAPA)上升幅度较小.结果表明,PSFe是一种优良高效的除磷剂,水体中TAPA、DAPA对RSP变化敏感 ...

, 2011 以畜禽废水沼气发酵液为磷回收对象,采用曝气沉淀结晶法磷回收工艺,对回收产物进行水溶性磷连续浸提试验和玉米盆栽试验,考察畜禽废水磷回收产物的磷素动态释放情况、玉米盆栽的肥效以及磷素利用情况。浸提试验表明,磷回收产物经6次浸提,水溶性磷的释放量呈缓慢下降的趋势,第6次与第1次相比只下降了1.42%,总释放量占总磷的57.97%,证明磷回收产物（RPP）具有良好的缓释性,作为肥料使用时不易被水淋失。盆栽试验表明,用RPP以不同比例代替磷酸一铵作为肥料对玉米均能起到显著的增产作用,最佳的质量替代比例为40 ...
