What would be the reason for getting extremely high XRD peak intensity of precipitate sample compared to analytical grade Struvite?

In this study pure solution was used with Mg:PO4 molar ratio of 1.5:1 and 2:1 to reduce the phosphate concentration and the result obtained for PO4 reduction 94% and 98%.

Your question is not very clear. If your are talking about even increasing of intensity of all XRD peaks it just means that you have precipitated the phase with high crystallinity, which is good for the noise to signal ratio. If you are talking about strong increasing of only one or two peaks this is most likely the influence of texturing (preferred orientation), when crystals tend to grow in certain hkl direction. In this case just grind your sample thoroughly before XRD scan.
