The invention relates to a method using sea water or brine to produce ammonium magnesium phosphate. The method includes the steps of firstly, adding an inducer into the sea water or brine, and evenlymixing; secondly, adding a diluent into the seawater or brine, and regulate pH to allow the pH to stably be 7-9; thirdly, performing standing settling for 1-12 hours, wherein the reaction system is divided into supernate and solid sediments after the standing settling; fourthly, performing solid-liquid separation to obtain the solid sediments, namely ammonium magnesium phosphate. Compared with theprior art, the method has the advantages that ammonium magnesium phosphate low in solubility product is produced to recycle magnesium ions, and high magnesium recycling rate is achieved; due to the fact that the ammonium magnesium phosphate is more expensive than magnesium hydroxide, the method is good in economic benefits; when the magnesium ions in the sea water or brine is recycled, other divalent (or above) ions are partially and completely precipitated, the material basis for forming water scale is basically eliminated in the supernate obtained after the sediments are separated, and convenience is brought to subsequent treatment.

The invention relates to a method for synthesizing multi-element sustained-release compound fertilizer by using magnesium in seawater or bittern water. The multi-element sustained-release compound fertilizer is synthesized by adopting magnesium in seawater or bittern water as a raw material and adding elements such as phosphorus, potassium and the like. The method comprises the steps: inducting reaction, diluting and adjusting the pH, standing precipitating, carrying out the solid-liquid separation, cleaning with clean water and drying. The magnesium ion is recovered by generating the multi-element sustained-release compound fertilizer with lower solubility product, and the recovery rate of the magnesium is higher; and since the magnesium raw material is from the seawater or bittern water,the raw material cost is low, and the economic benefit is good; when the magnesium ion in the seawater or bittern water is recovered, other divalent (including ions higher than divalent) ions can bepartially or completely precipitated, a substance base for forming water scales can be basically eliminated in supernatant formed after the precipitates are separated, so that convenience can be provided for the subsequent treatment; and the separated multi-element sustained-release compound fertilizer contains elements such as phosphorus, potassium, magnesium, calcium and the like, so that the problem that the potassium ion sustained-release effect is poor can be solved.
