Immobilized microorganism particles, preparation method thereof and water quality purification method

The invention relates to immobilized microorganism particles, a preparation method thereof and a water quality purification method. The preparation method of the immobilized microorganism particles comprises the following steps: weighing a solid gel composition, heating the solid gel composition to be dissolved to form carrier solution, then cooling the carrier solution to 25-45 DEG C, and injecting microorganism suspension into the carrier solution to be evenly mixed, thereby obtaining microorganism dissolving solution; injecting the microorganism dissolving solution into calcium chloride solution, and carrying out rinsing with water after 1-2 hours, thereby obtaining a microorganism-immobilized gel; and adding the microorganism-immobilized gel into the calcium chloride solution, carryingout standing, removing the calcium chloride solution, rising the microorganism-immobilized gel with water, and carrying out filtering, thereby obtaining the immobilized microorganism particles. The gel is high in water conte
