Example Embodiment
[0040] Example 1
[0041] (1) Preparation of CaCl 2 Solution: Weigh 5gCaCl 2 , Dissolved in 495g distilled water to obtain 1% CaCl 2 Solution.
[0042] (2) Preparation of immobilized ammonia nitrogen degrading bacteria particles: 6g polyvinyl alcohol, 2g sodium alginate and 10g modified sodium clinoptilolite powder with a particle size of 200 mesh were added to 200ml distilled water, and heated at 70 rpm in a 70 ℃ water bath. Stir continuously at the rotating speed for 1 hour to prepare a mixed homogenate. After the prepared mixed homogenate is cooled to 35° C., 10 ml of high ammonia nitrogen degrading composite bacteria is added to it, and stirring is continued to prepare a mixed homogenate containing ammonia nitrogen degrading bacteria. Use a 50mL syringe with a needle to suck the mixed homogenate containing ammonia nitrogen degrading bacteria, and then drop it into 1% CaCl 2 In solution, needle and CaCl 2 The distance between the liquid surface of the solution is 15cm to ensure...

[0043] Example 2
[0044] (1) Preparation of CaCl 2 Solution: weigh 15gCaCl 2 , Dissolve with 485g distilled water to obtain 3% CaCl 2 Solution.
[0045] (2) Preparation of immobilized ammonia nitrogen degrading bacteria particles: add 20g polyvinyl alcohol, 0.2g sodium alginate and 3.3g modified sodium clinoptilolite powder with a particle size of 325 mesh in 200ml distilled water, and place it in a water bath at 80°C. Stir continuously at a speed of 80 rpm for 50 minutes to obtain a mixed homogenate. After the mixed homogenate is cooled to 30°C, 10 ml of high ammonia nitrogen degrading composite bacteria is added to it, and stirring is continued to prepare a mixed homogenate containing ammonia nitrogen degrading bacteria. Use a 50 mL syringe with a needle to suck up the mixed homogenate containing ammonia nitrogen degrading bacteria, and then drop it into CaCl with a mass fraction of 3% 2 In solution, needle and CaCl 2 The distance between the liquid surface of the solution is 2...

[0046] Example 3
[0047] (1) Preparation of CaCl 2 Solution: Weigh 50g CaCl 2 , Dissolve with 450g of distilled water to prepare CaCl with a mass fraction of 10% 2 Solution.
[0048] (2) Preparation of immobilized ammonia-nitrogen-degrading bacteria particles: 16g polyvinyl alcohol, 0.4g sodium alginate and 5.3g modified sodium clinoptilolite powder with a particle size of 200 mesh were added to 200ml distilled water, and placed in a water bath at 85°C. Stir continuously at 90 rpm for 45 minutes to prepare a mixed homogenate. After the mixed homogenate is cooled to 32°C, 10ml of high ammonia nitrogen degrading complex bacteria is added to the solution, and stirring is continued to prepare a mixed homogenate containing ammonia nitrogen degrading bacteria. Use a 50mL syringe with a needle to suck the mixed homogenate containing ammonia nitrogen degrading bacteria, and then drop it into 10% CaCl 2 In solution, needle and CaCl 2 The distance between the liquid surface of the solution...
