specific Embodiment approach 1
[0004] Specific Embodiment 1: In this embodiment, the method for strengthening the removal of ammonia nitrogen in water by ozone catalytic oxidation is realized through the following steps: 1. Put a catalyst with a particle size of 1 nm to 10 cm in the reactor in the form of a fluidized bed or a fixed bed In the ozone catalytic oxidation contact reactor, the catalysts are arranged in 1 to 5 layers and the total thickness of the catalysts is controlled at 10 to 500 cm; 2. The wastewater containing ammonia nitrogen is flowed in a forward and reverse flow at a water flow rate of 1 to 50 m / h At this time, in the reactor, titanium plate microporous aerators, standpipe aerators, or the method of uniform air intake around the periphery are used to distribute ozone. The input amount of ozone depends on the water quality. Dosing in actual conditions, in theory, 4 moles of ozone is required for every mole of ammonia nitrogen oxidized, and the actual amount added is 1 to 10 times of the t...
specific Embodiment approach 2
[0005] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the catalyst in step 1 is zeolite or modified zeolite. Other steps are the same as in the first embodiment.
specific Embodiment approach 3
[0006] Specific embodiment three: the difference between this embodiment and specific embodiment one is that the catalyst is attached with titanium, iron, manganese, copper, cobalt, zinc, platinum, palladium, rhodium, ruthenium, molybdenum, silver, gold, The zeolite or modified zeolite of one or more components of vanadium, tungsten or nickel, when there are multiple components attached, the components are in any ratio. Other steps are the same as in the first embodiment.
