Embodiment 1
[0016] A method for reducing nitrite in aquaculture water of the present invention comprises the following steps:
[0017] (1) Use 2g / m 3 Citric acid is used to treat the aquaculture water body, and the pH value of the aquaculture water body is adjusted to 7.5;
[0018] (2) After treatment in step (1), use 0.6g / m after an interval of 2 hours 3 Treatment of aquaculture water with potassium hydrogen persulfate;
[0019] (3) After treatment in step (2), use 0.5g / m after an interval of 3-5h 3 Sodium hypophosphite treats aquaculture water.
[0020] After the above steps, the denitrification efficiency reaches 95%.
Embodiment 2
[0022] A method for reducing nitrite in aquaculture water of the present invention comprises the following steps:
[0023] (1) Use 2g / m 3 Sulfamic acid is used to treat the aquaculture water body, and the pH value of the aquaculture water body is adjusted to 7.5;
[0024] (2) After treatment in step (1), use 0.6g / m after an interval of 2 hours 3 Potassium ferrate treatment of aquaculture water;
[0025] (3) After treatment in step (2), use 0.5g / m after an interval of 3-5h 3 Sodium hypophosphite treats aquaculture water.
[0026] After the above steps, the denitrification efficiency reaches 94%.
Embodiment 3
[0028] A method for reducing nitrite in aquaculture water of the present invention comprises the following steps:
[0029] (1) Use 1g / m 3 Citric acid is used to treat the aquaculture water body, and the pH value of the aquaculture water body is adjusted to 8;
[0030] (2) After treatment in step (1), use 0.5g / m after an interval of 2h 3 Potassium ferrate treatment of aquaculture water;
[0031] (3) After treatment in step (2), use 0.4g / m after an interval of 3-5h 3 Sodium hypophosphite treats aquaculture water.
[0032] After the above steps, the denitrification efficiency reaches 91%.
