Ammonia nitrogen blowing tower is a kind of equipment specially used to treat ammonia nitrogen-containing wastewater, and its main role is to remove ammonia nitrogen in wastewater through physical or chemical methods to meet environmental protection requirements. The following will introduce in detail the working principle, structural characteristics, use effect and precautions of the ammonia nitrogen blowing tower produced by our company.
First, the working principle.
The working principle of the ammonia nitrogen blowing tower is mainly based on the volatility and chemical reactivity of ammonia nitrogen. In an ammonia nitrogen blowing tower, wastewater is injected into the tower through a nozzle and is in full contact with air or oxygen. During the blowing process, ammonia nitrogen volatilizes at the gas-liquid interface and can also be converted into other harmless substances through chemical reactions. After blowing and dehydration, the ammonia nitrogen content of the wastewater is greatly reduced, reaching the environmental protection discharge standard.
Second, structural characteristics.
The structural characteristics of the ammonia nitrogen blowing tower mainly include the following aspects:
1.Tower design: The ammonia nitrogen blowing tower generally adopts a cylindrical tower body, and is equipped with a packing layer or a spray device inside to increase the contact area between wastewater and air and improve the blowing efficiency.
2.Water inlet system: Wastewater enters the tower through the inlet pipeline, and is evenly sprayed on the packing layer or spray device through the nozzle to ensure that the wastewater is in full contact with the air.
3.Air system: Air or oxygen is fed into the tower through the fan, which is in full contact with the wastewater to promote the volatilization and chemical reaction of ammonia nitrogen.
4.Drainage system: The wastewater after blow-off treatment is discharged through the drainage pipe, which can enter the follow-up treatment equipment or be discharged directly.
Third, the use of effects.
The use effect of ammonia nitrogen blowing tower is mainly reflected in the following aspects:
1.High ammonia nitrogen removal rate: Through physical and chemical actions, the ammonia nitrogen blowing tower can effectively remove ammonia nitrogen in wastewater, and the removal rate can reach more than 90%.
2.Good treatment effect: The ammonia nitrogen content of the wastewater treated by the ammonia nitrogen blowing tower is greatly reduced, the water quality is significantly improved, and the environmental protection discharge standard can be reached.
3.Easy to operate: The operation of the ammonia nitrogen blowing tower is relatively simple, and only the parameters such as water inlet, air volume and fan speed need to be adjusted to achieve stable operation.
4.Wide range of application: Ammonia nitrogen blowing tower is suitable for treating all kinds of ammonia nitrogen-containing wastewater, such as wastewater treatment in chemical, pharmaceutical, printing and dyeing industries.
4. Precautions.
When using ammonia nitrogen blowing towers, the following aspects need to be noted:
1.Influent water quality control: The influent water quality has an important impact on the treatment effect of the ammonia nitrogen blowing tower, and the influent water quality should be ensured to be stable to avoid the impact of too high or too low ammonia nitrogen concentration on the equipment.
2.Equipment maintenance: Regularly inspect and maintain the ammonia nitrogen blowing tower to ensure the normal operation of the equipment and prevent problems such as clogging and wear.
3.Safe operation: When operating the ammonia nitrogen blowing tower, the safety operation procedures should be observed to avoid accidents.
4.Waste residue treatment: The waste residue produced after the treatment of the ammonia nitrogen blowing tower needs to be properly treated to avoid secondary pollution to the environment.
To sum up, the ammonia nitrogen blowing tower is an efficient and practical wastewater treatment equipment, which can effectively remove ammonia nitrogen in wastewater, improve water quality, and meet environmental protection discharge standards. In the process of use, it is necessary to pay attention to influent water quality control, equipment maintenance, safe operation and waste residue treatment to ensure the stable operation of the equipment and the effect of wastewater treatment.
