The ammonia nitrogen removal equipment is for the removal of ammonia nitrogen in polluted water. Using volcanic rock activated molecular sieve as filter material, fixed single bed technology, countercurrent regeneration. When the equipment is working, the source water passes through the filter material sieve layer from top to bottom, and the ammonia nitrogen in the water is constantly removed by molecular sieve adsorption. When the effluent reaches a certain amount, the molecular sieve in the primary tank will be saturated and lose the exchange function. The regenerant must be added to stop the regeneration. At this time, the water is supplied by other tanks to ensure continuous water discharge. During regeneration, it is necessary to stop backwashing the molecular sieve to remove impurities such as suspended solids that can be trapped and loosen the molecular sieve at the same time. Then enter the liquid medicine from the upper part of the tank, and the regenerated waste liquid is discharged through the blowdown valve. After the drug washing, the positive and negative washing process shall be carried out to completely remove the residual liquid medicine in the molecular sieve layer. In the regeneration process, the traditional Chinese medicine liquid is automatically absorbed through the jet device, and automatically mixed to the predetermined concentration, and then sent to the exchanger. The concentration of the regenerant can be automatically adjusted through the valve.

 

 

 

Equipment features:

 

1. It adopts full-automatic control. After the field installation and commissioning, the equipment will operate again and again according to the initial set parameters. The ammonia nitrogen removal device does not need to be supervised by a special person, which greatly reduces the equipment operation failure caused by human factors. Good dream weaving, good dream weaving

 

2. Adopt the treatment process of simultaneous operation and separate regeneration, sewage treatment workflow. The utilization ratio of equipment and molecular sieve is greatly improved. Reduce the cost of equipment investment.

 

3. The special PLC flow controller and Ge multi valve controller are used to realize the modular control of the equipment. The control program of the control system is greatly simplified, and the setting and operation of the controller do not need professional engineers.

 

4. The control valve adopts imported pneumatic / hydraulic diaphragm valve, with stable and reliable performance and long service life. The circuit failure caused by the valve is greatly reduced.

 

The water quality after the above treatment can reach the standard of drinking water gb5749-85.

 

5. Through the combined process, the equipment can treat wastewater with different concentrations, with high removal rate of ammonia nitrogen, which can reach the national first level discharge standard ≤ 15 mg / L after treatment.

 

6. With low energy consumption and cost, the treatment cost per ton of wastewater is 5-10 yuan, which is far lower than the treatment cost of traditional process of 15-25 yuan / ton.

 

7. All the waste gas generated by the ammonia nitrogen removal system enters the ammonia absorption system, making the whole treatment more environmentally friendly.

 

8. The internal design is more reasonable, which solves the problem of low temperature influence on blow off efficiency and packing blocking after long-term operation.

 

9. The glass fiber reinforced plastic or carbon steel epoxy anticorrosive material is used to solve the problem of short service life caused by sewage corrosion of traditional equipment.
