Ammonia nitrogen removal equipment

Ammonia nitrogen removal equipment is a common problem caused by excessive ammonia nitrogen in water pollution. The ammonia nitrogen in water is mainly from urban domestic sewage, which is the decomposition product of nitrogen-containing organic matter and microorganism, industrial wastewater such as coking synthetic ammonia, and farmland drainage. When the content of ammonia nitrogen is high, it is toxic to fish and harmful to human body. Ammonia nitrogen contains a substance called NO-2, which can cause cancer. Of course, people will not drink it directly, but it is not ruled out that eating fish will lead to cancer.

The full-automatic ammonia nitrogen remover is an equipment for removing the excessive ammonia nitrogen in the polluted water. Using volcanic rock activated molecular sieve as filter material, fixed single bed process, downstream regeneration. When the equipment is working, the source water passes through the molecular sieve layer from top to bottom, and the ammonia nitrogen in the water is constantly removed by the molecular sieve adsorption. When the effluent reaches a certain amount, the molecular sieve in the primary tank will be saturated and lose the exchange capacity, so it is necessary to exit the operation for regeneration. At this time, the effluent is provided by other tanks to ensure continuous effluent. During regeneration, it is required to backwash the molecular sieve first to remove the suspended solids and other impurities that may intercept, and loosen the molecular sieve at the same time. Then, the medicine liquid is injected from the upper part of the tank, and the regenerated waste liquid is discharged through the blowdown valve. After the drug washing, the final positive washing process is 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 inhaled through the ejector, and automatically mixed to a predetermined concentration before being sent to the exchanger. The concentration of the regeneration agent can be freely adjusted through the valve.

Process characteristics of ammonia nitrogen removal equipment

1. Fully automatic control is adopted. After the commissioning by experienced water treatment engineer, no special person is required to take care of it, which greatly reduces the equipment operation failure caused by human factors.

 

2. At the same time, the treatment process of separate regeneration has greatly improved the utilization rate of equipment and molecular sieve. Reduce the cost of equipment investment.

 

3. GLC flow controller and GLA 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 fault caused by the valve is greatly reduced.
