Product Overview
This equipment is specifically designed for the treatment of high ammonia nitrogen wastewater. High ammonia nitrogen wastewater widely originates from fertilizer production, coking, landfill leachate, aquaculture, chemical, pharmaceutical, and electronics industries. Traditional treatment processes such as stripping, steam stripping, and biological nitrification/denitrification suffer from high energy consumption, large footprint, requirement for external carbon sources, significant temperature sensitivity, and unstable operation. Chemical precipitation methods (such as magnesium ammonium phosphate) are costly, and the resulting precipitates are difficult to dispose of.
This system employs electrochemical oxidation technology, efficiently converting ammonia nitrogen into nitrogen gas for removal through direct or indirect anode oxidation (generating strong oxidants such as active chlorine). Simultaneously, it can synergistically degrade COD and organic matter. No chemical reagents are required, secondary pollution is eliminated, no sludge is produced, and the electrode modules do not scale or clog during long-term operation. The equipment operates fully automatically, has a small footprint, and the effluent ammonia nitrogen consistently meets discharge standards.
Ammonia nitrogen treatment challenges points and solutions for this equipment
|
Challenges in Ammonia Nitrogen Treatment |
Electrochemical Solution |
|
Traditional stripping/stripping methods are energy-intensive and their efficiency is greatly affected by temperature and pH. |
Operates at ambient temperature and pressure, unaffected by air temperature, no pH adjustment required (efficiently treats both neutral and weakly alkaline water). |
|
Biological denitrification (A/O, etc.) requires large footprints, external carbon sources, and is inefficient in winter. |
Occupies only 1/5 to 1/10 the space of a biological treatment system, requires no carbon source, and operates stably year-round. |
|
Breakpoint chlorination requires large amounts of sodium hypochlorite, producing residual chlorine byproducts and increasing salinity. |
On-site electrolytic active chlorine production with high utilization rate; excess active chlorine can self-decompose or be treated with a simple aftertreatment system. |
|
Magnesium ammonium phosphate precipitation methods have high reagent costs, and the precipitates are difficult to dispose of resource-wise. |
Zero reagents, no sediment. |
|
High ammonia nitrogen levels are often accompanied by high salinity and high hardness, making conventional electrochemical equipment prone to scaling and failure. |
Special electrode operating mode, anti-scaling and anti-clogging, adaptable to complex water qualities. |
Working principle
High-ammonia nitrogen wastewater enters the electrochemical reactor after pre-filtration. Under the action of electrodes:
Direct electro-oxidation: Ammonia nitrogen is directly oxidized to nitrogen gas on the anode surface.
Indirect electro-oxidation (main pathway): Chloride ions (Cl⁻) are electrolyzed at the anode to generate active chlorine (Cl₂, HOCl, OCl⁻), which rapidly oxidizes ammonia nitrogen to nitrogen gas. The reaction formula is: 2NH₃ + 3HOCl → N₂ + 3Cl⁻ + 3H₂O. Chloride ions are not consumed in the reaction and can be recycled.
Co-removal of COD: Strong oxidizing substances such as hydroxyl radicals are simultaneously generated at the anode, which simultaneously degrade organic matter, avoiding interference from organic matter with the ammonia nitrogen oxidation efficiency.
The ammonia nitrogen in the treated effluent can be reduced to below 10 mg/L or even lower. Residual chlorine can be removed through simple post-treatment or used directly as disinfectant effluent.
Core advantages (for high ammonia nitrogen wastewater)
|
Advantages |
Description: |
|
Highly efficient ammonia nitrogen removal |
Ammonia nitrogen removal rate can reach 90%~99%, with effluent concentrations as low as 5~10 mg/L, stably meeting direct discharge or municipal sewer standards. |
|
No chemical reagents required |
No sodium hypochlorite, alkali, or carbon source is added; only electricity is required, eliminating the risks associated with chemical procurement and storage. |
|
No sludge production |
Ammonia nitrogen is directly converted to nitrogen gas, producing no chemical sludge or precipitates, resulting in no secondary pollution. |
|
Simultaneous COD degradation |
Synergistically oxidizes organic matter, reducing COD, suitable for complex wastewater with high ammonia nitrogen and high COD. |
|
Small footprint, high integration |
Only requires 1/10 to 1/5 of the floor space of biological denitrification, suitable for site-constrained renovation or new construction projects. |
|
Adaptable to a wide pH and temperature range |
Operates efficiently at pH 5~9 and 0~40℃, unaffected by season or location. |
|
Electrode does not scale or clog |
Special electrode coating and anti-scaling design allow for the treatment of high ammonia nitrogen wastewater with hardness and salinity, eliminating the need for frequent acid washing. |
|
Fully automatic operation |
PLC control automatically adjusts the current based on the influent ammonia nitrogen concentration, requiring unattended operation. |
