1. High removal efficiency, it can realize the standard discharge of high concentration ammonia nitrogen wastewater in a single treatment (ammonia nitrogen separation from 90000mg/L to less than 15mg/L)
Second, the concentration of high, large amount of ammonia gas can be recycled (ammonia water, ammonium sulfate, ammonium chloride) to the production line, recycling economy, to avoid secondary pollution
Third, it also has a high removal efficiency of COD
Low processing cost
V. simple process, simple operation and stable operation
Their high concentration of ammonia nitrogen wastewater from the production workshop to the high concentration of ammonia nitrogen wastewater after adjusting with the adjust pool of water, then quantitative pump into the high concentration of ammonia nitrogen wastewater collection pool, set within the pool by adding the lime powder or liquid alkali, adjust the pH value of the high concentration of ammonia nitrogen wastewater to suitable for ammonia separation of pH value, easy to take off the further processing of ammonia washing tower is ammonia nitrogen wastewater (NH3 - N 15 mg/L) or less emissions standards, at the same time, quantitative dosing efficiency ammonia additives, mix with water, accelerate the free NH3 conversion and generated in the waste water.
& have spent
If there are other pollutants in the treated wastewater, they can be discharged directly if there are no other pollutants.
Due to the high concentration of NH3 in the gas phase, further treatment is required.
The company has two treatment methods:
1. Spray absorption. The separated NH3 is fed into the absorption tower, and the dilute sulfuric acid solution is used for multi-stage spray absorption.
Ammonium sulfate crystals can be directly recycled or sold as by-products.
2. High efficient oxidation and decomposition technology: electron - hole pairs are generated on high efficient oxidation and decomposition catalyst materials through special light waves of a certain wavelength, which react with water (H2O) and oxygen (O2) adsorption on the surface to generate hydroxyl free radicals (OH-) and superoxide ion free radicals (O2-, 0-) with very active oxidation waves.
It can reduce ammonia gas, hydrocarbons, other organic compounds and VOC organic compounds into carbon dioxide, water, nitrogen and other non-toxic and harmless substances. It can also play the role of disinfection and sterilization while removing odor. Because there is no additive in the process of efficient oxidation and decomposition, it will not produce secondary pollution.
