Domestic sewage mainly consists of various detergents used in urban life, as well as sewage, garbage, feces, etc. Most of it is composed of non-toxic inorganic salts. Domestic sewage contains a relatively large amount of nitrogen, phosphorus and sulfur, and there are many pathogenic bacteria in it. The reason for the high ammonia nitrogen content in domestic sewage is that nitrogen-containing organic matters such as food residues in domestic sewage produce free ammonia and ammonium ions under the decomposition of microorganisms. The ammonia nitrogen in domestic sewage generally comes from the products formed by the action of microorganisms on nitrogen-containing organic matters in domestic sewage. Generally, the ammonia nitrogen index also represents the degree of water body pollution. Controlling ammonia nitrogen well can effectively reduce the risk of water body eutrophication.
Ammonia nitrogen refers to the nitrogen present in water in the forms of free ammonia (NH3) and ammonium ions (NH4+). The ammonia nitrogen removal agent is a new type of chemical agent, which has the functions of catalyzing and decomposing ammonia nitrogen in sewage. It can rapidly convert the ammonia nitrogen in wastewater into harmless gases. After adding the agent, the ammonia nitrogen in the wastewater will react to form water-insoluble nitrogen, nitrogen dioxide, nitric oxide and water, thus achieving the purpose of removing ammonia nitrogen.
After treatment, the ammonia nitrogen content in the wastewater of most companies is not too high, and it is mostly around 20-80 PPM. To reduce this part of ammonia nitrogen to below 10 PPM or even lower, it is necessary to add an ammonia nitrogen removal agent for degradation, so as to make the ammonia nitrogen content meet the national discharge standards. The ammonia nitrogen removal agent has a high reaction efficiency. It can rapidly degrade the ammonia nitrogen in sewage, fulfilling the requirements for purifying the water quality. It also has the auxiliary functions of removing COD and decolorizing. It can complete the reaction process without residues and has a high removal rate. It is also applicable to the treatment of high ammonia nitrogen wastewater generated in industries such as printed circuit boards, electroplating, electronics, textiles, dyeing and printing, leather processing, fertilizer plants, slaughterhouses, aquaculture farms, and municipal sewage treatment.
