Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to an ammonia-phosphorus wastewater treatment reactor using polylactic acid and pyrrhotite. Background Art

[0002] Ammonia-phosphorus wastewater refers to wastewater containing high concentrations of ammonia nitrogen and phosphate discharged in industrial and agricultural production. This wastewater usually comes from industries such as fertilizer production, livestock and poultry breeding, aquaculture, and livestock and poultry manure treatment. Ammonia nitrogen and phosphate are the main pollutants in ammonia-phosphorus wastewater, and they are harmful to the environment and human health.

[0003] Ammonia nitrogen refers to ammonia nitrogen in water. It is a strong alkaline substance that is harmful to the environment and aquatic life. Phosphate is an important nutrient, but when its concentration is too high, it will lead to eutrophication of water bodies, causing problems such as excessive algae growth and water quality deterioration.

[0004] The discharge of ammonia and phosphorus wastewater has certain hazards to the environment and human health, so it needs to be effectively treated. At present, the commonly used methods for treating ammonia and phosphorus wastewater include biological methods, chemical methods and physical methods. Among them, biological method is a relatively common treatment method, which can degrade pollutants such as ammonia nitrogen and phosphate through microorganisms, thereby achieving the purpose of purifying wastewater.

[0005] Both polylactic acid and pyrrhotite have good adsorption properties and can reduce the concentration of pollutants in wastewater by adsorbing pollutants such as ammonia nitrogen and phosphate in wastewater. When the two work together, they can complement each other and improve the treatment effect of wastewater.

[0006] Most of the existing reactors for treating ammonia and phosphorus wastewater are liquid reactions, and few are reaction vessels that react through fillers. The efficiency of treating ammonia and phosphorus wastewater using polylactic acid and pyrrhotite in existing reactors is low, and the fillers are inconvenient to replace, resulting in poor reaction effects.
