[0002] With the acceleration of industrialization, various factories and manufacturing industries have developed rapidly. During the production process, large amounts of wastewater containing various pollutants are discharged. If this wastewater is discharged directly into the environment without treatment, it will cause serious pollution to the soil, water sources, and air, disrupting the ecological balance and threatening human health and biodiversity.

[0003] In the prior art, when treating wastewater generated in industrial production, the compressed air of the industrial wastewater treatment system is usually designed as an independent compressed air system. When treating high-concentration organic wastewater in the biological pool or wastewater containing toxic and harmful substances, the compressed air system is required to provide sufficient air to ensure the biological reaction efficiency of the wastewater treatment in the biological pool. The incinerator can completely decompose organic matter or harmlessly treat toxic and harmful substances through high-temperature combustion. However, when the compressed air system in the incinerator is operating normally, the air compressor pressure drops to 0.8MPa to unload, and the pressure drops to 0.65MPa to reload. The two independent compressed air systems work separately, and the systems are not optimized and integrated, resulting in increased system power consumption and maintenance costs, causing waste of resources.

[0004] Therefore, it is necessary to propose a garbage incinerator and industrial wastewater treatment system to solve the above problems. Utility Model Content
