Fluidized bed Fenton technology is a high-performance organic wastewater treatment technology. Compared with other technologies, this technology has the advantages of high performance and low operating costs. After the reaction, the waste sludge product is converted into crystalline form, except that the cost of sludge treatment can be reduced. At the same time, it can be recycled and reused (such as the production of magnets, phosphorus and arsenic adsorbent materials, etc.), which is environmentally friendly. To stabilize the crystallization conditions, the structure and composition specifications of the tank have been developed with a unique design. The reaction tank has the best conditions for high quality and high efficiency. The tank body is made of SUS316L, which is highly resistant to corrosion, and the main device is open type. The hole location is custom designed, in accordance with the actual installation land needs at the construction site. The first stage of system operation development is from manual monitoring activities, to the addition of PLC automatic control. , automatic adding and dosing of wastewater and medicine, online monitoring of water quality, abnormal alarm device for peripheral equipment, etc. Adjusting system parameters in a system-automated manner is difficult to simulate in hardware and software. For countries with strict wastewater control standards (Mainland and Vietnam), this technology has been widely applied and wastewater standards must be the trend, highly competitive value of this technology will become more significant.
