Our company provides sewage treatment services for Sichuan Yanyi New Materials Co., Ltd. The original sewage treatment equipment was not effective in treating workshop-level production wastewater with complex composition, high salt content and seriously exceeded chemical oxygen demand (COD). After technical personnel improved the sewage treatment equipment, they first used advanced oxidation technology (iron-carbon micro-electrolysis + Fenton) to pre-treat the high COD wastewater, and then mixed the treated wastewater with the rest of the wastewater to effectively reduce the concentration of organic matter, and finally treated it by A/O+MBR process. This optimization greatly improved the COD removal rate and achieved the standard discharge of wastewater. This improvement not only effectively solved the customer's problems in wastewater treatment efficiency and water quality, but also met environmental protection requirements. With its stable and efficient treatment performance, it has won customer recognition. Since the cooperation began, the cooperative relationship between the two parties has continued to be stable.
