Tar Refining Sodium Sulfate Wastewater Treatment Unit Efficient Purification Solutions¹

Product DescriptionAs one of the three major synthetic thermosetting resins, phenolic resin has experienced a history of more than 100 years and has been widely used as molding compound, adhesive, coating, foam, ink, etc. The concentration of organic pollutants such as phenol, aldehyde and alcohol in phenolic resin wastewater is very high, which is relatively difficult to treat.Through the combination technology, our company first recycles the phenol in the water, then removes the formaldehyde in the water, and then undergoes biochemical treatment to reduce the phenol and aldehyde in the wastewater to the discharge standard specified by the state.According to the latest requirements of <Emission Standard of Pollutants for Synthetic Resin Industry GB31572-2015>: The maximum phenol content in the first-level emission standard shall not exceed 0.3 mg/l, and the maximum phenol content in third-level emission standard shall be 0.5 mg/l; The formaldehyde content shall not exceed 1mg/l in the first-level emission standard and 2mg/l in third-level emission standard.Oxidation method: Common oxidation methods include reagent oxidation, ozone oxidation, micro-electrolytic oxidation, strong electrolytic oxidation, photocatalytic oxidation, wet oxidation, ultrasound/H2O2method,ClO2 oxidation, etc.Biochemical method: phenol and aldehyde are used as nutrients for microorganisms to remove phenol and aldehydes in wastewater through biological self-metabolic decomposition.Hubei Sanli Fengxiang Technology Co., Ltd. is a standardized enterprise integrating environmental protection solvent production, tower internals design and processing and foreign trade, mainly providing complete production technology of chemical products, chemical separation solutions and wet oxidation treatment of high-salt wastewater. The core team of the company has many years of experience in complete sets of chemical production technology and production equipment, and can provide domestic and foreign customers with serial chemical technology and equipment. These technologies include hydrogen peroxide, acetate series, MMA, polyoxymethylene dimethyl ether (PODEn), anhydrous formaldehyde, glycerol-based epichlorohydrin, and wet oxidation treatment of wastewater.In terms of chemical separation solutions, the company takes Tianjin University as the technology research and development platform, and can provide customers with one-stop services from laboratory scale test to industrial production. The core members have multi-professional education backgrounds such as chemical machinery and chemical process simulation, and have accumulated a lot of engineering experience and proprietary technology, especially in reactive distillation, vacuum distillation, coupled distillation, etc. The successful application of a number of achievements has created huge economic benefits for customers……The company adheres to the core values of "never forget the original intention, innovate and develop, pursue excellence, be sincere to users, and contribute to society", adheres to the concept of "what customers need is what we want; brand is gold, honor is supreme", strives to provide customers with excellent services, and aspires to become the industry's leading one-stop solution expert.Q1.
