Abstract

The invention discloses an ion exchange resin wastewater treatment method, and aims to solve the technical problems of low treatment efficiency, unstable effect and environmental pollution in an ion exchange resin production wastewater treatment process. According to the method disclosed by the invention, effluent of a pretreatment device enters a biochemical treatment device, effluent of the biochemical treatment device enters a post-treatment system, all parts have clear functions and perform respective functions, the process composition is reasonable, physicochemical treatment and biochemical treatment are orderly and organically combined, and the functions of all units are maximized; through the combined action of pretreatment, the biodegradability of the wastewater is improved; and different organic matters are removed by utilizing the advantages of different strains in the biochemical treatment device. The method provided by the invention can effectively perform advanced treatment on the sewage, so that the COD (Chemical Oxygen Demand) of the final effluent is reduced to be below 200mg / L, and the environmental protection requirement is met; the treatment system is convenientto operate and manage, stable in process and low in investment and operation cost; and the treatment efficiency is high, the treatment effect is stable, and the method is economical and reasonable.

Description

technical field [0001] The invention relates to the technical field of industrial wastewater treatment, in particular to an ion exchange resin wastewater treatment system and method. Background technique [0002] Ion exchange resin is a polymer compound with functional groups, network structure and insolubility. The type of chemically active groups in the resin determines the main properties and categories of the resin, which are mainly divided into two categories: cationic resins and anionic resins. [0003] Ion exchange resins are used in a wide range of fields. In the field of water treatment, the demand for ion exchange resins accounts for about 90% of the output of ion exchange resins. At present, the largest consumption of ion exchange resin is used in the pure water treatment of thermal power plants, followed by atomic energy, semiconductor, electronic industry, etc., and then food industry, pharmaceutical industry; in Chinese medicine, synthetic chemistry and petroc...
