Abstract

The invention discloses an integrated reactor for deeply treating vitamin C wastewater and a method of the integrated reactor, and belongs to the technical field of wastewater treatment. The reactor mainly comprises an integrated reactor, a wastewater raw liquid box, a chlorine ion detecting device and an extraction agent storing box, wherein the integrated reactor is divided into a biological reaction unit and a salinity adjusting unit, the interior of the biological reaction unit is divided into a sedimentation area, an anaerobic biological area, a transitional area and an aerobic biologicalarea from the bottom to the top; the anaerobic biological area and the aerobic biological area are separated through a permeable membrane 1 and a permeable membrane 2 respectively, and chlorine ionsin the wastewater are extracted by utilizing a membrane, so that the microbial activity is prevented from being affected by the excessively-high concentration of the chlorine ions, and the wastewatertreatment efficiency is reduced; an extraction agent organic phase can be post-treated to obtain by-product ammonium chloride for recycling; and in short, the reactor provided by the invention has excellent treatment effect for treating the high-salinity wastewater, discharges water stably, is green and environmentally friendly, and has high economic benefits.

Description

technical field [0001] The invention belongs to the technical field of wastewater treatment, and in particular relates to an integrated reactor and method for advanced treatment of vitamin C wastewater. Background technique [0002] Vitamin C (also known as L-ascorbic acid, referred to as VC), is a nutritional enhancer and functional antioxidant needed by human beings. It is currently the most widely used vitamin in the world, with the largest production and sales. It is widely used in medicine, food and beverage , feed and other industries, and it is also one of the varieties with the largest annual output and export volume of Chinese pharmaceutical companies. Since 1998, the export volume of vitamin C has increased year by year. In 21 years, the export volume reached 110,000 tons, accounting for more than 9% of the global demand, and most of the output came from 5 domestic pharmaceutical companies. China has become a veritable vitamin C producing country. [0003] Domest...
