    Technical introduction

    Our company's invention patent (Patent No. 201810180806.1) was transformed and applied to pharmaceutical wastewater treatment to achieve high TOC and high salt separation and TOC and total nitrogen removal, and was successfully used in a Sino-foreign joint venture pharmaceutical industry.

    Introduction to the principle

    The nature of antibiotic wastewater is high COD, high salt content, complex composition, and high color. The process route selects filtration + concentration + evaporation technology + biochemical treatment. Filtration refers to removing suspended solids >0.1um in the water through multi-stage filtration. Concentration refers to reducing the salt content in the wastewater through membrane technology and concentrating it to more than 15%. The fresh water enters the biochemical system. , concentrated water enters the evaporation system, and evaporation means that the concentrated high-salt water continues to concentrate until it crystallizes to produce crystals. Biochemical treatment mainly uses concentrated fresh water and evaporated condensed water, relying on microorganisms to degrade pollutants in sewage.

    Technical features

    Multi-stage filtration has high efficiency in removing suspended solids; the concentration unit is a special separation membrane developed based on the properties of wastewater, which is suitable for salt concentration under high COD; the evaporation unit cooperates with the technologically improved process to extend the evaporation time and system stability.
