Advanced Treatment Technology for Pharmaceutical Wastewater

1. Anti scaling technology for wastewater concentration process MVR evaporation is a new technology for wastewater treatment, which prevents scaling and descaling in preheaters and heat exchangers. 2. High salt wastewater treatment technology: Separation, purification, and reuse technology for high salt wastewater containing inorganic impurities such as sodium sulfate, calcium sulfate, sodium chloride, sodium phosphate, and silicate, as well as some organic substances. 3. Anaerobic treatment technology for high sulfate wastewater is aimed at anaerobic treatment technology for wastewater with sulfate content greater than 2000mg/L. 4. The main problems in the pre-treatment technology of high concentration and difficult to degrade wastewater in the pharmaceutical industry are the unstable COD, NH3-N, total nitrogen, total phosphorus, and even dichloromethane, TOC and other indicators that meet the standards. The sludge problem is also a problem when starting to assess the waste salt and other indicators. The current problems in wastewater treatment in the pharmaceutical industry mainly include unstable COD, NH3-N, total nitrogen, total phosphorus, and even the assessment of indicators such as dichloromethane and TOC after the standard is raised, as well as sludge problems. High salt wastewater, high ammonia nitrogen wastewater, high SS wastewater, and high concentration wastewater are finally reused through pre-treatment technology, anaerobic technology, secondary aerobic treatment technology, and advanced treatment technology
