Introduction: In recent years, the pharmaceutical industry has become a high-incidence field of environmental pollution incidents. From Harbin Medicine to Hisun, excessive discharge of waste water has become a common occurrence of enterprises. The reason is that, on the one hand, the cost of environmental protection violations is lower than the cost of environmental treatment. On the other hand, the current traditional wastewater treatment technology is difficult to meet the high concentration and difficult degradation characteristics of pharmaceutical wastewater. So for enterprise users, seeking low-cost and high-efficiency pharmaceutical wastewater treatment technology has become a top priority. For environmental protection companies, it has become an urgent need to promote advanced practical technologies developed by manpower and materials. In view of this demand, Guteng Environmental Protection Network and the environmental protection company jointly build a pharmaceutical wastewater treatment topic, and launch the most economical and practical technology to help customers.
