In November 2016, our company and Shandong Hongjitang Pharmaceutical Group reached a cooperation agreement. The comprehensive pharmaceutical park adopts the “one enterprise, one management” governance model to monitor COD, ammonia nitrogen, flow and other indicators online, and can control pollution sources from the source. Control the problem of excessive emissions from upstream enterprises. The water quality index after deep treatment is: COD=45mg/L, BOD=1045mg/L, total nitrogen=15mg/L, total phosphorus=0.5mg/L, PH:6-9, SS=10mg/L. The emission standard meets the water quality of the key protected areas in the “Comprehensive Emission Standards for Water Pollutants in the Xiaoqing River Basin of Shandong Province” (DB37/656-2006).
