              五、Frequency of monitoring 

              The Gushen Group implements 24-hour online automatic continuous monitoring of COD and wastewater flows. The COD is monitored once a day by manual monitoring when the automatic monitoring equipment is under maintenance and abnormal operation.

              六、Execution of emission standards and their limits

              Implementation of emission standards: Shandong Province Haihe River Basin comprehensive discharge standards for water pollutants (DB37 675-2007) Table 4 secondary standard and its revised single Lu quality supervision issued [2011] No. 35: COD ≤ 60mg / L.

              七、Monitoring quality control measures

              1. Automatic monitoring of wastewater pollutants: Calibration and maintenance of automatic monitoring equipment in accordance with the Technical Specifications for Acceptance of Online Monitoring System for Water Pollution Sources (Trial) (HJ/T 354-2007).

              2. Recording requirements: The operation and maintenance records of the automatic monitoring equipment, and the contents of all kinds of original records should be complete and signed by relevant personnel for three years.

              3. Manual monitoring and monitoring Strictly implement the “Technical Specifications for Environmental Monitoring” and “Methods for Monitoring and Analysis of Water and Wastewater” to implement quality assurance throughout the entire process. Laboratory personnel are certified to work.
