二、Main monitoring project
The main monitoring project of wastewater of Gushen Biotechnology Group Co., Ltd. is COD.
Third, monitoring points:
According to the environmental impact assessment report and its approval and environmental monitoring management requirements, one monitoring point is set. It is located at the northwest corner of the constructed wetland and is equipped with automatic monitoring equipment for real-time monitoring throughout the day. The monitoring points are as follows:

四、Wastewater monitoring method and instrument

The Gushen Group wastewater is monitored by a combination of manual monitoring and automatic monitoring.

 1、Automatic monitoring

Entrusted third-party testing agency Dezhou Huayun Environmental Protection Technology Co., Ltd. to transport our company's wastewater monitoring equipment

2、Manual monitoring 

In the case that the automatic monitoring equipment is in the process of overhaul and abnormal operation, manual monitoring is adopted, and manual monitoring is carried out by self-administered monitoring. The sewage treatment station is equipped with an independent laboratory, and the instrument is fully equipped and standardized; 2 technicians are equipped, and all have obtained the certificate issued by the environmental protection department.

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.
