Optoelectronic Display New Materials Industrial Park Project

The Qingdao Optoelectronic Display New Materials Industrial Park project focuses on the production and R&D of upstream core materials and high-end intelligent equipment for the optoelectronic display industry. During the production process, such industrial parks may use various chemicals and generate wastewater containing specific pollutants. Therefore, water quality monitoring is crucial to ensure environmental safety and compliant discharge.

Water Quality Monitoring Indicators

Physical parameters: such as temperature, color, turbidity, suspended solids (SS), etc.

Chemical parameters: pH value, dissolved oxygen (DO), chemical oxygen demand (COD), five-day biochemical oxygen demand (BOD₅), ammonia nitrogen (NH₃-N), total phosphorus (TP), total nitrogen (TN), heavy metal content (e.g., cadmium, mercury, lead, etc.).

Specific pollutants: Depending on the production process characteristics of the enterprises within the park, monitoring of specific organic compounds or other special pollutants may also be required.

Microbiological indicators: such as coliform bacteria count, etc.

Monitoring Frequency and Methods

Determine the monitoring frequency for different pollutants in accordance with national and local environmental regulations. Key pollutants may require more frequent monitoring, e.g., daily or weekly; routine indicators may be monitored monthly or quarterly.

Use online monitoring equipment for real-time monitoring of key indicators, and conduct regular in-depth testing through laboratory analysis.

Laws, Regulations and Standards

All monitoring activities must comply with the Integrated Wastewater Discharge Standard (GB8978-1996) as well as other relevant local regulations and industry standards.

Particularly for high-tech industries such as optoelectronic display material manufacturing, there may be additional stringent environmental requirements and discharge standards.
