Guangdong Tailwater Concentrated Deep Purification Treatment Station

The Tailwater Centralized Deep Purification Treatment Station Project in Jiangmen, Guangdong, focuses on the deep purification of tailwater generated from industrial zones to ensure that the final discharged water quality meets environmental standards. The water quality monitoring for such projects includes the following aspects:

Water Quality Monitoring Indicators

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

Chemical indicators: such as 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., chromium, mercury, lead, etc.), etc.

Microbiological indicators: such as coliform bacteria count, etc.

Monitoring Methods

Online monitoring: For some key parameters, such as pH value, DO, COD, and ammonia nitrogen, online monitoring equipment may be used for real-time monitoring.

Regulations and Standards

Water quality monitoring must comply with relevant national and local regulations and standards, such as the Integrated Wastewater Discharge Standard (GB8978-1996), as well as stricter local standards for specific industries or standards set by enterprises themselves.
