Hubei Tuoyu Hydroelectric Technology Co., Ltd

Through regular water quality monitoring, enterprises can evaluate the efficiency of their wastewater treatment systems, ensure that discharges meet national and local environmental standards, and thereby avoid environmental pollution and potential legal risks.

Monitoring Objectives

Environmental protection: Ensure that wastewater is treated to meet standards before discharge, reducing pollution to natural water bodies.

Compliance verification: Comply with national and local environmental laws and regulations.

Process control: Monitor the quality of water used in production processes to ensure process stability and product quality.

Common 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, etc.

Microbiological indicators: coliform bacteria count, etc., which are particularly important for industries such as food processing and pharmaceuticals.

Monitoring Frequency and Methods

Monitoring frequency is determined based on the enterprise's industry type, wastewater characteristics, and requirements of local environmental protection authorities. 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.
