An Application Case Study of the Discharge Monitoring System at a Biotechnology Company in Shanghai

A biotechnology company based in Shanghai was established in 2018. Its business operations encompass a wide range of activities, including technical services, technical development, consulting, exchange, transfer, and promotion; wholesale of edible agricultural products, computer software, hardware, and related equipment; sales of instruments and meters; import and export of goods and technologies; and distribution of bio-based materials.

To enhance environmental monitoring and ensure compliance with discharge regulations, the company has procured the following online analytical instruments:

- CODG-3000 Online Automatic Chemical Oxygen Demand (COD) Analyzer
- NHNG-3010 Online Automatic Ammonia Nitrogen Monitor

- pHG-2091Pro Online Automatic pH Analyzer 

The COD analyzer is designed to measure the concentration of organic matter in wastewater by determining the chemical oxygen demand. This enables wastewater treatment facilities to assess pollutant levels accurately and evaluate the potential environmental impact of discharged effluents.

The ammonia nitrogen analyzer monitors the concentration of ammonia nitrogen in water bodies. It supports continuous tracking of nitrogen discharge, allowing operators to evaluate the efficiency of treatment processes and prevent excessive ammonia nitrogen from being released into the environment.
The pH analyzer measures the acidity or alkalinity of wastewater in real time. By maintaining optimal pH levels, it ensures the stability and effectiveness of the treatment process while safeguarding environmental quality.

At the company’s wastewater discharge outlet, online analyzers for COD, ammonia nitrogen, and pH—manufactured by Shanghai Boqu Instrument Co., Ltd.—have been installed and integrated into the monitoring system. Through continuous operation of these devices, operation and maintenance personnel can promptly detect fluctuations in water quality parameters, identify operational anomalies, and implement corrective actions in a timely manner. This comprehensive monitoring approach ensures that all discharges comply with regulatory standards and contribute to sustainable environmental management.
