News - Application Case of Emission Outlet in a Fiber Company in Jiangsu Province

A leading cellulose fiber manufacturer based in Jiangsu Province, recognized as a global industry leader, operates an extensive business network spanning key markets in Asia, Europe, and the Americas. Its products are widely utilized across diverse sectors including textiles, pharmaceuticals, and hygiene, serving as essential eco-friendly materials in modern daily life. The company’s cellulose fibers—renowned for their natural origin, comfort, and biodegradability—are progressively transforming the traditional textile industry. Compared to conventional cotton production, which demands substantial agricultural land and

water resources, the company’s fiber manufacturing process demonstrates superior sustainability by sourcing raw materials from responsibly managed fast-growing eucalyptus plantations. These tree species feature short rotation cycles and high carbon sequestration capacity, thereby establishing a renewable foundation for fiber production. Furthermore, cellulose fibers are fully biodegradable and offer an effective alternative to petroleum-based synthetic fibers such as polyester and acrylic. They exhibit notable performance advantages in premium non-woven applications, particularly in baby wipes and personal hygiene products.

As a benchmark enterprise in the industry, the company places environmental stewardship at the core of its strategic development. The production process generates wastewater containing key pollutants, including chemical oxygen demand (COD), ammonia nitrogen, total phosphorus, and total nitrogen. If discharged untreated, such effluents could significantly disrupt aquatic ecosystems. To uphold green development principles, the company has invested in an intelligent wastewater treatment system and deployed a suite of online monitoring instruments developed by Boxiang Environmental Technology Co., Ltd. at the main discharge outlet of its wastewater treatment facility, establishing a real-time, high-precision water quality monitoring network. The equipment procured includes:
• CODG-3000 Chemical Oxygen Demand Online Analyzer: Utilizing ultraviolet absorption technology, this instrument enables high-accuracy, continuous monitoring of COD concentrations within a range of 0–5000 mg/L, suitable for high-strength industrial wastewater.

• NHNG-3010 Ammonia Nitrogen Online Analyzer: Based on salicylate spectrophotometry, it features automatic calibration and self-diagnostic capabilities, ensuring long-term data stability and reliability.

• TPG-3030 Total Phosphorus Online Analyzer: Employing molybdenum blue spectrophotometry, it supports a detection range of 0–10 mg/L, effectively accommodating fluctuating water quality conditions.

• TNG-3020 Total Nitrogen Online Analyzer: Using persulfate digestion coupled with UV spectrophotometry, it achieves automated total nitrogen analysis with over 98% digestion efficiency.

• pHG-2091Pro pH Online Analyzer: Equipped with intelligent temperature-compensated electrodes, it delivers measurement accuracy of ±0.01 pH and supports multi-parameter integrated monitoring.

This intelligent monitoring system enables digitalized management of the entire wastewater treatment process, offering functionalities such as real-time data acquisition, anomaly alerts, and trend analysis. Environmental operators can remotely monitor operational status via a centralized control platform. Monitoring data is seamlessly transmitted to the Suqian City Environmental Protection Bureau in Jiangsu Province, compliant with the HJ212-2017 protocol standard. The system’s quality assurance procedures have been officially verified by the local environmental authority. All instruments hold the China Environmental Protection Product Certification (CCEP), ensuring accurate and reliable measurement outcomes.

The implementation of this system has substantially enhanced the company’s environmental management performance: wastewater treatment efficiency has improved by 25%, chemical reagent consumption has decreased by 30%, and annual operational costs have been reduced by more than 2 million RMB. Moreover, the rigorous emissions monitoring framework ensures 100% compliance with discharge standards, contributing positively to regional water quality improvement. This case exemplifies the commitment of multinational enterprises to achieving carbon neutrality and offers a scalable model of green manufacturing for the global textile sector.
