Steel industry wastewater, characterized by complex composition, often presents challenges such as high hardness, scaling tendencies, and poor biodegradability. Among these, achieving stable chemical oxygen demand (COD) compliance remains a persistent industry pain point. Conventional catalytic oxidation technologies rely heavily on catalysts, frequently suffering from efficiency degradation due to catalyst deactivation and secondary pollution, leading to elevated operational and maintenance costs.

Recently, leveraging its mature expertise in high-difficulty industrial wastewater treatment, Hanqi Environment successfully applied its proprietary Ozone Fluidized Bed Technology in a major steel industrial park wastewater treatment project in Yingkou, Liaoning Province. The project has now entered the critical equipment installation phase, marking a significant milestone in Hanqi's capability to deliver stable COD compliance for complex steel wastewater.

Why Hanqi's Ozone Fluidized Bed Technology Excels in Steel Wastewater Treatment?

High-Efficiency Degradation of Refractory COD:

The technology’s innovative fluidized design dramatically enhances ozone-water mass transfer, enabling efficient oxidation and removal of non-biodegradable COD. This ensures long-term stable effluent quality, even under increasingly stringent environmental regulations.

Catalyst-Free Operation for Enhanced Reliability:

Unlike traditional catalytic oxidation, Huanqi’s solution eliminates dependence on deactivation-prone catalysts, fundamentally avoiding efficiency fluctuations and secondary contamination risks. The system operates with greater stability, simpler maintenance, and lower long-term costs.

Modular Design Saves Space & Investment:

The highly integrated modular system reduces footprint by over 40% compared to conventional solutions, significantly cutting civil works and upfront capital expenditures while delivering tangible value to clients.

Hanqi's third-generation Ozone Fluidized Bed Technology has been proven across dozens of projects in petrochemical and coal chemical industries, demonstrating consistent performance. Its successful adaptation to the steel sector not only expands the technology's applicability but also underscores Huanqi's integrated expertise in tackling steel wastewater's core challenges: COD compliance and cost control.

Aligned with the steel industry's urgent needs for green transformation and sustainable production, Huanqi Environment remains committed to advancing high-difficulty wastewater solutions. Through core technologies like the efficient, stable, and cost-effective Ozone Fluidized Bed, Huanqi delivers practical compliance and emission-reduction strategies, empowering steel enterprises to achieve both environmental compliance and operational excellence.
