Zangge Potash Wastewater Treatment System Fully Completed

With the official commissioning of the final set of wastewater treatment equipment in the plant, the company has achieved the important goal of comprehensive wastewater treatment across the entire facility. After three years of continuous installation and commissioning, the three wastewater treatment systems located in the lake area were fully launched on April 2, successfully completing the task of domestic wastewater treatment. Prior to this, the installations and commissioning of the systems in Workshop No.1 and Workshop No.8 had already been completed.

The new wastewater treatment system adopts advanced MBR (Membrane Bioreactor) technology, capable of effectively treating 350 cubic meters of domestic wastewater generated daily in the living area.

The system has a daily treatment capacity of 270 cubic meters, reaching 80% treatment efficiency, with an annual total treatment volume of up to 98,550 cubic meters. The treated water achieves a 100% compliance rate in water quality standards.

The newly completed wastewater treatment system integrates efficiency and stability, with a process flow covering five core stages:

Collection Tank: Wastewater is first collected and stored here, ensuring stable flow for subsequent treatment.

Anaerobic Tank: Anaerobic bacteria break down macromolecular organic matter. Combined with intermittent nitrification liquid and sludge reflux, treatment efficiency is optimized.

Aerobic Tank: Aerobic microorganisms and active bacteria further degrade organic matter in the wastewater, while simultaneously completing nitrification reactions to effectively remove ammonia nitrogen and phosphorus.

Membrane Tank: MBR membrane modules accurately separate microorganisms and suspended solids, achieving solid-liquid separation. The intelligent backwash program ensures filtration efficiency.

Clean Water Tank: After a brief retention, treated water meets reuse or discharge standards, enabling water resource recycling.

The system innovatively integrates biological treatment with membrane separation technology. With real-time monitoring of water volume, water quality, and membrane operation status, it dynamically adjusts aeration levels and cleaning frequency to ensure stable and efficient operation. In addition, sufficient liquid-level regulation space and strict control of early-warning indicators provide effective responses to water quality fluctuations, ensuring 100% compliance of treated water quality.

From the depths of the salt lake to clear flowing waters, Zangge Potash upholds environmental responsibility through technological innovation. Looking ahead, the company will continue to strengthen internal management, advance environmental technology upgrades, and serve as a solid backbone for the company’s green development.
