Recently, the wastewater treatment and reuse pre-treatment system of the PetroChina Dushanzi Petrochemical Tarim Phase II Ethylene Project successfully passed acceptance and was officially delivered. Hanqi Environment provided the full-process process package for the reuse pre-treatment system. This marks the second time Hanqi Environment has served this client following the Phase I project, and the execution process received unanimous recognition from both the owner and the general contractor.

Located in the Gobi Desert, the Tarim Phase II Ethylene Project faced tight schedule and high coordination requirements. As the general contractor, China Kunlun Contracting & Engineering Corporation demonstrated professional and efficient engineering management capabilities in constructing core facilities including the wastewater treatment plant, providing solid guarantees for the smooth progress of the project. The owner unit gave full trust and support, affirming the project's construction achievements. Close collaboration among all parties ensured that the project passed acceptance and was delivered on schedule.

Addressing the challenges of high-hardness and high-alkalinity wastewater prone to scaling and blockage, and the difficulty of achieving long-term stable operation, Hanqi Environment integrated core technologies including simultaneous hardness and silica removal, ozone oxidation, aerated biological filter, and advanced filtration, supported by proprietary anti-scaling patented technology to ensure long-term continuous and stable operation of the system. During execution, the Hanqi team maintained close communication with the owner and general contractor, strictly following construction drawings, providing reliable support for the stable operation of the system.

This successful delivery once again validates Hanqi Environment's technical strength in deep treatment and reuse of petrochemical wastewater, and reflects the company's commitment to contract fulfillment and delivery under its "long-termism" philosophy. Going forward, the company will continue to focus on the field of high-difficulty industrial wastewater treatment, concentrating on client pain points, pragmatically advancing technology application, and providing solid guarantees for the green, low-carbon, and high-quality development of petrochemical enterprises.
