On June 11, the concentrated water treatment unit of the water system recycling device of the Xinjiang Tianye Phase I 600,000 tons/year coal-to-ethylene glycol project contracted by Donghua Technology produced qualified recycled water, and all process indicators were up to standard
.
The completion of this node marked the completion of the commissioning of the concentrated water treatment unit of the project's water system recycling device, and laid a solid foundation for the subsequent commissioning of the membrane concentration unit and other related processes
.
The concentrated water treatment unit is mainly composed of 6 sections of concentrated water ozone oxidation tank, concentrated water aerated biological filter, multi-media filter, concentrated water ultrafiltration, concentrated water reverse osmosis and supporting dosing system.
The concentrated water treatment unit mainly processes Concentrated water produced from reclaimed water reverse osmosis, with an inlet water scale of 300m3/h
.
Nissan's qualified water reuse is 3600m3, and the system recovery rate is ≥50%
.
Since the water treatment unit produced water on June 3, 2020, the Xinjiang Tianye Project Department of Donghua Technology has reasonably and effectively arranged the pipeline flushing of the concentrated water treatment unit, and organized manpower to complete the concentrated water ultrafiltration membrane and concentrated water in strict accordance with the equipment process installation requirements.

.
In order to ensure the smooth commissioning work, the project team members organized a commando team to plan in advance, take precautions, and solve the emergent problems on the spot as soon as possible, which truly reflects the "Donghua speed" of the project construction
.
In the next step, the project department will debug the membrane concentration section and waste salt post-treatment section of the water system recycling device.
The commissioning is planned to be completed on June 18, when the entire water system will achieve "zero" discharge
