作者介紹
Through literature review, limited space in the factory
and consideration of construction costs, we chose to use
a physical and chemical treatment system(ACF tower unit
in series membrane equipment unit) for planning and
build an efficient AOR organic wastewater recovery and
treatment system ; improve LSS The quality of the water
supply reduces the TOC in the water from 10.0ppm to
3.1ppm. The water quality of the scrubber was improved.
The LWSC NMHC outlet concentration was improved by
93%(avg. 9.24 to 0.54ppm), effectively reducing the total
NMHC emissions at the chimney outlet by 0.50Ton/Year,
improving the factory chimney emission quality, meeting
the water quality refining requirements for air sewage
equipment, and reducing air pollution.
