Electronic and electroplating wastewater
The electronics industry mainly covers circuit boards, electroplating/electrolysis, chips, large-scale integrated circuits, TFT/LCD processing, semiconductor manufacturing and other " High end, sophisticated, cutting-edge " fields, which require high-purity water in the production process and produce highly polluted wastewater during the production process, requiring reclaimed water reuse as a supplementary water source for production water to achieve energy saving and emission reduction.
A Guangdong electroplating industrial base treatment project
Treatment scale: 10000 m³/d
Commissioning time: February 2019
Raw water type: electroplating wastewater + domestic sewage
Treatment process: Raw water → conditioning tank → hydrolysis acidification tank → aeration tank → contact oxidation tank → intermediate tank → MBR → Clear tank → discharge/reuse
Use of produced water: discharge, circulating make-up water, desalinated raw water, industrial tap water replacement
