answer:
Yes, polyacrylamide can be used in electronic circuit board wastewater treatment.
During the production process of electronic circuit boards, a large amount of wastewater is generated. These wastewaters contain various harmful substances, including heavy metal ions, organic solvents, acids and alkalis, etc. For the treatment of these wastewaters, the use of polyacrylamide is a feasible method.
Polyacrylamide can effectively remove suspended solids and heavy metal ions in wastewater. Through flocculation and sedimentation, suspended solids and heavy metal ions can be combined with polyacrylamide to form larger particles, which can be separated from wastewater. In this way, harmful substances in wastewater can be effectively reduced, and the purpose of purifying water quality can be achieved.
