Abstract
A semiconductor process wastewater treatment system and a semiconductor process wastewater treatment method using the same are disclosed. The disclosed semiconductor process wastewater treatment system may comprises: a processing unit configured to receive semiconductor process wastewater and treats the semiconductor process wastewater through a plurality of operations; and a membrane filtration tank arranged separately from the processing unit, the membrane filtration tank having a ceramic nano-membrane for filtering the semiconductor process wastewater which has passed through the processing unit, wherein the ceramic nano-membrane may include a carbon-based nano-material. The ceramic nano-membrane may include a graphene-based nano-material as the carbon-based nano-material.
