Abstract :
Upgrading of a landfill leachate treatment plant (LLTP) to meet capacity expansion as well as the new discharge standards is addressed. According to the upgrading scheme, the hybrid membrane processes based on membrane bioreactor (MBR) technology are adopted in the plant. A reverse osmosis (RO) unit is installed in the original facility to polish the effluent for reclaimed water reuse, and a new system combined two-stage MBR unit with two-stage nanofiltration (NF) unit is built to enhance treatment capability for additional load from capacity expansion. The results show that the treatment capacity of the plant has increased from 200 to 900 m3/d, and the effluent of the upgraded LLTP has met the new discharge standards.
