摘要：

This study describes the design and upscaling of an on-site regenerable adsorbent fixed bed of Fe-loaded MFI zeolite for removal of chlorinated hydrocarbons (CHCs) from contaminated groundwater from laboratory studies to pilot scale. The zeolite has an excellent adsorption performance for the hydrophilic CHCs and can be regenerated on-site by flushing with H2O2 to degrade adsorbed contaminants by a catalytic Fenton-like reaction. In the pilot test, the Fe-zeolite (30 kg) maintained its performance over treatment of 1470 m3 of groundwater in 12 adsorption/regeneration cycles. High-silica iron-exchanged zeolite was applied for the first time in a pilot test for removal of chlorohydrocarbons from contaminated groundwater. The zeolite showed stable performance as adsorbent with intermittent on-site regeneration by flushing with hydrogen peroxide in 12 reuse cycles, treating about 50 000 bed volumes of groundwater. image
