摘要：
Hard organic compounds such as humic, fulvic in leachate which require treatment to make it dischargeable into the water stream. CWs is designed in the dimension of DxRxH = 2.5x0.8x0.5m. The filter materials used are small pebbles, crushed stone, and large pebbles. In this work, the effectiveness of removing colour and COD from leachate with Canna Lily CWs with activated sludge. Removal of COD and colour by CWs were 75.2% and 80.0% after 5 days, COD removal and colour increase were 9.7%, 5.6%, when adding 200mg of activated sludge to CWs. The quality of leachate is up to standard with HTR of 6 days with COD and 7 days with colour. The treatment time for leachate meets QCVN 40:2011/BTNMT standards is 7 days.
