| Abstract: | Landfill leachate, whose main pollutants are organic matter, heavy metals and ammoniacal nitrogen, is a kind of poisonous, harmful and organic wastewater. The pretreatment of landfill leachate by flocculation-adsor-ption was investigated. Polyaluminium chloride (PAC) was used as the flocculant and its optimum dosage was 500 mg/L. The adsorbent was self-made modified bentonite. Experimental results showed that approximately 79% of CODCr and 46% of ammoniacal nitrogen were removed. As to heavy metals, the removal ratios were from 53% to 98% according to different kinds of landfill leachate. |
| Keywords: | leachate pretreatment polyaluminium chloride modified bentonite |
