| description | In most countries,
sanitary landfill is nowadays the most common
way to eliminate municipal solid wastes (MSWs).
However, sanitary landfill generates large
quantity of heavily polluted leachate, which can
induce ecological risk and potential hazards
towards public health and ecosystems. The
application of advanced oxidation processes
(AOPs) including ozone-based oxidation, Fenton
oxidation, electrochemical oxidation, and other
AOPs to treatment of landfill leachate was
reviewed. The treatment efficiency in term of
chemical oxygen demand (COD) of various AOPs was
presented. Advantages and drawbacks of various
AOPs were discussed. Among the AOPs reviewed,
Fenton process should be the best choice, not
only because it can achieve about
49~89% of COD removal with COD ranging
from 837 to 8894 mg/L, but also because
the process is cost-effective and simple in
technological aspect, there is no mass transfer
limitation (homogeneous nature) and both iron
and hydrogen peroxide are
nontoxic. |
