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.

“…Generally, a biological technique is firstly applied to removing ammonia, COD and BOD, followed by an additional physicochemical treatment to remove non-biodegradable organic components [15][16][17][18][19] . Recently, to MBRs more attention is paid in landfill leachates treatment owing to their efficiency and small foot-print [15,16,[19][20][21][22][23][24] . The performance of some MBRs for treating landfill leachate is listed in Table 1.…”

“…It can be observed that the experimental data of the suspended E. coli cells represent a typical growth and decay curve with a well-defined growth phase, followed by a constant growth phase and the endogenous phase (Pirbazari et al 1996). The experimental data of Cr(VI) and suspended E. coli cells concentrations facilitate a priori estimation of biokinetic parameters by evaluating the growth rate of suspended E. coli cells and Cr(VI) reduction.…”

A mathematical model was developed to describe the reduction of Cr(VI) by Escherichia coli (E. coli) 33456 in a fixed biofilm reactor. A laboratoryscale column reactor was conducted to verify the model system. The batch kinetic tests were independently conducted to determine the biokinetic parameters used in the model simulation. With the assumed values of initial biofilm thickness (L f0 ), the mathematical model simulated well the experimental results for Cr(VI) effluent concentration, effluent concentration of suspended E. coli cells, and Cr(III) production. The concentration of suspended E. coli cells reached up to 1.2 mg cell/L while the thickness of attached E. coli cells was estimated to be 32.6 lm at a steady-state condition. At the steady state, the removal efficiency of Cr(VI) was about 92 % and the effluent concentration of Cr(III) was approximately 1.6 mg/L. The approaches presented in this study can be employed for the design of a pilot-scale or full-scale fixed biofilm reactor to treat Cr(VI)-containing wastewater.
