【Abstract】With simple process, convenient operation and lower costs, vermifiltration has been used in industrial practice and proved to be
effective in sludge reduction without affecting treated water quality. Further researches have to be conducted for decreasing the concentration of P
and N in treated water in vermifiltration process. Problems of uneven water distribution, impounded water and vermifiltration bed clogging by sludge
needed to be solved. Further researches on conversion of pollutants or sludge in the vermifiltration system needed to be conducted. To improve the
sludge reduction effecicency, it is necessary to optimize the conditions of hydraulic loading, pollutant loading and temperature during vermifiltration
process.
