This study aims to find a solution to the problem how to treat increasing food waste as time goes on. And this study develops the digesting method of mixing food waste and sewerage sludge as a part of treating food waste. sewerage sludge and food waste were digested in mesophilic condition with the mixing ratio of 1 to 0.1, 1 to 0.3, 1 to 0.5, 1 to 1 and 1 to 2 respectively for 40 days.
As the result, the digester(tank) with mixture packing of food waste showed stable in about 11days of digestion period, and in particular, in case of 1 to 0.1 as mixing proportion, removal of VS was the most enormous.
The highest chlorine ionic concentration in digestion showed 4700mg/l, which didn't have great effects on removal of VS.
