Blasticidin-S waste was treated by thermophilic and mesophilic methane fermentation.The characters of the waste are shown in Table 1.Digestion studies were conducted at temperature of 53〜54℃ (thermophilic) and 37〜38℃(mesophilic), and the concentration of the digested sludge in the fluid was ajusted to the range of 5〜30 vol.% (1,500G-10 min. centrifuged).The results of treatment at the various sludge concentration are shown in Table 3 and 5.The greater the quantity of the digested sludge contained in the fluid, the greater the gas production and the maximum loadings were obtained. The relationship between the concentration of the sludge and the maximum amount of loading is illustrated in Figure 1.The maximum loading was 0.95/l/day as volatile matter in 5 vol.% of the sludge, also 1.43 g in 10 vol.%, 5.24 g in 20 vol.% and 7.14 g in 30 vol.% under the mesophilic fermentation respectively. During thermophilic fermentation the maximum loadings were 3.81g in 5 vol.%, 4.76g in 10 vol.% and 8.57g in 20 vol.%. 80〜90% of B.O.D. was removed with C.O.D. and11 times as much ofthe gas (V/V) of the added slop was produced.
