By the intermittent test, we studied the acid fermentation rule after mixing excess sludge and distiller's grains. The results showed that the control sample and by the proportion of 0.2g/gTS, 0.4g/gTS, 0.6g/gTS added distiller's grains to the 4 reactors, the maximums of SCOD reached 775.83mg/L, 1136.92 mg/L, 1427.77mg/L and 2609.48mg/L, the TS loss ratios were 12.00%, 15.69%, 16.92% and 19.25%. With the increasing amount of distiller's grains added in, improving the performance of sludge dewatering centrifuge. At the same time, the activity of micro-organisms in the sludge is even greater. By means of molecular biology active sludge of microbial extract DNA, then PCR amplification, DGGE separation of PCR products, obtained fingerprints of microbial sludge. The results from the perspective of molecular biology to further confirm the above view. The acid fermentation after mixing sludge with distiller's grains can achieve on both resource use and the purpose of sludge reduction.
