摘要：

Laboratory-scale experiments were conducted to determine new technology of waste sludge facultative metabolism. 10-L laboratory-scale facultative reactors were operated during 24-hour sludge residence time at room temperature. The results show that the organic matter in waste sludge after hydrolysis-acidification is reduced by 75.39%, and the removal rate of CODcr is above 85%. Hydrolysis-acidification can be realized at ambient air temperature as there is no need for facilities to be sealed or heated. The sludge is recycled into the wastewater treatment system and finally towards zero-discharge.
