Abstract:
The present invention relates to a method for increasing polyhydroxyalkanoates (PHAs) content of waste sludge, by taking the fermentation liquid fermented from waste sludge as a carbon source, and performing ADF domestication process, thereby quickly raising PHAs contentin the waste sludge, in accordance with the method of the present invention, the conventional complicated domestication steps is simplified and a higher content PHAs can be produced, additionally the added carbon source of the present invention is the VFA fermented by the waste sludge, so it's unnecessary to add extra material, therefore including more industrial utilization.

Claim (Index 1):
A method for increasing PHAs content of waste sludge, comprising steps of:\n diluting the waste sludge with water and performing oxygen aeration and activation to get an activated waste sludge; fermenting another waste sludge other than the activated and aerated waste sludge for 4\u02dc6 days at a temperature of 40\u00b0 C.\u02dc50\u00b0 C. to get a fermentation liquid; and injecting the fermentation liquid into the activated waste sludge to perform microorganism domestication and synthesize PHAs; wherein when the Dissolved Oxygen (DO) of the activated waste sludge reaches 75%\u02dc85%, injecting the fermentation liquid to the activated waste sludge to synthesize PHAs and reinjecting the fermentation liquid to the activated waste sludge when the DO of the activated waste sludge drops to 65%\u02dc75%, and repeating the steps for 5\u02dc10 times.
