The invention discloses an alkaliphilic microorganism colony for degrading PVA in dyeing waste water, and relates to a microorganism colony. The invention aims to provide an alkaliphilic microorganism colony for degrading PVA in dyeing waste water with good degradation effect and low treatment cost. The technical scheme comprises that: the alkaliphilic microorganism colony for degrading PVA in dyeing waste water takes PVA, dyes and various auxiliary agents in the waste water as the only carbon source, and is prepared by the following step of: collecting waste water or sludge discharged from a dyeing plant and pouring the waste water or the sludge to the dyeing waste water, adding inorganic salt in the waste water in a proportion of 0.1 to 1 gram organic salt per liter of waste water, and culturing by the conventional microorganism culturing method. The invention is used for treating dyeing waste water.
