Abstract

PURPOSE: To treat waste water containing certain polyalkylene type compound (PAG) efficiently with activated sludge, by keeping the waste water feeding rate within a certain particular range.
CONSTITUTION: In treating waste water containing PAG (for instance, polyethylene glycol) having an average molecular weight of 200W2000 with activated sludge, waste water feeding rate is controlled at a value lower than 200g-PAG/kg- MLVSS.day, in terms of PAG, whereby it is enabled to treat waste water with activated sludge with high efficiency. In the above treatment, it is also possible to use inorganic nutritive agent and oxygen source that are commonly available.
