A method of treating waste liquors containing phenol.

摘要

Conventional methods of treating waste liquors containing phenol suffer from a variety of disadvantages. For example in the activated sludge method large amounts of water are needed and a large volume of diluted waste liquor has to be treated. Such problems can be overcome by using a strain of the fungus Aureobasidium pullulans which is capable of assimilating phenol in the presence of methanol and formaldehyde and which is carried on a support. The waste liquor contacts the supported fungus, and the phenol is assimilated by the fungus, which grows. This technique can be used to treat waste liquors emanating from a phenol resin production plant.
