Abstract

PURPOSE: To effectively dispose of waste water containimg emulsified oil and separate a surface active agent and an oily substnace from the waste water, by bringing the waste water containing emulsified oil into contact with a compound selected from a goup of oxides and hydroxides of alkaline earth metals, under a prescirbed condition.
CONSTITUTION: The emulsified-oil waste water containing the surface active agent and the oily substance is brought into contact with the compound selected from the group of oxides and hydroxides of alkaline earth metals such as magnesium, calcium, etc., at 10 or more in pH level and 30°C or more in temperature, preferably 10 to 13 in pH level and 30 to 60°C in temperature. At that time, the surface activating property of the surface active agent would fall because of the hydrolysis of the ester-type agent or the change of the anionic agent to insoluble salt. The fall in the surface activating property is prevented and a coagulant, preferably, iron salt or the like is added to the waste water in performing coagulation and sedimentation. As a result, the surface active agent and the oily substance are separated as sludge from the waste water.
