摘要： A method of treating a waste water containing anionic surfactant and heavy metals, which comprises the steps of: adding a specific inorganic coagulant and a specific salt to said waste water so as to make the respective concentration of said inorganic coagulant and inorganic salt in the waste water be at prescribed levels, adjusting the pH value to be in the range of from 5 to 10 after adding said inorganic coagulant, further adding a cationic coagulant so as to make its concentration be at a prescribed level, and treating the thus processed waste water through the foam separating process.
