Abstract
PURPOSE: To provide a method of the treatment of waste water, wherein the waste water resulting from pyrolysis treatment of waste is subjected to coagultation treatment to separate off heavy metals and reducing substances, and then the waste water is subjected to oxidative destruction by the alkali-chlorine method to decompose cyanides in the water, so that the purification of the waste water is effectively carried out.
CONSTITUTION: The addition 3 of NaOH to a waste water 1 resulting from pyrolysis treatment of waste is carried out in a tank 2 to adjust the pH value of the waste water 1 to about 10, the waste water 1 is transferred to a coagulation tank 4 where a high-molecular weight coagulant 5 and an inorganic coagulant 6 are added to coagulate and remove heavy metals and reducing subsances, the thus treated water is transferred to an oxidation column 7 where the pH value of the water is adjusted by NaOH to between 10 and 12 followed by the addition 8 of NaOCl to effect primary oxidation of cyanide components and where then the pH value of the water is adjusted to between 8 and 9 by the addition 9 of H2SO4 followed by the addition 8 of NaOCl to effect secondary oxidation of the cyanide components. After these oxidation treatments, a high-molecular weight coagulant 12 is added to the thus treated water in a tank 11,the addition 14 of H2SO4 is carried out in a tank 13 to neutralize the water, and the water is transferred through a reservoir 15 to a sand filter column 16, then to an active carbon adsorption column 17 where it is subjected to the respective treatments, and thereafter is discharged.
