Embodiment Construction
[0058] The present invention will be described in further detail below through specific implementation examples and in conjunction with the accompanying drawings.
[0059] a. Pretreatment: Collect the produced phenol cyanide wastewater in the phenol pool for pretreatment;
[0060] When 25-30 tons of phenol cyanide wastewater is produced per month, the phenol cyanide wastewater is collected by a phenol pool with a length of 3m, a width of 1.5m, and a height of 2.5m for pretreatment
[0061] b. Granulation water replenishment: when the material is granulated, according to the original water content ratio of the material, the phenol cyanide wastewater is used to replenish the water of the material;
[0062] c. Melting: The phenol cyanide wastewater is attached to the material particles, enters the Isa furnace from bottom to top with the feeding system, passes through the high temperature of the melting pool greater than or equal to 1200 degrees Celsius, and the phenol cyanide was...
