Embodiment 1
[0115] The composition of a gold concentrate cyanidation leaching residue leaching waste liquid is shown in Table 3
[0116] Table 3 Composition of a gold concentrate cyanidation leaching residue leaching waste liquid
[0117] Unit: mg / L, pH dimensionless
[0118]
[0119] From the composition of the above wastewater quality, it can be seen that the main pollutants of wastewater are CN T 、SCN - , As, COD, where SCN - The proportion of COD is relatively high, so the reaction process is mainly for the analysis and determination of the above four pollutants. see figure 1 and figure 2 Shown:
[0120] (1) Pretreatment section: After the waste liquid to be treated passes through the grit chamber to settle the solid suspended matter in the waste liquid, it enters the equalization tank.
[0121](2) Continuous treatment: Turn on the upper liquid pump to extract the liquid to be treated from the equalizing tank at the maximum flow rate, and pour it into the oxidation reactor ...
