| titleOfInvention | Arsenic-containing waste acid wastewater treatment method and treatment system thereof |
| abstract | The invention relates to a method and a system for treating arsenic-containing waste acid wastewater, wherein the method comprises the following steps: the method comprises the steps of sequentially carrying out neutralization treatment and primary sedimentation treatment on arsenic-containing waste acid wastewater, sequentially carrying out primary aeration treatment and primary filtration treatment on clear liquid obtained by the primary sedimentation treatment, sequentially carrying out secondary aeration treatment, secondary filtration treatment, ammonium fluoride calcium removal treatment and tertiary filtration treatment on the clear liquid obtained by the primary filtration treatment after electrochemical advanced treatment, storing the clear liquid obtained by the treatment for later use, and carrying out filter pressing treatment on underflow concentrate obtained by the primary sedimentation treatment, the primary filtration treatment, the secondary filtration treatment and the tertiary filtration treatment to obtain dry slag for outward transportation. In the treatment method provided by the invention, the arsenic-containing waste acid wastewater is treated by adopting the ordered combination of a ferrite aeration method, an electrochemical deep treatment method and an ammonium fluoride decalcification method, and all indexes of the treated effluent can reach the national discharge standard and can be completely recycled, thereby realizing zero discharge of the wastewater. |
