| description | The invention provides a zero discharge process and equipment for a silicon steel reverse osmosis concentrated solution, a filter material, an adsorbent and a preparation method. The water quality of the concentrated solution is as follows: soluble COD (Chemical Oxygen Demand) is 22-31 mg/L, the turbidity is 34-53 NTU, calcium ions are 17-29 mg/L, silicon ions are 4-14 mg/L, and the conductivity is 81600-113890 [mu] S/cm; comprising the following steps: 1, a concentrated solution to be treated firstly enters a modified filter tower, and a modified iron slag-activated carbon filter material is placed in the modified filter tower; after the concentrated solution passes through the modified filtering tower, the solubility COD of the concentrated solution is 4-6 mg/L, the turbidity is 3-7 NTU, calcium ions are 13-26 mg/L, and silicon ions are 2-7 mg/L; 2, the concentrated solution enters a resin adsorption tower through a lifting pump, a modified chelating resin adsorbent is placed in the resin adsorption tower, |
