[0067] In order to deepen the understanding of the present invention, the present invention will be described in further detail below in conjunction with the embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.
[0068] See figure 1 The shown schematic diagram of the system structure for recovering salt from the wastewater treatment system reveals that the specific process of the present invention is as follows:
[0069] (1) Waste water enters from the wastewater (1) flows into the system, and strengthens the oxidizer (2) to oxidize the reducing substances in the wastewater;
[0070] (2) The wastewater passes through the COD removal unit (3) to remove oxidized organic pollutants, nitrite, sulfide, ferrous salts, and residual membrane scale inhibitors and NH 4 -N, etc., the COD removal unit adopts adsorption material to remove COD, the adsorption material is one or...
