Abstract

The invention relates to a PTA (Purified Terephthalic Acid) mother liquor wastewater deep treatment and cobalt-manganese recovery system. The PTA mother liquor wastewater deep treatment and cobalt-manganese recovery system comprises a mother liquor filter, a first-stage filtration and feeding tank, an iron removal filter, a second-stage filtration and feeding tank and a cobalt-manganese filter which are sequentially connected, wherein an lye tank is arranged between the first-stage filtration and feeding tank and the second-stage filtration and feeding tank. According to the PTA mother liquor wastewater deep treatment and cobalt-manganese recovery system, a staged treatment is adopted, good solid removal effect, the cobalt removal effect and the manganese removal effect are achieved, the resources are reasonably utilized and the sewage from the final stage is in line with discharge standards.

Example Embodiment

[0011] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0012] like figure 1 As shown, a kind of PTA mother liquor wastewater advanced treatment and cobalt manganese recovery system according to the present invention, it comprises mother liquor filter, one-stage regulating tank, iron removal filter, two-stage regulating tank and cobalt-manganese filter, which are connected in sequence , a lye tank is arranged between the first-stage regulating tank and the second-stage regulating tank; a PTA mother liquor waste water storage tank is arranged at the front end of the mother liquor filter; a sewage treatment station is arranged at the rear end of the cobalt-manganese filter; A filter iron recovery device is arranged under the iron removal filter; a cobalt and manganese recovery device is arranged under the cobalt-manganese filter. The method adopts segmental treatment, and has good effects of removing solids, cobalt and manganese. Through the system, PA and PT acid can be recovered, a large amount of cobalt and manganese ions can be removed, the load of subsequent sewage treatment can be reduced, and the cost can be well saved. This system meets the actual use requirements.
