The invention discloses a nickel-containing electroplating wastewater treatment device comprising a wastewater pretreatment system, a first storage tank, a low-temperature vacuum concentration system,a security filter, a second storage tank, a nanofiltration device and an MBR device, and a method comprises the following steps: S1, filtering; S2, precipitating; S3, separating by virtue of the low-temperature vacuum concentration system; S4, temporarily storing; S5, nanofiltering; and S6, carrying out microbial decomposition. The system is simple to construct, the treatment device is basicallydivided into seven modules, after nickel-containing electroplating wastewater is sequentially treated by the seven modules, the water quality meets the discharge standard; the system is compact and reasonable in facility layout and small in occupied area, all process modules are optimized, the optimal operation condition is found, and the treatment efficiency and operation energy consumption are greatly improved; compared with a traditional treatment method, sludge is not generated, nickel ions basically exist in waste liquid discharged by the low-temperature vacuum concentration device completely, and recycling treatment can be conducted.
