Acrylic acid wastewater treatment device

The invention belongs to the technical field of wastewater treatment, and particularly relates to an acrylic acid wastewater treatment device. Comprising a cross-flow RO filtering device and an acrylic acid wastewater concentration device, and a liquid outlet of the cross-flow RO filtering device is communicated with a liquid inlet of the acrylic acid wastewater concentration device; when in use, the concentration of organic pollutants containing acrylic acid and acetic acid is increased by adopting the cross-flow RO filtering device, and then concentrated waste liquid is recycled through the acrylic acid wastewater concentration device. The method has the advantages of low energy consumption, high efficiency, no secondary pollution and the like, the recovery rate of acetic acid in the wastewater is high, commercial-grade acrylic acid, acetic acid and other products can be recovered from the acrylic acid wastewater, and wastewater recycling is realized. 本发明属于废水处理技术领域，具体涉及一种丙烯酸废水处理装置。包括错流RO过滤装置和丙烯酸废水浓缩装置，所述错流R
