The invention relates to the technical field of environmental protection, and discloses a wastewater neutralization treatment device for environmental protection. According to the environment-friendly wastewater neutralization treatment device, through the rotating mechanism, after wastewater and neutralization liquid are mixed, the fusion stroke of the wastewater and the neutralization liquid is also converted into a spiral line advancing mode, the neutralization time of the wastewater and the neutralization liquid can be effectively prolonged, and due to the fact that the wastewater and the neutralization liquid are in a high-speed rotating state, the mixing efficiency can be effectively improved, and the mixing quality can be improved; by means of the driving motor, the function of conveying the waste water can be achieved, rotation driving of the waste water can be achieved, the high-speed centrifugal state is generated, meanwhile, rotation driving of neutralization liquid and the waste water in the opposite direction can be achieved, one machine has multiple purposes, and each function is progressive in relation. And therefore, the kinetic energy utilization rate is effectively improved.
