摘要：The present invention belongs to the technical field of wastewater treatment, and particularly relates to a method for pre-conditioning high-calcium wastewater by calcification blocking, and a device for implementing the method. As provided by the present invention, the method for treating high-calcium wastewater by calcification blocking includes the following steps: mixing high-calcium wastewater, an alkalizing agent and a chelating agent, and carrying out alkalizing conditioning pretreatment under a condition of stirring by bubbling of a biogas, so as to obtain pre-conditioned wastewater; mixing the pre-conditioned wastewater with anaerobic granular sludge, and performing an anaerobic reaction in a high hydraulic shear flow field formed by the biogas, so as to generate the biogas and calcium scale; refluxing a part of the biogas for the stirring by bubbling of the biogas, and refluxing the rest of the biogas for forming the high hydraulic shear flow field.
