Abstract: An integrated boron removal and flocculation process for treating fracturing wastewater is disclosed. The process comprises: adjusting the pH of the fracturing flowback liquid to be treated to become alkaline and adding thereto an oxidant to carry out a reaction for a certain time period, so that the state of the boron present in the liquid is changed; and then adding a barium salt to the resulting reaction mixture to carry out a further reaction between the barium salt and the boron in the changed state to produce a precipitate. The stability of the flowback liquid is deteriorated by the addition of the oxidant. Suspended solids in the flowback liquid can be removed through adsorption, wrapping, and then settling by the action of the precipitate (a barium salt). The process integrates boron removal and flocculation and enables a boron removal rate of 80% or greater. An integrated boron removal and flocculation process for treating fracturing wastewater is disclosed.
