| description | The invention belongs to the technical field of diatomite recycling, and particularly provides a method for recycling waste diatomite after filtration of fracturing flow-back fluid, which comprises the following steps: uniformly mixing waste diatomite with clear water, adding a cleaning and repairing agent into the uniformly mixed mixture, and uniformly stirring to obtain a mixture; stirring the mixture added with the cleaning and repairing agent until the mixture is completely reacted, carrying out solid-liquid separation on the completely reacted mixture, directly filtering the separated solid, or drying, screening and reusing the separated solid, and using the separated liquid for compounding the fracturing fluid; the invention solves the problems that the waste diatomite generated after the fracturing flow-back fluid is filtered has no treatment scheme at present, can only be classified into oily sludge for outsourcing treatment, is high in cost, cannot be reused and causes waste, and has the advantages o |
