The application discloses a stable and efficient inflatable mine flotation machine, which comprises a flotation column, a feeding mechanism, an inflation pump, a gas supplement mechanism, an aeration mechanism, a flow guide mechanism and a mixing mechanism. The feeding mechanism comprises a slurry pump and a mixing cylinder. The slurry pump is fixedly installed on the upper side of a mounting beam, and the mixing cylinder is fixedly installed on the middle part of the mounting beam. The slurry pump is in communication with the inside of the mixing cylinder and is used for realizing stable conveying and preliminary mixing of slurry. The gas supplement mechanism comprises a gas supplement pump, a gas distribution pipe and a gas distribution hole. A separate inflation pump primary gas supply structure and a gas supplement mechanism secondary gas supplement structure are arranged to form a multi-stage gas mixing system in cooperation with the internal mixing mechanism of the mixing cylinder. The inflation pump precisely supplies air through the inflation cover and the air inlet hole opposite the jet area of the slurry nozzle, and realizes primary negative pressure air mixing by using the high-speed jet negative pressure of the slurry. The gas supplement pump realizes circumferential uniform secondary air supplement in cooperation with the annular gas distribution pipe, the gas distribution hole and the gas guide cover, and avoids air floating and escaping.

This utility model belongs to the field of mineral flotation technology, and in particular relates to a mineralization device based on Bernoulli's principle, including a flotation column and a circulating sand pump, and a variable diameter mineralization pipe connecting the outlet of the flotation column and the circulating sand pump. The variable diameter mineralization pipe includes a premixing section fixedly connected to the outlet section of the circulating sand pump, a mineralization section fixedly connected to the end of the premixing section via a contraction cone section, and a buffer section fixedly connected to the end of the mineralization section via an expansion cone section. An annular air distributor is provided in the middle of the premixing section, including an annular cavity and circumferentially uniformly distributed micropores. An adjustable injection mechanism is provided at the outer end of the mineralization section, which automatically draws in reagents and injects them into the slurry using the negative pressure zone in the mineralization section. The buffer section is equipped with a dual-point reflux system, and the external circulation reflux pipe connects the buffer section and the contraction cone section. This device effectively avoids clogging problems and improves the contact efficiency between bubbles and minerals by combining the pressure gradient generated by Bernoulli's principle with circulation enhancement, thereby improving the mineralization effect.

The present application relates to the oilfield wastewater treatment and resource recycling technical field, disclose a kind of oilfield wastewater collaborative oxidation treatment method, comprising the following steps: the oilfield wastewater to be treated is introduced into flocculation reaction tank, and polyaluminium chloride is added to the oilfield wastewater to be treated, and after wastewater pH is adjusted, stirring is carried out, so that suspended oil, emulsified oil, colloidal particles and polyaluminium chloride hydrolysis product in wastewater collide, destabilize, coagulate, and form floc.The present application is coupled by micro-nano bubble enhanced air floatation and electroflocculation-ozone-hydrogen peroxide depth, so that the oilfield wastewater to be treated is sequentially subjected to flocculation, air-type micro-nano bubble air floatation, electroflocculation-ozone-hydrogen peroxide collaborative deep oxidation and standing precipitation treatment, which can eliminate the need for separate oxidation unit, simplify the process flow and improve the integration of the treatment process.
