[0021] The technical solution of the present invention will be further described with reference to the drawings and embodiments.
[0022] by figure 1 It can be seen that the oilfield produced water composite treatment system is connected by an oil-water separator 1, a buffer water tank 2, an inorganic carbon membrane processor 3, a water storage tank 4, a filter adsorption processor 5, a backwash pump 7 and a purified water tank 6 through pipelines. constitute.
[0023] Among them: the oil-water separator 1 belongs to the pretreatment unit, which can be a cyclone, a swash plate degreasing device, or a three-phase separator, which is a common equipment. The water inlet of the oil-water separator 1 is the same as the oil field produced water. The water outlet of the oil-water separator 1 is connected with the water inlet of the buffer water tank 2 through the pipe, and the water outlet of the buffer water tank 2 is connected with the water inlet of the inorganic carbon membrane proce...
