Problems solved by technology
[0004] The purpose of the present invention is to provide a kitchen waste oil-water separation membrane treatment method for reducing the oil content of waste water, so as to solve the problem of using a centrifuge to separate oil and water from residual waste in the above-mentioned background technology, but in the process of centrifugal separation, it is difficult to separate The residue is discharged from the inside of the centrifuge, and the accumulated residue after repeated use will directly affect the oil-water separation effect, and the replacement of the internal purification membrane is troublesome, and the inner wall is difficult to clean, which will increase the maintenance cost of the membrane treatment and reduce the overall practicability The problem

The invention discloses a kitchen garbage oil-water separation membrane treatment method for reducing the oil content of wastewater. A separation tank is included and is a main outer frame structure of equipment, a blow-off pipe is arranged at the left lower end of the separation tank, a second one-way valve is mounted in the blow-off pipe, and a through hole is formed in the top surface of the separation tank; a pressure sensor is included and located on the outer surface of one end of the separation tank, and the outer surface of the pressure sensor is connected with a pressure release valve; and a sleeve is included and located at the top end of the separation tank, a booster pump is arranged at the top end of the sleeve, and the output end of the booster pump is connected with a circulating water pipe. According to the kitchen waste oil-water separation membrane treatment method for reducing the oil content of the wastewater, the pressure generated by downward lifting of a piston rod is matched, the separation speed of oil and water in the hollow fiber membrane can be increased, secondary pollution of purified water can be avoided, oil stains and garbage are isolated on the outer wall of the hollow fiber membrane, and the problem that the separated kitchen garbage is difficult to treat is solved.
Description
technical field [0001] The invention relates to the technical field of kitchen waste, in particular to a method for treating kitchen waste with an oil-water separation membrane for reducing the oil content of waste water. Background technique [0002] With the promotion and enforcement of domestic waste classification in my country, the demand for collection and treatment of kitchen waste (including kitchen waste, household kitchen waste and other kitchen waste) in urban domestic waste is increasing day by day, and many cities have established kitchen waste. In the treatment plant, in order to meet the requirements of the anaerobic fermentation process at the back end of the treatment plant, it is generally necessary to separate the oil and water of the kitchen slurry during the pretreatment of the kitchen waste. After separation, the oil content in the slurry is controlled below 1%. The moisture content of the phase is controlled below 2.0%. At present, the oil-water separati...
