[0030] The flow guide pump 6 can be pressurized and guided, the filtration pressure strength of the coarse filtration tank 2 and the fine filtration tank 3 can be measured in real time by the pressure measuring table 7, and the oil-water separation tank 4 is provided with an oil outlet pipe 11 at the top, the oil-water separator can remove most of the working liquid components in the wastewater, can reduce the load of the subsequent membrane separation device, can ensure the stable operation of the membrane separation device, can prolong the service life of the membrane, the oil outlet pipe 11 can collect and return the working liquid, can play a recycling role, can make the device small and convenient, can occupy small area, and has good working liquid recycling capacity, is convenient to use, and has excellent filtration quality.

[0031] Membrane is a material with selective separation function. The process of separating, purifying and concentrating different components of feed liquid by using the selective separation of membrane is called membrane separation. It is different from traditional filtration in that membrane can separate in the range of molecules, and the process is a physical process without phase change and addition of additives. The basic principle of membrane separation process is relatively simple. In the filtration process, the feed liquid is pressurized by a high-pressure pump, and the feed liquid flows along the surface of the filter membrane at a certain flow rate. The molecules larger than the molecular weight of the membrane cut-off do not penetrate the membrane and flow back to the feed tank. The substances or molecules smaller than the molecular weight of the membrane cut-off penetrate the membrane to form the dialysate. Therefore, the membrane system has two outlets, one is the return liquid concentrate outlet, and the other is the dialysate outlet. The amount of dialysate flowing out per unit time (Hr) per unit membrane area (m2) is called membrane flux (LMH), that is, the filtration speed. The factors affecting the membrane flux include temperature, pressure, total dissolved solids (TDS), ion concentration, viscosity, etc. Since the membrane separation process is a pure physical process, it has the characteristics of no phase change, energy saving, small volume, and can be separated, so the membrane is widely used in fermentation, pharmaceutical, plant extraction, chemical industry, water treatment process and environmental protection industry. For different compositions of organic matter, different membranes are selected according to the molecular weight of the organic matter, and appropriate membrane process is selected, so as to achieve the best membrane flux and retention rate, thereby improving the production yield, reducing the investment scale and operation cost.
