[0021] Reference Figure 1 As shown, the existing methods for treating food waste mainly include physical methods, chemical methods, and biological methods. Among them, physical sorting treatment generally uses separation equipment for separation. The separation equipment separates the solid matter, oil, water and other components in the food waste, and then collects or discharges them in a unified manner to make full use of them and reduce pollution. In the existing separation equipment, after the solid-liquid separation of the kitchen waste, the oil-water mixture enters the separation chamber, and is layered due to the different densities of the oil and water. By setting drainage ports of different heights, different liquid layers enter different drainage ports for discharge. Most of the existing oil-water separators treat the solid waste in the oil and water by filtering it through a filter plate in advance to achieve the purpose of removing the solid waste. However, filtering through the filter plate will affect the efficiency of the solution to be filtered entering the separator, thereby greatly reducing the separation efficiency of the oil-water separator.
