Kitchen waste wastewater, commonly known as greasy water, is garbage generated by residents during domestic consumption and represents a significant source of urban environmental pollution. It contains large amounts of organic matter, such as food residues, fats, proteins, and carbohydrates; high levels of suspended solids, including food particles and fat globules; and trace amounts of detergents and other chemicals. It also contains nutrient elements such as nitrogen and phosphorus, which may contribute to eutrophication of water bodies.
