Description

Technical Field

[0001] The utility model relates to the technical field of filter press devices, in particular to a filter press device for harmless feces treatment. Background Art

[0002] Urban feces treatment is a global problem. If it is not properly solved, it will seriously affect the space and quality of human life. If the organic matter and nitrogen, phosphorus and other substances in feces are directly discharged, it will cause water pollution and emit harmful gases containing ammonia, hydrogen sulfide, mercaptan, sulfide and other foul-smelling components. Among them, the feces of patients contain a variety of intestinal bacteria, parasite eggs and viruses. 70% of diseases in developing countries are related to biological transmission of feces. Therefore, it is of great practical significance to reduce the amount of feces, make them harmless and recycle them. Feces harmlessness refers to the way of collecting, storing and treating feces in accordance with relevant national regulations.

[0003] Most of the existing filter press devices for harmless treatment of feces directly use feces filter presses for solid-liquid separation, which cannot separate paper, plastic bags and other debris in the feces mixture. Although the feces are separated from liquids such as urine, the debris still remains in the solidified feces, which is easy to cause blockage in the filter press process and affect the subsequent treatment of the solidified feces.
