Description

Technical Field

[0001] The utility model relates to the technical field of solid-liquid separation, in particular to a waste solid-liquid separation device used in environmental protection engineering. Background Art

[0002] Solid-liquid separation technology in environmental protection engineering is a technology used to separate solid waste from liquid. This technology is usually used in environmental protection fields such as wastewater treatment, sludge treatment, and solid waste treatment. The application of solid-liquid separation technology can reduce the content of solid particles in sewage discharge, thereby achieving the purpose of purifying water quality and reducing environmental pollution. Solid-liquid separation technology usually includes two methods: physical and chemical methods. Physical methods include filtration, sedimentation, centrifugation, filter press, cyclone separation and other technologies. Filtration is the most basic solid-liquid separation method. Solid particles are intercepted and clean liquids are separated by filtering media (such as filter cloth, filter screen, filter paper, etc.). Centrifugation is a separation effect based on centrifugal force, which is often used in situations where the particle size difference in solid-liquid mixtures is large. Filter press is a separation method that forces water to pass through the filter medium by applying pressure to remove solids. Cyclone separation separates solids and liquids through the cyclone action in the cyclone. Chemical methods commonly used include flocculation sedimentation, flotation and other technologies. Flocculation sedimentation is to add flocculants to condense suspended solid particles into larger particle groups, and then achieve solid-liquid separation through gravity sedimentation. Flotation technology injects gas into water to generate tiny bubbles, which make solid or oil particles float to the surface of the water and then remove the residue to achieve solid-liquid separation. In environmental protection projects, the application of solid-liquid separation technology can effectively treat sewage, solid waste, etc., reduce the impact on the environment, and achieve the purpose of purifying water quality and recycling resources.

[0003] However, the physical separation and filtration methods used in the solid-liquid separation technology in previous environmental protection projects are not thorough enough, and it is difficult to carry out the next step of filtration and purification. Secondly, the efficiency of the solid-liquid separation equipment in traditional environmental protection projects is relatively slow. Utility Model Content
