Cellulose microsphere sewage filter and filtration method

Abstract

The invention relates to a sewage filter and a filtration method, and belongs to the technical field of environmental protection. The invention particularly relates to a cellulose microsphere sewage filter and a filtration method. The cellulose microsphere sewage filter comprises a cavity through which sewage flows; cellulose microspheres are arranged in the cavity; the cellulose microspheres are elastic, acid-proof and alkali-proof microspheres; the diameter of the cellulose microspheres is 2mm to 10mm, the specific surface area of the cellulose microspheres is 80 to 200m<2> / g, and the moisture content of the cellulose microspheres is 80% to 99%. According to the invention, the cellulose microspheres are used as a core of a filter element, the porosity is high, the specific surface area is large, the cellulose microspheres are acid-proof and alkali-proof, the use temperature range is wide, and no obvious deformation is generated during use; meanwhile, the cellulose microspheres can also be used as a good carrier of various adsorbents, and the filtration precision is high.

Description

technical field [0001] The invention relates to a sewage filter and a filtering method, belonging to the technical field of environmental protection, in particular to a cellulose microsphere sewage filter and a filtering method. Background technique [0002] Existing ordinary mechanical filters are heavy and inconvenient to disassemble. Moreover, because most of the mechanical filters use traditional filter materials such as quartz sand, anthracite, and pebble layers, there is a common problem of low filtration accuracy, which basically cannot meet the filtration requirements below the micron level. For example, the main structure of a mechanical filter involved in the authorized embodiment patent CN203736915U is very similar to the traditional mechanical filter, and the filter material used is also traditional quartz sand, anthracite, pebble layer and manganese ore; another example is the authorized embodiment patent The main structure design of a mechanical filter involve...
