Embodiment
[0031] Attached below figure 1 The two-dimensional structure diagram describes the filter of this embodiment in detail. The equipment is mainly composed of water inlet 1, variable diameter 2, DN250 flange 3, permeable cap 4, blind flange 5, flushing inlet flange 6, filler port flange 7, water distribution plate 8, screen pipe 9, flushing pipe 10. Cylinder body 11, fiber ball filler 12 and other parts. The filter element is realized in the following way: according to the characteristics of the treated sewage and the adsorption characteristics of various microspheres, adjust the mass percentage of various cellulose microspheres in the filter element, and directly fill it in this implementation after mixing. In the filter designed as an example, it is used in the field of water treatment with deep filtration requirements.
[0032] Before the filter works, at first the water inlet and outlet valves need to be closed, and then the fiber ball filler 12 is added to the feed bin fro...

Abstract
The invention relates to a preparation method of a cellulose microsphere, and a sewage treatment method, belongs to the technical field of environmental protection, and particularly relates to a preparation method of the cellulose microsphere for advanced water treatment, and the sewage treatment method. According to the preparation method and the sewage treatment method, the cellulose microsphere adopting a structure comprising abundant micro-nano holes serves as a filter element, so that the microsphere used by the filter element is high in porosity, large in specific surface area, wide in service temperature range, high in filter accuracy and acid-alkali resistant, has no significant deformation in a using process, and can serve as a good carrier of various adsorbents.
Description
technical field [0001] The invention relates to a method for preparing cellulose microspheres and treating sewage, belonging to the technical field of environmental protection, and in particular to a method for preparing cellulose microspheres for advanced water treatment and treating sewage. 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...
