The invention discloses a filter element for paper industry sewage treatment. The filter element comprises a filter element main body, wherein the filter element main body comprises an outer filter layer, a middle filter layer and an inner filter layer; the outer filter layer is a filter screen, the middle filter layer is a filter plate, and the inner filter layer is adsorption filler. The filterelement is simple in structure and reasonable in design, by means of multi-level filtration and adsorption, large and small particle pollutants in paper industry sewage can be effectively removed by filtering, the quantity and types of the pollutants are greatly reduced with a physical method firstly, the pollutants are then treated with a sewage treatment agent, so that use of sewage treatment agent is reduced substantially, and the treatment cost is saved. 本发明公开的种用于纸业污水处理的滤芯，包括滤芯主体，滤芯主体包括外过滤层、中过滤层和内过滤层，外过滤层为滤网，中过滤层为过滤板，内过滤层为吸附填料，本发明结构简单，设计合理，设置多层级过滤吸附，可有效滤除造纸污水中的大颗粒和小颗粒污染物，通过物理法先大幅降低污染物数量和种类，在使用污水处理剂进行处理，大幅度降低了污水处理剂
