Description: The invention provides a papermaking technology, and relates to the technical field of industrial papermaking. The papermaking technology comprises the steps of pulp cooking, pulp washing and bleaching and paper machine papermaking, wherein electrochemical water treatment is respectively carried out on black liquor generated during the pulp cooking, middle-stage water generated after the pulp washing and bleaching and off-machine water generated during paper machine papermaking to form micro-cluster water, raw water supplied to the steps of pulp cooking and pulp washing and bleaching is the micro-cluster water after the electrochemical water treatment, liquid supernatant of the black liquor is taken after the electrochemical water treatment is carried out on the black liquor, the liquid supernatant serves as the raw water to be used after biochemical treatment is carried out on the liquid supernatant, the middle-stage water and off-machine water after the electrochemical water treatment is circularly used for
