Abstract
The invention belongs to the technical field of papermaking off-machine water and particularly relates to a processing method of paper machine wet end off-machine water. The processing method includes the steps of a, determining quantity of negative charge in the paper machine wet end off-machine water; b, adding cationic auxiliary according to the quantity of the negative charge. By measuring surface charge of the paper machine wet end off-machine water to detect chemical change of a wet end, addition of chemicals at the wet end is guided effectively and timely, running performance of a paper machine is improved, and service efficiency of the wet end chemicals is improved. The cationic auxiliary is added for neutralization after anions of the wet end off-machine water are measured, and accordingly papermaking rate is increased.
