This invention addresses the issue that while there is a corresponding relationship between the components and oil absorption value in the glassine paper coating process, this relationship is non-linear and cannot be easily predicted. Therefore, it provides a soft measurement model based on SA-PSO-LSSVM to predict the oil absorption value of glassine paper. This model enables accurate detection of the oil absorption value in the glassine paper coating process, providing a quick method for optimizing the glassine paper coating process. It uses real daily production data from paper mills and is applicable to the actual production activities of most paper mills.

This invention relates to the field of environmental engineering and waste resource utilization technology, and discloses a modified biochar preparation and application for enhancing methane production from anaerobic fermentation of recycled paper mill wastewater. The modified biochar uses recycled paper mill wastewater sludge biochar as a base, which is sequentially modified by loading nano-manganese iron spinel and encapsulating polyaniline conductive polymer. The material of this invention possesses high conductivity, paramagnetism, selective adsorption, and microbial carrier functions, synergistically promoting direct interspecies electron transfer, breaking down recalcitrant organic matter, adsorbing toxic substances, and buffering system pH, thereby significantly improving methane production, rate, and system stability during anaerobic fermentation of recycled paper mill wastewater. This invention achieves "waste-to-waste treatment," providing new materials and technologies for the efficient energy recovery of recycled paper mill wastewater.

The application discloses a paper mill production wastewater treatment device, and belongs to the wastewater composite treatment field, which comprises a treatment part; the treatment part comprises a cylindrical section, a liquid inlet tangentially arranged on the cylindrical section and communicated with an inner chamber of the cylindrical section, an overflow pipe fixed on the upper end of the cylindrical section and extending into the inner chamber of the cylindrical section, a conical section integrally formed with the lower end of the cylindrical section, and a discharge port arranged on the lower end of the conical section; the application further comprises a premixing part fixed on one side of the outer wall of the cylindrical section and communicated with the liquid inlet; when the paper mill wastewater enters the premixing part, the negative pressure generated by the high-speed fluid is used to suck the magnetic seeds and coagulants in the feeding port; the violent turbulence in the premixing part can make the magnetic seeds, coagulants, fine fibers and fillers in the wastewater fully contact in a very short time, form a "micro-flocculation body" with the magnetic seeds as the core, supplement the flocculants in the shear zone, and can "wrap" and "repair" the primary flocculation body, so that the breaking effect caused by the feeding impact is offset.
