摘　　要： 研究预处理方法对麦草P-RCAPMP废水以及磨浆和成浆性能的影响,探讨不同的预处理方法对废水的有机负荷、磨浆能耗、纸浆物理性能及纤维形态的影响。结果表明,热水浸泡和挤压疏解预处理能显著降低废水中COD含量,节省磨浆能耗,提高纸浆质量。在TM/P(热水浸泡后,经挤压疏解机挤压后再化学预处理)的预处理条件下,COD含量下降13.5%,磨浆能耗降低10.2%,撕裂指数提高15%,裂断长提高6.6%,白度增加6.3%ISO。 Effects of seveal pretreatments of P-RC APMP wheat straw pulp on the organic loading of wastewater,refining performance,pulp physical properties,and fiber morphology were studied.e results showed that hot water soaking and squeezing extrusion could reduce the content of COD in the wastewater,save refining energy consumption and promote pulp quality.Under the pretreatment condition of TM/P（T：hot water soaking,M：squeezing extrusion,P：chemical pretreatment）,the content of COD,refining energy consumption was decreased by 13.5%,10.2%respectively and the tear index,breaking length brightness was increased by 14.7%,7%,6.3% ISO respectively.
