本文讨论的制浆工艺，即热机械制浆（TMP）和化学热机械制浆（CTMP），是一种高得率的工艺，通常根据单位木材产生的纤维量为90%或更多。在这些过程中，木质素溶解较少，因此纸浆产量较高。TMP工艺包括在机械精炼之前对木屑进行蒸汽处理，而CTMP工艺包括在蒸汽处理和机械精炼之前的化学浸渍步骤。工艺用水中木材产量的损失和包括木质素在内的木材溶质的增加与制浆（温度和化学负荷）和漂白条件的严重程度有关。与硫酸盐法相比，TMP和CTMP法每吨纸浆使用的水更少，废水更浓。 由于木质素等有机化合物不利于生物处理过程，进入地表水的生物处理废水具有高水平的溶解有机碳（DOC）和化学需氧量（COD）。这些有机化合物可能对化学氧化剂（如水氯）仍有相当大的反应性。本文报告的工作目标包括:确定饮用水处理条件对使用阿魏酸作为木质素模型化合物产生特定氯化副产物的影响；以及确定和量化这些目标氯化副产物，这些副产物来自于在天然水中稀释的TMP和CTMP工厂废水的氯化。

The pulping processes discussed in this paper, thermomechanical pulping (TMP) and chemithermomechanical pulping (CTMP), are high yield processes, typically 90% or more based on the amount of fiber produced per unit of wood. Less lignin is dissolved in these processes, and thus pulp yields are higher. The TMP process involves steaming the wood chips before mechanical refining, while the CTMP process includes a chemical impregnation step before steaming and mechanical refining. Losses in wood yield and increased wood solutes, which include lignin, in process water are related to the severity of pulping (temperature and chemical charge) and bleaching conditions. Less water is used in the TMP and CTMP processes per ton of pulp produced than in the kraft process and the effluents are more concentrated. Biologically treated effluents entering surface waters have high levels of dissolved organic carbon (DOC) and chemical oxygen demand (COD) due to organic compounds such as lignin which are recalcitrant to biological treatment processes. These organic compounds may still have considerable reactivity to chemical oxidants such as aqueous chlorine. The objectives for the work reported here include: determining the effect of drinking water treatment conditions on producing specific chlorination byproducts using ferulic acid as a lignin model compound; and identifying and quantifying these target chlorination byproducts resulting from the chlorination of TMP and CTMP mill effluents diluted in natural waters.
