文章应用强化混凝技术对湘江原水中天然有机物的去除效果进行了研究。通过选择混凝剂、增加混凝剂的用量和降低pH值等措施强化混凝处理湘江水。实验结果表明，选用聚合氯化铝（PAC）作为混凝剂，并控制PAC的投加量为3×10～mol·L^-1，pH在5～6之间，能有效去除湘江水中的有机物。同时还初步探讨了TOC和UV-254之间的相关性，得出UV～254=0．0485×TOC-0．0738。

The water of Xiangjiang River was treated by enhanced coagulation. The selection of the suitable coagulant, the suitable coagulant dosage and the suitable pH was studied. Results show that organic matters can be removed effectively with the dosage of polyaluminum chloride（PAC） of 3 × 10^-4 tool·L^-1 and with the pH between 5 and 6. The pertinence of TOC and UV - 254 was also discussed and concluded UV - 254=0. 048 5 × TOC - 0. 073 8.
