| 摘 要： | 应用化学絮凝法和氧化法相结合的方法对造纸黑液进行了研究．采用不同的絮凝剂分别对造纸黑液进行处理，筛选出了絮凝剂的种类并确定了最佳用量．然后将其配制为复舍絮凝剂，对造纸黑液进行处理，使COD指标由原来的11000mg／L降至1750mg／L；再经选用的氧化剂进行氧化处理，可使COD值降至166mg／L．经过处理的废水，可作为造纸制浆的二次用水，使造纸废水达到循环利用，实现零排放。

| Abstract: | The wastewater of papermaking was regarded as researching object. The wastewater was disposed by several flocculants, and COD value was lowered from 11 000 mg/L to 1750 mg/L. Then method of oxidization was used, COD value was lowered 166 mg/L. The wastewater was disposed and used as water of paper pulp. Wastewater of papermaking was used circularly and was not exhausted. |
