研究了澄清剂处理、沉降和冷冻等方法对黄水的澄清作用。通过单因素试验发现：每种方法对黄水都有一定的澄清效果；不同澄清剂处理的最佳添加量分别为：皂土澄清剂0.06%，壳聚糖澄清剂0.08%，皂土与壳聚糖混合（配比4∶3）澄清剂0.14%；自然沉降处理的最佳时间为48 h；冷冻处理的最佳时间为24 h。在最佳澄清条件的基础上，通过感官分析、吸光值和透光率判断最佳澄清处理效果，根据理化指标分析黄水风味成分损失情况，综合对比，最终确定最佳澄清方法为壳聚糖澄清法，处理后的黄水澄清透亮。

In this paper, the clarification of yellow water by use of clarifying agents, settlement method, or freezing method etc. were investi-gated. Single factor test proved that each clarifying method had certain clarifying effects on yellow water. The best adding levels of different clarifying agents were summed as follows:0.06%bentonite clarifying agent, 0.08%chitosan clarifying agent, and 0.18%bentonite and chito-san mixture (their ratio was 4∶3). The best time for natural settlement treatment was 48 h. And the best time for freezing treatment was 24 h. Based on the best clarifying conditions, the clarifying effects of yellow water by different method were judged through sensory analysis, and transmittance and absorbance value analysis, and the loss of yellow water components was analyzed through physiochemical indicator analysis. As a result, chitosan clarification was determined as the best choice. Yellow water treated by chitosan clarification was clear and transparent.
