1. 5由于聚合物驱污水中HPAM的存在使污水黏度增加，导致污水处理更加困难，利用光催化法对HPAM降黏进行了研究，首次提出光降黏的概念。
The presence of HPAM causing the wastewater become viscously which increasing the difficulty in treatment. In the paper, the photocatalytic visbreaking for HPAM wastewater was investigated.

3. 通过实验可以看出，光降解法对氯代乙酸也有较好的去除效果，并且较之于光催化方法更加便宜、方便。
It can be seen from the results that the conversion efficiencies of photolytic degradation of chloroacetic acids are also quite high and the photolytic degradation method is more convenient and cheaper than the Photocatalytic degradation method.
