The results show that it is reasonable to improve the technology by replacing the paper pulp with the Kieselguhr filter aid.

结果表明，采用硅藻土助滤剂代替纸浆过滤的工艺改进是合理的。

The order of Df (desorption factor) value was: yellowish red soil>silt-loamy soil>kaoline>perlite>paddy soil (loamy clay) >kieselguhr.

解吸因数的大小排列顺序为：黄红壤、粉泥土、高岭土、珍珠岩、青紫泥、硅藻土。

And after the treatment of this process, the supported Cu kieselguhr could be reused, or could be used as the effective catalysts in the organic oxidation reaction.

负载铜硅藻土在除钒处理后，可以再生，或作为有机催化氧化反应的有效催化剂。
