This paper reported the control effect with some new technologies of "affusing pesticide and covering film method" , "diatomite handling method" and "kill termite ring method" for controlling Odontotermes formosanus and Reticulitermes chinensis which damage the garden trees.

Application of diatomaceous earth to Deodorized Paper;

Chromic wastewater treatment by diatomaceous earth as absorbent;

Study on the filtration by diatomaceous earth in the TiO_2 production;

Based on the productive test,the combined process of high-voltage pulse electrocogulation and refined diatomite was used to treat electroplating comprehensive wastewater.

The contaminant removal mechanism of refined diatomite technology and its application in China were introduced.

The refined diatomite was used to treat industrial wastewater from a circuit board plant.

The effluent of wastewater treatment plant is treated by combing diatom earth and biological contact oxidation process.

Basic performances of several non-metallic minerals,in terms of bentonite,diatom earth,kaolin and rectorite,and applications thereof in construction paints are introduced.

This paper narrates the effect and the demand of titanium liquid filter aid; and introduces the use of diatom earth filter aid in the manufacture of titanium white by sulfuric acid method.
