This paper introduced the function and the processing flow diagram of diatomite filtration——the whole process of film coating beforehand,filtration and backwashing.

This paper introduced the automatic control system of the diatomite filter ,which based on the core of the ACMY-S80 PLC,according to the working principles of the diatomite filter and it s control characteristics.

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.

Effect of diatomite on water resistance of asphalt mixture;

The addition of diatomite can improve the physical-mechanical performance of asphalt mixture and enhance the quality of pavement engineering.

On the basis of the laboratory test of the road performance of the asphalt mixture modified by diatomite,an experiment road was built in Jiangsu Province for the comparison of the diatomite modified asphalt mixture with the ordinary asphalt mixture to discuss the feasibility of the application of diatomite modified asph.
