It is very difficult to reach an efficient separation for microne and submicrone of liquidsolid and gas-solid mixtures. The efficiency of tranditional separation methode to be applied in industries up to date are all not high. A new separation technology——sintered polymer fine microporous filteration technology (consisting of sintercd microporous filtration media, fine microporous filter, auxiliary equipments and sarious application methods) are offered in this paper. Which can give an efficient separation for the liquidsolid mixtures and gas-solid mixtures of microns and submicrons. In addition to the high filtration efficiency, the operation are simple and conrenient, the land area occupied are less, the service life are long and the cost of operation and investment are lower. This technology has been applied in various industries for proluctions and waste water widely.

In this paper,a beady gel filtration media was obtained by cross linking allyl dextran with N,N′ methylenebisacrylamide by means of suspension copolymerization. Properties of chromatography separation, chemical and physical stabilities of the gel were investigated. The media dispalys excellent separation characteristics, and is both chemically and physically stable. The results of tests, where the gel was exposed to various commonly used buffer in biochemistry for one week at 25 ℃, showed that significant change was not found in the chromatographic properties of the gel in most cases. It was also observed that the gel had notable thermal stability and good inherent rigicity.
