There are four kinds of polymer drugs which are the pharmacological activities polymer, the polymer complex drug, the polymeric carrier drug microsphere and the polymer carrier drugs.

Biological nitrogenou compound removal with porous carrier particles;

To minimize the losses of the product quality, drying of biomass with porous carriers was applied.

Based on the comprehensive review about the study on photocatalyer all over the world, the problems about the carrier, especially about the porous carrier, and the carrying method are analyzed and discussed.

In the process of wastewater treatment, biofilm detachment in an anaerobic fluidized bed with polymer porous carriers(WAR-8-8) has been studied, and the concentration has been put on the factors influencing biofilm detachment and biofilm detachment process.

And a dynamic circular bioreactor is developed on the basis of the theory to investigate whether the sludge in the porous carriers has been decompounded in anaerobic environment or not.

Porous carriers are suitable for culture both anchorage dependent and anchorage independent animal cells,capable of increasing unit cell density and using in scaled up systems.
