A concise introduction of the background of experiments on mileumycinum res
earch is given. It is followed by a description of the system reconstructab
ility analysis model. In this model the alternatives of macroreticular resi
n, the concentration of filtrate, and the pH value are factors. The ratio b
etween concentration of adsorbed waste water and filtrate, and synthetical
criterion of extraction and purification are the criteria. The results are
computed by the ELEREB program, which was produced by Guangfu Shu. The orde
r of factor and criterion levels determined by behavior function closeness
are given. On this basis optimal results are presented. Finally, proposals
for further studies are listed.
