Suspension microorganism carrier and its preparation method

A suspended microbe carrier with high microbial affinity, adsorption and hydrophilicity is a macroreticular skeleton and millipore skeleton combined structure. Its preparing process includes such steps as preparing the aqueous solution of polyvinyl alcohol, proportionally adding sulfuric acid and formaldehyde solution, reaction, adding powdered imorganic filler, high-speed stirring, filling it in a mould, foaming by filling the pre-heated air via millipore air distributor, and treating at 40-80 deg.C for 4-24 hr.
