The invention relates to an immobilized carrier of nano-attapulgite clay compounded hydrophilic urethane foam microorganisms, which consists of the following raw materials in parts by weight: 100 polyether, 36-55 toluene di-isocyanate, 3.1-3.9 polyisocyanate, 0.5-5 nano-attapulgite clay, 0.45-1.2 silicon oil, 0.14-0.25 tertiary amine, 0.14-0.20 organotin, 1.0-2.7 water, 1.6-4.5 methylene dichloride and 0-80 N, N-dimethylformamide. The polyisocyanate and the nano-attapulgite clay are added in the foaming process of common polyether urethane, thereby the common polyether urethane has a water absorbing surface with crosslinked network structure and strong polarity, meanwhile has great adsorption capacity and hydrophilicity of nanomaterials, improves the compatibility and the mass transfer performance of a foam carrier to the microorganism, and simultaneously strengthens the physicochemical performance and the stability of the materials, thereby improving the sewage treatment efficiency.
