The invention relates to a highly-molecular separation membrane, in particular to a high-throughput polyamide reverse osmosis composite membrane. In the high-throughput polyamide reverse osmosis composite membrane, a polyamide ultra-thin functional layer is compounded on a porous supporting membrane by interfacial polycondensation between water solutions of aromatic polyamine and aliphatic macromolecular polyamine and a solution of aromatic poly-acyl chloride, wherein the aromatic polyamine at least comprises one of metaphenylene diamine, 4-chloro metaphenylene diamine, 4-nitryl metaphenylenediamine and 2,4-diaminotoluene; the aromatic poly-acyl chloride is trimesoyl chloride, 5-isocyanate-isophthaloyl chloride or 5-chloroformloxy-isophthaloyl chloride; and the aliphatic macromolecular polyamine is polyvinylamine. The reverse osmosis composite membrane has the advantages of readily available raw materials, low cost, high desalination rate and high throughput. The novel high-throughput polyamide reverse osmosis composite membrane is wide in application and the preparation method is simple.
