The invention belongs to a treatment method, and particularly relates to a treatment method of waste liquid containing organic matters and radionuclides. The method comprises the following steps of 1) pretreating waste liquid to be treated, namely adjusting the pH value of the waste liquid and filtering, and controlling the waste liquid to be treated to be free of solid impurities or organic floccules, 2) introducing the treated waste liquid to be treated into a device filled with an activated carbon adsorbent, or directly adding activated carbon into the waste liquidto be treated for stirring adsorption, and 3) introducing the waste liquid subjected to organic matter removal through activated carbon treatment into the device filled with the silica gel adsorbent again, or directly adding activated carbon into the waste liquid to be treated for stirring adsorption, wherein two or more stages of adsorption devices can be selected according to the processed result; the content of organic matters and the content
