The invention discloses a visible detection method for heavy metal uranium pollution. The visible detection method comprises the following steps: (1) inoculating red serratia marcescens and rosy kocuria kristinae to two triangular flasks containing TGY liquid culture mediums, and culturing so as to obtain rosy kocuria kristinae fermentation broth and red serratia marcescens fermentation broth; mixing the rosy kocuria kristinae fermentation broth and the red serratia marcescens fermentation broth so as to obtain a heavy metal uranium microorganism detection system; (2) adding a TGY oligotrophic culture solution into a sample to be detected, inoculating into the heavy metal uranium microorganism detection system, and culturing; detecting the numbers of red serratia marcescens and rosy kocuria kristinae in the sample to be detected by using a dilution coating method, and judging the heavy metal uranium pollution situation of the sample to be detected. As the red serratia marcescens and the rosy kocuria kristinae are taken as a sensitive bacterium and a resistant bacterium of heavy metal uranium, visible detection can be effectively achieved through different colors.
