The invention discloses laboratory organic waste liquid treatment method and system, and belongs to the technical field of environmental protection equipment. The treatment method comprises the following steps: (1) collecting and temporarily storing the organic waste liquid in a laboratory; (2) adjusting the pH value; (3) precipitating the liquid; (4) flocculating and settling the liquid; 5) performing reverse osmosis; 6) performing oxidization; and 7) performing after-treatment; wherein the treatment system comprises a collection tank, a classified temporary storage tank, a neutralization tank, a sedimentation tank, a flocculation tank, a sedimentation tank, a reverse osmosis tank and a superoxide tank, which are connected in sequence. According to the method and the system, the organic waste liquid in the laboratory is fully treated step by step through acid-base neutralization, precipitation, flocculation, sedimentation, reverse osmosis and supercritical oxidation, so that the treatment efficiency is high,
