Claim 0:
1. A metabolic enzyme-induced micro-nano plastic particle biodegradation method, comprising the following steps:
step (1), cutting an appropriate quantity of plastic products into small pieces;
step (2), placing the plastic products in a ball mill tank and milling the plastic products in a vacuum in a ball mill;
step (3), weighing and dispersing milled plastic products with water to prepare a micro-nano plastic dispersion with a concentration;
step (4), mixing the micro-nano plastic dispersion with a metabolic enzyme solution in a mass ratio range of a metabolic enzyme mixed with micro-nano plastics of 0.00000001-10000, and placing a mixed solution in a vortex oscillator for mixing well, wherein the metabolic enzyme comprises glutathione S-transferase; and
step (5), incubating the mixed solution in a waterproof incubator.
