1. A mechano-chemical wastewater treatment equipment to treat wastewater containing heavy metals to form a drainage, comprising:
an intermediate sewage tank to store the wastewater to be treated and sewage formed during a treatment process, the intermediate sewage tank comprising a sewage inlet and a sewage outlet;
at least one mechano-chemical reactor, wherein the at least one mechano-chemical reactor comprises a ball milling device and is configured to receive wastewater containing heavy metals, balls for a ball milling treatment, and zero-valent iron nanoparticles, wherein said at least one mechano-chemical reactor is configured to carry out a mechano-chemical reaction between the wastewater and zero-valent iron nanoparticles through the ball milling treatment, said at least one mechano-chemical reactor comprises:
a reactor shell with a reaction chamber internally formed, the reactor shell comprising a feeding inlet to allow a slurry to enter said reaction chamber and a discharge outlet to allow said slurry to flow out of said reaction chamber;
a rotor, which is set inside said reaction chamber; and
a driving mechanism to drive a rotation of said rotor; and
a separator, utilized for solid-liquid separation of said slurry produced by said at least one mechano-chemical reactor, the separator comprising a slurry inlet for said slurry to enter from said discharge outlet, a liquid outlet for separated liquid to flow out, and a sludge outlet for a separated sludge to flow out; and
wherein said sewage outlet is connected to said feeding inlet, said liquid outlet is connected to said sewage inlet, said sludge outlet is connected to said feeding inlet, and said slurry inlet is connected to said discharge outlet.
