Abstract
A method for modifying a wastewater treatment device, the method including: 1) fixing a filling support in a wastewater pool, where the filling support includes a support frame; the support frame includes a hollow shaft, a fixed ring, and at least one vane; 2) adjusting the height of the filling support, until the fixed ring is submerged below the liquid level of the wastewater pool, where the water intake velocity of the wastewater pool is no less than 0.25 m/s, whereby a water current is produced and drives the support frame to rotate; 3) adding a functional liquid into the hollow shaft; and 4) adding an enzyme mixture to the hollow shaft when the rotation speed of the support frame is less than a first preset value, until the rotation speed of the support frame reaches a second preset value.
