The invention discloses an industrial sewage treatment process. The process comprises the operation steps of adjusting operation, primary filtering, secondary filtering, decoloring operation, and water discharge treatment. The specific steps are as follows: step one, adjusting operation: a sealing round cover of a water storage tank is opened, so that the water storage tank is connected with a water discharge pipeline of industrial sewage, so that the industrial sewage enters the water storage tank, an acidic solution is added into the water storage tank, a rotation rod of the water storage tank is driven by a rotation hand wheel, and at the same time an alkaline solution is added into the water storage tank, the rotation hand wheel is driven to make the alkaline solution mix with the industrial sewage to adjust a pH value of the industrial sewage; and step two, primary filtering: the industrial sewage in the water storage tank is pumped through a water suction pump, so that the industrial sewage enters a filtering tank through connecting pipes. According to the industrial sewage treatment process and treatment apparatus, the industrial sewage treatment apparatus has a spliced combined fixed structure, the difficulty of maintenance operations of the apparatus is reduced, and at the same time, the industrial sewage treatment apparatus has a docking auxiliary structure, so that the flexibility of the industrial sewage treatment apparatus in use is improved.
