Industrial sewage treatment process and treatment apparatus

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment process, in particular relates to an industrial sewage treatment process, more specifically to an industrial sewage treatment process and a treatment device thereof. Background technique [0002] Industrial sewage treatment is mainly to remove chemical oxygen demand, suspended solids, sulfide, petroleum, cyanide, hexavalent chromium, lead and cadmium in industrial sewage, and use filtration, neutralization and purification to treat industrial sewage. Harmful substances in industrial sewage can be effectively purified by using the industrial sewage treatment device. [0003] A kind of industrial sewage treatment device disclosed in comparative document CN208265915U includes a reaction box and a filter cartridge, the bottom of the reaction box is fixedly connected with a filter box, and the left side of the bottom of the inner wall of the filter box is fixedly connected with a sleeve, and t...

AI Technical Summary

Problems solved by technology

[0004] There are certain disadvantages in the use of existing industrial sewage treatment devices. Traditional industrial sewage treatment devices do not have auxiliary cleaning structures. Traditional industrial sewage treatment devices adopt an integrated fixed structure design, which increases the difficulty of cleaning operations for industrial sewage treatment devices. ; At the same time, the traditional industrial sewage treatment device does not have a splicing fixed structure. When the user performs maintenance and disassembly operations on the industrial sewage treatment device, it increases the difficulty of installation and disassembly of the industrial sewage treatment device; at the same time, the traditional industrial sewage treatment device does not It has a docking auxiliary structure, so that a single type of industrial sewage treatment device can only be connected to the corresponding type of pipe, thereby reducing the scope of application of the industrial sewage treatment device, making it unable to apply to different types of docking pipes, which brings certain disadvantages to users influences
