Working method of sewage treatment device

Abstract

The invention relates to the field of sewage treatment and in particular relates to a working method of a sewage treatment device. The sewage treatment device comprises a sewage precipitation mechanism, a dyestuff adsorption mechanism and a disinfection mechanism, wherein the dyestuff adsorption mechanism is arranged between the sewage precipitation mechanism and the disinfection mechanism; the sewage precipitation mechanism comprises a precipitation tank, an impurity discharging assembly, a cleaning assembly and a first filter screen; a discharging funnel communicated with the inner part of the precipitation tank is arranged at the bottom of the precipitation tank; a discharging pipeline is arranged at the bottom of the discharging funnel; the impurity discharging assembly comprises a lifting plate, an impurity collection part and a material movement part. The working method of the sewage treatment device, provided by the invention, has the beneficial effects that the filtering assembly can be automatically lifted through a lifting assembly so that a worker can conveniently replace an activated carbon adsorption plate in a filtering assembly.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a working method of a sewage treatment device for printing and dyeing. Background technique [0002] A large amount of wastewater will be generated during the printing and dyeing process. If it is discharged directly without treatment, it will have a great impact on the surrounding environment. The traditional printing and dyeing wastewater treatment methods are mostly the process of sedimentation and disinfection in the sedimentation chamber. The traditional treatment method is It is not thorough enough, and it is difficult to collect the impurities after treatment. [0003] The patent No. CN107352693A discloses an efficient sewage treatment device for printing and dyeing, which includes a primary sedimentation chamber. A sedimentation box is clamped inside the primary sedimentation chamber. The bottom of the sedimentation box is fixedly connected with a first filter screen. The ...

Problems solved by technology

[0004] Although this invention can prevent impurities from entering the secondary precipitation chamber, it does not mention the collection and treatment of impurities, so that workers need to additionally deal with impurities; If the impurities on the net are not treated for a long time, the filter holes of the filter will be blocked, which will affect the work of the filter.

[0005] Moreover, the activated carbon adsorption plate needs to be maintained regularly, and the manual disassembly of the activated carbon adsorption plate is cumbersome, which brings difficulties to the workers.
