Environment-friendly sewage treatment device convenient for maintenance

Abstract

The invention discloses an environment-friendly sewage treatment device convenient for maintenance. The sewage treatment device includes a stirring box, the top of the stirring box is fixedly connected to a box cover, a rotation shaft is fixedly connected to the center of the box cover cavity, and one end of the rotation shaft is located in the stirring box, the outer wall at one end of the rotation shaft is fixedly connected to a fixed seat, the center of the fixed seat cavity is fixedly connected to a nut, a threaded rod is threadedly sheathed in the nut, one threaded rod end far from the nut is fixedly connected to a stirring block, and the stirring block is located in the stirring box. According to the environment-friendly sewage treatment device convenient for maintenance provided by the invention, through cooperation of the box cover, the rotation shaft, the fixed seat, the nut and the threaded rod, the stirring block can be replaced by screwing the threaded rod, therefore replacement of the stirring block becomes more convenient and is fast, thus saving a lot of stirring block replacement time, improving the working time of the sewage treatment device, and enhancing the work efficiency of the sewage treatment device.

Description

Technical field [0001] The invention relates to the technical field of sewage treatment equipment, in particular to an environmentally friendly sewage treatment device that is convenient for maintenance. Background technique [0002] Sewage usually refers to certain polluted water discharged from life and production. Sewage mainly includes domestic sewage, industrial wastewater and initial rainwater. The main pollutants of sewage include pathogen pollutants, oxygen-consuming pollutants, plant nutrients and toxic pollution. If the sewage is discharged directly into the river without treatment, it will easily cause the river to be polluted and affect the natural environment. Therefore, the current sewage is filtered by the sewage treatment device before it is discharged. [0003] Since most of the sewage contains heavy metals, the sewage treatment device needs to replace the heavy metals through the reaction liquid and the sewage after stirring and reacting, and then filter it, so th...
