An environmentally friendly sewage treatment device that is easy to maintain

Abstract

The invention discloses an environmentally friendly sewage treatment device which is convenient for maintenance, comprising a stirring box, a box cover is fixedly connected to the top of the stirring box, a rotating shaft is fixedly connected to the middle of the inner cavity of the box cover, and one end of the rotating shaft is located inside the stirring box, The outer wall of one end of the rotating shaft is fixedly connected with a fixing seat, the middle part of the inner cavity of the fixing seat is fixedly connected with a nut, the inner thread of the nut is sleeved with a threaded rod, and the end of the threaded rod away from the nut is fixedly connected with a stirring block, and the stirring block is located in the mixing box. internal. This environmentally friendly sewage treatment device is easy to maintain. Through the cooperation between the box cover, the rotating shaft, the fixed seat, the nut and the threaded rod, the replacement of the stirring block is completed by twisting the threaded rod, so that the replacement of the stirring block is more convenient. The stirring block can be replaced quickly, thereby saving a lot of time for replacing the stirring block, improving the working time of the sewage treatment device, and improving the working 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 environment-friendly sewage treatment device that is easy to maintain. Background technique [0002] Sewage, usually refers to certain polluted discharge water from domestic 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 will be filtered by the sewage treatment device before being discharged. [0003] Since most of the sewage contains heavy metals, the sewage treatment device needs to replace the heavy metals by stirring the reaction liquid with the sewage, and then filter them, so that the sewage can b...
