Abstract

The invention relates to the technical field of sewage treatment equipment, and discloses a sewage treatment apparatus capable of preventing box breakage. The sewage treatment apparatus comprises a box. The movable openings in the outer wall of the box are fixedly connected to a circular column. A support column is arranged in the circular column movably. One end of the support column is fixedly connected to a buffer block. The buffer block is arranged in the box. The external side of the support column is movably connected to a spring. One end of the spring is fixedly connected to one side ofthe internal wall of the box. The end, which is far from the internal wall of the box, of the spring is fixedly connected to the external side of the buffer block. Through the cooperation among the box, the circular column, the support column, the buffer block, and the spring, the buffer block can move the spring horizontally so as to minimize the impact force of sewage on the buffer block, the impact force on the buffer block is minimized, the buffer block and the box will not be broken, the service life of the box and the buffer block is prolonged, and the sewage in the box will not flow out and pollute the environment.

Description

technical field

[0001] The invention relates to the technical field of sewage treatment equipment, in particular to a sewage treatment device capable of preventing a box from breaking. Background technique

[0002] Sewage, usually refers to some polluted and 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. These sewage are usually treated before being discharged into the river, so as to ensure that the sewage will not pollute the natural environment.

[0003] Most of the currently used sewage treatment devices first perform coarse filtration to remove impurities in the sewage, and then add a reaction solution to the sewage to replace the heavy metal elements in the sewage. After adding the reaction solution to the sewage, the mixed liquid of the sewage and the reaction so...
