A sewage pretreatment device using activated carbon

Abstract

The invention discloses a device for pretreating sewage by utilizing activated carbon. The device comprises a treatment machine body, wherein a sewage tank is fixedly mounted above the treatment machine body; a sewage cavity with an upward opening is formed in the sewage tank; the vertical part of one side below the sewage cavity is communicated with an impurity channel; the horizontal part of theother side of the impurity channel is connected with the outside of the right treatment machine body; a filtering device is arranged in the impurity channel; and the filtering device comprises a bevel gear transmission groove located in the left side of the impurity channel. A connecting lead screw is arranged between the bevel gear transmission groove and the impurity channel in a rotating fit mode, the connecting lead screw is located in the impurity channel and is in threaded connection with an impurity pushing block, and the connecting lead screw rotates to drive the impurity pushing block to rotate so as to push out large impurities.

Description

technical field [0001] The invention relates to the technical field of water pollution treatment, in particular to a sewage pretreatment device using activated carbon. Background technique [0002] With the development of social construction, the water produced in rural towns has also increased significantly. These waste water generally need to be treated to a certain extent before being discharged into the natural environment. Nowadays, many people directly use activated carbon to absorb impurities in water, and the amount of activated carbon is not good. To grasp the situation, if too little activated carbon is used, the absorption will be incomplete, and too much input will cause waste. At the same time, the sedimentation of activated carbon is too slow. It is very important to invent a sewage treatment device that can quantitatively input activated carbon and speed up the absorption of activated carbon. Contents of the invention [0003] The object of the present inven...
