Sewage treatment device

Abstract

The invention discloses a sewage treatment device which comprises a treatment pond. One side of the treatment pond is communicated with a feeding pipe, the side, away from the feeding pipe, of the treatment pond is communicated with a discharging pipe, the bottom of the inner side of the treatment pond is fixedly connected with a precipitation frame, and the outer side of the discharging pipe is provided with a filtering frame. The position, close to the filtering frame, of the outer portion of the discharging pipe is sleeved with a bearing, the side, away from the discharging pipe, of the filtering frame communicates with a discharging pipe, a separation device is installed in the filtering frame, a filtering device is installed on the inner wall of the filtering frame, and a clearing device is installed on the position, close to the filtering device, of the inner wall of the filtering frame. A motor is mounted outside the filtering frame. The invention relates to the technical field of sewage treatment. According to the sewage treatment device, the purpose of deeply filtering sewage is achieved, the contact area of the filter screen can be changed along with the size of water flow, and the sewage treatment efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment device. Background technique [0002] At present, in the field of sewage filtration, especially in the preliminary filtration system for removing sewage particulate impurities, filter screens are generally used for primary filtration; however, in some sewage pipes with unstable water quality, the mesh size of the filter screen is difficult to grasp. If the mesh is too fine, the filtration speed will be slow; if the mesh is too large, there may be no filtering effect at all; and in order to ensure the filtering effect, a finer mesh is generally used to adapt to the filtration of finer particles. ; In this way, the efficiency of this kind of system is very low when filtering coarser impurity particles. [0003] For example, the Chinese patent CN105561660B proposes a sewage filtration system, including a filter pipe, and the inside of the filter pipe is ...

Problems solved by technology

[0004] This device cannot achieve the purpose of cleaning the filter screen in time, and cannot avoid excessive impurities to block the filter screen, which affects the normal operation of subsequent filtration work. When filtering sewage, it cannot achieve multiple deep filtration. The structure is single and solid-liquid separation cannot be achieved. For the purpose, the quality of the filtered liquid is not high, and the slow speed of the filter affects the efficiency of the filter
