Small-sized rapid precipitation environment-friendly sewage treatment device

Abstract

The invention discloses a small-sized rapid-precipitation environment-friendly sewage treatment device, which comprises a sedimentation tank, a driving motor and a filter tank; A brush plate; a drive shaft is provided under the filter plate, and spiral blades in opposite directions are provided on the left and right sides of the drive shaft. The present invention is equipped with reverse spiral blades and trapezoidal material guide plates to horizontally stir and mix the sewage and flocculants, so that the flocculants can be rapidly diffused and mixed, improving the efficiency of flocculation and sedimentation, and at the same time reducing the impact on the settled sludge. Stir to improve the efficiency of sedimentation; the present invention is provided with a reciprocating brush to avoid clogging of the filter holes and ensure normal filtering; the present invention is provided with a filter plate, a sandstone packing plate and an activated carbon packing plate that are easy to disassemble, and has better Excellent purification effect, easy to disassemble and clean.

Description

technical field [0001] The invention relates to the field of environmental protection sewage, in particular to a small-scale rapid precipitation environmental protection sewage treatment device. Background technique [0002] Sewage treatment (wastewater treatment): The process of purifying sewage to meet the water quality requirements of a certain water body for drainage or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, catering, etc., and it is also increasingly entering the daily life of ordinary people. [0003] Traditional sewage treatment facilities use grids to intercept and filter floating solid waste in sewage. More garbage is easy to block the grids, requiring manual cleaning, which is time-consuming and labor-intensive, and affects the efficiency of sewage treatment; in addition, sedimentation tanks Generally, the natura...

[0003] Traditional sewage treatment facilities use grids to intercept and filter floating solid waste in sewage. More garbage is easy to block the grids, requiring manual cleaning, which is time-consuming and labor-intensive, and affects the efficiency of sewage treatment; in addition, sedimentation tanks Generally, the natural sedimentation method is adopted in the process, and the flocculant diffuses slowly, resulting in long flocculation standing time and low sedimentation efficiency. The flow of sewage causes agitation and floating of the sludge that has settled at the bottom, which reduces the efficiency of sewage flocculation and sedimentation, and sludge cleaning is very difficult. trouble
