Rural residents have different living styles, diets, and hygiene habits from cities, so that rural sewage contains more solid waste, such as leftovers, leftovers, leaves, sludge, etc. For these wastes, generally use grilles to intercept them. Under the action of a large amount of waste, the grille is prone to blockage and breakage, which will affect the treatment of sewage

Embodiment 1
[0055] The embodiment of the present application discloses a pretreatment device for rural sewage. refer to figure 1 , comprising a collection mechanism 1, a first separation mechanism 2 is arranged downstream of the collection mechanism 1, a crushing mechanism 3 and a first sedimentation mechanism 4 are arranged downstream of the first separation mechanism 2, and a fermentation mechanism 5 is arranged downstream of the crushing mechanism 3. A second separation mechanism 6 is arranged downstream of the first sedimentation mechanism 4 , an aerobic mechanism 7 is arranged downstream of the second separation mechanism 6 , and a second sedimentation mechanism 8 is arranged downstream of the aerobic mechanism 7 . The sewage settles in the collecting mechanism 1, and produces sediment and oily waste water. The sediment passes through the first separation mechanism 2 to form muddy water and solid waste, and the solid waste is discharged after passing through the crushing mechanism 3...
Embodiment 2
[0074] The embodiment of the present application discloses a pretreatment method for a rural sewage pretreatment device, including the following steps:
[0075] The sewage is collected and deposited for the first time by the collection mechanism 1, producing oily waste water and sediment;
[0076] The sediment is separated by the first separation mechanism 2 to generate muddy water and solid waste;
[0077] The solid waste is crushed by the crushing mechanism 3 to produce muddy water and crushed solid waste;
[0078] The crushed solid waste is fermented through the fermentation mechanism 5;
[0079] Mix the oily wastewater generated by the collection mechanism 1, the muddy water generated by the first separation mechanism 2, and the muddy water generated by the crushing mechanism 3, and conduct second precipitation through the first sedimentation mechanism 4 to generate sludge and oily wastewater;
[0080] The oily waste water is separated by the second separation mechanism ...

Abstract
The invention relates to the technical field of sewage pretreatment, and particularly discloses a pretreatment device and a pretreatment method for rural sewage. The pretreatment device comprises a collection mechanism, a first separation mechanism, a first precipitation mechanism, a crushing mechanism, a fermentation mechanism, a second separation mechanism, an aerobic mechanism and a second precipitation mechanism, wherein the collection mechanism comprises a collection box body, a first discharging pipe, a feeding pipe and a first discharging pipe; the first separation mechanism comprises a first collection box body, a driving shaft, a first spiral conveying blade, a third motor and a second discharging pipe, a discharging opening is formed in the bottom of the feeding end of the first collection box body, a first filtering plate is fixedly arranged at the position, located at the discharging opening, of the first collection box body, and a second discharging pipe is arranged at the position, located at the discharging opening, of the first collection box body; and the crushing mechanism comprises a crushing box body, two crushing rollers, a fourth motor, a filtering assembly, a third discharging pipe and a third discharging pipe. According to the pretreatment device, solid waste in sewage can be conveniently removed, and the influence of the solid waste on sewage treatment is reduced.
Description
technical field [0001] The present application relates to the technical field of sewage pretreatment, in particular to a pretreatment device and method for rural sewage. Background technique [0002] With the development of society and economic progress, people's awareness of environmental protection has been continuously strengthened. However, due to the large population in rural areas and the long-term lack of infrastructure, the problem of environmental pollution in rural areas has become more and more prominent. Rural residents have different living styles, diets, and hygiene habits from cities, so that rural sewage contains more solid waste, such as leftovers, leftovers, leaves, sludge, etc. For these wastes, generally use grilles to intercept them. Under the action of a large amount of waste, the grille is prone to blockage and breakage, which will affect the treatment of sewage. Contents of the invention [0003] In order to reduce the impact of solid waste on sewa...
