Embodiment 1

[0027] see figure 1 and 3 , in the embodiment of the present invention, a filter-type rural sewage treatment device includes a treatment box 7, a cylindrical cavity 8 is provided in the middle of the treatment box 7, and an annular cavity 5 is provided on the outside of the treatment box 7, so that The middle part of the cylindrical cavity 8 is equipped with a middle connecting pipe 11, and the upper and lower ends of the middle connecting pipe 11 are respectively equipped with an upper filter net tube 9 and a lower filter net tube 14, and the outer side of the middle connecting tube 11 is also circumferentially A plurality of horizontal drainage cylinders 3 are distributed and installed, and a stirring assembly is installed corresponding to the horizontal drainage cylinder 3 on the middle connecting pipe 11. A vertical settling cylinder 4 is installed on the lower side of the horizontal drainage cylinder 3 in the annular cavity 5, and the horizontal drainage cylinder 3 and t...

Embodiment 2

[0031] see Figure 1-5 , the difference between this embodiment and embodiment 1 is:

[0032] In this embodiment, the cylindrical cavity 8 is a cylindrical structure, the annular cavity 5 is a circular structure, and the upper end surface of the annular cavity 5 is located on the lower side of the upper end surface of the cylindrical cavity 8; figure 2As shown, the upper filter cylinder 9 and the lower filter cylinder 14 are arranged symmetrically up and down, and the upper filter cylinder 9 is a tapered cylinder structure with a large upper part and a smaller lower part. The upper end is fixed on the top outer ring of the cylindrical cavity 8, and the lower end of the lower miscellaneous filter screen tube 14 is fixed on the bottom outer ring of the cylindrical cavity 8; The middle connecting pipe 11 and the lower miscellaneous filter cylinder 14 are coaxially arranged to improve the treatment effect of sewage.

[0033] The horizontal drainage cylinder 3 is arranged horizo...

Abstract

The invention relates to the field of rural sewage treatment, in particular to a filtering type rural sewage treatment device which comprises a treatment box body, a cylindrical cavity is formed in the middle of the treatment box body, an annular cavity is formed in the outer side of the treatment box body, a middle communicating pipe is installed in the middle of the cylindrical cavity, and an upper impurity filtering net barrel and a lower impurity filtering net barrel are installed at the upper end and the lower end of the middle communicating pipe respectively. A plurality of transverse drainage cylinders are further circumferentially distributed and installed on the outer side of the middle communicating pipe, stirring assemblies corresponding to the transverse drainage cylinders areinstalled on the middle communicating pipe, vertical sedimentation cylinders are installed on the lower sides of the transverse drainage cylinders in the annular cavity, and compact filter screens areinstalled on the sides, away from the middle communicating pipe, of the connecting positions of the transverse drainage cylinders and the vertical sedimentation cylinders; ultraviolet disinfection lamp tubes are further arranged on the sides, away from the middle communicating pipe, of the compact filter screens, and elastic buffer devices are further installed on the outer sides of the ends, away from the middle communicating pipe, of the transverse drainage cylinders. The sewage treatment device can perform graded filtration on sewage and reliably mix chemicals, and is good in sterilizationand disinfection effect, reliable in sewage treatment and worthy of popularization.

Description

technical field [0001] The invention relates to the field of rural sewage treatment, in particular to a filtering type rural sewage treatment device. Background technique [0002] Sewage refers to the discharged water from life and production that has been polluted to a certain extent. The water that has lost its original use function is referred to as sewage for short, and it is mainly water after domestic use. From the viewpoint of the source of sewage, sewage can be defined as waste-carrying liquid or water discharged from residential, institutional, commercial or industrial areas mixed with groundwater, surface water, snowstorms, etc. [0003] Rural domestic sewage treatment is to remove and degrade harmful substances and environmental pollution components in domestic sewage for harmless treatment. Rural domestic sewage treatment should focus on the selection of mature and reliable technologies suitable for rural characteristics and actual sewage treatment. Rural sewag...
