Problems solved by technology

[0003] In addition to industrial sewage, rural sewage is also one of the major sewage sources. However, since most of the houses in rural areas of our country are relatively scattered and far away from nearby towns, it is very inconvenient to directly incorporate them into urban sewage plants, and the existing technology cannot fully meet the current situation. In some cases, the sewage can only be roughly decontaminated by sewage treatment equipment, and the sewage cannot be efficiently and thoroughly treated. Therefore, the present invention proposes a rural sewage treatment biofilter to solve the above problems

Embodiment 1

[0022] see Figures 1 to 4 , In the embodiment of the present invention, a biological filter tank for rural sewage treatment includes a treatment tank 26, and the treatment tank 26 is provided with a sedimentation chamber, a purification tank and a purification tank from top to bottom through the first partition 4 and the second partition 9 The silo and the sterilization silo, the upper part of the sedimentation silo is open, and two threaded rods 16 are installed in the precipitation silo through the bearing in front and back symmetrically and rotatably, and a movable seat 17 is passed between the two threaded rods 16. 16 are all adapted threaded connections, a drive motor 20 is fixedly installed on the side wall of the precipitation chamber, the drive motor 20 is a square rotary motor, and the output shaft of the drive motor 20 extends into the precipitation chamber and is connected with the two threads. One end of the rods 16 is connected to each other, and the two threaded...

Embodiment 2

[0027] Further, in order to prevent the dirt in the sewage from adhering to the wall of the water inlet pipe 14 and causing poor water flow, the water inlet pipe 14 is located in the pipe section between the coarse filter screen 27 and the sedimentation chamber. Two mounting rods are fixedly arranged. 28. A rotating rod 29 is rotatably installed between the two mounting rods 28. The side of the rotating rod 29 is provided with a plurality of strip-shaped brushes 31 at equal distances in the circumferential direction through a plurality of supporting rods 30. The brush surface is in contact with the inner wall of the water inlet pipe 14, and the rotating rod 29 is fixed with a driving screw 32. When the sewage enters the sedimentation tank through the water inlet pipe 14, the water flow drives the driving screw 32 to rotate, thereby making the rotating rod 29 rotate, and the rotating rod 29 While rotating, a plurality of strip-shaped brushes 31 are driven to rotate along the inn...

Abstract

The invention discloses a rural sewage treatment biofilter which comprises a treatment tank, a sedimentation bin, a purification bin and a disinfection bin are sequentially arranged in the treatment tank from top to bottom through a first partition plate and a second partition plate, two threaded rods are symmetrically and rotatably mounted in the sedimentation bin through bearings front and back,and a movable base is arranged between the two threaded rods in a penetrating mode; a storage box is fixedly arranged on the movable base, a discharging box is arranged below the movable base, a finefilter screen is arranged on the lower portion of an inner cavity of the sedimentation bin, a quartz sand filter layer is further arranged between the fine filter screen and the second partition plate, a flow dividing box and a honeycomb type biological filler frame are sequentially arranged in the purification bin from top to bottom, and a first water outlet is formed in the second partition plate; the end, away from the second partition plate, of the first water outlet extends into the flow dividing box. The biofilter is simple and reasonable in structural layout, convenient to use, capableof rapidly and efficiently purifying sewage, high in efficiency and good in effect, completely meets the harmless discharge standard, and has important practical significance for rural sewage treatment.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a biological filter for rural sewage treatment. Background technique [0002] With the development of industry, the composition of sewage has become more and more complex. Some refractory organic substances and toxic substances need to be treated by microbial methods. Sewage has the conditions for microbial growth and reproduction, so microorganisms can obtain nutrients from sewage. , At the same time degrade and utilize harmful substances, so as to purify sewage, biological wastewater treatment is to use the life activities of microorganisms to degrade organic pollutants in dissolved or colloidal state in wastewater, so as to purify wastewater. A treatment method , Wastewater biological treatment technology is favored by people for its obvious advantages such as low consumption, high efficiency, low cost, convenient and reliable process operation and management, and no ...
