Description

Technical Field

[0001] The present invention relates to the field of sewage treatment equipment, and in particular to a domestic sewage resource recycling device. Background Art

[0002] The resource utilization of domestic sewage refers to the harmless treatment of sewage to meet specific water quality standards, which is used as recycled water to replace conventional water resources for industrial production, municipal miscellaneous uses, residents' lives, ecological water replenishment, agricultural irrigation, and groundwater recharge. With the acceleration of my country's urbanization process, the total amount of sewage discharge is also increasing rapidly, and the construction of corresponding sewage treatment plants is also developing rapidly. Urban residents and factories are concentrated and have a high degree of modernization. Sewage is generally concentrated in sewage treatment plants through pipes for treatment. However, the concentration of rural residents is not as high as that of cities, and the courtyards are scattered. The cost of laying sewage pipes is high, and the difficulty of centralized sewage treatment is high. Domestic sewage is rich in nitrogen, phosphorus, and potassium. Indiscriminate discharge can easily cause eutrophication of water bodies.

[0003] Under the guidance of the current social development concepts of "energy conservation and emission reduction" and "resource conservation and environmental friendliness", most people gradually realize that sewage treatment is imperative. However, the existing underground integrated sewage treatment equipment is costly and energy-intensive, which is too costly for rural areas with limited financial resources and low income.

[0004] Rural domestic sewage generally does not contain heavy metals, etc., and the treatment technology is not difficult. Therefore, our company aims to design an economical, simple, effective domestic sewage treatment equipment that can be integrated with local agricultural production as much as possible to achieve harmless treatment and resource utilization of sewage.

A connecting channel is provided at the bottom of the water seepage plate 31, and a plurality of sewage inlet pipes 11 are provided on the side of the box body 1 close to the first filter area 4. Sewage enters from the sewage inlet pipe, is first filtered in the first filter area, and then reaches the second filter area through the connecting channel. It permeates and filters upward under the action of evaporation, capillary phenomenon, etc., and is finally used or stored by plants, thereby completing the resource recycling of domestic sewage.

[0030] The first filter area 4 is provided with a first filter assembly 5 that can be removed as a whole, which is convenient for replacement. The first filter assembly includes a coarse grid 54, a fine grid 53, a fruit shell filter material box 52 and a sedimentation tank 51 from top to bottom. The sedimentation tank 51 is placed in the box body 1, the filter material box 52 is placed on the sedimentation tank, and the fine grid 53 is placed on the filter material box 52. The coarse grid 54 is tilted, and the side with a low height is placed on the fine grid 53. The low side and the front and rear sides of the coarse grid 54 are provided with baffles 541, which try to prevent sewage from splashing onto the inner wall. The side wall of the sedimentation tank 51 close to the partition plate is provided with an overflow interlayer 511. The first filter area 4 is connected to the second filter area 3 through the overflow interlayer 511 and the connecting channel. The sewage is filtered through the coarse grid, the fine grid and the fruit shell filter material box, precipitated in the sedimentation tank, and overflowed from the overflow interlayer to the connecting channel. Among them, the fruit shell filter material has a strong ability to absorb and remove dirt and oil, and can filter most of the oil.

[0031] The second filter area 3 is provided with a second filter assembly 6 that can be removed as a whole. The second filter assembly includes a stuffing box 69, filter material and a cushion net 68. The stuffing box 68 is placed on the seepage plate 31. The filter material is located in the stuffing box and is divided into several layers by the cushion net 68. Soil 8 is laid on the top layer of filter material. The sewage is purified by the filter material, and the filter material can be taken out as a whole through the stuffing box for recycling and reuse.

[0032] As a preferred embodiment, two lifting holes are provided in the middle positions of the coarse screen 54, the fine screen 53, the fruit shell filter box 52 and the sedimentation tank 51. The lifting holes on the coarse screen 54, the fine screen 53 and the sedimentation tank 51 are threaded holes, and two lifting rods 56 are provided in the lifting holes, and the first filter assembly 5 is taken out as a whole through the lifting rods 56.

[0033] As a preferred embodiment, two second lifting rods 66 are fixed in the stuffing box 69, and the second filter assembly is lifted out as a whole through the second lifting rods.

[0034] As a preferred embodiment, the tops of the lifting rod 56 and the second lifting rod 66 are both provided with lifting rings 7. The manufacturer uses special lifting equipment to lift the first and second filter assemblies through the lifting rings for replacement, which is economical, simple and effective.

[0035] As a preferred embodiment, an overflow inlet 551 is provided on one side of the sedimentation tank at the upper end of the overflow interlayer 55, and an overflow outlet 552 is provided on one side of the connecting channel at the lower end, and the precipitated sewage flows from the overflow interlayer into the connecting channel.

[0036] As a preferred embodiment, a box cover 13 is hinged on the box body 1, and the box cover is provided with a plurality of through holes on one side of the second filter area 4. Soil 8 is laid on the box cover on one side of the second filter area. Flowers, plants, vegetables, etc. can be planted in the soil. The box cover is preferably made of a steel plate with a smaller thickness to avoid affecting water absorption.

[0037] As a preferred embodiment, a fiber ball filter material 511 is provided in the sedimentation tank 51 to absorb suspended matter in the sedimentation tank.

[0038] As a preferred embodiment, the packing box contains, from bottom to top, an anthracite packing layer 61, a denitrification and phosphorus removal packing layer 62, a garnet packing layer 63, a ceramsite packing layer 64 and a quartz sand packing layer 65. The filter materials in this device are all made of low-cost, high-recovery and reusable materials to achieve the purpose of reducing costs.

[0039] As a preferred embodiment, a seepage pipe 67 is fixed on one side wall of the stuffing box 69, and a water outlet is opened on the side wall of the box body 1. The seepage pipe is at the same height and coaxial with the water outlet. The seepage pipe is designed as an integral part of the stuffing box to avoid affecting the lifting in and out of the stuffing box.

[0040] As a preferred embodiment, Figure 2 As shown, it also includes a water outlet pipe 12 and a water reservoir. The seepage pipe 67 is provided with an internal thread. The water outlet pipe 12 passes through the water outlet and is threadedly connected to the seepage pipe 67. It should be noted that when the second filter assembly is hoisted in and out, the water outlet pipe needs to be removed to avoid affecting the hoisting in and out of the stuffing box.

[0041] After installation, the device can be used for a long time. The first filter component and the second filter component inside the device can be taken out as a whole for replacement. The filter material in the component can be reused after treatment. The manufacturer regularly recycles and replaces the filter components in a unified manner through special vehicles.
