Embodiment 1

[0028] Example 1: Method and device for treating domestic sewage sand and gravel biofilter for a family of three

[0029] The daily domestic water consumption of a family of three is about 75L. According to the amount of domestic sewage produced every day and the saturated capacity of the sand biofilter to treat domestic sewage, the volume of the sump 1 is 30L, and the size is length×width×height= 0.5m×0.2m×0.3m; sand and gravel biofilter 2 size is length×width×height=1.9m×1.0m×0.9m, volume is 1.71m 3 .

[0030] The structure of the device is as figure 1 As shown, the sump 1 and the sand biofilter 2 are connected through the water inlet pipe 3, the inner diameter of the water inlet pipe 3 is 40mm, and the three-type polypropylene pipe (PP-R pipe, product of Shandong Yanggu Shunda Plastic Co., Ltd.) is selected, and the water inlet pipe 3 A sieve 4 is set at the sewage inlet, and the sieve aperture is 2.5 mm. There are three layers of materials in the body of the sand biofil...

Embodiment 2

[0032] Example 2: A family of four domestic sewage sandstone biofilter treatment method and device

[0033] The daily domestic water consumption of a family of four is about 100L, the volume of the sump 1 is selected as 30L, and the size is length × width × height = 0.5m × 0.2m × 0.3m; according to the amount of daily domestic sewage and sand biofiltration The saturated capacity of the pond to treat domestic sewage, the size of the sand and gravel biological filter 2 is length × width × height = 2.1m × 1.2m × 0.9m, and the volume is 2.25m 3 .

[0034] The structure of the device is as described in Example 1, except that the inner diameter of the water inlet pipe 3 is 46 mm, and 5 rows of water pipes 6 are laid in the first cobblestone layer with an inner diameter of 24 mm.

Embodiment 3

[0035] Example 3: The treatment method and device of domestic sewage sand and gravel biofilter for a family of five

[0036] The daily domestic water consumption of a family of five is about 125L. The volume of the sump 1 is designed to be 30L, and the size is length × width × height = 0.5m × 0.2m × 0.3m; The saturated capacity of the pond to treat domestic sewage, the size of the sand and stone biological filter 2 is length × width × height = 2.5m × 1.25m × 0.9m, and the volume is 2.81m 3 , In order to facilitate water discharge, the bottom of the sand and gravel biofilter is designed with a slope of 5 degrees.

[0037] The structure of the device is as described in Example 1, except that the inner diameter of the water inlet pipe 3 is 50 mm, and 6 water distribution pipes 6 with an inner diameter of 26 mm are laid in the first cobblestone layer.

Abstract

The invention relates to an unpowered method and an unpowered device for treating single-family rural domestic sewage. The domestic sewage treatment device mainly comprises a collecting basin and a sand biofilter, when the domestic sewage enters the device from the collecting basin, seeps through the sand biofilter through a water distribution tube, and is discharged through a pipeline after being adsorbed and degraded by the sand biofilter. The method and the device have good effect in domestic sewage treatment, and effluent has chemical oxygen demand (COD) less than 100mg/L and can be used for watering vegetables, flushing the toilet and the like; and the device has low construction cost, only costs about 1,000 yuan for every single family, and can be accepted by farmers easily. The device has small floor area, no power, convenient maintenance and use and long term use without washing; and vegetables can be planted on the device so as to sufficiently utilize space.

Description

technical field [0001] The invention relates to a method and device for treating domestic sewage in single-family rural areas without power, and belongs to the technical field of wastewater treatment. Background technique [0002] The "Eleventh Five-Year Plan" put forward the major historical task of building a new socialist countryside, and clarified the construction goals of "development of production, affluent life, civilized rural style, clean and tidy village appearance, and democratic management". However, with the acceleration of the construction of new countryside, domestic sewage has become a major source of pollution. A large amount of domestic sewage is directly discharged into the gutter without treatment, and then seeps into the groundwater layer or leads to rivers, causing serious damage to the surrounding environment of the countryside and directly threatening Residents are in good health. According to estimates, the rural areas of the country produce more th...
