Problems solved by technology

[0003] The houses in rural areas of our country are basically self-built houses, which are relatively random and lack a reasonable overall layout plan.
Especially in the hilly areas or mountainous areas in southern my country, there are often exclusive households, and it is difficult to implement large-scale construction of centralized sewage treatment stations or the construction cost is high
[0004] In response to this problem, a series of domestic sewage treatment equipment has appeared on the market, but there are many types and complicated follow-up maintenance. At the same time, most of the equipment needs an external power supply to maintain the operation of the device, but this will increase the burden on farmers.
At present, the commonly used ecological filters mainly rely on the action of earthworms, microorganisms and plants in the soil and fillers to remove pollutants. However, due to the small pores of the soil medium and filler media, they may be enriched in small areas in the filter. A large amount of pollutants cannot make full use of the filter space evenly, resulting in poor homogeneity and difficult to guarantee the quality of effluent water

Embodiment 1

[0039] refer to figure 1 , this embodiment provides a non-powered enhanced treatment device suitable for rural domestic sewage, including a high-level water distribution anaerobic reaction unit, a hydroponic ecological adsorption unit and a multi-layer ecological sand filter disposal unit, the hydroponic ecological adsorption unit includes a The first-level hydroponic ecological adsorption unit 13, the second-level hydroponic enhanced disposal unit 16, the high-level water distribution anaerobic reaction unit, the first-level hydroponic ecological adsorption unit 13, and the second-level hydroponic enhanced disposal unit 16 are sequentially connected through the water distribution unit ,in

[0040] The high-level water distribution anaerobic reaction unit includes an anaerobic reaction pool 2, and a water inlet 1 is arranged above the anaerobic reaction pool 2, and the interior is divided into a number of circuitous (up and down zigzag) reaction zones by vertically staggered w...

Embodiment 2

[0055] This embodiment provides a non-powered enhanced treatment method suitable for rural domestic sewage, which is applied to the non-powered enhanced treatment device described in Example 1, including:

[0056] The domestic sewage enters the anaerobic reaction tank 2 from the water inlet 1, and passes through several reaction zones in a circuitous manner one by one. Under the action of microorganisms on the hanging packing 3, most of the pollutants are removed;

[0057] Enter the primary hydroponic ecological adsorption unit 13 through the 1# water guide pipe 6 and the 1# water distribution pipe 8 to realize the process of hanging water and enriching oxygen, and under the action of the plants in the pool I, realize the removal of nitrogen and phosphorus; after passing through the floating ball filling area 9 Finally, under the action of biofilm on its surface, pollutants are further removed;

[0058] Then enter the secondary hydroponic strengthening disposal unit 16 through...

Embodiment 3

[0061] The non-powered enhanced treatment device applicable to rural domestic sewage in Example 1 is installed near the homes of rural residents according to its specific implementation method, and accepts domestic sewage from residents. The domestic sewage COD of this household is 300mg / L, and the ammonia nitrogen concentration is 75.21mg / L L, the total phosphorus concentration is 7.8mg / L.

[0062] The domestic sewage enters the anaerobic reaction tank 2 from the water inlet 1, and passes through 3 reaction zones one by one, and under the action of microorganisms on the hanging filler 3, most of the pollutants are removed. The water distribution pipe 8 enters the first-level hydroponic ecological adsorption unit 13, and removes nitrogen and phosphorus under the action of the 1# plant 7. After passing through the floating ball filling area 9, through the action of the biofilm, the 2# aqueduct 14 and the 2# The water distribution pipe 19 transports the treated waste water to th...

Abstract

The invention discloses a non-powered enhanced treatment device and method suitable for rural domestic sewage, which includes a high-level water distribution anaerobic reaction unit, a hydroponic ecological adsorption unit and a multi-layer ecological sand filter disposal unit, the hydroponic ecological The adsorption unit includes a first-level hydroponic ecological adsorption unit and a second-level hydroponic enhanced disposal unit. Connected in sequence, the water distribution unit is a "branch-shaped" water distributor. Under the action of the water level difference, the water distribution is carried out without power, and the hanging water is formed to further realize the power-free oxygen enrichment. The invention fully considers the terrain characteristics of hilly areas and mountainous areas, and combines the measures of combining multiple reaction zones and water phase reactions to realize the treatment of sewage.

Description

technical field [0001] The invention belongs to the technical category of rural domestic sewage treatment, and in particular relates to a device and method suitable for non-power intensive treatment of rural domestic sewage. Background technique [0002] Rural domestic sewage has become an important object of water pollution prevention and control in my country. However, rural domestic sewage has small water volume, scattered discharge, and complex water quality. Due to the different levels of development, terrain and climate, and personal habits of various rural areas in my country, the amount and quality of rural domestic sewage vary from place to place, but it contains elements such as COD, nitrogen, and phosphorus, which are highly biochemical. Domestic sewage often rarely contains harmful substances such as heavy metal elements, which is conducive to the use of biological treatment technology. [0003] The houses in rural areas of our country are basically self-built ho...
