Embodiment 1

[0030] The present invention is a device for domestic sewage treatment system in southern rural areas, which is characterized in that the device includes system one and system two, and system one consists of water inlet cloth pipe 1, upper gravel layer 2, river sand layer 3, and waterproof non-woven fabric 4 , lower gravel layer 5, anti-blocking sump 6 and wetland plants A17. The water inlet cloth pipe 1 is located above the upper gravel layer 2, the river sand layer 3 is located between the upper gravel layer 2 and the waterproof non-woven fabric 4, the lower gravel layer 2 and the anti-blocking sump 6 are located below the waterproof non-woven fabric 4, and the anti-blocking The lower gravel layer 2 is arranged around the sump 6, wetland plants A17 are planted on the river sand layer 3, the system 1 outlet pipe 7 is connected between the system 1 and the system 2, and the downflow inlet pipe 11 and the upflow inlet pipe are respectively connected 12. System 2 consists of upp...

Embodiment 2

[0033] Length×width×height of system one: 0.5m×0.5m×0.6m, both systems one and two belong to vertical subsurface flow constructed wetlands, and the flow direction of water flow is downward, and the water inlet distribution pipe also includes the main water distribution pipe 22 And the distribution water pipe 23 is in the shape of "Feng". There is no water distribution hole on the main water distribution pipe 22. There are 4 distribution water pipes 23 with 5mm water distribution holes evenly distributed. The water distribution pipe is higher than the upper gravel layer. The height of 2 is 3cm, and the particle diameter of described upper gravel layer 2 and lower gravel layer 5 is 2cm, laying thickness is 5cm, and described river sand layer 3 particle diameter is 2mm, and filling thickness is 50cm.

[0034] The anti-blocking sump 6 is a hollow structure, its height is consistent with the thickness of the lower gravel layer and three sides are also provided with water accumulatio...

Embodiment 3

[0041] The length×width×height of system one: 0.5m×0.5m×0.6m, the system one and the system both belong to the vertical subsurface flow constructed wetland, and the flow direction of the water flow is downflow, and the water inlet distribution pipe also includes the main water distribution pipe 22 and The branch distribution water pipe 23 is in the shape of "Feng". There is no water distribution hole on the main water distribution pipe 22. There are 4 branch distribution water pipes 23 with 5mm water distribution holes evenly distributed. The water inlet distribution pipe is higher than the upper gravel layer 2 The height is 3cm, the particle size of the upper gravel layer 2 and the lower layer of gravel layer 5 is 2cm, the laying thickness is 5cm, the particle size of the river sand layer 3 is 2mm, and the filling thickness is 50cm.

Abstract

The invention relates to an apparatus of a treatment system for southern rural domestic sewage and a method used by the same. The apparatus comprises a system I and a system II; the system I comprises an influent distribution pipe, an upper gravel layer, a river sand layer, a waterproof non-woven fabric, a lower gravel layer, an anti-blocking water-collecting groove and a wetland plant A; the system II comprises an upper gravel layer, a system II river sand layer, a crushed rock layer, a lower gravel layer, a downstream effluent pipe, an upstream effluent pipe and a wetland plant B; detailed structure and method are described in the specification. The apparatus provided in the invention is designed based on the characteristics of domestic water quality and sewage discharge in southern rural areas, has simple process requirements, is convenient to operate and manage, does not need external electric power facilities, produces a good effect on treatment of domestic sewage and is suitablefor popularization and application in southern rural areas.

Description

technical field [0001] The invention relates to domestic sewage treatment in the aspect of environmental protection, belongs to the field of environmental engineering, and particularly relates to a method and a system for treating domestic sewage of small households in southern rural areas by using a compound artificial wetland. Background technique [0002] With the rapid development of my country's rural economy, especially in southern rural areas, domestic sewage due to changes in daily life has become one of the main reasons for the continuous deterioration of rural water environment. Survey reports show that more than 90% of the villages in most areas have no drainage ditches and sewage treatment systems, domestic sewage is spilled everywhere, rivers near residents are polluted, groundwater is also seriously threatened, and the domestic water use of rural residents is endangered. The discharge of domestic sewage in rural areas of our country continues to increase, and t...
