Problems solved by technology

On the one hand, part of the untreated domestic sewage evaporates naturally, and part of it flows into the road side ditch along the low-lying places and is discharged directly to the river body, causing serious pollution to the water quality of the river body; on the other hand, referring to urban sewage treatment plants, building small sewage treatment plants system, but due to the high operating costs and the need for professionals to be responsible for the operation and management, the vast majority of sewage treatment stations have stagnated after completion

Embodiment Construction

[0009] The specific content of the present invention will be described in detail in conjunction with the accompanying drawings. An unpowered ecological sewage treatment system, the domestic sewage is collected into the water distribution tank after passing through the urban household septic tank, and then evenly enters the first-level horizontal subsurface flow artificial wetland 1 through the perforated flower wall on one side of the water distribution tank, and the first-level horizontal underflow artificial wetland 1 Homogeneous gravel 2 with a particle size of 50-70 mm and a thickness of 1.2 m is used as filler, reed 3 is used for planting plants, and a water collection system is provided at the bottom of the homogeneous gravel 2. The water collection system adopts perforated pipe 4 and perforated pipe 4. The water outlet of the water collection well 5 communicates with the water collection well 5, and the side opposite to the opening of the water collection well 5 is provi...

Abstract

The invention discloses a powerless biological sewage treatment system. Domestic sewage is gathered and fed into a constructed wetland water distribution tank from urban household septic-tanks, is subsequently uniformly fed into a first-stage horizontal subsurface flow wetland through a punched flower wall on one side of the water distribution tank, is further fed into a second-stage horizontal subsurface flow wetland through a water collecting system at the bottom of the first-stage horizontal subsurface flow wetland and a water collecting well, and is subsequently fed into a pit-pond or a river from the water collecting system at the bottom of the second-stage horizontal subsurface flow wetland; typha orientalis or phragmites commiunis can be planted on slopes which are 0.2-1.0m in depth at the pit-pond or the river; artificial ecological floating islands are arranged at the water depth of 1.5-2.5m; and aquatic plants are planted on the ecological floating islands. Existing pit-ponds and rivers in rural areas are utilized, so that the construction cost can be lowered to a very large extent; no special operation management is needed, only cleaning at regular time is needed, the maintenance expense and the equipment operation expense can be reduced, the whole system is good in greenery landscape effect, and the idea of constructing beautify village homes can be met.

Description

technical field [0001] The invention belongs to the technical field of urban domestic sewage treatment systems, and in particular relates to an unpowered ecological sewage treatment system. Background technique [0002] With the improvement of rural living standards in our country, the amount of sewage discharged in rural areas is also increasing day by day. However, due to the shortage of sewage treatment funds at the village level and the weak awareness of rural water environment protection, the lack of effective management and treatment capabilities, there is basically no complete domestic sewage. Collection systems and treatment facilities. The random discharge of untreated domestic sewage seriously pollutes the rural ecological environment and directly affects the health of the broad masses of farmers and the economic development of the countryside. On the one hand, part of the untreated domestic sewage evaporates naturally, and part of it flows into the road side ditc...
