Technical field
The utility model relates to technical field of sewage, particularly relates to a kind of novel unpowered artificial marsh sewage treatment system
Background technology
In side slope, soil conservation such as road both sides and riverbank or lakeside ground, often occur because of rainwater cross flow under the situation that does not have pumping equipment, silt underwashing, cause soil erosion, the problem of water body muddiness, the main means of controlling soil erosion at present are to need soil conservation ground to build artificial marsh sewage treatment system at these, carry out the collection of rainwater and sewage, handle and utilization, the artificial swamp technology of existing a lot of types, surface low type wetland for example, horizontal flow pattern wetland and vertical flow pattern wetland, but processing efficiency is relatively low, and the artificial swamp many places are in having inconvenient traffic, incomplete remote mountain areas of Infrastructure and rural area, some region even existence can't guarantee the problem to the power supply of Sewage treatment systems.
The utility model content
The purpose of this utility model provides a kind of making full use of the natural resources, and is applicable to the novel unpowered artificial marsh sewage treatment system in remote mountain areas and rural area.
The technical solution of the utility model is:
Novel unpowered artificial marsh sewage treatment system, it is characterized in that comprising grating tank, equalizing tank, vertical current constructed wetland, horizontal flow artificial wetland and the water outlet adjusting well of the connection of order pipeline, between described equalizing tank and the vertical current constructed wetland difference of altitude is arranged, between described vertical current constructed wetland and the horizontal flow artificial wetland difference of altitude is arranged.
Further, grating tank is connected with equalizing tank by pipeline, equalizing tank is connected with the one-level subsurface constructed wetland by pipeline, sewage enters vertical current constructed wetland from the water outlet of equalizing tank by pipeline self, the water outlet gravity flow of vertical current constructed wetland enters horizontal flow artificial wetland, and described horizontal flow artificial wetland is regulated well with water outlet and is communicated with.
Further, vertical current constructed wetland comprises organic dielectric layer and blending agent layer from the top down, and water distribution pipe is distributed in the top of described blending agent layer according to a determining deviation, and header is distributed in the bottom of vertical current constructed wetland according to a determining deviation.
Water distribution pipe is distributed in 0.2m place under the upper surface of described blending agent layer.
The header of described vertical current constructed wetland is connected with the water distributor of horizontal flow artificial wetland.
Further, the order of horizontal flow artificial wetland comprises water distribution gabion section, the blending agent section and the gabion section of catchmenting, water distributor and header distribute respectively in the water distribution gabion section and the gabion section of catchmenting, water distributor and header periphery are piled up Wingdale and are constituted the water distribution gabion section and the gabion section of catchmenting, and the water distributor of described horizontal flow artificial wetland is connected with the header of vertical current constructed wetland.
Novel unpowered artificial marsh sewage treatment system efficient height of the present utility model, denitrification effect is good, be difficult for taking place short flow phenomenon, and the fortune of this system need not to answer electrical installation, be equivalent to the zero run expense, can solve the sewage handling problem in the rural area that is positioned at the remote mountain areas smoothly.

Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
Of the present utility model novel unpowered artificial marsh sewage treatment system as shown in Figure 1, comprise grating tank 1, equalizing tank 2, vertical current constructed wetland 3, horizontal flow artificial wetland 4 and water outlet adjusting well 5 that the order pipeline is communicated with, grating tank 1 is connected with equalizing tank 2 by pipeline, equalizing tank 2 is connected with vertical current constructed wetland 3 by pipeline, and vertical current constructed wetland 3 is connected with horizontal flow artificial wetland 4; Between equalizing tank 2 of the present utility model and the vertical current constructed wetland 3 difference of altitude is arranged, between vertical current constructed wetland 3 and the horizontal flow artificial wetland 4 difference of altitude is arranged.
Together artificial grid is set in the grating tank 1 of the present utility model, is used to remove the suspended substance of country sewage; Equalizing tank 2 is used for carrying out the adjusting of water quality and quantity and sewage is carried out preliminary sedimentation owing between equalizing tank 2 and the vertical current constructed wetland 3 difference of altitude is arranged, sewage from the water outlet of equalizing tank 2 by pipeline self to vertical current constructed wetland 3.
Vertical current constructed wetland comprises organic dielectric layer 6 and blending agent layer 7 from the top down, vertical current constructed wetland water distributor 8 roads are distributed in the top of blending agent layer 7 according to a determining deviation, and vertical current constructed wetland header 9 is distributed in the bottom of vertical current constructed wetland 3 according to a determining deviation.In this example, the vertical current constructed wetland water distributor is distributed in 0.2m place under the upper surface of blending agent layer 7, serike such as reed on the organic dielectric layer 6.The sewage that the enters vertical current constructed wetland organic dielectric layer of flowing through from top to bottom, the blending agent layer is by pollutent in medium, reed, the microbiological deterioration water and elements such as N, P.
Further, the order of horizontal flow artificial wetland 4 comprises water distribution gabion section, the blending agent section 10 and the gabion section of catchmenting, difference level distribution person who lives in exile worker's wetland water distributor 11 and horizontal flow artificial wetland header 12 in the water distribution gabion section and the gabion section of catchmenting, the periphery of horizontal flow artificial wetland water distributor 11 and horizontal flow artificial wetland header 12 is piled up Wingdale, constitute water distribution gabion section respectively and the gabion section of catchmenting, vertical current constructed wetland header 9 is connected with horizontal flow artificial wetland water distributor 11.Owing between vertical current constructed wetland 3 and the horizontal flow artificial wetland 4 difference of altitude is arranged, sewage is handled the back by vertical current constructed wetland header 9 by vertical current constructed wetland 3, gravity flow enters horizontal flow artificial wetland water distributor 11, come water distribution uniformity and catchment by pipeline and Wingdale, the sewage sequential flow is through the water distribution gabion, blending agent, gabion catchments, pass through medium, reed, microbiological deterioration pollutants in sewage matter, the combination of vertical current and horizontal flow form is the sewage treating efficiency height not only, and denitrification effect is good, it is on-the-spot to be difficult for taking place short stream, and this system do not have electric installation and uses, and the zero run expense solves the country sewage that is positioned at the mountain area smoothly and handles problems.In this example, the water level of vertical current constructed wetland is by 13 controls of intermediate regulations well.The water level of horizontal flow artificial wetland is regulated well 5 controls by water outlet.
Above-mentionedly only several specific embodiments in the utility model are illustrated; but can not be as protection domain of the present utility model; every equivalence of having done according to the design spirit in the utility model changes or modifies, and all should think to fall into protection domain of the present utility model.
