Abstract
A constructed wetland sewage purification system belongs to the water treatment technical field and comprises a subsurface constructed wetland; the subsurface constructed wetland comprises a wetland bed and aquatic plants planted on the wetland bed; the wetland bed has a three-layer structure and sequentially comprises a gravel layer, a mixture layer and a soil layer from bottom to top; and the mixture layer is composed of lime stone, waste steel slag and furnace slag and soil. The utility model utilizes the soil-plant-microorganism composite ecosystem to purify sewage; compared with other sewage treatment technologies, the constructed wetland sewage purification system has subsurface water flow, good heat preservation and ensures the treatment effect to be less susceptible to weather; the capital expenditure is low and the sewage purification system is easy for maintenance and management; and the aquatic plants not only have good landscape effect, but also have edibleness, medical value and knitting value.
Description
Technical field
The utility model belongs to water-treatment technology field, relates to a kind of artificial swamp sewage purification system.
Background technology
At present, municipal effluent is the important source of pollution of water pollutions such as China's rivers, lake, becomes the factor of restriction China's Economic development and social sustainable development gradually.Various water pollution incidents have had a strong impact on people's production, life, and it is very urgent to strengthen municipal sewage treatment.
In addition, along with the continuous quickening of urbanization process, population in small towns is more and more concentrated, and sanitary sewage does not add handles arbitrarily discharging, and long-run development is gone down to destroy ecology, influenced agriculture production.And reality is, the construction of sewage work and maintenance cost height, head and shoulders above the ability to bear in small towns.
Summary of the invention
The purpose of this utility model is for a kind of artificial swamp sewage purification system is provided.
For realizing this purpose, the utility model has been taked following technical scheme: a kind of artificial swamp sewage purification system, comprise underflow type artificial wet land, this artificial swamp comprises wetland bed and is planted in the waterplant of wetland bed top, described wetland bed be three-decker, be followed successively by gravel bed from bottom to top, by the blending layer that Wingdale, waste steel slag waste slag and soil constitute, pedosphere.
Described waterplant is reed, Scirpus tabernaemontani, Canna generalis Bailey, wild rice stem or lotus root.
Described sewage purification system also comprises settling tank and oxidation pond, settling tank, oxidation pond link to each other successively with underflow type artificial wet land, the water inlet of settling tank is provided with grid, be provided with lift pump between settling tank and the oxidation pond, the oxidation pond water outlet feeds the blending layer of underflow type artificial wet land, and the gravel bed of underflow type artificial wet land is provided with water outlet.
Sewage flows in the settling tank through grid earlier, remove the floating matter postprecipitation about 1 day, supernatant liquor is squeezed in the oxidation pond by lift pump, flows into artificial swamp after aeration is handled, and utilizes the Trinitarian complex ecosystem of soil-plant-microorganism that sewage is carried out purifying treatment:
Sewage enters wetland bed from the middle layer, flow out from the bottom water outlet at last; The role that flourishing root system of plant and wetland bed body have been taken on biofilm carrier also has good crown_interception simultaneously.Effluent stream is removed heavy metal through wetland bed by effects such as precipitation, filtration, complexing, absorption; Some zone is in anoxic condition in wetland bed, and has been in oxygen condition around the root system of plant, can rely on the nitrification and denitrification effect of bacterium for the bacterium colony existence of different population, can reach good denitrification effect; Phosphor-removing effect is finished in actings in conjunction such as the holding back of the absorption by plant, the accumulation of microorganism and bed body, absorption.
The utility model is compared with other sewage disposal technologies, and its current flow under the surface, good heat preservation performance, and treatment effect is subjected to weather effect less.In addition, capital cost of the present utility model is cheap, handles structures and forms by various natural ecological systems or through simple reconstruction, does not have complicated mechanical equipment, is easy to running maintenance and management, and working cost is also cheaper.The packing material that wetland bed each layer selected for use also can be gathered materials on the spot, and has both made some industry or agricultural wastes obtain recycling, has also saved investment cost simultaneously.Simultaneously, various waterplant not only have good landscape effect, also have utility values such as edible, medicinal, braiding.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
A kind of artificial swamp sewage purification system as shown in Figure 1, comprises the settling tank 1, the oxidation pond underflow type artificial wet land that link to each other successively, is provided with lift pump 3 between settling tank 1 and the oxidation pond 4, and the water inlet of settling tank 1 is provided with grid 2, can remove the floating matter in the decontaminated water.Sewage enters in the settling tank 1 precipitation after 1 day through grid 2, and utilize lift pump 3 to squeeze into to carry out aeration in the oxidation pond 4 to handle, and then flow into underflow type artificial wet land and do further to purify, but through just qualified discharge after 5～20 days the purification.
Underflow type artificial wet land comprises wetland bed and is planted in the waterplant 5 of wetland bed top, described wetland bed be three-decker, be followed successively by gravel bed (bottom) 8 from bottom to top, the blending layer (middle layer) 7 that Wingdale, waste steel slag, waste slag and soil constitute, pedosphere (top layer) 6; Described waterplant 5 is reed, Scirpus tabernaemontani, Canna generalis Bailey, wild rice stem or lotus root.The water outlet of oxidation pond 4 feeds the blending layer (middle layer) 7 of underflow type artificial wet land, and the gravel bed of underflow type artificial wet land (bottom) 8 is provided with water outlet 9, and sewage flows into artificial swamp after aeration is handled, be seeped into bottom 8 then, discharges from water outlet 9 at last.
Top layer 6 soil can be selected calcareous composite soil for use, help improving dephosphorization effect.Middle layer 7 usefulness particle diameters are in Wingdale, waste steel slag waste slag and the soil blending of 5～10mm, because use Wingdale to be unfavorable for plant-growth separately, the waste steel slag waste slag then can go out the phosphoric in the decontaminated water.Bottom 8 is selected gravels such as pebbles for use.Waterplant 5 well developed root systems such as reed, Scirpus tabernaemontani, Canna generalis Bailey, wild rice stem, lotus root, cauline leaf are dense, and resistant, cold tolerance are stronger, can beautify the environment, create economic benefit when purifying water.
