Abstract
The invention relates to a constructed wetland plant community for watercourse in-situ remediation. The constructed wetland plant community comprises emerging plants, floating plants and sunken plants, wherein the emerging plants comprise acorus gramineus and ludwigia peploides; the floating plants comprise nymphoides peltatum and marsilea quadrifolia; the sunken plants comprise potamogeton malaianus and vallisneria spiralis. The invention provides the constructed wetland plant community which is large in ammonia nitrogen, total nitrogen and phosphate removal rate, and application of the constructed wetland plant community, so that significance on improvement of river water quality, water area environment and physical health of people are realized.
Description
Technical field
The present invention relates to a kind of constructed wetland plant group for water course in situ reparation and application thereof.
Background technology
Artificial swamp is a kind of Novel sewage eco-treatment technology grown up late 1970s, have construction investment few, operation operation cost low, removal nitrogen phosphorus ability is strong, good purification, has the advantages such as higher treatment effect to containing low concentration heavy metal water.Artificial Wetland Techniques is used widely in municipal effluent second-stage treatment and advanced treatment, improvement river lake eutrophication and heavy metal contamination etc.
Wetland plant is the important component part of artificial swamp, and have vital role to the conversion of pollutent and degraded, it can directly absorb, utilize the nitrogen phosphorus in sewage used as own growth; The material such as enzyme of root system of plant release can direct degradation of contaminant, and degradation speed quickly; Plant can also be adsorbed and enriching heavy metal and some hazardous and noxious substances.There are some researches show, different wetland plants is different to the absorption adsorption effect of pollutent, the enzyme of root system release and rhizospheric microorganism population and quantity difference to some extent, thus affects artificial swamp to pollutant removal.Investigate the effect of dissimilar plant purification polluted-water, the screening maximized constructed wetland plant group of acquisition one group of removal effect, has great importance to the Study and appliance improving artificial wetland treatment efficiency and phytoremediation polluted-water.
Summary of the invention
The object of the invention is to provide one group to the good constructed wetland plant group of water course in situ repairing effect and application thereof.
The technical solution used in the present invention is:
A kind of constructed wetland plant group of repairing for water course in situ, be made up of emergent, floating plant and submerged plant, described emergent is Bilbao Red calamus and the chrysanthemum fire hose, and described floating plant is floating heart and field word duckweed, and described submerged plant is p.malaianus and eel grass.
The cultivated area ratio of described emergent, floating plant and submerged plant is preferably 1:2:1.
The invention still further relates to the application of described constructed wetland plant group in water course in situ is repaired.Described plant community is planted in the artificial swamp built, namely can be used for water course in situ reparation.
The invention still further relates to described constructed wetland plant group and improve the application in water environment.Directly planted by described plant community in river course or pond, will be greatly improved water environment.
Beneficial effect of the present invention is mainly reflected in: the invention provides the high constructed wetland plant group of one group of ammonia nitrogen, total nitrogen, removal rate of phosphate and application thereof, to sewage quality of making the life better, improve water environment, to improve people healthy significant.
Embodiment
Below in conjunction with specific embodiment, the present invention is described further, but protection scope of the present invention is not limited in this:
Embodiment 1:
1 materials and methods
1.1 material
1.1.1 water sample material
Water sample is from three rivers: lower husky No. three embankment Hu Tanghe, pioneer river, Xiaoshan, Long Wan rank street, Wenzhou water channel; Water sample entrusts Hangzhou Pu Luosaisi to monitor Science and Technology Ltd.'s monitoring, and former water monitoring result is as shown in table 1:
Table 1: the former water monitoring result of water sample
1.1.2 vegetable material
Choose 3 groups respectively by different emergent, swim to plant the waterplant that emergent, floating plant and submerged plant group thing and submerged plant form and combine, the cultivated area ratio of emergent, floating plant and submerged plant is that (often the cultivated area ratio of identical type plant as Bilbao Red calamus and the chrysanthemum fire hose is 1:1 to 1:2:1 in group in addition, subregion is planted), first group (T1) is: Bilbao Red calamus+chrysanthemum fire hose--floating heart+field word duckweed--p.malaianus+eel grass; Second group (T2) is: power flower+Arundo donax again--spatterdock+frogbit--water caltrop+hydrilla verticillata; 3rd group (T3) is: mullet grass+Scirpus tabernaemontani--sub-iris+floating heart--, and watermifoil+mushroom is careless.
Internal diameter is 980cm × 760cm × 670cm plastic crate 30.
1.2 method
3 the sanitary sewage water samples chosen: the pioneer river of Xiaoshan, Zhejiang, Wenzhou Long Wan rank street water channel and lower husky No. three embankment Hu Tang rivers.4 process such as contrast and three groups of combinations of plant process are established in the water intaking of each waters respectively, and process except for the control repeats 3 times, and the treatment time is January.The process in the pioneer river of Xiaoshan, Zhejiang is respectively CK1, XT1, XT2, XT3; The process of Long Wan rank street, Wenzhou water channel is respectively CK2, WT1, WT2, WT3; The process in lower husky No. three embankment Hu Tang rivers is respectively CK3, XS1, XS2, XS3.
Often process water intaking 0.4 liter, put into plastic crate.Simulation riverbed planting plants, edge establishes the low bank of earth between fields higher than water surface 10cm, wide 30cm, is transitioned into the soil layer of 30cm from the ridge successively by 50cm gradually, and three groups of plants of design are planted successively by the order of above-mentioned emergent, floating plant and submerged plant.After planting plants process, measure the pH, chemical oxygen demand (COD), five-day BOD, ammonia-nitrogen content, total nitrogen content, phosphate content, permanganate index, basicity, anion surfactant etc. of each process respectively, the results are shown in Table 2 ~ table 4.
2 results and analysis
Table 2: first group of plant water sample detected result
Table 3: second group of plant water sample detected result
Table 4: the 3rd group of plant water sample detected result
By the known three groups of plants in table 2 ~ 4, institute's Testing index in test item is removed all to some extent, but clearance is that ammonia nitrogen, total nitrogen, phosphoric acid salt are substantially about 90% preferably, what clearance was best is first group of plant, ammonia nitrogen, total nitrogen, phosphoric acid salt can reach five class water requirements of surface water substantially, effectively can play process sanitary sewage, improve the effect of water area water-quality.
Claims (4)
