Description
Technical field
The invention belongs to environmental protection technical field, be specifically related to a kind of improvement method of urban serious rice-nutrient water body.
Background technology
The eutrophication of urban water-body is the ubiquity environmental problem of puzzlement countries in the world, and only the financial loss that causes every year in China is just hundreds of millions of.How administering the eutrophication of water body, is the difficult problem that urgent need will solve in the current environment science.Traditional eutrophication control means are divided into two big classes usually, and a class is the engineering means, but it is only applicable to the end treatment of point source sewage mostly, and cost height, technical difficulty greatly, easily cause secondary pollution; Another kind of is the biotechnology means, though its cost is lower, but it is that these waterplant are after having absorbed the eutrophication material in the water body that a fatal weakness is arranged, if in time do not shift or utilize, nutritive substance finally can turn back to again in the original water body, can not fundamentally solve the problem of water nutrition material surplus.And it should be noted that, the plant that some durability against pollutions are strong, it often also is growth and breeding ratio kind faster, if can not be effectively controlled, very likely cause serious biotic intrusion, threaten the ecological safety in indivedual water bodys even whole basin, the Herba Eichhorniae that present China overflows in many areas is exactly a typical case.
Should see, utilize plant to absorb the important directions that the water nutrition material should be future development, but the key of problem is the recycling problem that how to solve plant.In addition, present most of urban water-bodies are except that certain landscape function, and basically without any the production function, China, especially urbanized area that this is quite nervous in the soil are the huge waste of resource.For this reason, the present invention proposes to utilize the city eutrophication water to cultivate the ornamental plant of high added value, plays both purifying water bodies, and the double effects of producing green plants is arranged.
Summary of the invention
Fa Ming purpose is not to propose a kind of existing good regulation effect, has the hydroponic plant that utilizes of high ecological safety to administer the method for urban serious rice-nutrient water body again.
The hydroponic plant that utilizes that the present invention proposes is administered the method for urban serious rice-nutrient water body, and its key is to select the suitable hydroponic plant and the planting type of hydroponic plant.The present invention is through a large amount of investigations and test, screen two kinds and can be used as the hydroponic plant of administering urban serious rice-nutrient water body, i.e. finger citron philodendron (Philodendron Xanadn is commonly called as the cherub) and philodendron (Philodendron selloum is commonly called as the spring plumage).The mode of aquaculture floating bed is adopted in cultivation.
Process of the test of the present invention is as follows:
By literature survey and market study, 21 kind of plant such as initial option Chunlan, jacinthe, Cyclamen persicum are as research object.Utilize eutrophic water that the plant of drafting is cultivated, cultivating method is to adopt traditional bubble to mould the floating bed method.The plant height of periodic logging plant and the number of blade, the survival of making plant and growing state.Go out 12 kinds of temperature and the adaptable plants of eutrophy water quality with this preliminary screening: jacinthe, Cyclamen persicum, Muscari botryoides, pocket coconut, finger citron philodendron, black beauty, common calla, evergreen, close fruit taro, ivy, philodendron, milk spots green pepper grass
Take all factors into consideration durability against pollution, growing state, to after the factors such as the complexity of the resistance of high and low temperature, cultivation and market outlook, select black beauty (Aglaonema comutatumcv. ' Sanpema '), finger citron philodendron and philodendron three kind of plant and do further test.Selected at last finger citron philodendron and philodendron are used plant as improvement.
1. durability against pollution research
The outer natural environmental condition of simulating chamber, preparation eutrophy concentration of wastewater are respectively 100%, 75%, 50%, 25% and five groups of concentration gradients of clear water.Refresh the water periodically, it is constant substantially to keep respectively organizing concentration.Write down the growing state of every strain plant every day, the periodic measurement plant height is to determine the suitable growth concentration of these plants under differing temps and illumination condition.
Experiment shows: the growing state of philodendron in indoor environment is undesirable, and a strain death is respectively arranged in the cylinder of 100% and 75% concentration, and another strain is also grown not good.Though do not occur dead phenomenon in the cylinder of other three concentration, upgrowth situation is not good.The equal well-grown of philodendron in the simulating chamber external environment, the plant in each concentration all grows young leaves, does not show ill symptoms.Philodendron is grown in the environment of the many illumination of high temperature better, and can adapt to the sanitary sewage environment of 100% concentration.
Finger citron philodendron has 6 strain death in indoor environment, this wherein has the improper reason of planting patterns.In the plant that survives, have only the 3 strains growth in the cylinder of 100% concentration best, the plant in all the other cylinders all grows not good.Finger citron philodendron in the simulating chamber external environment is all grown vigorous, and the plant in each cylinder all has young leaves to grow, and particularly in the cylinder of 100% concentration, plant is especially in great numbers after the off-test, the coring prosperity.Finger citron philodendron enters into an eutrophic water body just, and the bad proterties that shows is more obvious, needs for some time to adapt to new environment, waits until after the adaptive phase that finger citron philodendron can be grown well.
2. detergent power research
According to its requirement to illumination, every kind of plant is provided with 5 repetitions, establishes the blank group simultaneously, is used to eliminate the influence of the self-purification of sewage to experiment own.Total nitrogen, total phosphorus and CODcr concentration in the periodic measurement glass jar, up to this three pollutants density loss till the limit of determination.
Weighing plant weight when the experiment starting and ending is used for analyzing plant to the net absorption of nutritive substance and the increment of plant in addition.Filter out purification and the good plant of growth result with this.The net absorption of plant is by formula:
Wherein c1, c0 are respectively to absorb and reach
Total nitrogen, total phosphorus and the COD content of experimental group and control group during to balance, V is the volume for the body that tries the water, and t is the fate that reaches absorption equilibrium, and m0 is the weight of plant.
The result shows: finger citron philodendron, philodendron have absorption preferably to nitrogen phosphorus in the water body, and the COD of its place water body also descends to some extent.
3. novel floating bed design and open-air pilot scale
By studying existing floating bed, analyze its weak point, design novel floating bed on this basis, its model is made up of three parts, housing, crosspiece and clamp.Material is wood or light plastic, and the three has buoyancy, can guarantee that plant floats on the surface, and sees accompanying drawing 4 for details.
The target plant that filters out is used designed floating bed carry out open-air pilot scale in the Ji Pulu river, the growing state of routine observation plant and the service condition of floating bed are with this feasibility and novel floating bed Application feasibility of coming the evaluating target plant to promote in the eutrophication water of city.
The result shows: floating bed is functional, the phenomenon that lodges does not appear in plant, and upgrowth situation is good and target plant that filtered out can be grown in natural eutrophic water body under natural surroundings preferably, but has also proved that designed ground floating bed has application and promotional value preferably simultaneously.
Therefore: available novel floating bed is planted in full green suede of Buddha's hand and philodendron in the small waters such as sub-district, park, plant grows up after for some time, it is regained and branch's breeding, a part continues plantation, another part puts goods on the market: can be used as the potted plant or hydroponic plant of household, outdoor scene plants etc. produce economic benefits with this.

Embodiment
, as carrying agent above two kind of plant are planted in the eutrophic water body in city with aquaculture floating bed.Aquaculture floating bed is made up of three parts: housing, crosspiece and clamp, form frame-type, and material is wood or light plastic, the three has buoyancy, can guarantee that plant floats on the surface, and sees accompanying drawing 4 for details.There is opening at the two ends of crosspiece, mainly are the abilities that has flexible when being stuck on the housing.On a horizontal frame of fixed, the quantity that can regulate crosspiece flexibly, the density of regulating plant then.Plant is fixed on the crosspiece limit with plastic sheet by clamp, and the both sides of each strain plant are by the fixing plant of clamp.Along with plant grows up, can regulate the distance between the clamp.Simultaneously, because the handiness of clamp also is one of mode of regulating plant density.The synoptic diagram of model is seen Fig. 5.
The not only high temperature resistant but also anti-high-pollution load of finger citron philodendron, growth is rapid, the coring prosperity, and be the perennial evergreen plant, propagation by division is easy to large-scale cultivation.It should be noted that when cultivation to require its stem to surface fully, otherwise can be rotten and dead by immersion, must strict attention this point when water planting.
Philodendron has the same advantage of finger citron philodendron, and does not need to keep stem to surface fully, and its blade is big, and growth is rapid, and palpus shape root is flourishing, but propagation by division.Therefore be a kind of for good resistant, the soil pick-up promoted the use of and ornamental plant with high added value.
Finger citron philodendron, philodendron are respectively 300.4mg/ (dkg), 243.9mg/ (dkg) to the COD removal amount.The prosperity of finger citron philodendron coring can be attached growth of microorganisms, and degradation of organic substances provides the place, and COD is had good effect of removing.The philodendron coring is not as the finger citron philodendron prosperity, so slightly poorer than finger citron philodendron to the removal effect of COD.From per five days COD removal amount: philodendron promptly reaches maximum in the removal amount of test after five days, finger citron philodendron reaches maximum (see figure 1) in the removal amount of test after 20 days, this is because self-purification of waters causes the reduction of COD concentration, and the absolute magnitude of its removal is also reduced.
Finger citron philodendron, philodendron are respectively 75.5mg/ (dkg), 57.57mg/ (dkg) to the T-N removal amount.From per five days T-N removal amount: finger citron philodendron and philodendron just reach maximum (see figure 2) in test the first five day to the removal amount of T-N.Plant absorbing adds self-purification of waters, makes that the T-N density loss in the water body is very fast, thereby the absolute absorption amount of plant is also reduced.
Finger citron philodendron, philodendron are respectively 10.3mg/ (dkg), 10.6mg/ (dkg) to the T-P removal amount.From per five days T-P removal amount: finger citron philodendron and philodendron are all keeping higher absorbed dose (see figure 3) in 25 days after test, this is also relatively poor relevant to the self-purification capacity of phosphorus with water body.
Utilize the floating bed soilless planting method; can produce direct economic and social benefit in the plantation of eutrophic water field surface; the Lu Sheng higher plant of the dry matter production potentiality that tool is bigger again (comparing with floating plant) with the submerged plant in the waterplant; the results plant; when beautifying the waters view; absorption and adsorption by root system of plant; remove the N in the water body; the P element; turn waste into wealth with realization; turn harm into good; purify water; the protection water environment; and can make water body produce benign cycle; the imagination of sustainable performance waters function is not only feasible, and can obtain good effect, thereby provides scientific basis for foundation utilizes floating bed terrestrial plant purifying eutrophic waters.
