A kind of sun power microkinetic is from pouring dry type ecological floating island
Technical field
The utility model relates to environmental engineering and water technology, aims to provide a kind of sun power microkinetic of beautifying for eutrophication water restoration of the ecosystem and garden landscape water body from pouring dry type ecological floating island.
Background technology
In recent years, along with people are more and more concerned about living environment problem, the quality of physical environment, the particularly water surrounding of periphery and natural landscape situation waterborne are also more and more paid attention to.Along with urban afforestation beautifies the fast development of work, landscape water body is on the increase, due to fresh insufficient water sources, some municipal lakes, river or water quality of landscape water constantly worsen, water body presents eutrophication, causes algae excess growth, fish kill, havoc water ecological environment.
Ecological floating island technology is to utilize the principle of biological pollution treatment, allows plant by absorption of nutrient ingredients superfluous in water, realizes the purification of water quality, provides the space that is applicable to other biological life, to repair or to rebuild aquatic ecosystem simultaneously.
As a kind of novel environmental protection technology, artificial ecological floating island appears at the 70's of 20th century the earliest, is researched and developed by German Besterman company.By building a stage apparatus that floats on the water surface, plant multiple emergent, utilize growing process the absorption of Water, phosphorus etc. to be reached to the object purifying water.This technology can purify water on the one hand, for birds provide home, can improve on the other hand fish egg reproduction environment and increase fisherman's income.
Thereafter ecological floating island has experienced again large several times development, the application of especially Japanese ecological floating island technology, strengthened root system of plant to beneficial microorganism growth-promoting functions in water, the range of application of also greatly having widened ecological floating island, has promoted the purifying water effect of ecological floating island.The eighties in 20th century, Japan starts the extensive this technology of introducing, and self water body is repaired, and wherein the Biwa Lake of Japan just has maximum at that time artificial floating island.In lake, the world conference of nineteen ninety-five, artificial article floating island starts by universally acknowledged as a kind of technology of administering sewage subsequently, and Korea S, Canada, Britain etc. start to pay close attention to and study this technology in succession.
Compared with traditional water pollution control technology, artificial article floating island technology exists several obvious advantages: carry out original position reparation at pollution scene, be not subject to the restriction of water depth, transparence and Eutrophic Extent, be particularly suitable for the improvement of river course, lake eutrophication; Expense is cheap, and with respect to traditional pollution treatment technology, this technology can be saved more than 50% construction cost, and maintenance cost is cheap, also can improve view.
Wherein, ecological floating island to the main protection function of water surrounding be embodied in following some:
1, purification of water quality.On dependence chinampa, planting growing plants absorbs the nutritive ingredient such as nitrogen, phosphorus in water body and relies on those to be attached to the microbially decontaminate water body of plant root;
2, create the biological space of living.The place that utilizes the bridging effect on chinampa to provide breeding to lay eggs to fish etc., meanwhile, chinampa also can provide the space of perching to birds;
3, improve view.The various plants and flowers of planting on chinampa can obviously be improved water scenery, by reasonably combined, more can build special garden landscape waterborne;
4, wave absorbing revetment.Ecological floating island can form provide protection, the impact of subduing wave by opposite bank base.
Therefore, ecological floating island technology is gushed in reservoir, lakes and marhshes, river, or has the closed water areas such as the pond of view requirement to obtain development and application widely.
Existing ecological floating island product in China market at present, these products, generally using plastic foam as chinampa carrier, are above opened some holes, by plant " plantation " the inside.These products mainly contain following shortcoming in actual applications:
(1) lack power set, limited to contacting of water, cleaning action can not be given full play to;
(2) only utilize the effect of waterplant Root Absorption, can only reduce nitrogen in water, phosphorus, special microbe carrier is not set, its microbial film charge capacity is limited, is difficult to reduce organic pollutants content, cuts down COD, BOD etc.;
(3) can not improve oxygen in water concentration, be difficult to promote the self-purification of water body and improve aquatic Fish Survival environment;
(4) suitable kind of plant kind is too single, mainly concentrates on some large-scale emergents, and landscape effect can not get embodying, and the range of application on chinampa is subject to certain restrictions.
In general orientation, ecological floating island is divided into two classes: dry type ecological floating island and wet type ecological floating island.
Dry type ecological floating island refers to the root system of plant of planting on chinampa and does not directly contact the ecological floating island of water body, and does not apply at present at home substantially on dry type chinampa.Wet type ecological floating island refers to the root system of plant of planting on chinampa and directly touches the ecological floating island of water body, and this is the ecological floating island type being most widely used at present.
Domestic ecological floating island is all wet type chinampa at present, to plant various waterplant as main.Although the purifying water effect on wet type chinampa is better, make the landscape effect on chinampa can not get good embodiment because floristics is too single, the decontamination effect improving of plant is also difficult to be improved with replacing with simultaneously, is often the fittings in engineering of water treatment.
Dry type chinampa is because plant does not directly contact with water body, can cultivate large-scale woody, gardening plant, by different combinations of plant, form the good biology such as birds, the fish place of living, also beautified greatly view, but dry type chinampa also exists some problems simultaneously, the one, there is no the purification function of chinampa to water body, the 2nd, need regular manual watering, with the required moisture of supply plant-growth, greatly increase the cost of labor in later stage.General this large-scale dry type chinampa is to be made with concrete or polystyrene material.
Utility model content
