Summary of the invention
At the deficiency that prior art exists, main purpose of the present invention just provides that a class cost is low, efficient is high, the new plant combination of easy growth, view U.S. and be used for the artificial swamp of purifying domestic sewage.
The release of this new plant combination is human settlement's the place of craving for, and also is the strong countermeasure of environment protection.Can estimate that market outlook are wide, be mainly reflected in following three aspects: 1. during realtor's real estate newly developed, this constructed wetland plant combination of investment configuration immediately can make it beautiful environment not account for a large amount of plot, and house property can rise in value, so demand is big.2. existing artificial swamp faces the demand, particularly sewage work of samll cities and towns that new technology is transformed.3. country begins to administer the rivers and lakes pollution, and this combination kind of staggered band in relevant land and water can play extraordinary effect.At present, along with Chinese economic development, water pollution and water shortage problem are more and more serious, comply with this situation, and various sewage disposal technologies comprise that constructed wetland waste water treatment technology has obtained wideling popularize.Applying in the process of artificial swamp, problems such as for example plant species screening and configuration, engineering surface harden, plant harvesting management many problem demanding prompt solutions appearred.
The new plant configuration of the artificial swamp that is used for purifying domestic sewage of the present invention is compared with the traditional plant combination, this combination tool highly diverse, high-survival rate, anti-pollution, purification well, the characteristics of wide, the microbial population of deriving of view U.S., suitable natural disposition.Can handle for all kinds of purifying domestic sewages in city.The constructed wetland plant that these are new, mainly from the combinations of plant of the staggered band in aquatic or land and water of the spontaneous growth of long-term introduction and acclimatization, it is the plant of tool view and efficient cleaning action, it also can be connected with matrix, plant, the microorganism of existing various artificial swamp types, and breeds easily and manage.
The constructed wetland plant layoutprocedure that is used for purifying domestic sewage of the present invention is described in detail as follows:
1, technical characterictic
1), the main kind of new plant combination
Plants (past is not used for artificial swamp) such as the Job's tears of process screening domestication, water ghost any of several broadleaf plants, Bai Jianghua, yellow luxuriant venezuela heliconia, folded fringe nutgrass flatsedge, chrysanthemum Lin.Here domestication refers to plant is placed the artificial swamp contaminate environment, makes it adapt to contaminate environment gradually, and unconformable plant is dead in the domestication process.Plant after the domestication reconfigures and has promptly formed the new plant combination.
2), the configuration of combinations of plant
But these plant arbitrary combination plantations needn't only be made up of a kind of plant as past constructed wetland plant bed.
Can be used on any type of artificial swamp matrix of usefulness, planting at present.
2, advantage
1), purify waste water, optimizes the environment by artificial swamp;
2), long service life, but life-time service, cost is low, easy construction is easy to plantation and safeguards;
3), good purification, can be used for present most sanitary sewage disposal;
4), can on any artificial swamp matrix of operation at present, plant;
5), system is subjected to weather effect less, and is and ordorless, the fly mosquito is less etc.In environment purification, can beautify the environment.
