Description
Technical field
The present invention relates to the technology for treating industrial waste water field, especially a kind of plants configuration method that is applied to vertical current-horizontal drowned flow combined artificial wetland.
Background technology
Along with Chinese society rapid development of economy and quickening of urbanization process, cities and towns water imbalance between supply and demand becomes increasingly conspicuous on the one hand, and a large amount of dischargings of flood tide wastewater and sewage make that again resource of water supply is constantly polluted on the other hand, and then water quality environment is constantly worsened.The artificial swamp technology is a kind of ecological sewage treatment technology that grows up the seventies in last century, the ecosystem that utilizes engineering measure simulating nature wetland to build.Artificial swamp mainly contains matrix, plant, microorganism formation, it mainly utilizes the physics, chemistry of system mesostroma-waterplant-microorganism, biological triple synergies, realizes efficient purification to sewage by filtration, absorption, ion-exchange, plant absorbing and the microbiological degradation of matrix.Artificial swamp mainly contains surperficial streaming, vertical streaming, horizontal drowned flow formula, uses more and more widely in conjunction with the combined artificial wetland of several wetland advantages in these several years.In actual applications, China's artificial swamp appliable plant kind is less, and is bad to the decontamination effect improving of trade effluent.The plant that generally is used for sanitary sewage disposal has raupo (Typhs angustifolia), Medulla Junci (Juncuseffuses), Scirpus tabernaemontani (Schoenoplectus lacustris), calamus (Acorus calamus) or the like.These plants are for trade effluent, the higher waste water of heavy metal ion content particularly, and absorption purifying effect is limited, and in actual applications, is the plot plantation of unit with certain kind of plant often, and treatment effect is single, and landscape effect is poor.
Summary of the invention
The technical problem to be solved in the present invention provides that a kind of cost is low, processing efficiency is high, easy growth, the plants configuration method that is applied to vertical current-horizontal drowned flow combined artificial wetland that landscape effect is good.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of plants configuration method that is applied to vertical current-horizontal drowned flow combined artificial wetland, it has landscape effect and wastewater treatment efficiency concurrently, and its gordian technique is that horizontal drowned flow wetland pond plants any one or a few combination of following plant: reed, beauty Jiao, Stenocalyx micheli, Herba pteridis vittatae, Phytolacca acinosa, Li Shi standing grain, cyperus alternifolius, Indian mustard; Any one or a few combination of following plant is planted in the vertical-flow wetland pond: Medulla Junci, Spiked Loosestrife, Sedum alfredii Hance, sky blue penny cress, rye grass, Stenocalyx micheli, Herba pteridis vittatae, Phytolacca acinosa, Li Shi standing grain, cyperus alternifolius, Indian mustard; The quantitative proportion of plantation plant is 1: 1.5～2 in described vertical-flow wetland pond and the horizontal drowned flow wetland pond; After treating vertical current-horizontal drowned flow combined artificial wetland pond retaining, plantation floating plant water lily and/or Herba Eichhorniae on the water surface in vertical-flow wetland pond.
Above-mentioned plants configuration method preferably is applied to the vertical current-horizontal drowned flow combined artificial wetland of following structure: the vertical-flow wetland pond is last, and horizontal drowned flow wetland pond is following, and horizontal drowned flow wetland pond is located at below the ground surface; The matrix in described vertical-flow wetland pond is followed successively by coarse sands layer, artificial mixolimnion, gravel district from top to bottom, and top, vertical-flow wetland pond is provided with water distributor, is provided with dredging flow groove at the bottom of the pond, and dredging flow groove top is porous disc, and the dredging flow groove bottom is a waterproof layer; Both sides, described horizontal drowned flow wetland pond are the gravel district, the centre is the matrix district, the matrix district is followed successively by coarse sands layer, artificial mixolimnion, coarse sands layer from top to bottom, the diaphragm that is provided with is distinguished matrix and is slit into snakelike water stream channel, the bottom, pond is provided with dredging flow groove, the dredging flow groove bottom land is provided with waterproof layer, and the water outlet position that dredging flow groove groove top is positioned at the gravel district is provided with porous disc; The vertical-flow wetland pond is communicated with via the backflow pool that is provided with horizontal drowned flow wetland pond, is provided with sump pump and underwater jet aeration machine in the backflow pool; Described waterproof layer is the plastics material, and waterproof layer is provided with and presets the hole, presets the inboard, hole and is filled with the flexible water filler.
The principle that plant is chosen among the present invention is:
1, the special structure form that is fit to vertical current-horizontal drowned flow combined artificial wetland;
2, the absorbing enriched ability to the heavy metal in the trade effluent and other pollutents is strong;
3, fast growth, with short production cycle, the biological yield height;
4, can plant repeatedly, repeatedly prune;
5, have flourishing root system tissue, and have pest-resistant, resistance against diseases.
Wherein, the Stenocalyx micheli, Herba pteridis vittatae, Phytolacca acinosa, the Li Shi standing grain, cyperus alternifolius, this several plant of Indian mustard both can have been planted in the vertical-flow wetland pond, also can plant in horizontal drowned flow wetland pond, because of its according to cultivation situation difference, the cane length of plant itself is also different, look the upgrowth situation of selected female parent, if the cane height of being cultivated is not high, less than 50cm, then should not plant in the horizontal drowned flow wetland pond in this vertical current-horizontal drowned flow combined artificial wetland, because the plant of planting in the horizontal drowned flow wetland pond need pass the vertical-flow wetland pond on upper strata.
This is because plant is the important component part of artificial swamp, in system, play a crucial role, show that mainly root system of plant discharges oxygen in matrix, root system of plant is fixing plant bed, change the waterpower transmissibility, create the biocenosis condition, aspects such as the aesthetic of landscape effect of root exudates kill pathogenic bacteria and plant.Because the difference of floristics configuration and the characteristics such as continuous variation of concentration of wastewater, the various characteristics of artificial swamp and function also can change thereupon, thereby influence treatment effect and the landscape effect of plant.Therefore we set about from plant, at vertical current---the constructional feature of horizontal drowned flow combined artificial wetland, according to experiment and practice, design above-mentioned effective plant arrangement scheme.
Adopt the beneficial effect that technique scheme produced to be: the used cost of this plants configuration method is low, the heavy metal in the trade effluent and other pollutents are had very strong absorbing enriched ability; The plant growth rate that adopts fast, the output height has enriched the Plant Diversity of artificial swamp, has landscape effect preferably.
