Abstract
The utility model provides a strong-oxygen-supplied constructed wetland and belongs to sewage purification treatment equipment in the aspect of water conservation. The strong-oxygen-supplied constructed wetland is structurally characterized by comprising a wetland bed which is arranged in an anti-seepage wall, wherein wetland plants are planted in the wetland bed; water distribution pipes and water collecting pipes are also evenly distributed in the wetland bed; a gas-guide tube and a horizontal tube which are mutually connected are arranged in the wetland bed; the horizontal tube is a microporous aerator pipe; the gas-guide tube extends out of the wetland bed and is connected with an air compressor; and the bottom of the wetland bed is provided with an anti-seepage layer. Compared with the prior art, the novel strong-oxygen-supplied constructed wetland provided by the utility model has the characteristics of reasonable design, simple structure and the like, is strong in oxygen supplying capacity and can be used for effectively purifying sewage.
Description
Technical field
The utility model relates to the sewage purification treatment facility of a kind of water conservancy aspect, a kind of artificial swamp of strong oxygen supply specifically.
Background technology
Artificial swamp is as a kind of emerging sewage disposal technology, and it is efficient, stable, processing capacity has been studied personnel's confirmation easily.Artificial swamp is used widely since the seventies in 20th century, and some American-European countries have built up or building a large amount of artificial swamp sewage treatment projects, obtained good economy and environmental benefit.In recent years, artificial swamp has become a water technology with bright prospect, and developing country also begins to apply.Along with industrial and agricultural development, the increase of pollutant emission, China's water environment pollution problem is serious day by day, not only endangers hydrobiont existence, and threatens HUMAN HEALTH, people's orthobiosis is caused have a strong impact on.At present, government has recognized that the seriousness that water pollutes, and is just taking measures to carry out water pollution control, to China's economics of underdevelopment, wide, the with serious pollution present situation of water of rural areas, needs badly and finds that tally with the national condition, as a to address this problem effective way.Artificial swamp has characteristics such as cost is low, energy consumption is low, easy care, manageability, and protection also has very big benefit to natural ecological environment, and therefore, exploitation artificial swamp water technology has important and far-reaching meaning to China's water pollution control.
Artificial swamp is in the treating processes to sewage; The existence and the necessary aerobic environment that need oxidation, nitrifying bacteria community; And oxidation in the artificial swamp, the needed oxygen of nitration reaction, except that from the dissolved oxygen in the sewage, mainly being transmitted with the plantation plant roots by the reoxygenation on surface provides.Therefore, in operational process, the oxidation of most of wetlands, nitration reaction do not have competent oxygen to support.Make the inconvenience of purification of water quality ability fall flat, even the situation of source of pollution occurs becoming.
Summary of the invention
The technical assignment of the utility model is the deficiency that solves prior art, and a kind of artificial swamp of simple in structure, strong oxygen supply is provided.
The technical scheme of the utility model realizes by following mode, the artificial swamp of this a kind of strong oxygen supply, and its structure comprises and is arranged on wetland bed in the cut-pff wall; Said wetland bed interior the kind is implanted with wetland plant; Above-mentionedly also be evenly distributed with water distributor, header in wetland bed, said being provided with in wetland bed interconnects gas tube, level pipe, and this level pipe is a micropore aeration pipe; Gas tube stretches out the wetland bed air that is connected with, and said wetland bed bottom is provided with an impervious barrier.
Described level pipe evenly is furnished with three layers.
Said level pipe surface coverage one deck periosteum.
Said impervious barrier is the HDPE impervious barrier.
The beneficial effect that the utility model is compared with prior art produced is:
Characteristics such as that the artificial swamp of a kind of strong oxygen supply of the utility model has is simple in structure, easy to use, be skillfully constructed; The setting of air can guarantee wetland bed interior oxygen supply; Reduce obstruction through alternation of wetting and drying; Prolong the work-ing life of wetland, guarantee the degree of purification of sewage simultaneously.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model.
Mark in the accompanying drawing is represented respectively:
1, periosteum, 2, gas tube, 3, air, 4, wetland plant, 5, water distributor, 6, cut-pff wall, 7, level pipe, 8, header.
Embodiment
Below in conjunction with accompanying drawing the artificial swamp of a kind of strong oxygen supply of the utility model is done following the detailed description.
Shown in accompanying drawing 1, the artificial swamp of this a kind of strong oxygen supply, its structure comprises and is arranged on wetland bed in the cut-pff wall 6; Said wetland bed interior the kind is implanted with wetland plant 4; Above-mentionedly also be evenly distributed with water distributor 5, header 8 in wetland bed, said being provided with in wetland bed interconnects gas tube 2, level pipe 7, and this level pipe 7 is for micropore aeration pipe and shown in accompanying drawing, be provided with three layers; Surface coverage one deck periosteum 1 at level pipe 7; Gas tube 2 stretches out the wetland bed air 3 that is connected with, and the periosteum 1 in air 3 level pipe 7 outsides not for level pipe 7 supply air the time can stop up micropore anti-backflow under pressure; Said wetland bed bottom is provided with an impervious barrier, and this impervious barrier is the HDPE impervious barrier.
Above-mentioned wetland plant 4 comprises a kind of in reed, cattail, Canna generalis Bailey, thousand fiddleheads, giantreed, the Chinese celery or several.
