Abstract

Provided is a novel ecological floating island. A main body is a water pool in inverted trapezoid shape, the water pool is integrally formed by glass steel, a water inlet and an overflow opening are arranged on the water pool, and a plane of the overflow opening is higher than that of the water inlet. A floating body in a floating island body is a multi-layer bamboo raft and accumulates into an inverted trapezoid structure. Meanwhile, a gravel coating is arranged on the floating body and serves as a vegetation layer, wetland plants are planted on the gravel coating, the lower portion of the floating body is provided with a water body layer, and freshwater fish are cultivated. The novel ecological floating island has the advantages of purifying water quality of city sewage, building a small-sized ecological environment, improving views, and being suitable for popularization and application in city sewage treatment areas.

Description

A kind of novel ecological chinampa

Technical field

The utility model relates to the biopurification field, is specially a kind of novel ecological chinampa for city domestic sewage being carried out subsequent disposal.

Background technology

Sewage treatment industry generally adopts artificial swamp to the subsequent disposal of sanitary sewage at present, in simple terms, this artificial swamp have advantages of build and working cost cheap, simultaneously with low content of technology, be easy to safeguard, can carry out effectively reliably wastewater treatment, buffering is to the impact of waterpower and pollution load, and in addition, this artificial swamp also can provide and indirectly provide some other economic product benefits simultaneously.But, this artificial swamp also exists some insoluble shortcomings simultaneously: it easily stops up, working life is not long, be subject to the disease and pest impact, simultaneously, design and operation parameter out of true, therefore normal because design is improper makes water outlet not reach design requirements or can not qualified discharge, and somebody worker's wetland has become source of pollution on the contrary.

In this case, the artificial ecological floating island technology is arisen at the historic moment, and ecological floating island is a kind of water quality for eutrophication, utilizes ecological engineering principle, the artificial floating island of the content of the COD in the degradation water, nitrogen, phosphorus.It can make water transparency increase substantially, and water-quality guideline also is improved simultaneously, particularly algae is had good inhibition.The chinampa plant has not only been built the view of the water surface, is carrying out photosynthetic the time, and the CO2 around absorbing discharges O2, is purifying simultaneously air; Plant has transpiration in process of growth, transpiration is by plant stomata transpiring moisture adjusting ambient temperature.Therefore, the photosynthesis of ecological floating island plant and transpiration are being regulated the microclimate of the water surface, and this good microclimate is suitable for the habitat of birds etc.Because the shaded effects on chinampa, venturi effect etc. have been created the good condition of Fish Survival.But the content of the COD in the oxygen-enriched environment that the root system of what is more important NH-2 chinampa plant forms in water and the efficient degradation water of the microbial film on root system surface energy, nitrogen, phosphorus, and suspended substance in the saccharan energy active adsorption water of the interior microorganisms of root system film.But at present in floating island, using is the chinampa that plastic foamboard is made more widely because the defective of foam materials so that long-lasting all being difficult to of the convenience of the manufacturability that the chinampa makes, maintenance and use embody.

The utility model content

The technical problem that the utility model solves is to provide a kind of novel ecological chinampa, to solve the shortcoming in the above-mentioned background technology.

The technical problem that the utility model solves realizes by the following technical solutions:

A kind of novel ecological chinampa, its main body is an inverted trapezoidal pond, described pond is that glass reinforced plastic is one-body molded, have water-in and overflow port on it, and the overflow port plane is higher than the water-in plane, and the buoyancy aid in the body of island, chinampa is the multilayer bamboo raft, and be piled into inverted trapezoidal structure, utilize inverted trapezoidal glass fibre reinforced plastic integral pond and trapezoidal bamboo raft, can effectively control the lower limit screens on chinampa, prevent from that the people from holding to fall into the pond, simultaneously, the sandstone coating is set thereon is implanted with wetland plant as vegetable layer and kind, the bottom is the water body layer, and cultivation has freshwater fish.

In the utility model, the fish of raising in its water body layer are the ecological fish of catfish, these two kinds of strong vitality of snakeheaded fish, and can effectively kill has the worm of falling ill and a bacterium in the sewage, prevent spreading of disease.

In the utility model, all adopt check valve on described water-in and the overflow port.

Beneficial effect: the utlity model has and purify water, create the biological space of living, improve the integrated functions such as view, wave absorption, and owing to using the trapezoidal glass reinforced plastic of trapezoidal bamboo raft respective outer side edges pond, can be difficult to recover the lakes and marhshes of bank waterplant band or be widely used in the closed waters such as pond that have view to require at the large reservoir of water-level fluctuation, because of the reason of wave.

Description of drawings

Fig. 1 is the schematic diagram of the utility model preferred embodiment.

Embodiment

For technique means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

Schematic diagram referring to the preferred embodiment on a kind of novel ecological chinampa of Fig. 1, in the present embodiment, water-in 1 is positioned at the bottom, left side in trapezoidal glass reinforced plastic pond 6, and overflow port 4 is positioned at the right upper portion in trapezoidal glass reinforced plastic pond 6, island, chinampa body in the 6 pond bodies of trapezoidal glass reinforced plastic pond by trapezoidal bamboo raft 5 as buoyancy aid, sandstone soil layer 3 on it is the plantation layer, and wetland plant 2 of plantation is yellow flag and cattail on it.

Trapezoidal bamboo raft 5 bottoms are the water body layer, and cultivation has freshwater fish 7 in it, in the present embodiment, employing be catfish and the snakeheaded fish that possesses stronger water body cleaning capacity, in order to the purifying water body environment, killing has the worm of falling ill and a bacterium in the sewage, prevents spreading of disease.

Above demonstration and described ultimate principle of the present utility model, principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification sheets just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
