Abstract

The invention provides a tidal river sewage treatment and aquiculture integrated system which comprises aquaticplant floating blanket zones and a freshwater mussel culture zone arranged in the tidal river, wherein the freshwater mussel culture zone is arranged in the middle of the tidal river; and the aquaticplant floating blanket zones are arranged at two sides of the freshwater mussel culture zone. The aquaticplant floating blanket zones are divided into an emergent aquatic plant zone, a floating plant zone and a submerged plant zone according to the decontamination capability. Since emergent aquatic plants, floating plants and submerged plants are sequentially cultured in a riverway disclosed by the invention, the riverway is progressively purified layer by layer. In addition, different aquaticplants are subjected to reasonable companion planting and have purification capability all year round. The mussels in the freshwater mussel culture zone in the invention not only can be used for filtering phytoplankton and reducing algal bloom, but also can be used for ensuring that no heavy metal substances exist in meat of the mussels.

Description

Tidal river waste water treatment and aquaculture integrated system
Technical field
The present invention relates to waste water treatment and aquaculture field, be specifically related to waste water treatment of a kind of tidal river and aquaculture integrated system.
Background technology
In recent years, waters such as some lakes, river course are subjected to the puzzlement of environmental pollution, and the situation of body eutrophication is serious day by day: original submerged vegetation decline, ecotope suffers serious destruction.The equal occupancy volume of water resource is few per capita in China, and spatial and temporal distributions is uneven, makes that existing water resource imbalance between supply and demand is more outstanding.At present, the method for polluted water purification comprises that mechanical filter, materialization absorption, chemistry kill algae, add single technology such as microbial bacterial agent, the water quality of China purify with restoration of the ecosystem in application is all arranged.But often expense is high, power consumption is big for physical chemistry method, only is adapted to the purification of small water, throws in microbial bacterial agent and then exists bigger secondary pollution dangerous.
Existing biological method is administered Technology of Sewage, mainly is to utilize floating bed, chinampa to carry out waste water treatment, and it is also few to utilize animals and plants to subdue the method for eutrophication material in the water jointly.Application number " 201010105909.5 ", the Chinese patent (application) of denomination of invention " a kind of sewage disposal system and sewage water treatment method " discloses a kind of method for reducing to narrower river course, non-morning and evening tides rural area eutrophication material.Application number " 200710151009.2 ", denomination of invention " method of silver carp and hyriopsis cumingii combined algae-controlling " discloses a kind of silver carp and the method for hydriopsis cumingii control algal tufa to purify water utilized.But also there are different problems in said method: the Ah's rich nutritive material that does not 1. solve river course more large-scale, that tidal phenomena is arranged is subdued problem.2. lean on animal to repair polluted-water merely, clean-up effect is not obvious, and the water body dissolved oxygen can not increase.3. animal dead can cause bigger problems such as pollution to water body.
Summary of the invention
Technical problem to be solved by this invention is, in order to overcome the problem that exists in the prior art, waste water treatment of a kind of tidal river and aquaculture integrated system is provided, and strengthens the restoration of the ecosystem function in morning and evening tides river course, improves water quality.
In order to address the above problem technical scheme of the present invention is such:
Tidal river waste water treatment and aquaculture integrated system is characterized in that, comprise, are arranged at floating blanket district of water plants and freshwater mussel culture zone in the tidal river.
Preferably, middle part, said tidal river is located in said freshwater mussel culture zone, and the floating blanket district of described water plants is located at both sides, said freshwater mussel culture zone.
Preferably, the floating blanket district of said water plants is divided into emergent aquactic plant district, fluitante district, submerged plant district successively by dirty removal capacities.
Preferably, said emergent aquactic plant is selected from water peanut or/and wild rice stem, and said floating plant is selected from big algae or/and weter hyacinth, and said submerged plant is selected from one of watermifoil, waterweed, eel grass, hydrilla verticillata, water caltrop or hornwort or two or more combination.
Preferably, the floating blanket in the floating blanket district of said water plants avoids floating plant to waft for the fixing fishing net structure of bamboo stake.
Preferably, laterally draw in the net to restrict in said freshwater mussel culture zone, nettle is spaced apart 1 meter-1.5 meters, hangs oneself at nettle and supports hydriopsis cumingii.
Preferably, be provided with railing between floating blanket district of said water plants and the said freshwater mussel culture zone and isolate, and on described railing, be provided with and laterally draw in the net the bindiny mechanism that restricts, as incise or link up with.
Preferably, said river course is the morning and evening tides river course, to 500 meters of the youthful and the elderlys, and wide 15-20 rice, 1 meter-5 meters of the degree of depth.
Preferably, the floating blanket section length of said every side water plants is said freshwater mussel culture zone 3/4.
Operation principle of the present invention is: the water (flow) direction of tidal river can change, so cleaning system is wanted the both sides symmetrical expression.The higher sewage of nitrogenous phosphorus flows into the river course, through emergent aquactic plant interception sand grain, it is sunk, and the particle of sinking is that emergent aquactic plant provides abundant nutriment to make its growth, and this also makes the transparency of water improve.The floating plant growth is rapid, rapidly heavy metal, nitrogen phosphorus etc., further free eutrophication material in the submerged plant absorption water in the absorbing enriched water.To the middle part, the hydriopsis cumingii drainage is eaten up less phytoplankton, and in the water environment of a few heavy metal, grows, and provides a kind of health non-harmful aquatic products.
Hornwort, watermifoil etc. are better in growth spring and summer, and can change hardy plants such as hydrilla verticillata and water caltrop winter into, ensured the clean-up effect in winter.Fluitante is caught with fishing net, avoids spreading of fluitante like this.
Because adopt technique scheme, compared with prior art, the present invention has the following advantages:
1. because cultivating emergent aquactic plant, fluitante and submerged plant successively in the river course, the present invention makes that the river course purification is progressive.And the reasonable companion planting of different water plants, detergence(-cy) is all arranged the whole year.
2. the bivalves of freshwater mussel of the present invention culture zone both can the filtering phytoplankton, reduced the wawter bloom algae, can guarantee that again its meat does not contain heavy metal substance.
3. the present invention is applicable to the morning and evening tides river course, and application is extensive, and cost is lower, and safety and environmental protection does not produce secondary pollution.
