Description
Technical field
The present invention relates to improve coastal waters bottom anoxic conditions field, particularly relate to a kind of trend pump
Formula artificial sinking device.
Background technology
Dissolved oxygen (Dissolved Oxygen, DO) is the important indicator that water environment is healthy.Many river mouths, the world and
All there is the phenomenon of seasonal hypoxia (hypoxia, DO < 2mg/L, Fig. 1 a) in immediate offshore area, by 2009
Year, the anoxic zone that the whole world has been reported reaches 245000km more than 400 (Fig. 1 b), the gross area2.China has
There are wide coastline and numerous estuary bays, are faced with the ocean oxygen deficit problem of sternness equally.The longest
Jiangkou, outside the river mouth such as the mouth of the Zhujiang River, marine site has anoxia to report.Data in recent years show, Outer Changjiang estuary anoxia
Marine site (DO < 2mg/L) area is more than 20000km2, DO minimum is less than 1mg/L (Fig. 2), hypoxia
The frequency of appearance, scope, persistent period, intensity have the trend substantially risen.
There is more anoxic zones in the coastal waters that population activity is intensive, has become as global
Significant Problems of Eco-environment.Anoxia by change water body chemical cyclic process, destroy the original ecology in this waters and put down
Weigh, cause body eutrophication aggravation, harmful heavy metal ions release, and affect halobiontic physiology machine
Energy, area distribution, structure of community and bio-diversity, serious anoxia can cause halobiontic death (figure
1a).It is about ten thousand tonnes of carbon/years of 34.3-73.4 due to the Biomass of anoxia loss in global range.In anoxic zone
In, original marine eco-environment is destroyed, if developing as one pleases, may break out disastrous effect,
Whole coastal waters ecosystem is caused to collapse.
The approach improving coastal waters bottom anoxia mainly has two, and one is to control land source emission, subtracts
Few organic production and decomposition, reduce water body oxygen consumption, but along with the continuous aggravation of littoral mankind's activity, generation
In boundary, the nutrient substance input of most coastal waters likely continues to increase；Two is vertical by water body
Exchange and go stratification, promote the dissolved oxygen diffusion to bottom water body, increase supplementing of bottom water body dissolved oxygen, this
Approach realizes possibly through engineering means such as artificial ocean mixing.
Artificial ocean mixing, as a kind of earth engineering method, including artificial upper up-flow and artificial sinking, is
The study hotspot in Marine Sciences field and advanced subject in recent years.Wherein, seabed nutritive salt is promoted to by the former
Euphotic layer, improves top layer primary productivity, promotes that marine carbon converges；The latter is to cause ocean by manual system
Middle top-down water body flow.In the anoxic zone of coastal waters, artificial ocean sinking may produce
Raw obvious ecological effect: 1. oxygen-enriched for top layer sea water is injected into bottom anoxia water body by it, thus alleviates bottom
The degree of oxygen deficiency of water body, increases aerobic space；2. strengthen water body vertically to mix, break/weaken water body stratification knot
Structure, thus bottom increasing, nutritive salt is to the conveying of euphotic layer, increases primary productivity, improves offshore fishing grounds raw
State environment.It addition, artificial sinking provides the scientific experiments means of regional environment protection and treatment decision-making, have
Help the change of dissolved oxygen spring layer, water/sediment interface chemical process, the weight probing under artificial sinking disturbance
The biomarker change of metal adsorbed state, microbiologic population's change, compound and correspondence in bed mud
Etc. important scientific problems.Therefore, abroad to the research of artificial sinking technology and application continues to increase,
The trend accelerated.
ECS company of the U.S. (Ecosystem Consulting Service, Inc.) have developed electronic vane type oxygen supplement
Machine, sinking device, jet aerator and aeration-type oxygen-increasing machine.These systems can readily obtain land
The base energy, is effectively realized lake and reservoir goes stratification and water oxygenation function；Tokyo Univ Japan develops
Large-scale density of sea water flow generating apparatus (Density Current Generator, DCG), uses vapour/diesel-driven generator
Energy supply, concurrently forms artificial sinking and artificial upper up-flow with water pump, in temperature after table, bottom seawater being mixed
Spring layer is discharged.This device tests successfully, and is applied to Japan's Gokasyo estuarine environment improvement.Swedish government
In By Fjord fyord, (mean depth 51m, water bottom long term hypoxia) establishes large scale ecological engineering,
Utilize wind-force and electric power that surface seawater pumps into the bottom anoxia water body of 35 meters of degree of depth.The experimentation knot of 2 years
Fruit shows, single sinking device can make the DO content of nearly seven square kilometres of anoxia water bodys increase to from 0mg/L
Average 3.7mg/L, this marine site NH4, P, H2S content significantly declines, and bottom aqueous bio abundance significantly carries
Rise.
The studies above shows that artificial sinking technology is expected to become and alleviates a kind of effective of bottom seawater oxygen deficit problem
Method.But, its Lu Yuan energy-provision way of the device of ECS company of the U.S. is poorly suitable for marine site work；Japan
DCG device is researched and developed for offshore Lagoon, needs continental rise energy supply；Sweden's wind-power sinking device is fitted
For the Baltic Sea, because this marine site wind energy resources enriches.There is electromechanical structure complexity, build in both equipments
If maintenance cost cost is high, on-site maintenance difficult, be difficult to the defects such as long-term operation automatically, thus more difficult
Realize large-scale engineeringization application.
Summary of the invention
For the deficiencies in the prior art, the present invention provides a kind of trend pump type artificial sinking device, this device
Can capture at upper lower nozzle from mechanism simultaneously rise, marine tidal-current energy on ebb tide direction, marine tidal-current energy is converted into pressure
Difference energy, thus by bottom oxygen-enriched for top layer Seawater inhalation, increase the dissolved oxygen amount of bottom water body.By trend pump type
Artificial sinking Innovation Theory introduces, and solves ocean energy self-sufficiency problem, reduces cost, and improving engineering can
Row.Trend pump type artificial sinking technology is expected to that breaks through foreign artificial sinking construction investment is huge, sexual valence
The low predicament of ratio, can low cost construction, economic and environment-friendly, be expected to the Yangtze Estuary hypoxia zone promote demonstration.

With marine loop wheel machine, device being placed into anoxia marine site, whole device is fixed on anoxia sea by pedestal 6
Territory.When flood tide, ebb tide, the current in marine site, anoxic zone can flow, and current have certain speed,
Choked flow pressure inlet 1 mouth of pipe direction above device is consistent with the direction that sea water flows, and sea water passes through choked flow supercharging
The trumpet-shaped mouth of pipe of pipe 1 enters sinking standpipe 3, and sea water enters choked flow pressure inlet 1 by its internal current gear
Sheet 2 is pushed to block the other side mouth of pipe, makes sea water will not be flowed out by choked flow pressure inlet 1, to the greatest extent may be many
Entrance sinking standpipe 3.Choked flow pressure inlet 1 passes through the top layer trend horizontal velocity of upper port and is reduced to
Zero, and in pipe, produce a downward hydraulic pressure.Bottom trend is through Venturi, the speed meeting of current
Increasing, the bottom trend simultaneously accelerated through Venturi forms one in sinking standpipe 3 lower port and bears
Pressure.When the pressure reduction of upper and lower port can overcome density head, sea water mobilization dynamic and pipe internal friction,
Produce the top-down flowing of pipe maritime interior waters, form artificial sinking.The present invention can capture simultaneously rise, falls
Marine tidal-current energy on tide direction, is converted into pressure reduction energy by marine tidal-current energy, thus by bottom oxygen-enriched for top layer Seawater inhalation,
Increase the dissolved oxygen amount of bottom water body.
