Description
Technical field
The utility model relates to the technical field of wastewater treatment and soil remediation more particularly to a kind of processing of compound wastewater and
The device of soil remediation.
Background technique
As people are continuously increased aquatic products demand, mariculture industry is rapidly developed in recent years, is supported
It is also intensive to height intensivization development from half to grow mode, and then threat is also constituted to surrounding body environment and the ecosystem.
It may include in being drained outside sea-farming from the particulate form solids of excrement and feed, solubilised state metabolic waste, solubilised state
Nutritive salt, anti-microbial agents and medicament residue etc. can lead to cultivation water and vicinity waters eutrophy after it is largely discharged
Change or water quality deterioration, jeopardize the marine eco-environment, while also constraining the sound development of mariculture industry.Marine culture wastewater by
In with the effect of salinity, pollutant composed structure has differences with Lu Yuan sewage, increases processing difficulty.Currently, physics, change
Learn and biological method be more commonly used sea-farming outlet water treatment technology: physical method: mainly have filtering, precipitating, air bearing,
Absorption, aeration, foam fraction factor etc.；Chemical method: mainly there are Ozone, coagulant sedimentation, electrochemical process etc.；Biological method: main
Want active sludge, biofilm (such as biofilter, biological rotating disk, biological roller), complex microorganism preparations method etc..
Soil is the material base that the mankind depend on for existence and development, is the basic means of production of agricultural production.But with dirt
Water irrigates, the mankind's activities such as largely use of chemical fertilizer and pesticide cause so that multiple pollutant enters soil by all means
Heavy metal pollution of soil, so as to cause soil degradation, ecological disruption, and enters organism by geochemistry chain, food chain
And then jeopardize human health and life security.The research for having carried out more contaminated soil remediation technology both at home and abroad, is mainly turned over visitor
Physical chemistry recovery technique based on soil removal and replacement, passivation, elution, electrochemical rehabilitation, chemistry are the methods of fixed and with plant, microorganism
With the bioremediation technology based on animal, it may be said that be to cut both ways, however still lack economical and efficient and environmental-friendly at present
Technology removes pollutant from contaminated soil.
Artificial wet land treating system is a kind of sewage disposal technology to grow up the 1970s, because having processing effect
Fruit is good, builds the advantages that management low with operating cost, easy to maintain and the most attention by countries in the world, becomes and sends out in recent years
Open up a kind of faster New Technology about Wastewater Treatment.The main physics using this complex ecosystem of matrix-microorganism-plant, change
Triple coordinative roles of and biology are realized by filtering, precipitating, ion exchange, plant absorption and microorganism decomposition to useless
The high-efficient purification of water.Eutrophication water, landfill leachate, livestock breeding wastewater, food wastewater etc. is now widely used for control
Reason.It is mainly widely used in fresh water sewage treatment field, and the research outside sea-farming in terms of drainage sunk well is more few
See.
Although currently, did numerous researchs respectively to soil remediation and cultivating wastewater purification both at home and abroad, at present no matter which kind of
Method treatment effect is not ideal, or processing after it is not up to standard, or individually processing cause cost too high and can not be promoted
Using.It is compared with sanitary sewage with industrial wastewater, the major pollutants of marine culture wastewater are nutritive salt (nitrogen and phosphorus), and concentration
It is relatively low, a certain amount of suspended solid and dissolved organic matter are existed simultaneously, water transparency is influenced.Cut down the nitrogen in waste water
Phosphorus content could fundamentally solve the eutrophication problem in corresponding receiving sea area, therefore such cultivation containing nutritive salt is useless
Water is urgently handled.
Due to the difference of pollutant structure and common Lu Yuan sewage in seawater salinity effect and breeding wastewater, current needle
It is less to the proprietary technology of marine culture wastewater processing.In Artificial Wetland Techniques, conventional manual's wetland plant usually can not be
It is grown under the high salinity environment of marine culture wastewater；Secondly as the decomposition of remaining nitrogenous feed and fish excreta, is being closed
Breeding water body in the nitrite etc. that is generated containing more Ammonia substance and nitration reaction, have strong toxicity to fish,
It is the important goal of circulating seawer cultivating wastewater purification, and traditional artificial wet land filler bed is by the good of plant root zone oxygen supply
Oxygen environment, therefore the denitrifying scarce capacity of anoxic microbial in system, particularly with the lower circulating seawer breeding wastewater of C/N
It is unable to satisfy the denitrogenation processing requirement of system；Third, the matrix such as sand, gravel that existing artificial swamp is widely used make filler,
Phosphor-removing effect is only 30%~50%, and effluent quality cannot reach the requirement of water quality standard for fishery, and the adsorption saturation service life is general
Only 3~4 years, it is unable to satisfy the processing requirement of circulating seawer breeding wastewater.More there is not marine culture wastewater processing joint
Specific soil restoring technology.
Utility model content
For the defects of above-mentioned field, the purpose of this utility model is to provide for a kind of while realizing efficient process sea
The device of water breeding wastewater and soil remediation, the purification of waste water and soil remediation effect of this method energy stable for extended periods of time, is based on
The screening of plant and the Reasonable Arrangement of matrix, cooperation collaboration processing marine culture wastewater and polluted soil, and achieve good
Practical value.
To achieve the goals above, the technical solution of the utility model is: a kind of processing of compound wastewater and soil remediation
Device, including sewage collection system, filter device, deflector anaerobic reaction tank, biological contact oxidation pond and artificial swamp；Described
Artificial swamp includes that downstream pond and upstream pond, respectively filling substrate and volume ratio are 2: 1, in the downstream pond under
