Description
Technical field
The present invention relates to pollution control fields, and in particular to a kind of rapid integrated repairing method in heavy metal pollution lake.
Background technique
Lake is the important material base that the mankind depend on for existence and development, is fresh water accumulation library important on the earth, earth's surface
Available freshwater resources 90% are all accumulated in lake.China is the country in lake more than one, is spread all over the place in inland lake,
It is multi-point and wide-ranging, reinforce management and protection to lake water quality, is one of the vital task of water resources management and protection.In portion, China
Region-by-region, there is mineral resources abundant, and the development and utilization of mineral resources also can while bringing huge economic benefit
Generate many troubling environmental problems.It such as digs up mine, smelt industry and can generate the waste water of the heavy metal containing high concentration, these are useless
Water is directly discharged into lake if unprocessed, generates significant damage in lake and periphery animals and plants, or even threaten
The life security and health of the mankind.
Heavy metal pollution of water body is primarily referred to as bio-toxicity significant Hg, Cd, Pb, Cr, and it is virose to additionally include tool
Zn, Cu, Co, Ni, Sn, V etc..They are enriched in soil and organism, contaminated soil and crop, growth, yield to crop
There is larger harm with quality, and food chain can also be entered by crop rich absorbent, there is the damage mankind and animal health
Potential danger.Wherein, heavy metal Cd is pollutant important in environment, usually exists jointly constitute compound dirt in nature
Dye, is mostly non-degradable type noxious material, does not have natural purifying ability, once it is difficult to therefrom remove into water body.In recent years
Come, with urbanization, the development of process of industrialization, heavy metal element is got worse to the pollution of environment and to the destruction of ecology,
Especially sudden heavy metal pollution, seriously threatens the survival and development of the mankind.
It is mainly the following method: 1, phytoremediation currently, administering to repair for lake pollution, phytoremediation technology is
Using the heavy metal in plant removal water environment, the heavy metal pollution in water environment, this technological investment and maintenance cost are reduced
It is low, it is easy to operate, it not will cause secondary pollution, more adapt to the requirement of environmental protection, and there is potential or distinct economic etc.
Advantage, but due to the difference of the factors such as polluted-water, rehabilitation plant self-characteristic, screening suitable rehabilitation plant just becomes a huge sum of money
The phytoremediation technology for belonging to polluted water region is promoted and the core and key point of practical application；2, biological prosthetic, biological prosthetic skill
Art is to grow up recent years, is had using pseudomonas, saccharomycete and mould etc. to higher concentration heavy metal ion
The microorganism of tolerance removes the heavy metal ion intake bacterium in waste water again into the cell；3, physical chemistry reparation, physical chemistry
Recovery technique contains many specific processing methods, as chemical precipitation, solvent extraction, ion exchange, UF membrane, active carbon and
Silica gel absorption etc., at high cost, complicated for operation, higher to equipment and technical requirements, above every kind of recovery technique has advantage, also has
Certain defect.
The patent that notification number is 105254017 A of CN discloses a kind of eutrophication, heavy metal-polluted water ecology synthesis
Processing method.Prior art low efficiency, for this purpose, this eutrophication, heavy metal-polluted water ecology synthesis processing method are being fed
Mouthful, by high speed steel wire rope type root leaf separation cutter by the water hyacinth on the roomy water surface of fore into cutting, cauline leaf, root after cutting
Portion is collapsed by the side wall of horn-type feed port, concentrates, and thick-layer is formed, by root chain-bar type transmission net and cauline leaf chain-bar type transmission net
It collects, it is high-efficient；Using special drying device, sunning dehydration is carried out to floating plant, accurately sloughs the water of 60-70%
Point, improve amount of dry matter and the nutrition of floating plant.The present invention is suitble to for enclosed waters such as lake, the ponds in inland or has deposited
The processing of eutrophication pollution and heavy metal pollution is carried out in open waters such as river, the water channels that water hyacinth, water peanut are invaded, is
The powerful mean administering water pollution, turning waste into wealth.
