Description
Technical field
The present invention relates to a kind of algal controls to consolidate preparation and the polluted water body repairing method that phosphorus denitrogenates particulate vector, belongs to water process
Technical field.
Background technology
At present, China's majority urban water-body eutrophication is serious, and " green congee " phenomenon is apparent.It is analyzed main reason is that city
The nourishment source of city's water body (city inland river and inland lake) mostly come from by after city domestic sewage and Industrial Wastewater Treatment again
Unboiled water, but recycled water enter water body after its pollutant can constantly be enriched with, eventually lead to nitrogen, phosphorus, organic matter in urban water-body water quality
It is exceeded;Another reason be by a large amount of nutritive salt of the modes such as atmospheric sedimentation, rain drop erosion, heavy metal, organic matter again into
Enter urban water system, so as to cause the collapse of the urban water system ecological balance, exacerbate water body eutrophication and, algae is spread unchecked.
Mainly there are dystopy treatment technology and in-situ treatment technology to the method for urban water-body eutrophication pollution reparation now.
Polluted-water mainly will be guided to sewage treatment plant after Sediment Dredging and carries out strange land processing by dystopy treatment technology, and wherein bed mud is dredged
It is to dig out river and lake contaminated sediments using waterpower or mechanical means to dredge, and is released by removing bed mud reduction pollutant
It puts.Though this method can obtain relatively thorough effect in a short time, the time, slightly long body eutrophication can occur repeatedly;Separately
Outside, since showering need to excavate bed mud, transfer water body, required engineering equipment is more, costly, and the structure of destructible bed mud is led
The destruction of the city eutrophication water ecosystem is caused, later stage recovery needs the long period.In view of the foregoing, dystopy processing skill
Art is generally applied in laboratory simulation experiment or the relatively small water remediation of Polluted area area more.And in-situ treatment technology
Mobile bed mud and water body position are not required to, cuts off the dirt of pollution sources by taking certain measures that pollutant is prevented to enter water body first
Then dye approach reduces the pollutant load in river, water body in lake and bed mud by using physics, chemistry and biological method
And pollutant solubility, toxicity and migration can be reduced simultaneously.It is sent out by the comparison of dystopy treatment technology and in-situ control technology
Existing, urban water-body in-situ control technology has that investment smaller, operation are more easy to and secondary pollution is less etc. excellent with respect to showering technology
Point is the inevitable requirement and development trend of urban water-body eutrophication remedy and sustainable development.However domestic water body in-situ is repaiied
Recovering technology is limited the problems such as developing high pollutant concentration still in by water body and bed mud and complicated component.
Mainly have at present with regard to the removal of Measures of Algae in Water Body simultaneously:Dispensing algae removal method, adds copper sulphate, chlorine, sodium hypochlorite etc.,
But these methods are of high cost, while can also be with the ecosystem of influence water body;Solid-liquid isolation method, it is direct by micro-filtration, sand filtration etc.
Filtering;Air supporting and reinforced deposition etc..These methods are usually invested big, of high cost, elimination and are not thorough.
According to《Water prevention and cure of pollution action plan》, will there is the rich battalion such as prominent total nitrogen, the total phosphorus influenced on quality of water environment
Fosterization index incorporate basin, regional pollution object prediction emission the binding indicator system, and be distinctly claimed stringent control
The total nitrogen of eutrophication, total phosphorus index.Clear understanding arrives people, controls city eutrophicated polluted water, improves municipal water
Ecological environment ensures water quality safety, realizes urban ecology civilization, has been the task of top priority.Therefore the high, pollution to eutrophic extent
Serious river and lake realize that science, stabilization, quick repair process are one of China's key subjects urgently to be resolved hurrily at present,
And it especially needs that new technology and methods is researched and developed effectively to reduce nitrogen, phosphorus, heavy metal and the chemical oxygen demand in eutrophication water
The polluters such as amount.
In short, solve the problems, such as that it is many that polluted water body still has from algal grown is inhibited at present;It gets dirty in removal
P (phosphorus), N (nitrogen) etc. in water body are contaminated, there is also numerous limitations.
Invention content
The object of the present invention is to provide that can reduce total phosphorus in water, total nitrogen, inhibit algal grown or kill algae so as to
