Description
Technical field
The present invention relates to a kind of new restoration of the ecosystem agent.
Background technology
As industrial or agricultural is fast-developing, a large amount of sanitary wastewaters and part industrial wastewater rich in organic matter are discharged into river, lake
Pool, causes to decline to a great extent to oxygen content of water, causes river and lake that organic with serious pollution phenomenon is generally presented.It is a large amount of dirty
Dye thing deposits to river, lake-bottom, causes bed mud to be chronically at anaerobic environment, is progressively degenerated in the case where anaerobe acts on,
Cause river course blackening, smelly.At present, the river improvement method to municipal pollution has a desilting, microorganism aeration, water plant and
In-situ immobilization etc..Conventional desilting construction investment is big, cumbersome, and mud moisture content is high, and transport and disposal are difficult；Microorganism is aerated
Maintenance cost is big, and thinks little of bed mud and aquosity in-situ immobilization；Water plant is decomposed such as maintenance in time, easily corruption, is ruined
Water body, later stage plant treatment cost is high, easily causes secondary pollution, so causes Bian Zhibianhei in urban river regulation.It is and former
Position restoration of the ecosystem method adds restoration of the ecosystem agent at normal temperatures and pressures can condense heavy metal and organic pollution in sewage quickly, lead to
Peroxidating bed mud sulfide eliminates black smelly, activation bed mud indigenous microorganism, reparation water body activity and biosystem, fundamentally changes
Kind water quality of river and raising water body self-purification ability；The applicant prepares a kind of new restoration of the ecosystem agent on this basis, with reference to
Different pollution of river characteristics, adjust its component, by condensing, adsorbing, redox, chelating fix, the physics such as separation and precipitation
Chemical process, restoration of the ecosystem in situ is carried out to bed mud, to meet the needs of existing market.
The content of the invention
The technical problem to be solved in the present invention is to overcome the defects of existing, there is provided a kind of new restoration of the ecosystem agent, with reference to
Different pollution of river characteristics, adjust its component, by condensing, adsorbing, redox, chelating fix, the physics such as separation and precipitation
Chemical process, restoration of the ecosystem in situ is carried out to bed mud, meets the needs of existing market.
In order to solve the above-mentioned technical problem, the invention provides following technical scheme：
A kind of new restoration of the ecosystem agent, it is characterised in that：Including following composition：
