Description
Technical field
The application belongs to environment remediation technical field, and river course, lake, landscape water body are used for more specifically to one kind
Bio-stimulant of reparation and its preparation method and application.
Background technology
River course, lake, landscape water are the Main River Systems in city, with urbanization process quickening and industrial or agricultural it is swift and violent
Development, city function is stronger and stronger, and water pollution is also severe all the more.A large amount of undressed municipal refuse, industrial wastewater, lifes
Sewage living, contaminated soil and atmospheric fallout are continually drained in river course, lake and landscape water, cause the serious of water body
Pollution, and threaten the health of the mankind.
Although water body has certain self purification, when the total emission volumn of pollutant has exceeded it from net capacity, water body
Original state then can not be voluntarily returned to, the whole environmental system appearance of water body is unbalance, and pollutant increases, and causes some with this
Pollutant is material, the preponderant algae amount reproduction in energy source, aquatic ecosystem is seriously damaged, and causes water body
Eutrophication.If without cut-out external source pollution in time, the pollutant in water body is cumulative, and aerobic microbiological will largely disappear
Oxygen in water consumption body, makes water body change into anaerobic condition, causes anaerobic bacteria amount reproduction, organic matter corruption, decomposition, hair
Ferment, is converted into the malodoring substances such as ammonia nitrogen, humus, hydrogen sulfide, methane and mercaptan.OUR is more than during this process causes water body
Reoxygenation speed, causes the foul smell of anaerobic environment, generation to escape the water surface, and the heavy metal such as iron, manganese is reduced in water, with the sulphur shape in water
Into compounds such as ferrous sulfides, the suspended particulate of a large amount of negatively charged colloids for having adsorbed FeS, MnS is formed, make water body blackening, become
It is smelly.
For the improvement that above-mentioned river course, lake, the black foul sewage of landscape water body contaminate, current most efficient method is that biology in situ is repaiied
Recovering technology.Microorganism in situ is added using the indigenous microorganism or external source in water body repair polluted-water with efficient, low cost
