Description
Technical field
The present invention relates to water remediation agent field, more particularly, to it is a kind of can biofilm anaerobic organism flora porous mine
Composition granule and its preparation method and application.
Background technique
The water-based pollution of the flowing such as river, lake, irrigation canals and ditches, fish pond (mostly with micro- pollution presentation) difficulty of governance is big, and main cause exists
Wide in its drainage area, unpowered power supply is supported, some traditional waste water control methods is caused to be difficult to carry out.Such as aerobic biochemical process
Aeration, physically or chemically the stirring in method and water body conveying, thickening filtration etc. need the process of power support；Even
Conventional chemical method, since such water body is related to ecological, environmental protective problem, being also very limited, (some chemical agents are banned
It only uses).Such water pollution improvement meets real needs, but lacks conventional effective method again at present.
Using simulation nature water natural purification process, as water by the filtering of soil Minerals, absorption, ion exchange,
Bioconversion, root system of plant absorption etc., are a good directions.Because it does not need power consumption and the pollution of non-generation environment,
It is very suitable to such water pollution improvement, in recent years by the concern of environmental protection industry (epi) and researcher, especially anaerobic organism bacterium
Biological einforcement method cooperates adsorption filtration method again, has small-scale application, and have better effects.But there is also some problems, one
It is that current water is very easy to lead to the loss of anaerobic organism bacterium, can not ensure anaerobic organism bacteria concentration or quantity, thus seriously
Influence regulation effect；The second is anaerobic organism bacterium after pollutant, can generate sludge simultaneously, can not remove in time in consumption water body
Processing, equally will cause secondary pollution.It can be floated in water body using natural porous clay minerals particle modularization assembling
Carrier nest come cultivate anaerobic organism bacterium flora, it can be achieved that energy free consumption biological reinforced system for handling, while in clay class
