Description
Technical field
The invention belongs to water treatment field, and in particular to a kind of compounded mix biological floating bed applied to combined type triple effect
Preparation method and applications.
Background technology
Biological floating bed is a kind of water body in-situ recovery technique risen in recent years.At present, the technology is in lake eutrophication water
It is widely used in the purification of body and fishery cultivating waste water.The technology has without taking up an area, cheap, easy for installation, reparation
The characteristics of effect is good, operational management is simple.
By years of researches and practice, researcher has found traditional following deficiency of biological floating bed presence:(1) root system of plant
It is suspended in water body and is easily swallowed by herbivorous animal;(2) biomembrane of floating bed plant root system apposition growth is limited;(3) floating bed pair
Plant root fixed effect is bad, and plant easily floats, so as to cause floating bed clean-up effect not good enough.In recent years, researchers send out again
Now artificial swamp is combined with biological floating bed technology, biological floating bed middle using with bio-carrier and matrix suction-operated
Bifunctional material, can the more powerful wetland type of constructing function it is combined biological floating bed.Since this novel ecological floating bed is integrated with
Plant absorption, filtrate absorption and bio-film colonization triple function are in one, therefore also known as combined type triple effect is biological floating bed.It is Chinese special
Profit 2012101630837 discloses a kind of complex ecological floating bed for providing habitat and uses at least one of zeolite and biological ceramic particle
As filler matrix, Chinese patent 2014106492847 discloses a kind of combined biological floating bed equipped with floating ball, its filling base
Matter is mixed by magnesium slag ceramic filtration ball, bentonite clay particle and zeolite and formed.Combined biological floating bed filling substrate is mainly at present
Used after one-component filler, or a variety of single filler simple physical mixing as mixed fillers.
In recent years, chemical fertilizer is excessively used in planting industry production process, causes to have accumulated a large amount of nitrogen P elements in soil.
Under the driving of rainfall and irrigation, these phosphorus and nitrogens enter water by agricultural surface runoff, agricultural drain and underground percolation
Body, causes body eutrophication.The loss of farmland nitrogen phosphorus be cause China's water environment degradation and lake eutrophication it is important because
Element.It is biological floating bed as a kind of cost is low, water body purification technology in situ of easy care have in Control of Agricultural Non-point Source Pollution it is wide
Wealthy application prospect.But due to being influenced be subject to factors such as rainfall intensity, dose, fertilization time, fertilizer types, farmland face source
