Description
Technical field
The present invention relates to organic dirty (useless) water treatment facilities, and in particular to basalt fiber cover type perpendicular flow artificial is wet
Ground.
Background technology
Artificial swamp utilizes plant-matrix-microorganism in the ecosystem as a kind of novel ecological sewage disposal technology
Joint effect play triple synergistic effects of physics, chemistry and biology, realize the purification to sewage.Due to construction cost
The many advantages such as low, operating cost is low, easy to operate, high treating effect, processing and micro- pollution in all kinds of organic dirty (useless) water
Rapid development and application have been obtained in the restoration of the ecosystem of water body.
During artificial swamp organic pollutant removal and denitrogenation dephosphorizing, analyst of the microorganism as the system,
The main degradation task that carry pollutant.And Performance of Constructed Wetlands Substrates, as microbe carrier, the growth for microorganism provides
Stable depends on surface.The type and physicochemical property of filler directly determine the quality of its surface attached microbial growth, Yi Jiwei
Biomass and structure of community.Therefore, different wet land fillers creates different wetland microenvironments, passes through attached microbial
Bioactivity, and then influence the treatment effect of entire artificial wet land system.
For current research, the traditional artificial wet land filler such as granular fillers such as gravel, haydite, zeolite, flyash, hole
Gap rate is larger, but specific surface area is limited, and microorganism lacks enough attaching surfaces, so as to influence the growth and breeding of microorganism, makes
The effect of sewage disposal mesophytization is obtained to be restricted.And although the fillers specific surface area such as soil, sand grains is larger, porosity,
There are problems that substrate clogging again.Therefore, a kind of large specific surface area can be found, be easy to microorganism attachment, be not easy to plug simultaneously
New packing be the key that solve the problems, such as, and then existing technical bottleneck can be broken through, strengthened artificial wet land microbial action,
Improve treatment effeciency.
Invention content

Object degrades to organic pollution or nitrogen phosphorus.
Further, the gravel or zeolite of 30~40mm of bottom filling grain size φ of the filtering area, middle layer filling φ
The gravel or zeolite of 10~20mm, upper strata filling fine sand.The larger filler of grain size can be used in bottom, convenient for water distribution；Middle layer makes
With the smaller filler of grain size, be conducive to the solid interception of raising system, effectively alleviate substrate clogging；Upper strata (root system area) is selected
Fine sand, convenient for fixed root system of plant, is conducive to plant growth as filler.
The top planting plants of the filtering area, such as cyperus alternifolius or yellow leaf calamus.
Operation principle：The inner wall of filtering area is covered with basalt fiber, and central filler multiple filtration filler, the present invention will
Basalt fibre and traditional filtering filler, which combine, forms Novel filtration filler, on the one hand has good adsorption filtration to act on, together
When basalt fibre as good microbe carrier, be conducive to growth, the breeding of microorganism, give full play to microbial degradation work
With effectively removing the nutriments such as organic pollution and nitrogen phosphorus in water, waste water is flowed into from the bottom of filtering area, adsorbed
It filters, under the collective effect of microbial degradation, then the plant above filtered area is flowed out after further purifying.Wherein, basalt
Fiber has large specific surface area, is easy to that microorganism attachment, water resistant body impact load be big, filtering using natural basalt as raw material
Property well wait excellent characteristics.In order to further increase the area of microorganism attachment, basalt can be covered between every section of filtering area
Fibrous layer.
Advantageous effect：(1) basalt fibre has the specific surface area of bigger, higher machine compared to other fibrous materials
The advantages that tool intensity, stronger corrosion resistance and chemical stability, and derive from a wealth of sources, cheap, safe non-secondary pollution；
Basalt fibre compared to traditional wet land filler, more conducively microorganism aggregation, growth and breeding, so as to increase water treatment procedure
The concentration of middle microorganism increases substantially the efficiency of biochemical reaction；The present invention is creatively by basalt fibre and conventional filler
It is combined to form a kind of new packing, enough microorganism attaching surfaces is provided, enhance the degradation of wetland microorganism；(2)
The basalt fiber of the present invention is covered between the inner wall of filtering area, every section of filtering area so that basalt fibre has with sewage
The contact area of bigger, more fully time of contact are conducive to preferably play the sewage purification effect of basalt fibre；(3)
It is detachable that the present invention by upper and lower flange connection, by filtering divides into multistage, convenient for disassembly and assembly, is easy to replacement, has
The phenomenon that effect prevents artificial swamp substrate clogging.
