Description
Technical field
The present invention relates to a kind of grading method for the wet land filler for adding nano carrier material, category environmental protection technology neck
Domain.
Background technology
Artificial swamp is based on the ecological principle of natural wetland, artificially controls matrix, plant and microorganism etc.
The factor of catharsis is played, so as to realize the removal of dirty water pollutant, and popularization and application can be subject in Practical Project
New Type of Sewage Treatment System.Artificial swamp is generally divided into free water surface wetland.Current wetland, vertical-flow wetland, wherein vertical person who lives in exile
Work wetland gradually shows because of the features such as its floor space is relatively small, technique is advanced, energy-efficient, reduced investment, low operating cost
Reveal advantage.
Removal of the vertical-flow wetland system to nitrogen phosphorus and organic pollution in water, mainly utilize artificial dielectric, plant, micro- life
The physics of thing, chemistry, the triple synergies of biology, its mechanism of action include absorption, delay, filtering, redox, precipitation, micro-
Biological decomposition, conversion, plant masking, the effect of residue accumulated, water transpiration and Nutrient Absorption and all kinds of animals.Microorganism sends out
Substantial portion of removal effect, vertical-flow wetland filler surface and root system of plant have been waved by due to the growth of a large amount of microorganisms and
Biomembrane is formed, organic pollution is then removed by the absorption, assimilation and dissimilation of biomembrane, and research finds vertical current
For wetland to the disposal ability deficiency of organic pollution, this is relevant with vertical-flow wetland filler finite surface area.Other vertical current is wet
Ground is held very much due to the biomembrane that non-biodegradable suspension, the undegraded organic matter of the inorganic SS of non-degradable and part and aging come off
Wetland is easily blocked, this also reduces the water body purification effect of vertical-flow wetland to a certain extent.
Publication number CN104710015 discloses a kind of method for building vertical current constructed wetland packed bed, fills out from bottom to top
Filler in ABCD tetra- is filled, its particle diameter is 1-3 cm, and 15 ' 5 ' 5cm, 1cm, 1-3cm, its matrix has the hidden danger blocked, adjacent to fill out
Separated between the bed of material using the polyethylene pure material net of same network interface size, intensity is less than normal, and influences the water velocity of wetland；It is public
The number of opening 105776763 discloses a kind of new vertical artificial wetland composite substrate, be sequentially filled from inlet water to outlet water concrete,
Volcanic rock, anthracite, its particle diameter are 3-5cm, 1-3cm, 0.5-1cm, are downward vertical stream wetland, hydraulic detention time can not obtain
To guarantee；Publication number CN104649415 discloses a kind of artificial swamp matrix for adding microbe carrier stuffing, and matrix includes poly-
The soft microbial carrier material of ammoniacum, laying method is uniformly either laying or sealing laying afterwards, but polyurethane is soft micro-
Biological carrier materials synthesis belongs to organic material synthesis field, it is necessary to professional equipment and technology, and strict control condition, it is difficult to
High-volume synthesizes.
The vertical-flow wetland matrix used at present is because surface area per unit volume is limited, it is difficult to meets a large amount of microorganism growths
The needs of breeding generation biomembrane, and a certain degree of blockage problem be present, there are blockage problem difficulty or ease and quickly repair.
The content of the invention
The object of the present invention is to the defects of in order to overcome prior art, find a kind of simple and quick reparation wetland that solves and block up
A kind of plug problem, there is provided grading method for the wet land filler for adding nano carrier material.
Realize that technical scheme is as follows, a kind of grading method for the wet land filler for adding nano carrier material, adopt
Filled with bottom-up layering, be sequentially filled zeolite, nano modification haydite and vermiculite；Bottom-up packing material size diminishes successively；
The packed height of zeolite layer, nano modification haydite layer and vermiculite layers is 1;1:1, layering inserts is filled into layering screen；Layering screen
For the waterproof stainless steel mesh structure of surrounding, three kinds of filler layering screens are highly identical, but layering screen mesh aperture is different, wherein boiling
The layering screen mesh aperture of rock layers is 2.5 centimetres, and the layering screen mesh aperture of nano modification haydite layer is 1.2 centimetres, vermiculite layers
Layering mesh size be 0.3 centimetre.Layering screen mesh aperture is less than the particle diameter of corresponding filling filler.
The nano modification porous ceramic grain particle diameter is 1.5-2.5 centimetres, and the vermiculite particle diameter is 0.5-1 centimetres, the boiling
Stone particle diameter is 3-4 centimetres.
The nano modification porous ceramic grain material by haydite raw material clay with nanometer-sized Fe2O3 powder is sintered is made.
The invention has the advantages that the present invention is filled to Performance of Constructed Wetlands Substrates using bottom-up layering, it is bottom-up
The filling mode that packing material size diminishes successively can reduce the probability of upward vertical flow Wetland clogging, can when being backwashed
So that than being more smoothly rinsed to matrix, developing result is good.The present invention solves to be replaced and cleaned using layering screen formula filler to fill out
The problem of expecting complex operation.The mesh of layering screen is less than filling substrate particle diameter, will not be mutually mixed, advantageously reduce between matrix
The probability of Wetland clogging；Layering screen is bottom-up to be tapered into, and both can guarantee that the hydraulic detention time of vertical-flow wetland different layers,
The total processing time of vertical-flow wetland will not be increased again.The present invention is had than haydite in filler using nano modification porous ceramic grain
Bigger specific surface area, the microbial biomass of set is big, and bioaffinity is good；The surface of rough porous is advantageous to startup stage biology
The formation of film, while also make that water distribution is uniform, and fluid stable, microorganism colonization is fast, aging biomembrane is easy to fall off, and stability is high.
