Description
Technical field
The present invention relates to water-treatment technology field, be specifically related to a kind of water treatment filler based on modified biomass lime-ash and
Its preparation method.
Background technology
Saprobia membrane processing method be make antibacterial and the microorganism of mushroom one class and protozoacide, metazoa one class micro-
Type animal is attached to growth reproduction on filtrate or some carrier, and is formed on membranaceous biological sludge biomembrane.Participate in
The microorganism etc. that water processes needs constantly to draw nutrient substance necessary to it from the sewage of surrounding, including carbon source,
Nitrogen source etc..Carbon is the important substance of composition biological cell, participates in microorganism and the microfauna demand to carbon source that water processes
Relatively big, general as being not less than in terms of 5 by C/N.At present, industrial wastewater and part sanitary sewage phosphorus content are relatively low, it is impossible to ensure micro-life
Thing and the normal growth of microfauna and water treatment efficiency.The current solution of this problem is additional carbon, such as activated carbon,
Quartz sand, natural zeolite, ion exchange resin etc., but, additional carbon improves the cost that water processes largely.
Biomass lime-ash is lime-ash produced by the biomass fuels such as biomass electric power plant burning straw, timber, be current I
Produced main garbage in state's biomass electric power plant power generation process, general biomass lime-ash the most directly abandons, and adds that straw is sent out
The fast development of electricity industry, various places have been built a collection of power plant being energy main body with straw power generation, can have been produced big after its burning
The biomass lime-ash of amount.
Current substantial amounts of biomass lime-ash can not get reasonably disposing, and generally believes that its value is relatively low, regards it as
Garbage.To a certain extent can be by Institute of Micro-biology's profit yet with the organic matter of residual in imperfect combustion biomass lime-ash
With so that biological lime-ash has potential using value, therefore, if researching and developing new in terms of as the supplementary carbon source of sewage disposal
Biomass lime-ash is used in water treatment field by method, plays its due value, will have a very big significance.
Summary of the invention
The present invention provides a kind of water treatment filler based on modified biomass lime-ash and preparation method thereof, obtains carrying out carbon
Be derived to, there is the modified biomass treatment filler of large specific surface area and abundant surface functional group, to solve biology
Effective utilization of matter lime-ash, the problem simultaneously reducing cost of water treatment.
To achieve the above object of the invention, the technical solution used in the present invention is: a kind of water based on modified biomass lime-ash
Process the preparation method of filler, comprise the following steps: add the ratio of 0.6Kg～1Kg biomass lime-ash according to 1L mixed liquor, will
Biomass lime-ash joins in mixed liquor, then soaks under the conditions of 35～45 DEG C, rinses, and obtains based on modified biomass lime-ash
Water treatment filler；Described mixed liquor contain acetic acid that percent by volume is 0.8%～2% and molar concentration be 0.01mol/L～
The organic matter of 0.1 mol/L, surplus is water.
Preferably, biomass lime-ash is joined in mixed liquor, be mixed and stirred for uniformly, in order to mixed liquor and biomass
Lime-ash is fully contacted, and soaks, rinses under the conditions of 35～45 DEG C, is dried to obtain at graininess water based on modified biomass lime-ash
Reason filler, biomass lime-ash is lime-ash produced by firing biomass fuel.
In the present invention, the particle diameter of biomass lime-ash is 0.005mm～30mm；Biomass lime-ash is sieved, can obtain
Biomass lime-ash to different size particle diameter.The biomass lime-ash that the present invention processes can be applied directly as water treatment filler
In river course original sub-block, to COD, ammonia nitrogen, total phosphorus removal effect fine, clearance reaches 61.9%, 79.6%, 74% respectively；Also may be used
With use polyvinyl acetate and firming agent by being prepared as filler based on the microbe carrier of modified biomass lime-ash, at water
Reason.
In the present invention, biomass in straw, bark, rice husk, the timber any one or several.The present invention not only solves
Certainly effective Utilizing question of biomass lime-ash, and reduce the effect of cost of water treatment.
Preferably, the present invention carries out three rinsings under the conditions of 35～45 DEG C, every time after rinsing, according to biomass lime-ash with
The proportion requirement of mixed liquor changes mixed liquor；For the second time, it is both needed to soak ten minutes before third time rinsing so that mixed liquor is to biology
Matter lime-ash surface processes and modifies completely.
In the present invention, organic matter is selected from sucrose, sodium alginate, chitosan, Polyethylene Glycol, polyvinyl alcohol any one；Its
In, preferably sodium alginate.Acetic acid and organic matter is used to carry out composite modified to biomass lime-ash so that the ratio table of biomass lime-ash
Area increases and surface functional group increases, and is conducive to it to provide more attachment point and water Middle nutrition material to for microorganism
Chemisorbed.
Preferably, add the ratio of 0.6Kg～0.8Kg biomass lime-ash according to 1L mixed liquor, biomass lime-ash is added
In mixed liquor, then soak under the conditions of 40 DEG C, rinse, obtain water treatment filler based on modified biomass lime-ash；Described
Mixed liquor contains the acetic acid that percent by volume is 1.3%～1.5% and the organic matter that molar concentration is 0.08 mol/L, and surplus is
Water.
The invention also discloses the water treatment filler based on modified biomass lime-ash prepared according to above-mentioned preparation method.With
In river course original sub-block, to COD, ammonia nitrogen, total phosphorus removal effect fine, clearance reaches 61.9%, 79.6%, 74% respectively；COD、
Ammonia nitrogen water outlet all can reach " water environment quality standard " (GB3838-2002) III class standard；The clearance of total nitrogen is stablized
About 50%.Therefore the invention also discloses the application in water processes of the above-mentioned water treatment filler based on modified biomass lime-ash.
Compared with prior art, microbe carrier based on modified biomass lime-ash disclosed by the invention and preparation side thereof
Method, by using biomass electric power plant garbage biomass lime-ash as raw material, it is achieved that biomass electric power plant changing rejected material to useful resource, closes
Reason efficiently utilizes biomass lime-ash, had both solved problem of environmental pollution, and had reached again the effect that garbage effectively utilizes, for
Protecting ecology, Resource Recycling Utilization provide new method.
And, the present invention uses acetic acid and organic matter to carry out composite modified to biomass lime-ash so that biomass lime-ash
Specific surface area increases and surface functional group increases, and is conducive to it to provide more attachment point and water Middle nutrition thing to for microorganism
The chemisorbed of matter, thus beneficially growth of microorganism is bred, and form membranaceous biological sludge, reach effectively to process the effect of water body
Really.
Additionally, there is a certain amount of organic composition because of imperfect combustion in biomass starting material lime-ash, it is also possible to as carbon
Source is utilized by microorganism etc., reduces cost of water treatment, and the processing cost of former water per ton about declines 15～20%；And coordinate mixing
The modification of liquid inorganic agent, is greatly improved the product of the present invention treatment effect as water treatment agent, removes COD, ammonia nitrogen, total phosphorus
Except effect is fine, clearance reaches 61.9%, 79.6%, 74% respectively；COD, ammonia nitrogen water outlet all can reach " surface water environment quality mark
Accurate " (GB3838-2002) III class standard；The clearance of total nitrogen is stable about 50%.
