Description
Technical field
The present invention relates to a kind of preparation methods of modification biological charcoal, more specifically more particularly to a kind of alkali fusion flyash
The preparation method of modified pig manure charcoal.Present invention simultaneously relates to the applications of the modification biological charcoal.
Background technique
The discharge amount of dyeing waste water is very big, counts according to Europe, and the weight ratio of fabric and waste discharge is 1:150~1:200,
China is about 1:200~1:400.China's textile waste is the 6th of national discharged volume of industrial waste water, wherein 80% belongs to
Dyeing waste water.There are many processing method of dyeing waste water, mainly there is absorption, oxidation, UF membrane, flocculation, biodegrade etc..Absorption method
There is special status in field of waste water treatment with the characteristic that it can selectively be enriched with certain compounds.Active carbon is current
One of most effective adsorbent, but since its regeneration is relatively difficult, processing cost is higher, and application surface is narrow.Therefore a kind of warp is found
The effective adsorbent that helps becomes the key of current technological development.
According to United Nations Environment Programme, the crops planted in the world can provide about 2,000,000,000 t of all kinds of stalks every year, I
State's agricultural crop straw annual output is 700,000,000 t or so, arranges first of the world, converts into 3.53 hundred million t of tandard coal amount, account for whole world stalk total amount
30% or so.The annual agricultural straw resource amount in China accounts for about the nearly half of biomass resource amount.Agricultural crop straw is a kind of
Valuable renewable resource, but for a long time due to being influenced by consumption idea and life style, China's straw from village resource
Be completely in high consumption, high pollution, low output situation, considerable a part of agricultural crop straw thrown aside or burnt
It burns, does not obtain rational exploitation and utilization.According to investigations, China's straw utilization rate is about 33% at present, and wherein most does not add processing,
What is utilized after technical treatment only accounts for about 2.6%.Therefore, comprehensive utilization agricultural straw resource is for economizing on resources, protecting
Environment increases farmers' income, the sustainable development of agricultural is promoted all to have important practical significance.Straw charring technology has been me
It is environmental-friendly, high in technological content to provide one for the solution of state's stalk comprehensive utilization problem, and great market-oriented prospect is easy to handle
Method.
Charcoal has large specific surface area, porosity height, is rich in surface function as a kind of novel environmentally friendly repair materials
Group and stronger ion-exchange capacity have stronger application potential in removal water pollutant.However traditional biological charcoal absorption effect
Rate is low, and charcoal density is light, particle is small, and it is difficult to be separated by solid-liquid separation after absorption, be easy to cause secondary pollution, nor is conducive to
The regeneration and recycling of charcoal.Studies have shown that general composite material is better than homogenous material to the adsorption effect of pollutant.Cause
This, has at present had some scholars concern charcoal and other materials be applied in combination, using physics, chemical method by charcoal
It is combined with other materials and is prepared into the material with new capability, new construction, comprehensive performance is better than former composition material, can meet each
The different requirement of kind.The preparation of biological carbon composite be usually in biomass raw material add other materials (magnetic material,
Nano material, inorganic salts etc.), then composite material is prepared by high temperature pyrolysis.Charcoal compares table after being prepared into composite material
Area and aperture increases, surface functional group increase significantly improves the removal ability of pollutant, and is easy to be separated by solid-liquid separation after adsorbing.
But these composite materials are often expensive, the too small easy reunion of particle, and have certain toxicity, can reduce environmental microorganism
Type and quantity, these disadvantages limit the popularization and application of these composite materials.Currently, charcoal and its composite material are main
It is used to adsorb inorganic pollution in environment (such as heavy metal, fluorine) and organic pollutant (such as dyestuff, petroleum hydrocarbon, pesticide, antibiosis
Element etc.), study its adsorption effect and the mechanism of action.
