Description
Technical field
The invention belongs to water and process coagulation technology field, especially, relate to a kind of with Pericarpium Musae and oxidant for the most former
The preparation method of the oxidation modification Pericarpium Musae coagulant of material.
Background technology
Coagulation is by adding a certain amount of coagulant in water, to destroy in water with colloid and difficult hypostasis form existence
The stability of pollutant, promotes small float and colloidal solid to be condensed into larger particles and settle, reaches the mesh being separated from water
, make the process that water is purified.Owing to this process is simple, it is easy to accomplish, and there is versatility, therefore as a kind of important
Materilization freatment method, coagulation application in feedwater, industrial wastewater and sanitary wastewater process is quite varied, to every contamination index
Clearance the highest.And in coagulating treatment, focal spot techniques is coagulant.Coagulant is various in style, totally can be divided into inorganic,
Organic, microorganism and the big class of compound coagulant four.The research of coagulant in recent years always with at a low price, efficient, nontoxic for main body side
To, wherein natural organic high-molecular physical resources are abundant, cheap, degradable, nontoxic, are a kind of environmentally friendly products, and
For the former water that toxicity is less or nontoxic, the mud that water produces after processing can obtain with farmland reuse completely the most in recent years
The extensive concern of countries in the world water treatment field experts.On the other hand, along with solid refuse pollute become global problem it
After, utilize various inorganic, the study hotspot that organic coagulants is always water treatment agent field of solid waste research and development.Rice husk, rice straw, wheat
The agriculture and forestry organic waste materials such as stalk, corn stalk, Pericarppium arachidis hypogaeae, bagasse, fruit peel day by day expand in the range of application of water treatment field.In recent years
Coming, agricultural industrialization has carried out structural adjustment, promotes banana production to be significantly increased, and Pericarpium Musae is abandoned in a large number.Fructus Musae
Skin is the epidermis of Fructus Musae, and its weight accounts for about the 40% of fruit weight, and environment is caused a certain degree of latent by the Pericarpium Musae abandoned
In harm.Mainly include adsorptivity about Pericarpium Musae in the application of water treatment field and directly utilize two broad aspect.The most domestic
There are outward some patents utilized about Pericarpium Musae adsorptivity, such as: a kind of Pericarpium Musae modified activated carbon silicon for desulfurization and dedusting
Diatomaceous earth granule and preparation method thereof (CN201510191618.5), the system of a kind of pyromellitic acid anhydride modification Pericarpium Musae adsorbent
Standby (CN100406396C), utilizes Pericarpium Musae to prepare the method for ammonia nitrogen adsorbent and the application of ammonia nitrogen adsorbent
(CN201310168967.6) dye sorbent (CN201210121603.8) that, a kind of Pericarpium Musae is made.Wherein CN
100406396C provides a kind of with Pericarpium Musae as primary raw material, and the PMDA with PMDA as modifying agent changes
The preparation method of property Pericarpium Musae adsorbent；CN201310168967.6 is provided one and is only washed by the broken immersion of dehydration
Wash, utilize the method that Pericarpium Musae prepares ammonia nitrogen adsorbent；CN201210121603.8 provides a kind of employing fermentation method by Fructus Musae
Leather is for the method for dye sorbent.Also some are had to directly utilize the patent of Pericarpium Musae about water treatment procedure, such as both at home and abroad:
Utilize the method (CN201210009635.9) of Pericarpium Musae processing waste water containing chrome, utilize Pericarpium Musae to cook liquid and remove microcapsule in water body
The method (CN201110442551.X) of algae.Additionally, there is patent in terms of utilizing Pericarpium Musae to develop coagulant, " a kind of water processes
By the technology of preparing (201610245449.3) of Pericarpium Musae high-molecular coagulant adopting ", this patent have employed the " low temperature of 30 DEG C ~ 50 DEG C
Water extraction ", preparation is a kind of, and Pericarpium Musae utilization rate is higher, preparation cost is relatively low, water outlet pH value in the range of neutral or alkalescence, steady
Qualitative preferably, water treatment efficiency more excellent, especially to colourity, water process Pericarpium Musae high score that removal efficiency of heavy metals is higher
Sub-coagulant, although this coagulant is " water at low temperature lifting manipulation ", it also requires heating leaching, it addition, this coagulant needs to add anti-
Rotten agent is to extend its storage stability.
Summary of the invention
It is an object of the invention to overcome the weak point in above-mentioned technology, it is provided that a kind of stability preferably, low cost
