Description
Technical field
The invention belongs to water-treatment technology field, and being related to a kind of natural polymer using banana skin and pomelo peel as raw material has
The preparation method of machine thing-microorganism integral type coagulant.
Background technology
Coagulation refers to pass through some way（Such as add chemical agent）Make what water-borne glue body particle and small suspension were assembled
Process, it is a kind of important unit operation in water and wastewater treatment technique, belongs to one of materilization freatment method of water.And coagulation
Agent, it is one of water treatment agent, is the main substance in coagulation process, its quality directly affects the quality of coagulation effect.Coagulation
Agent mainly includes machine coagulant and the major class of inorganic coagulant two.Wherein inorganic coagulant again include low molecule inorganic coagulant and
Macromolecule inorganic coagulant, organic coagulants again include synthetic organic polymer coagulant, natural organic high-molecular coagulant and
Microorganism coagulant.There is Inorganic whisker coagulant in addition, specifically segment, coagulant kind is numerous, from low molecule
To macromolecule, from single form to complex form, its development trend is cheap practical, non-toxic efficient.Inorganic coagulant price is just
Preferably, wide material sources, but may have potential adverse effect to human health and ecological environment.It is few to synthesize organic coagulants dosage,
Mud amount is few, and flocculation ability is more excellent, but side effect of the residual monomer to organism is more apparent, and its application is restricted.
Microbial flocculant is substantially nontoxic, easy to use in the absence of secondary pollution, although from its preparation, storing to use
Unstability is respectively provided with, but its characteristic and advantage expand a wide prospect for water technology, and its application pushes away
It is extensively still very tempting.And natural organic high-molecular is the food source of microorganism, therefore by microorganism and natural polymer knot
Altogether, in the case where preferably controlling synthesis condition, prepare natural organic matter-microorganism integral type coagulant and mixed for non-toxic efficient
The preparation field of solidifying agent is significant.Natural organic high-molecular coagulant derives from natural high molecular substance, such material
It is aboundresources, cheap, degradable, nontoxic, there is good environmental acceptance, and for the smaller or nontoxic raw water of toxicity,
Sludge caused by after water process completely can be with farmland reuse, therefore has obtained countries in the world water treatment field expert's in recent years
Extensive concern.Agriculture and forestry organic waste material belongs to natural organic high-molecular material, in the last few years, agriculture and forestry organic waste material is applied and led in water process
The scope in domain expands day by day, such as husk, rice straw, straw, cornstalk, peanut shell, bagasse, fruit peel etc..
Banana and shaddock belong to the main fruit of Perenniporia martius, and banana is very big in China south China yield, there is that " four is big
The title of fruit ".Shaddock is mainly distributed on China's southeastern coast, south China and southwest.In recent years due to agricultural industrialization
Structural adjustment, the yield of banana and shaddock is significantly increased, and China's banana total output reaches 11,790,000 tons within 2014, and shaddock is total
3,900,000 tons of yield.The pericarp of enormous amount can be produced after two kinds of fruit are edible, the wherein weight of banana skin can account for its fruit weight
40% or so of amount, and pomelo peel accounts for the 20% of whole shaddock gross weight, if caused pericarp is sold, its price is very low
Honest and clean, also significant component of banana skin and pomelo peel abandon in the environment as discarded object in addition, if do not dealt carefully with, meeting
A certain degree of negative effect is caused to environment.The Main Ingredients and Appearance of banana skin and pomelo peel includes the things such as polysaccharide and cellulose
Matter, these are all the functional components of coagulant.Mainly include adsorptivity on application of the banana skin in water treatment field at present
With directly utilizing two broad aspects.Than the patent if any some adsorptivities：A kind of banana skin modified activated carbon for desulfurization and dedusting
