Description
Technical field
The invention belongs to sewage treatment area, and in particular to a kind of attapulgite oil product decolorising agent of water process and its preparation
Method.
Background technology
Concave-convex clay rod product after processing is ideal adsorbent, food processing aid and food additives,
May replace activated carbon.It can not only decolourize, can also deodorant taste removal, removing heavy metals ion and carcinogen, also with certain choosing
Selecting property, this just provides convenience for production, and it can make deodorant for refrigerator, sewage-treating agent, household water filter, oil and fat refining and decolourize
Agent, effect is extremely obvious, can pharmaceutically make filler, carrier, additive, the binding agent of medicine.Use Concave-convex clay rod pair
Liquid glucose decolourizes that ten procedures can will be reduced to by 12 procedures of powder activity carbon purifying, and process cycle shortens 50 points
Clock, it is highly beneficial to developping production.With Concave-convex clay rod purify commerieal sugar, its color and luster, figure, concentration, content of reducing sugar,
PH value, sulfur dioxide ion concentration, chloride content, protein content, sugar cook temperature and calcium ions and magnesium ions content etc. reach existing
Row professional standard, saves desolventing technology expense 60% or so, and the filter cake after decolouring can make mixed fodder, reduce environmental pollution, reach
To comprehensive utilization.
Either in adsorption process, or in sewage disposal, Concave-convex clay rod can regenerate, and it consumes energy less,
It is highly beneficial to environmental protection.Concave-convex clay rod selection adsorption capacity size order be：Water>Alcohol>Acid>Aldehyde>Positive alkene>In
Property fat>Aromatic hydrocarbon>Cycloalkane>Alkane, straight-chain hydrocarbons>Cycloalkane>Alkane, straight-chain hydrocarbons adsorbs soon than branched-chain hydrocarbons, adsorptive selectivity
Play the role of to the decolouring of grease important.Also there is larger industrial value in other separation processes.
The conventional method of Water warfare is by flocculation, precipitation, filtering and is chemically treated, typically can effectively remove most of
Dirt and kill most of microbe, but can not very effectively remove such as hormone, agricultural chemicals, virus, toxin and heavy metal from
The class material such as son.These harmful substances are remained in water source, give people to cause harm.And Concave-convex clay rod can use contact or filtering
Technical finesse water, can eliminate these harmful substances.If making the recessed soil regeneration of absorption pollutant, can heat or be subject to chemical agent
Treatment.Therefore, application of the recessed soil in sewage disposal is very important to preserving the ecological environment, ensureing the health of the mankind, and
