Description
Technical field
The invention belongs to field of inorganic nonmetallic material, and in particular to a kind of clean water sludge and diatomite prepare for dirt
The composite haydite of water process.
Background technology
Clean water sludge is the accessory substance that waterworks is produced during purification raw water, and it mostlys come from filter back washing
The spoil disposal water of draining, sedimentation basin or depositing reservoir.Due to coagulant being added in raw water precipitation process and softens medicament, in sludge
Corresponding oxide and hydroxide, such as Fe can be contained2O3、SiO2、CaO、Mg(OH)2Deng clean water sludge almost contains raw water
The all elements and compound of the surface layer for being flowed through, based on inorganic constituents, the organic principle such as humus is less.Current water purification
Sludge carries out landfill disposal primarily as discarded object, both increased the production cost of waterworks, while also occupying a large amount of
Land resource, if improper the conducting oneself well of clean water sludge is put, there will be to environment produce " secondary pollution " danger.Due to clean water sludge
Main component it is similar to conventional clay, therefore clay can be replaced using clean water sludge to carry out the preparation of haydite, this is to dirt
The minimizing of mud, innoxious, recycling have positive meaning.
Diatomite is a kind of biological siliceous rock of porous property, its main component SiO2, also containing a small amount of iron calcium
The metal oxides such as magnalium, usual SiO2The more high then diatomite performance of content is better.There are on diatomite housing a large amount of rows in order
The micropore of row, therefore diatomaceous pore volume and specific surface area very big, bulk density very little, with stronger absorption property and mistake
Filter ability, is industrially commonly used in the aspects such as sewage disposal adsorbent, brewery's drainage, catalyst carrier.
At present for haydite does not have a proper definition, haydite belongs to a kind of light-weight aggregate, with reference to artificial light
The definition gathered materials：Haydite is that a kind of bulk density is less than 1100kg/m3, particle diameter possesses certain compression strength, surface in 5 ~ 20mm
There is the light-weight aggregate of the shell of ceramic or enamel.In view of using function, haydite is broadly divided into building ceramsite and water process pottery
Grain.Based on leca and haydites of book structure, clay material has drawn from arable land the haydite of current China, and shale materials need to exploit
Massif, this can cause, and land resource aggravation is nervous and ecological environment is destroyed, therefore utilizes with reference to solid waste resource recovery
Just there is important practical significance to develop novel ceramsite material.
Have some to be utilized respectively sludge or diatomite to prepare the patent of invention of haydite：CN101148348A discloses one
The method for planting preparing haydite by sintering urban domestic sewage sludge, with more than 70% city sludge as primary raw material, flyash and clay are
Auxiliary material, through drying, is pulverized and mixed, then obtains ceramic product through techniques such as batch mixing, extrusion forming, preheating, roastings.
CN102757255A discloses a kind of method that utilization clean water sludge prepares light ceramic with sewage sludge, with clean water sludge and dirt
Sewage sludge is primary raw material, is made using sintering technology.CN102491729A provide it is a kind of for micro-polluted water pretreatment
The preparation method of boiling water copper water-supply pipe haydite, the haydite is by a certain proportion of water supply plant dewatered sludge, modified zeolite powder and foaming
Agent in mass ratio 50 ~ 60%, 35% ~ 49%, 1% ~ 5% ratio uniform is blended in balling-up on comminutor, and roasting after drying raw meal is made pottery
Grain, is sieved after being cooled to room temperature and is obtained haydite finished product.CN102775120A discloses a kind of diatomite porous pottery
The preparation method of grain, the method is first by NaOH, waterglass and water according to 4：17:1:5 are mixed with maturing agent；According to matter
Amount 45% ~ 55% diatomite of percentage, 10% ~ 18% bentonite, 35% ~ 38% water uniformly mix, and are pressed into spheric granules；According to quality
Percentage is equipped with 20% ~ 30% flyash, 20% ~ 30% diatomite, 50% maturing agent and is uniformly mixed with shell powder；By above-mentioned system
The spheric granules got ready and shell powder are by 3:Roll in 1 mass ratio input stuffed dumplings machine and haydite is obtained.CN104785203A is public
A kind of production method of diatomite water purification haydite of cloth, the haydite is by diatomite and bentonite according to 10:1 mass ratio is passed through
The operations such as dispensing, mud processed, granulation, drying, roasting are made, and obtained haydite quality is penetrating, possesses adsorptivity and filterability, favorably
In the attachment and procreation of microorganism.
The content of the invention
It is an object of the invention to solve the problems, such as to producing secondary pollution to environment caused by water supply plant clean water sludge, while
Waste diatomite with reference to produced by brewery carries out solid waste resource recovery utilization, develops one kind using clean water sludge and silicon
Composite haydite prepared by diatomaceous earth.From the point of view of the composition of sludge, the organic matter and energy content of sludge is higher, can meet firing
When basic demand, but the SiO in sludge2And Al2O3Content is relatively low, individually with firing ceramsite by using sludge can not balling-up, because
This can be added with SiO2For the diatomite of main component, while a small amount of calcium oxide of blending is used as binding agent.
Technical scheme：The invention discloses composite haydite prepared by a kind of clean water sludge and diatomite, including following characteristics：
It is raw materials used for clean water sludge, diatomite, calcium oxide, mixing according to a certain percentage, balling-up, drying, 400 DEG C of preheating 25min,
900 ~ 1200 DEG C of roasting 30min are formed.
Composite haydite prepared by a kind of described clean water sludge and diatomite, it is characterised in that：It is raw materials used for water purification it is dirty
Mud, diatomite, calcium oxide, the ratio by mass：60 ~ 90 parts of clean water sludge；20 ~ 30 parts of diatomite；Calcium oxide 10 ~ 20
Part.
Further, the composite haydite that prepared by a kind of described clean water sludge and diatomite, it is characterised in that：The diatom
Soil is one or more of waste diatomite or ordinary silicon diatomaceous earth raw material that the brewery for reclaiming is used for drainage, and the raw material is adopted
During Retrieve beer factory drainage waste diatomite, need to carry out hydro-thermal method pretreatment to waste diatomite：Heating-up temperature is 160 DEG C, adds
The hot time is 6h, obtains the diatomite material for removing impurity.
The present invention has following beneficial effect：
1. the blending amount of sludge is up to more than 60%, and the fusing point of sludge is low, and the raising of sludge components can significantly reduce mixture
Fusing point, firing energy consumption reduces；Disposal clean water sludge can be processed on a large scale, realize the recycling of sludge, effectively solving
Secondary pollution problem existing for the traditional landfill stabilization of water supply plant clean water sludge.
2., with diatomite as auxiliary material, the waste diatomite produced for brewery's drainage provides a kind of the new of recycling
Approach, realizes the purpose of " treatment of wastes with processes of wastes against one another ".
3. preferably, pore structure is flourishing for composite haydite product strength obtained in, and water absorption rate is high, and absorption property is good, suitable to make
For material for water treatment.
