Description
Technical field
The invention belongs to field of inorganic nonmetallic material, and in particular to a kind of clean water sludge and diatomite preparation for dirt
The composite haydite of water process.
Background technique
Clean water sludge is the by-product that waterworks generates during purifying raw water, it mostlys come from filter back washing
The spoil disposal water of draining, sedimentation basin or clarifying basin.Since coagulant can be added in raw water precipitation process and soften 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 flowed through, based on inorganic constituents, the organic principles such as humus are less.Water purification at present
Sludge carries out landfill disposal primarily as waste, has both increased the production cost of waterworks, while also occupying a large amount of
Land resource, if improper conduct oneself well of clean water sludge is set, will be present to environment generate " secondary pollution " danger.Due to clean water sludge
Main component it is similar to conventional clay, therefore can use clean water sludge come replace clay carry out haydite preparation, this is to dirt
The minimizing of mud, innoxious, resource utilization have positive meaning.
Diatomite is a kind of biological siliceous rock of porous property, its main component SiO2, also contain 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 a large amount of orderly rows on diatomite shell
The micropore of column, therefore the pore volume of diatomite and specific surface area are very big, bulk density very little, have stronger absorption property and mistake
Filter ability is industrially commonly used in sewage treatment adsorbent, brewery's drainage, catalyst carrier etc..
At present for haydite there is no a proper definition, haydite belongs to a kind of light-weight aggregate, referring to artificial light
The definition gathered materials: haydite is that a kind of bulk density is less than 1100kg/m3, partial size has certain compression strength, surface in 5 ~ 20mm
There is the light-weight aggregate of the shell of ceramic or enamel.From the point of view of using functionally, 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 in current China, and shale materials need to exploit
Massif, this will lead to, and land resource aggravation is nervous and ecological environment is destroyed, therefore solid waste resource recovery is combined to utilize
There is important practical significance to develop novel ceramsite material just.
Have and some be utilized respectively sludge or diatomite to prepare the patent of invention of haydite: CN101148348A discloses one
The method of kind preparing haydite by sintering urban domestic sewage sludge, using 70% or more city sludge as primary raw material, flyash and clay are
Auxiliary material by drying, is pulverized and mixed, and obtains ceramic product using techniques such as mixing, extrusion forming, preheating, roastings.
CN102757255A discloses a kind of method for preparing light ceramic using clean water sludge and sewage sludge, with clean water sludge and dirt
Sewage sludge is primary raw material, is made using sintering technology.CN102491729A provides a kind of pretreated for micro-polluted water
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 are blended in balling-up on pelletizer, roast and are made pottery after drying raw meal
Grain, is cooled to after room temperature to be sieved and obtains haydite finished product.CN102775120A discloses a kind of diatomite porous pottery
Sodium hydroxide, waterglass and water are mixed with maturing agent according to 4:17:1:5 first by the preparation method of grain, this method；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
Haydite is made by rolling in the mass ratio investment stuffed dumplings machine of 3:1 in the spheric granules and shell powder got ready.CN104785203A is public
A kind of production method of diatomite water purification haydite of cloth, the haydite are passed through by diatomite and bentonite according to the mass ratio of 10:1
The processes such as ingredient, mud processed, granulation, drying, roasting are made, and haydite quality obtained is penetrating, have adsorptivity and filterability, favorably
In the attachment and procreation of microorganism.
Summary of the invention
It is an object of the invention to solve the problems, such as to generate secondary pollution to environment caused by water supply plant clean water sludge, simultaneously
The waste diatomite in conjunction with caused by brewery carries out solid waste resource recovery utilization, develops a kind of utilization clean water sludge and silicon
The composite haydite of diatomaceous earth preparation.From the point of view of the ingredient of sludge, the organic matter and energy content of sludge are higher, can satisfy firing
When basic demand, but the SiO in sludge2And Al2O3Content is lower, using only firing ceramsite by using sludge can not balling-up, because
This can be added with SiO2Diatomite as main component, while a small amount of calcium oxide is admixed as binder.
Technical solution: the invention discloses composite haydites prepared by a kind of clean water sludge and diatomite, include the feature that
It is raw materials used be 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.
The composite haydite of a kind of clean water sludge and diatomite preparation, it is characterised in that: raw materials used for water purification dirt
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 of a kind of clean water sludge and diatomite preparation, it is characterised in that: the diatom
Soil is used for one or more, the raw material use of the waste diatomite or ordinary silicon diatomaceous earth raw material of drainage for the brewery of recycling
When Retrieve beer factory drainage waste diatomite, need to carry out waste diatomite hydro-thermal method pretreatment: heating temperature is 160 DEG C, adds
The hot time is 6h, obtains the diatomite material for removing impurity.
The present invention have it is following the utility model has the advantages that
1. the blending amount of sludge is up to 60% or more, the fusing point of sludge is low, and mixing can be significantly reduced in the raising of sludge components
The fusing point of object, firing energy consumption reduces；Disposition clean water sludge can be handled on a large scale, realize the resource utilization of sludge, effectively
Solve the problems, such as secondary pollution present in the traditional landfill stabilization of water supply plant clean water sludge.
2. using diatomite as auxiliary material, a kind of the new of resource utilization is provided for the waste diatomite that brewery's drainage generates
Approach realizes the purpose of " treatment of wastes with processes of wastes against one another ".
3. composite haydite product strength made from is preferable, and pore structure is flourishing, and water absorption rate is high, and absorption property is good, is suitable for making
For material for water treatment.
It, can be by social benefit, ecological benefits 4. this method is practical advanced, easy to operate, low in cost, without secondary pollution
With economic benefit organic unity.
Detailed description of the invention
Fig. 1 is that the 1100 DEG C of sintering of clean water sludge and diatomite prepare composite haydite sample.
