Description
Technical field
Technical field:The present invention relates to inorganic non-metallic gel rubber material and specific resistance to filtration technical field, specifically relate to
And a kind of preparation method of utilization sludge incineration flying dust base low alkalinity geo-polymer.
Background technology
Due to urbanization and economy development requirement, China's quantity of wastewater effluent and treating capacity are in rising trend in recent years.By
The end of the year 2015, National urban sewage treatment plant 1.4 billion cubic meters of disposal ability/day, the annual accumulative sewage quantity that processes is up to 410.3 hundred million
Cubic meter.Meanwhile, sludge yield is continuously increased therewith, and the city sludge annual production of China in 2015 reaches 35,000,000 tons, increases on year-on-year basis
Long 16%, containing harmful substances such as a large amount of antibacterials, funguses, parasite and heavy metals in sludge, without the sludge that deals carefully with
Serious pollution can be caused, it is the effective process mode of sludge reduction that sludge incineration is processed；What sludge incineration was produced burns in a large number
Burning flying dust becomes new problem, and recycling is the effective way for solving the problem, such as prepares water treatment agent, and system
The construction materials such as brick, controlling the water circulation mud.
Geo-polymer have in construction material excellent mechanical performance and acid and alkali-resistance, fire resisting, high temperature resistant, fast solidifying and
Numerous excellent properties such as low stain, and geo-polymer is prepared without the need for calcining, power consumption is few.Prepare ground currently with trade waste
Matter polymer becomes new research direction, for example：Describe a kind of low lead crystal glass base matter to gather in patent 201310197482.X
The preparation method of compound, is that low lead crystal glass is smashed the powder for being ground to a diameter of 150-300 mesh, by itself and cement, quick lime
Alkali-activator, sodium sulfide and water are added with after Gypsum Fibrosum mix homogeneously, injection molding after slurry is stirred into, after 40-100 DEG C of maintenance 5-10h
The demoulding, then geo-polymer is obtained as curing box maintenance 24h, its 28d comprcssive strength can reach 15-30MPa；Patent
201310411112.1 using slag washing ball milling mud, concrete retarder and mineralizer production geology polymer.The method
Middle mineralizer needs to calcine 25-95min at 850-1100 DEG C, slag need to wash after solid-liquid separation, and need to dry and grinding
Deng processing；Patent 201410023136.4 describes a kind of preparation side of ultra-fine regenerated powder complex geological geopolymer gel material
Method, the method are made up of ultra-fine Waste brick regenerated powder, ultrafine slag powder, desulfurated plaster, sodium metasilicate and sodium hydroxide, its
In ultra-fine Waste brick regenerated powder specific surface area need to be selected to be not less than 1000m2/kg, 28d activity indexs be not less than 110% super
Thin slag powders；Patent 201310043067.9 discloses a kind of preparation method of omphacite geo-polymer, is by omphacite
Adding water reducer, pelletize being mixed after waterglass, injection molding, plus 30-90MPa pressure formings are 60- in 25-90 DEG C, humidity after the demoulding
Conserve under conditions of 90% and be obtained.Its Omphacite need to grind to form the granule of three kinds of ranks.In above-mentioned pertinent literature, most of all
Grinding, High Temperature Curing is needed, is partly related to high-temperature calcination and is added the preparation conditions such as 90MPa high intensity pressure, also have part
Raw material is had higher requirements, complex process, energy consumption are big, it is impossible to offer convenience to the recycling of garbage.
Content of the invention
Present invention aim to address the recycling of above-mentioned the deficiencies in the prior art and sludge incineration flying dust, there is provided
A kind of sludge incineration flying dust base low alkalinity geology polymer material and preparation method thereof, is the recycling treatment of sludge incineration flying dust
One new approach is provided.
The method is comprised the following steps：
Step 1：By sludge incineration flying dust and metakaolin with 1:1 mass ratio is sufficiently mixed and stirs, and obtains
Mixture is standby；
Step 2：Take account for mixture quality percentage ratio in step 1 for the NaOH of 2-10% and with account for compounding substances in step 1
Amount percentage ratio is 8%, and the modulus of industrial liquid waterglass is sufficiently mixed uniformly for 3.3 waterglass, makes alkali-activator standby.
Step 3：Raw material in step 1 is added in cement mortar mixer with the alkali-activator in step 2, and is added
It is the water of 35-50% with raw materials quality percentage ratio, stirs 5 minutes so as to mix homogeneously, make slurry.
Step 4：Slurry in step 3 is injected in cylindrical die, plus 11-14MPa pressure compactions, shaping and demoulding, room
Temperature places indoor lower maintenance 3-28 days, makes sludge incineration flying dust base low alkalinity geology polymer material.
Step 5：Intensity test is carried out to the geo-polymer in step 4 using Universal motor；Alkali-activated carbonatite in step 2
Agent addition is few, only accounts for the 10-18% of sludge incineration flying dust and metakaolin gross mass, and high compressive strength is equally obtained
Geo-polymer, has saved alkali-activator consumption, has greatlyd save production cost.
The primary chemical mass percent of sludge incineration flying dust is consisted of：SiO2:40.90%, Al2O3:21.80%,
Fe2O3:10.38%, CaO:6.67%, P2O5:6.58%.The primary chemical mass percent of described metakaolin is consisted of
