Abstract
The invention relates to a method for comprehensively treating sludge and preparing ceramsite from the same and belongs to the technical field of sludge recycling reproduction. The method comprises the following steps of: mixing raw materials in proportion, homogenizing, pelletizing, dying, roasting and cooling. The raw materials to be mixed comprises the following components in percentage by weight: 10 to 20 percent of dyeing and finishing sludge, 60 to 70 percent of coal ash and residue, 5 to 10 percent of cullet, and 10 to 15 percent of primary soil generated from urban construction. The method has the advantages of energy source saving, environmental protection and reduction in the total cost of buildings by using waste as raw materials, good economic and social effects, simple process, low cost and suitability for industrial production. The produced ceramsite can be used for building structures, enclosing walls, bridges, roads, culverts and the like.
Description
Technical field
The present invention relates to a kind of mud comprehensive treating process and prepare the method for haydite, belong to mud and recycle the technical field of producing again.
Background technology
At present, haydite for building is raw materials for production with clay, shale etc. mainly, be made through metering, ageing, stirring, granulation, time brickkiln sinter process, it has the characteristics of high-strength light, energy-saving heat preserving, but, need to consume resources such as a large amount of clays and shale, vegetation destruction and damage simultaneously ploughed.Along with urbanization process is accelerated, national annual sludge produced by sewage treatment is up to 1,200 ten thousand tons, and with annual 15% speed increment, and a large amount of mud will produce secondary pollution as long as adopt measure such as land landfill to handle to underground water.Yet, contain a large amount of inorganic componentss in fact in the mud, mud as generations such as Sewage Plant or printing and dyeing mill or chemical plant contains large amount of organic, nutritive element and trace element in each, and more and more be subjected to people's attention as the alternate resources that turns waste into wealth, innoxious, the minimizing and the resource utilization principle that meet China's solid waste disposal again, vast potential for future development will be arranged, and therefore studying the recycling sludge treatment technology just seems very urgent.
Summary of the invention
At the deficiencies in the prior art, the object of the invention is to provide a kind of light weight, mechanical property is good, production cost is low mud comprehensive treating process and prepares the method for haydite.
For achieving the above object, technical scheme provided by the invention is specific as follows: a kind of mud comprehensive treating process and prepare the method for haydite, operate successively according to the following steps: proportioning raw materials, homogenizing, granulation, oven dry, roasting, cooling, it is characterized in that: the aforementioned base materials proportion raw material comprises the sedendary soil that printing and dyeing sludge, coal ash cinder, cullet, urban construction produce, and presses column weight amount per-cent and carry out proportioning:
Printing and dyeing sludge: 10%～20%;
Coal ash cinder: 60%～70%;
Cullet: 5%～10%;
The sedendary soil that urban construction produces: 10%～15%.
Described homogenization step is with the former abrasive lapping behind the homogenizing moisture, evenly stirs and one, and the grinding control coefficient is 350～400 orders, and synthetic raw material water content is controlled at 30%～40%.
In the described baking step, the operation of equipment temperature is controlled at 100～200 ℃.
In the described calcination steps, the operation of equipment temperature is controlled at 1200～1250 ℃.
In the described proportioning raw materials, printing and dyeing sludge is 15% of a gross weight, and the coal ash cinder is 70% of a gross weight, and cullet is 5% of a gross weight, and the sedendary soil that urban construction produces is 10% of gross weight.
Beneficial effect of the present invention is: utilize waste material to make raw material, economize on resources, be beneficial to environmental protection, the buildings comprehensive cost is also reduced, have good economic benefit and social benefit; Technology is simple, with low cost, is suitable for suitability for industrialized production; It is first-class that haydite after making can be used for building structure, retaining wall, bridge, highway and culvert.
Below in conjunction with description of drawings and specific embodiment technical scheme of the present invention is described in further detail.
