Description
Technical field
The invention belongs to the processing of sludge to recycle field, and in particular to a kind of low energy consumption waterworks sludge miniaturation method.
Background technology
Waterworks sludge is as the accessory substance during Water purification, mainly by iron-aluminium oxide（Hydroxide）Formed with silt present in raw water.While running water produces, substantial amounts of sludge can be produced.At present, the main disposal options of waterworks sludge are landfills, although this method handling process is simple, still suffer from the shortcomings that certain, first, needing to take substantial amounts of landfill place, spend higher freight；Second, waterworks sludge causes the waste of resource as a kind of material of potential recoverable, the processing mode of landfill.How rationally to dispose and have become using waterworks sludge one of environmentally friendly hot issue paid close attention to jointly the world today.
Iron and aluminium in waterworks sludge mainly exist in the form of unformed, have larger micro pore volume and specific surface area, can do sorbing material.And reclaim waterworks sludge as adsorbent also increasingly to be paid attention to, as the patent of Application No. 201310205397.3 discloses a kind of method for removing phosphorus in town sewage using waterworks sludge；The patent of Application No. 201310502872.3 discloses a kind of absorption column method that hydrogen sulfide in waste water is removed using waterworks sludge；The method that the patent of Application No. 201310205380.8 discloses a kind of residual clay standby heavy metal absorbent of batch-type activation water treatment plant；The patent of Application No. 201310308975.6 discloses a kind of preparation method of the useless mud ammonia nitrogen adsorbent of modified water purification.At present, when making adsorbent using waterworks sludge, be mostly directly by waterworks sludge air-dry it is broken after utilize its powder form.But there are shortcomings in powdered waterworks sludge, such as when using powdered waterworks sludge processing waste water, subsequently need to carry out separation of solid and liquid；When doing adsorption column using powdered waterworks sludge, it is easy to block, increases water conservancy load；And powdered waterworks sludge is not easily recycled.These shortcomings all limit widely using for waterworks sludge, therefore, the inexorable trend that waterworks sludge granulating will be utilized as following sludge.
At present, just from the point of view of disclosed patent, the method for existing some waterworks sludges granulating, such as the patent of Application No. 201210243441.5 disclose the method that light ceramic is prepared using copper water-supply pipe and sewage sludge；The patent of Application No. 201310192673.7 discloses purple sand ceramics product fired using alum sludge and preparation method thereof；The patent of Application No. 201210573197.9 discloses a kind of method that environment friendly pervious brick is prepared using copper water-supply pipe.But these methods all use high-temperature calcination during granulation, consume the substantial amounts of energy, add granulating cost.Therefore, the waterworks sludge prilling process for finding a kind of low energy consumption is urgent problem to be solved in current Granulation of Sludge.
The content of the invention
The problem of in order to overcome above technology to exist, the present invention is intended to provide a kind of energy consumption is low, not sintered waterworks sludge miniaturation method, by the way that waterworks sludge desiccation is crushed, adds a certain amount of auxiliary material and be granulated, by the maintenance in later stage, realize granular sludge.
A kind of low energy consumption waterworks sludge miniaturation method proposed by the present invention, is comprised the following steps that：
（1）The pretreatment of raw material：By waterworks sludge nature desiccation, crush, cross 100 mesh sieves；
（2）Dispensing：The waterworks sludge of pretreatment, cement are subjected to ball milling mixing in ball mill, obtain compound, the mass ratio of wherein waterworks sludge and cement is：1:(0.5-2)；
（3）Granulating and forming：Compound is placed in nodulizer, sprays appropriate water, is granulated balling-up, screening obtains the product that particle diameter is 0.8-1.2mm；
（4）Maintenance：It is 20 DEG C that particle, which is put into standard curing box in temperature, and relative humidity conserves 28d under conditions of being 90%, that is, obtains unburned copper water-supply pipe particle.
Preferably, step（2）Described in cement be 42.5 grades Portland cement.
Preferably, step（2）Described in the ball milling mixing time be 4h.
Preferably, step（3）Described in water quality be material gross mass 10%.
The advantages of present invention obtains and beneficial effect are：
（1）A kind of waterworks sludge miniaturation method is provided, this method provides a kind of new way for the processing disposal of copper water-supply pipe；
（2）By granular sludge, its actual engineering application value is improved；
（3）Granulating is carried out using non-sintered method, has the characteristics of energy consumption is low, technique is simple, efficiency high；
（4）The recycling of copper water-supply pipe is realized, resulting mud granule, there is certain intensity and specific surface area, available for construction material, soil remediation material, sorbing material and water treatment filter material etc..Meet the theory of recycling economy, there is good economy and environmental benefit.
