It is as follows with domestic other sludge disposal technology comparisons:
1, it is compared with traditional method for sludge treatment:
Currently, processing method of the China to the sludge of moisture content 80%, it may be said that be it is multifarious, there are many multiplicity sludge at Reason method;Wherein: have landfill, burn, mix burning, system fertilizer, solidification etc.;But the early period of these processing methods, it is necessary to moisture content After 80% sludge will carry out primary dewatering processing again, the moisture content for reaching national regulation can be filled below 60%, It burns, mix burning;Landfill needs to occupy a large amount of land resource, can also contaminated soil and underground water source, be easy to produce new secondary Pollution, burning, blending and burning technology are all immature, and burning disposal is at high cost, and there are no successful cases in the whole nation at present.
2, compared with mud dewatering method;Wherein: having press-filtering dehydration method, thickening method;
Current Treatment of Sludge dewatering, mainly press-filtering dehydration method are the moisture content 80% for carrying out sewage treatment plant's transport Sludge be sent into and stack field, second dehydration processing is generally carried out using filter press again, since the sludge viscosity of moisture content 80% is big, Directlying adopt filter press dehydration can not carry out at all, it is necessary in filters pressing early period, first have to sludge passing through sludge conditioning pond, Sludge is subjected to alkene degree of releasing conditioning of mud concentration with water, while also to add a variety of organic and inorganic chemical drugs in balancing tank Agent after carrying out demulsification processing to sludge using chemical agent, then is sent into filter press with water pump and carries out filter-press dehydration;It is dewatered Sludge carries out other process again, while a large amount of sewage is also created during filter-press dehydration, needs to carry out sewage again Processing, is discharged again after up to standard;A large amount of water resource is consumed during processing, do not meet the rule of national water conservation policy It is fixed, the environmental protection policy requirement of national regulation is not met yet, overlong time is handled, processing cost is high.
3, compared with traditional sludge composting method;
Traditional sludge composting production mainly carries out zymotechnique using the method for heap body, cannot be made when doing fermentation heap body Too small too short, too small to will affect fermentation, height is generally at 1~1.5 meter, 2 meters of width or so, heap body of the length at 2~4 meters or more Ferment effect is preferable;And punch and ventilate on heap top, finally the covering of heap body is touched with ground with plastic cloth, compost fermentation auxiliary agent It is oxygen-consuming microorganism, so oxygen supply measure should be increased during the fermentation, accomplishes to mix thoroughly, duty is turned over, ventilating is advisable, it otherwise can be because Material fermentation effect is influenced for anaerobic fermentation;Generally after sludge is accumulated 48 hours, it is primary that third day starts turning, ordinary circumstance Fermentation can be completed lower turning 3~5 times, the completion that can ferment in summer normal one week or so needs multiple turning, heap temperature is not Height, killing disease pest ovum, weeds seed are not thorough, and winter needs 30 to 60 days, and effect is poor, and occupied ground is big, and the compost time is long.
The present invention selects cinder from refuse incineration powder as the raw material of the blender of high-moisture percentage in processing sludge, mainly Utilize chemical active ingredient (SiO of the cinder from refuse incineration after wearing into fine powder2And Al2O3), cinder from refuse incineration, It is a kind of waste residue that house refuse generates in high temperature incineration power generation process, as house refuse is during high-temp combustion, companion As the organic substance in porosity carbon granule is completely burned the raising with temperature, it is dehydrated the minerals in rubbish, divides Solution, oxidation become inorganic oxide substance, and cinder particle at this time becomes porous vitreum, although its form is generally still tieed up Hold identical as porous carbon granule, but specific surface area is significantly less than porous carbon granule;Porous vitreum is set gradually to melt molten contraction and be formed Particle, porosity constantly reduce, and circularity is continuously improved, and partial size constantly becomes smaller, and are finally changed into a density by porous vitreum Higher, the lesser closely knit sphere of partial size, specific grain surface product fall to minimum;Different grain size and the soot particle of density have significant Feature in terms of chemistry and mineralogy, little particle is generally more more glassy than bulky grain and chemical activity;Wherein incinerator ash SiO in slag2Content are as follows: 35.63% ,~42.56%;Al2O3Content are as follows: 12.50%~18.67%;Cinder from refuse incineration is divided It is the powder less than 0.045mm that its fineness partial size, which is made, after choosing, magnetic separation removal old metal, drying, crushing, milling, screening;Due to Suction-operated and flocculated effect of the cinder from refuse incineration after fine powder is made all increase;
Cinder from refuse incineration powder, the suction-operated in the harmonic process of processing moisture percentage in sewage sludge includes physical absorption and chemistry Absorption;Physical absorption refers between cinder from refuse incineration powder and the contaminant molecule of adsorbate, generates suction by intermolecular attraction Attached, this effect is determined by the porosity and specific surface area of cinder from refuse incineration powder;Chemisorption refers to that rubbish is burnt Ashing ground-slag material there are a large amount of aluminium, iron, silicon active constituent, the middle electronegative colloidal particles of majority aqueous to sludge are able to carry out Strong absorption generates flocculation;Along in cinder from refuse incineration powder also contain flocculation aid ingredient, as nickel (Ni), Cobalt (C0), arsenic (As), sodium (Na), lithium (Li), calcium (Ca), can promote its sedimentation;Chemisorption feature is that selectivity is strong, logical In normal situation, physical absorption and chemisorption are existed simultaneously, but the pH value of different condition, at a temperature of the advantage that embodies It has nothing in common with each other, cinder from refuse incineration powder absorption property is caused to change;In addition, since cinder from refuse incineration powder is a variety of particles Mechanical impurity, porosity is larger, therefore, sludge high-moisture percentage pass through cinder from refuse incineration powder when, incinerator ash Ground-slag material can retain whole suspended matters.
Major influence factors of the cinder from refuse incineration powder in reconciliation sludge during high-moisture percentage have: (1) rubbish The particle diameter fineness of incineration residue powder is small and large specific surface area, the partial size of cinder from refuse incineration powder is thinner, specific surface area more Greatly, better to the reconciliation effect of moisture content in sludge;(2) chemical constituent of cinder from refuse incineration powder: cinder from refuse incineration The activity substance content of SiO and A1O is higher in powder, is conducive to chemisorption;(3) pH value: pH value directly affects the place of sludge Effect is managed, but the influence result of pH value is related with the property of adsorbate;(4) temperature: temperature is lower, cinder from refuse incineration powder pair The harmful substance removal rate of sludge higher moisture is higher;(5) property of adsorbate: contained humidity polluter is molten in sludge Xie Du, molecular polarity, molecular size range, concentration etc. all have an impact to the treatment effect of contained humidity in sludge;Molecular weight is bigger, Solubility is smaller, and treatment effect is better.
The present invention selects chlorine dioxide as the disinfection in Treatment of Sludge, deodorization, fungicide, and chlorine dioxide is by sodium chlorate With sulfuric acid and methanol effect or sodium chlorate and sulfur dioxide act on and made of product;It is using chlorate as raw material, in sulfuric acid Chlorine dioxide made of being restored in medium;Has the function of sterilization, bleaching, deodorization, disinfection, fresh-keeping;The mechanism of action is mainly oxygen The electronic structure of change effect, Chlorine Dioxide Molecules is in undersaturated condition, and outer layer shares 19 electronics, is made with strong oxidation With, mainly the atomic radical (such as enzyme and sulfide containing sulfydryl, chloride) rich in electronics (or supplied for electronic) is attacked, Electronics is robbed by force, makes the substance for losing activity and changing property, to reach its purpose;
1, bactericidal effect, chlorine dioxide have stronger absorption and penetration capacity to cell wall, release elemental oxygen and contain intracellular The oxydasis of sulfydryl plays bactericidal effect;
2, blanching effect, the bleaching of chlorine dioxide are to reach the mesh of decomposition pigment by releasing elemental oxygen and generation hypochlorite 's;Bleaching agent is made instead of chlorine, chlorate using it, thus effect is more comprehensively;
3, deodorization, the deodorization of chlorine dioxide are because it dehydration can occur with smell substance (such as H2S ,-SOH ,-NH2) instead So that smell substance rapid oxidation is converted into other substances, at the same kill microorganism without with fatty acid response;Safety effect, Chlorine dioxide can be by cyanide oxidation at carbon dioxide and nitrogen, it may be assumed that 2ClO2+2CN=2CO2+N2+2Cl is dense when cyanide Degree is 3.0mg/L, and the dosage of chlorine dioxide is 5.0mg/L, and the removal rate of cyanide is generally all 85% or more;Advantage, state Outer a large amount of experimental study shows that chlorine dioxide is safe and nontoxic disinfectant, and without " three cause " effect, (carcinogenic, teratogenesis, cause are prominent Become), while also chlorination not occurring with organic matter in disinfecting process and generating the organic chloride that can produce " three-induced effect " Or other toxic substances;But since chlorine dioxide has extremely strong oxidability, should be avoided at high concentrations (> 500ppm) makes With;When using concentration be lower than 100ppm or less when any influence will not be generated to human body, including Physiology and biochemistry in terms of influence; To skin also without any sensitization;Therefore, chlorine dioxide is also known as safe and nontoxic green disinfectant sterilization in the world Agent.
