Compared with other domestic oily sludge treatment technologies, the method comprises the following steps:

1. compared with the domestic traditional oily sludge treatment method:

at present, various methods for treating the oily sludge with the water content of 80 percent are available in China; respectively as follows: technologies for implementing treatment and disposal of oily sludge include screening fluidization, conditioning, centrifugation, incineration, chemical hot washing, thermal desorption, composting, bioreactors, solvent extraction and the like, oily sludge generated in the domestic oilfield exploitation process generally adopts concentration dehydration, solidification, landfill treatment, catalytic cracking and the like, and the common defect of the existing treatment technologies is that heat energy contained in oily sludge with high economic value cannot be recycled; the invention has the technical innovation that the heat energy in the oily sludge can be utilized, a high-temperature rapid fermentation method is adopted to treat the oily sludge, the time is short, the treatment and fermentation time of the whole oily sludge is 8-12 hours, and the effect is good; the oily sludge with the water content of 80 percent can be manufactured into a regenerative clean fuel powder product of organic matters at one time, so that the national principle that sludge treatment and disposal are subject to the reduction of sludge from the source is realized; the stabilization, harmlessness, reduction and resource comprehensive utilization of the oily sludge are realized, the harm is turned into the benefit, the oily sludge with the water content of 80 percent does not need to be sent to a refuse landfill for landfill treatment, a large amount of land resources occupied by the oily sludge in the landfill process can be saved, and the treatment technologies such as landfill, incineration, blending combustion, solidification and the like are prioritized.

2. Compared with the pretreatment dehydration method of the oily sludge; wherein: the sludge concentration usually adopts two methods of gravity concentration and mechanical concentration, mechanical dehydration is carried out, and the commonly used mechanical sludge dehydration modes are a pressure filtration type and a centrifugal type, wherein the pressure filtration type mainly refers to a plate frame type and a belt type; a dehydration method, a concentration dehydration method;

the existing oily sludge treatment dehydration method mainly adopts a plate-frame mechanical dehydration method, and is characterized in that oily sludge with the water content of 80 percent conveyed by a sewage treatment plant is conveyed to a stacking yard, a plate-frame filter press is generally adopted for secondary dehydration treatment, and as the oily sludge with the water content of 80 percent has high viscosity, the dehydration can not be carried out by directly adopting the filter press, the oily sludge must pass through a sludge regulating water tank in the earlier stage of filter pressing, the oily sludge is subjected to alkene release degree regulation by using water to regulate the concentration of the oily sludge, and simultaneously a plurality of chemical agents are added into a regulating water tank, and after the demulsification treatment is carried out on the oily sludge by using the chemical agents, the oily sludge is conveyed to the filter press by using a water pump for filter pressing dehydration; the dewatered oily sludge is subjected to other process treatments, and simultaneously, a large amount of secondary sewage is generated in the filter pressing dewatering process, the sewage treatment is required, and the sewage is discharged after reaching the standard; a large amount of water resources are consumed in the treatment process, the treatment process does not accord with the regulation of national water-saving policy and the requirement of national environmental protection policy, the treatment time is too long, and the treatment cost is high.

The fly ash is selected as a raw material of a blender for treating the oil-containing sludge with the water content of 80 percent, and the adsorption effect, the flocculation precipitation and the filtration interception of the fly ash are mainly utilized; the adsorption effect of the fly ash comprises physical adsorption and chemical adsorption, wherein the physical adsorption means that the adsorption is generated between the fly ash and pollutant molecules of an adsorbate through intermolecular attraction, and the effect is determined by the porosity and the specific surface area of the fly ash; the chemical adsorption means that the fly ash contains a large amount of active ingredients of aluminum, iron and silicon, and can strongly adsorb most of colloid particles with negative electricity in the water contained in the oily sludge to generate flocculation; in addition, the fly ash contains coagulant aids, such as nickel, cobalt, arsenic, sodium, lithium and calcium, so that the sedimentation of the fly ash can be promoted; the chemical adsorption is characterized by strong selectivity, and under the common condition, the physical adsorption and the chemical adsorption exist at the same time, but the advantages of the physical adsorption and the chemical adsorption are different under different conditions of pH value and temperature, so that the adsorption performance of the fly ash is changed; in addition, as the fly ash is a mechanical mixture of various particles and has high porosity, when the moisture in the oily sludge passes through the fly ash, the fly ash can filter and retain all suspended matters;

the main influence factors of the fly ash in the process of treating the high water content of the oil-containing sludge include the following aspects: (1) The fly ash has small particle size fineness and large specific surface area, the finer the particle size of the fly ash is, the larger the specific surface area is, and the better the treatment effect on the water contained in the oil-containing sludge is; (2) chemical components of the fly ash: the content of active substances of SiO and A1O in the fly ash is higher, which is beneficial to chemical adsorption; (3) pH value of the solution: the pH value directly influences the treatment effect of water in the oily sludge, but the influence result of the pH value is related to the property of adsorbate; (4) temperature: research shows that the lower the temperature is, the higher the removal rate of harmful substances of the fly ash to the water in the oil-containing sludge is; (5) Properties of adsorbates: the solubility, molecular polarity, molecular weight and concentration of pollutants containing high water in the oily sludge all influence the water treatment effect of the oily sludge; the larger the molecular weight, the smaller the solubility, the better the treatment effect.

1. the chlorine dioxide has stronger adsorption and penetration capacity on cell walls, and releases atomic oxygen to oxidize enzyme containing sulfydryl in cells to play a role in sterilization;

2. the bleaching of chlorine dioxide is to release atomic oxygen and generate hypochlorite to decompose pigment; the bleaching agent is used as a bleaching agent to replace chlorine and chlorate, so the effect is more comprehensive;

3. the deodorization effect of chlorine dioxide is that chlorine dioxide can generate dehydration reaction with odor substances (such as H2S, -SOH, -NH 2) and make the odor substances quickly oxidized and converted into other substances, and simultaneously kill microorganisms without reacting with fatty acid; the chlorine dioxide has a safety effect, cyanide can be oxidized into carbon dioxide and nitrogen, namely 2ClO2+2CN =2CO2+ N2+2Cl, when the concentration of the cyanide is 3.0mg/L, the dosage of the chlorine dioxide is 5.0mg/L, and the removal rate of the cyanide is generally more than 85%; the advantages that a large number of foreign experimental studies show that chlorine dioxide is a safe and nontoxic disinfectant, has no 'three-cause' effect (carcinogenesis, teratogenicity and mutagenicity), and does not generate chlorination reaction with organic matters to generate organic chloride or other toxic substances which can generate 'three-cause' effect in the disinfection process; but because chlorine dioxide has extremely strong oxidizing power, the chlorine dioxide is not used at high concentration (> 500 ppm); when the concentration is lower than 100ppm, the composition does not have any influence on human bodies, including physiological and biochemical influences; has no sensitization to skin; therefore, chlorine dioxide is also internationally recognized as a safe, non-toxic, green sanitizer.
