Abstract
The invention relates to an organic sludge polarization treatment apparatus, and belongs to the sludge treatment field. The apparatus is used for pre-treatment before organic sludge pressure filtration, comprises a housing and a sludge overflowing channel in the housing, and is characterized in that the housing is provided with a polarization generation device, and the polarization generation device is one or a combination comprising devices selected from a metal ion generator, a magnetic field generator, a high voltage electrostatic generator, an ultrasonic wave generator and an ultraviolet ray generator. With the organic sludge polarization treatment apparatus of the present invention, the microorganisms in the organic sludge can be effectively killed, the form of the water molecules in the sludge can be changed, and the water content of the subsequent organic sludge can be subjected to pressure filtration to achieve 55-60%.
Description
Technical field
The invention belongs to field of sludge treatment, particularly relate to the press filtration process field of organic sludge.
Background technology
The sludge treatment of municipal sewage plant and ordinary method pass through sedimentation, press filtration delivers to refuse-burning plant burning electricity generation after becoming filter cake, but because the water content after sludge press filtration is up to 80%, before power plant's burning electricity generation, also need again baking dehydration further, just can enter stove burning to moisture content 50 ~ 60%.Transportation cost, processing cost all will increase considerably, therefore the mud in municipal sewage treatment, it is a scabrous problem of industry always, electricity power enterprise is reluctant to receive, and because water content is high, stacks in storage process, organic matter also can ferment, smelly, produce biogas contaminate environment, repeatedly there is municipal sludge methane generated by landfill in all parts of the country, causes the accident of personnel death.Why municipal waste water treatment sludge is by conventional pressure filter press filtration, although be forced into 1.2MPa, water content in filter cake is still between 78 ~ 82%, and other slip, as kaolin, carclazyte, calcium carbonate etc., under same filtration condition, the water content of filter cake just can reach 40 ~ 50%, mainly a large amount of in the mud microorganism of its reason is as the carrier of water molecules, the a large amount of water molecules of anchoring, water molecules is made to become cluster-shaped form to deposit (marine jellyfish is also like this), microorganism species is attached to again the organism surface in mud with cluster-shaped, this microbic mass, organism has good crystallized ability to water molecules, therefore make the water body in mud be difficult to press filtration to separate out.The sad filter of municipal sludge that Here it is, the combined symptoms place that cake moisture is high.Make sludge filtration performance boost, effective means wants killing microorganisms flora, such as: the method being used in mud slurry the unslaked lime mixing 5 ~ 15%, water body character acidity degree in mud is declined, change the ecological condition of microbial bacteria existence, microorganism active is declined or death, and then make cluster-shaped microorganism solution body, the reduction of cluster-shaped water molecules or disintegration are the cluster molecule that volume is little, or unit molecule water body, so just improve the permeability energy in mud, effectively can reduce the water content in sludge filter cake.In order to reduce the water ratio in mud, also people is had to add in mud to mix sterilization to fall agent, attempt the dehydration rate being improved mud by the germicidal action of medicament, but from result, not only sterilization effect is not obvious, only can kill part microorganism on a small quantity, therefore sludge dewatering efficiency is promoted not fairly obvious, under same working condition, only the moisture of sludge filter cake can be dropped to 70% from 80%, still can not meet the requirement of the sludge moisture content 60% needed for power plant, and add the cost that sterilant can increase by 20 ~ 30 yuan, mud per ton.Increase considerably the cost of sludge treatment.Also people is had in the industry by commercially available magnetic-type, electrostatic, ultraviolet line style Sterilizers, as the pre-process of family's water purification or tap water, but for the process of mud, because mud viscosity is high, microbe species is complicated, effective sterilizing cannot be carried out to mud, and because both character and field all exist larger difference, sludge treatment needs the large quantity of moisture in press filtration removal solids, so that the process of subsequent handling, and water treatment only need consider kill bacteria, those skilled in the art cannot take a hint from water treatment, therefore, the settled sludge in most city still continues to use the traditional method of landfill disposal, mud is suffer from the difficult matter having become the big city had, so far the high-efficiency dehydration of municipal sludge, become industry to pay close attention to and an insurmountable difficult problem, tackling key problem is still needed to overcome.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, provide and a kind ofly effectively kill the microorganism in organic sludge and change the form of water molecules in mud, the press filtration of follow-up organic sludge water ratio can be made to the organic sludge polarization treatment device of water ratio 55% ~ 60%.
For realizing the object of the invention, provide following technical scheme: a kind of organic sludge polarization treatment device, described device is used for the pre-treatment before organic sludge press filtration, comprise housing, mud flow channels in housing, it is characterized in that housing being provided with polarization generating unit, described polarization generating unit is metal ion generating unit, magnetic field generator, high-voltage electrostatic generator, ultrasonic generator, the one of ultraviolet ray generating apparatus or combination.
