Description
Technical field
The utility model relates to the environmental protection running gear, especially relates to the dispose of sewage portable mud electric osmose dewatering unit of mud of factory of a kind of mobile employing mechanical presses and electric osmose dehydration technique.
Background technology
The generation of waste water is the inevitable fact.For fear of any pollution, waste water must be handled to reach environmental standard, and a large amount of mud that wastewater treatment produces must be handled by the method for soil fertilizing (being used for agricultural), burning or garbage loading embeading.The increase of world population, Economic development and more and more stricter mud discharging system have all applied huge pressure to the city industrial effluent treatment plant that has stable political situation.
The problem of sludge treatment existence at present:
1. only the volume through concentration is still bigger for mud, and transportation is inconvenient.
2. owing to trade effluent proportion in the municipal effluent is bigger, heavy metal content is more, and quite a few heavy metal is transferred in the mud after treatment, causes the sludge heavy-metal content of Sewage Plant higher; The harmless treatment that mud is stablized and deinsectization ovum etc. is necessary, after directly being applied to the farmland, objectionable impuritiess such as a large amount of pathogenic bacterias in the mud and parasitic ovum are transferred on farmland and the crop, not only may pollute, influence plant growth and human beings'health, and may assemble the harm that causes the environmental health aspect because of mosquitos and flies to soil.
3. in recent years, because the suburbs and counties under the jurisdiction of a large city peasant gets used to using chemical fertilizer more, and the restriction that is subjected to existing fertilizing method, cause mud not smooth as the fertile outlet of farming; And China's southern area rainfall is abundant, owing to the demand of farmland to the higher mud of water ratio falls sharply, also causes mud outward transport difficulty one to rainy season, and the completely present situation for suffering from of mud often appears in Sewage Plant.Therefore, this just may produce two kinds of adverse consequencess, and first Sewage Plant can only reduce normal sludge discharge or part mud is back to treatment system again, thereby has influenced the normal operation of Sewage Plant; It two is that part mud may overflow be gone into water body, causes the secondary to water body to dye.
Traditional sewage disposal mainly realizes by the mechanical dehydration mode, and by applying high pressure, use a large amount of condensing and flocculating polymer, the mechanical dehydration method can be relatively easily and extracted free water effectively.Yet a lot of dewatered sludges still have higher water content (65-85%), and residuary water mainly is made up of planar water.That is to say, be subjected to physics and chemical action to be bundled in planar water on the mud solid-state molecular, is to remove by traditional mechanical dehydration method.
Up to the present, the technology that can be used for sludge treatment can't reach the high speed dewatering and the efficient sanitary measure of mud.Meanwhile, energy consumption is skyrocketed, and the mud generation increases fast, and treatment process lacks; These have all caused sludge treatment running cost to increase uncontrollablely, make the owner of waste water treatment plant and the sludge treatment new device that the urgent searching of operator can reduce cost and be in debt.
Summary of the invention
The purpose of this utility model is to provide a kind of liquid sludge that is movable to produce ground, and can utilize the osmosis principle or utilize simultaneously mechanical pressure be used for reach effective dehydration, make liquid sludge reach the portable mud electric osmose dewatering unit of high ridity.
The purpose of this utility model is achieved in that the utility model comprises running gear main body and the mud electric osmose dewatering unit that is installed in the running gear main body loading railway carriage or compartment, one end of described electric osmose dewatering unit is provided with the mud inlet that mud for liquid enters, below along the mud inlet is provided with the filtration belt that is covered with wire netting and surface-coated insulation water-absorbing material, filter belt wire netting can with the negative electrode conducting of direct supply, the two ends of filtering belt are equipped with driving roll, driving roll can drive and filter belt translation forward, the sky of filtering belt is provided with a conductive pressing plate in parallel at least, conductive pressing plate be connected with mud electric osmose dewatering unit by pillar and can with the anode conducting of direct supply; The other end of described electric osmose dewatering unit is provided with mud discharging mouth, and mud discharging mouth is attached with near the extrusion roll that filters belt, and the extrusion roll below is equipped with the rising pipe that is provided with captation.Liquid sludge is after the mud inlet of electric osmose dewatering unit enters, be tiled in to filter on the belt and follow the filtration belt and between filtration belt and conductive pressing plate, move forward, in when work because the anode conducting of conductive pressing plate and direct supply, and be covered with in the filtration belt wire netting and with the negative electrode conducting of direct supply, liquid sludge closely places filters between belt and the conductive pressing plate, electric current will make the positively charged ion in the liquid sludge transfer to wire netting (negative electrode) from conductive pressing plate (anode) this moment, by viscid activity, positively charged ion in the liquid sludge will carry water molecules and move to negative electrode, water molecules is adsorbed on the insulation water-absorbing material that filters belt surface on the belt filtering, final exsiccant mud is discharged from mud discharging mouth, the filtration belt that is adsorbed with moisture content is under the extruding of extrusion roll, and moisture content is collected the back by captation and discharged from rising pipe.
Described conductive pressing plate flexibly connects by pillar and mud electric osmose dewatering unit, mud electric osmose dewatering unit is provided with at least one and is installed in reciprocating lever on the motor, reciprocating lever is connected the conductive pressing plate top, reciprocating lever can drive conductive pressing plate and pump, thereby mechanical presses is tiled in the liquid sludge of filtering on the belt, wherein free water is removed, thus make the utility model can the electric osmose dehydration again can mechanical dehydration.
As only handling the liquid sludge of having handled earlier by mechanical dehydration, described conductive pressing plate is fixedlyed connected with mud electric osmose dewatering unit by pillar, only carries out the electric osmose dehydration.
Described running gear main body is any one in car, ship or other transportation apparatus.
Since the utility model can electric osmose dehydration again can mechanical dehydration, this makes the mud that finally obtains very dry, by changing the limited factor of operation, dryness factor can reach 30%-50%, the utility model can move freely simultaneously, when pending mud transportation was inconvenient, the utility model can move to liquid sludge and carry out work with producing, can save a large amount of trucking costs.
