Description

A kind of magnetic loading precipitation filtration, purification system

Technical field

The utility model is related to a kind of integration precipitation filter, also relates to the device being used for magnetic loading filtering Cleaning system, more particularly to there is just heavy and secondary filter function the purification system of integration loading with magnetic force slag dumping mechanism System, it is adaptable to the big flow such as black and odorous water, mine water, Metallurgical Waste Water high-concentration sewage processing, belongs to separation of solid and liquid purification sewage Technical field.

Background technology

The issue of ' ten, water ', advances black-odor riverway waste water control significantly and municipal wastewater dephosphorization carries mark.This kind of big stream The big problem that amount sewage treatment project faces is that land used is nervous, it is necessary to efficient purification techniques.Disc type Magneto separate, magnetic precipitation, height The technology such as close clarification plus sand precipitation, filtering has certain engineer applied in river course water process and municipal administration carry mark.Wherein, it is high Close clarification plus sand precipitation, are big based on suspension flco density ratio water, purify sewage by gravity settling separation, advantage is than normal Inclined tube sloping plate deposition efficiency high is advised, is taken up an area relatively fewer.But the capacity of resisting impact load of this kind of settling system is poor, suspend Contain lightweight suspension flco in the increase of thing concentration or sewage, the problem of flco flows away with water outlet can be produced, caused under effluent index Drop.In recent years, isolation of purified it is more efficient thus it is alternative it is highly dense clarification, plus sand precipitation disc type Magneto separate and magnetic precipitation skill Art, obtains more popularization and application in sewage treatment project.Two kinds of technologies are all by adding magnetic kind and flocculant into sewage Magnetic flocculation reaction is carried out, suspension in sewage is combined to form magnetic flco with magnetic kind, then magnetic is carried out by disc type magnetic separator Power adsorbing separation completes separation of solid and liquid by way of magnetic sedimentation basin is settled, and removes magnetic flco, purifies sewage；Isolate Magnetic floc sludge enters magnetic kind recovery system, after breaing up flco through the flco disperser such as high speed agitator or high speed shear pump, Magnetic kind therein is reclaimed by magnetic kind recycling machine, recycled, the non magnetic sludge isolated enters dewaterer processing.With it is highly dense clear Clearly, plus sand sedimentation is compared, Magneto separate and magnetic precipitation be respectively provided with separation of solid and liquid speed faster, the smaller advantage of floor space, For removing insoluble pollutant in sewage, reduction COD, dephosphorization, there is good effect, be widely used in Metallurgical Waste Water, ore deposit Well water, black-odor riverway water, heavy metal wastewater thereby, stone material waste water, the purification of papermaking dyeing waste water, and municipal wastewater propose mark dephosphorization etc. Field.However, Magneto separate and magnetic sedimentation still suffer from deficiency.

By magnetic-adsorption separation principle, disc electromagnetic separating treatment is fastest, and system footprint area is small, but key equipment The magnet consumption of disc type magnetic separator is big, and cost of manufacture is high, and black-odor riverway Water warfare or municipal wastewater for big flow carry mark Dephosphorization etc., enormous investment cost makes its application by severely restricts；On the other hand, disc type magnetic separating apparatus capacity of resisting impact load Difference, concentration of suspension increases in sewage quantity increase or sewage, and outlet effect can substantially be deteriorated.

Magnetic precipitation belongs to loading precipitation, forms density by the way that dense medium magnetic is added into sewage and is combined with suspension big The magnetic flco of easy rapid subsidence.But magnetic precipitation will embody the advantage of more traditional subsidence style, it is necessary to be designed as higher table Face load, in this case, most of magnetic flco can be settled quickly, but small flco easily flows out with water outlet, influence Treatment effect.Solution one is reduction sedimentation basin surface loading in engineering, but loses comparative advantages, and system compares in itself Tradition sedimentation is complicated；Another method is to increase filtering ponds after sedimentation basin, generally using rotating disk filtering, so adds system Floor space and cost of investment, and rotating disk filter screen needs frequent backwash, water consumption is big, and moisture percentage in sewage sludge is high, increases operation Cost；Further, the sludge on filter cloth is aspirated in rotating disk filtering with negative pressure sucker, filter cloth failure, service life is easily caused Shorten, add maintenance cost.

Filtering technique is intercepted using self-cleaning laminated filter, drum filter, rotary disc filter as representative with filter screen physics Mode suspension is separated from sewage, therefore outlet effect is guaranteed.But in the case where concentration of suspension is high, mistake The filter capacity of filter is not enough, and filter screen is easily blocked, it is necessary to which frequently backwash, water consumption is big, and system sludge moisture content is high, increase Operating cost.So, the occasion that filter is used for the micro- pollution of small water is more, and is applied in big yield sewage treatment project It is less.In recent years, there is so class drum filter, certain application is obtained in municipal wastewater puies forward mark project, but in sewage Impurity is all intercepted through filter screen, is equally existed filter screen and is easily blocked, backwashes the problem of water is big, is not suitable for high concentration flood Quantifier mesh.Furthermore, the common working method of drum filter is to enter outgoing in sewage, and sludge is intercepted at filter cylinder inner surface, warp It is arranged at flush pipe above rotary drum to rinse, muddy water falls into the mud-collecting slot being arranged on the inside of rotary drum and discharged, thus structure compares Complicated and filter screen can be only in half submergence working condition, filter capacity does not give full play to, especially in big flow sewage disposal, this Plant defect apparent.

（3）Compared with filter is intercepted to the physics of dirt, magnetic precipitation, disc type Magneto separate, highly dense clarification plus sand precipitation, Open solid-liquid separation system is belonged to, capacity of resisting impact load is poor, suspension flco is easily lost in water outlet, outlet effect is difficult To ensure；

（4）This kind of opening is precipitated than highly dense clarification plus more efficient less Magneto separate, the magnetic of taking up an area of sand precipitation isolation of purified The solid-liquid separation system of formula, if increasing filtering ponds to ensure outlet effect, system footprint area and cost of investment all can Increase, and backwash water consumption is big, system sludge moisture content is high, increases operating cost；

（5）Disc type magnetically separating and purifying system footprint area is small, but equipment investment cost is high, and its marketing is applied by pole Big restriction；

（6）Whole magnetic flcos of some magnetic separating apparatus are intercepted by filtering, and filter screen load is high, and magnetic roller is partly immersed in The magnetic slag near the water surface is adsorbed in sewage, magnetic-adsorption ability can weaken when level fluctuation is big；Or whole magnetic waddings in sewage Body need to be adsorbed through magnetic roller, and magnetic roller is in preceding process in first absorption effluent after substantial amounts of magnetic flco, then adsorbs the magnetic of filter screen interception The ability of property flco weakens because of the magnetic screening action of magnetic slag, increases filter screen load, reduces filter capacity.Meanwhile, this A little magnetic separation filtration cleaning systems belong to greatly half submergence filtration system of jet pipe built in filter cylinder, and screen area is underused, Limited filtering capacity；Without magnetic kind recycling use function, magnetic secondary pollution is caused, and the big operating cost of magnetic consumption is high； Magnetic roller structure, whole cleaning system are all more complicated.
