Description
Technical field
The present invention relates to a kind of separation method of physics, method is specially the filter screen that filters timer, be arranged on the fixed position in the current in different water stream channels or in water body, form cross-flow filtration system, the espespecially a kind of filter screen of device can being placed in the current or water body of water stream channel of natural water or Artificial facilities, form large-scale cross-flow filtration system, utilizing current natures kinetic energy or man power to promote water flow dynamic energy is used as the water inlet of cross-flow filtration system and overcomes filter screen resistance and the major impetus of filtering, in the time that current pass through the filter screen of settling in system, clear water diafiltration flows away by filter screen or is removed by plug-flow, and suspension in water body is tackled by filter screen, promoted to enter in the dirt trap of system filter setting along strainer filtering surface current by the current of screen surface, the method that clear water is separated with the suspension cross-flow filtration in water body.The filtering surface of cross-flow filtration system filter screen of system institute operative installations in the time filtering is constantly washed away by current, or automatically kept clean (self-cleaning) by the auxiliary current scour of the strengthening cleaning device of operative installations, the filtering holes of filter screen can not get clogged, thereby has ensured that cross-flow filtration system can not be subject to the restriction containing concentration of suspension in water body.Thereby can be in the water stream channel of all sewage containing variable concentrations, according to different filtering accuracies, filter the application target of the water yield and isolated by filtration, design different different cross-flow filtration piece-rate systems, to the structure of the different strainer filtering device that uses containing the suspension of variable concentrations carries out that the method for continuous energy-saving isolated by filtration and method are implemented in different water stream channels.
Background technology
The Eutrophication materials such as nitrogen, phosphorus organic matter that now water body in the most lake of China, reservoir, ocean and river has all been brought into or produced by external source and Inner source pollutes, in water body, produce the suspended contaminant of the high concentrations such as blue-green algae, make the aquatic products production in these waters and the tourism of scenic spot be subject to great impact, particularly after the intake of water factory is polluted, the directly critical safe drinking water to people.The lakes and reservoirs, sea water is source of eutrophication of exogenous is from the urban and rural toilet defecation pipe, to the sewage pipe sewage base city, urban sewage water even after modern sewage treatment plant after treatment in water still contains 20% nitrogen, more than 5% of phosphorus and 90% of the potassium.Also have after agricultural use chemical fertilizer do not absorbed by crops that the Eutrophication materials such as nitrogen, phosphorus organic matter running off flows by surface or subsurface wastewater infiltration system after, the different Eutrophication materials in all sources all comes together in river, in the different water stream channels such as irrigation canals and ditches, form the multiple different high-concentration suspension pollutants such as mud, constantly flowing in lake, ocean, is the main cause of lake, ocean receiving water body eutrophication.
And from water body, isolated by filtration is out by the suspended solid pollutant thing of the high concentrations such as the mud in the different water stream channels such as sewage conduct, river, can Enough from different sources, reduce quickly and effectively difficulty and the load of sewage disposal, the pollution of river, lake, ocean water environment is destroyed after also reducing the diffusion of eutrophic pollution thing.Nitrogen, the phosphorus organic matter that can directly, fast and effeciently alleviate in lake water pollute the external source in lake, in lake, ocean, isolated by filtration is taken out different algae pollutants, can directly be reduced the eutrophic pollution thing in lake on a large scale, can also produce on the spot the clean water without algae, recover rapidly the ecological balance of lake, ocean.
But existing technology of tackling blue-green algae in water body has the waterproof or micro-permeable enclosure of Bian to be installed under water, stop floating blue-green algae, make a large amount of blue-green algaes not enter the waters of block isolation, the blue-green algae of block interception can be enriched in to block and go up and import to appointment waters, block low without filtering function or filtering function, only depend on interception mode to exist algae separative efficiency low, separating effect is not obvious, can not reach and determine matter, fast and effeciently separate the blue-green algae in water body quantitatively, obtain the problem of a large amount of better quality clean water.
The existing filter cloth disc converting device of installing and using in water body and fixed disk chip filter cloth or chip filter screen accurate filter are in the time filtering, adopt traditional in-line filtration mode to filter, also referred to as dead-end filtration, filtrate is flowed perpendicular to the surface of filter medium, impurity solid in water is held back by net, is being gathered in screen surface, is filtered pressure compression and forms gradually closely knit filter cake, its resistivity of the filter cake forming on filter screen is very large, so that the average rate of filtering of filtered water when the filter cake is very little; The ineffective energy consumption filtering is significantly increased, after the speed of sewage water filtration obviously reduces, by different filter net cleaning devices, rinse, the filter cake forming on filter cloth is rinsed, and suction or recoil, remove filter cake, make filter screen recover permeability, proceed filtration work again, complete like this work period, it is all the cleaning way that uses intermittence that filter cake is removed in backwash, recoil washes down apparatus structure and operational motion is more complicated, and intermittent operation reduces filter efficiency.Because equipment is when containing the sewage water filtration of high concentration suspended matter, the filter efficiency of equipment is lowly even invalid, therefore existing filter cloth (filter screen) equipment in use the suspension content of General Requirements sewage be generally limited in 30mg/l(solid content 3/100000) in, when using, this equipment must carry out again filtration treatment through pretreated sewage of equipment such as sedimentation basin of sewage disposal, guarantee equipment normally uses, and therefore equipment is mainly used in the back-end processing of sewage disposal process.And in the time that sewage by suspended substrate concentration is high, it is fast that filter cake on equipment filter assemblies forms speed, while using traditional filtering equipment directly to filter denseer blue algae water, in a few minutes, the filtration water yield of equipment just reduces significantly, the cleaning that recoils continually of requirement equipment, the filtration water yield of equipment is reduced greatly, and filtering energy consumption increases greatly.And recoil and comparatively complexity of flushing aspirator, can not fast and effeciently filter the carrying out of high-concentration sewage, while being used on a large scale natural water being filtered, recoil and aspirator are arranged the reason of more difficult or instrument size shape, equipment is mainly used in the depth-type filtration of dirty treatment plant, suitable environment or applicable concentration range are less, purposes and environment for use are single, and therefore the rare above-mentioned equipment that do not use is directly used in high concentration blue-green algae or other high strong sewage such as ight soil and mud are filtered to the report of practical application processing in other occasion.
Traditional cross-flow filtration operates compared with dead-end filtration complexity, to solid content higher than 0.5% feed liquid adopts cross-flow filtration conventionally.Traditional cross-flow filtration equipment mainly contains ultrafiltration, rotation chimney filter, and earthenware equipment, requires to use water pump high pressure, at high speed whole filtered fluids is carried out to cross-flow filtration, and the rate of filtration will be sought quickness, and generally will exceed 5-10 meter per second, filter pressure 0.4~0。6Mpa。When filtration treatment, require repeatedly circulation, therefore the large energy consumption of filtering traffic is high, also exist and make the main equipment with huge filter area can be subject to the restriction of filter medium, equipment shell and fabricating yard restricted, while being used in sewage water filtration on a large scale, investment and use cost are very high, therefore have no the report that above-mentioned filter plant is managed for the smelting of blue-green algae sewage on a large scale.
Existing Branchial filter, vibratory sieve, one cross-flow filtration equipment fast and effectively, on higher than horizontal plane, use flat strainer filtering assembly, do not need circulation just can realize significantly thickening filtration and remove blue-green algae, but filtered water must all be extracted water body out and be arrived the grand water surface upper filter screen equipment that is positioned to, lift is high, cannot utilize nature or the artificial kinetic energy of natural flows or the kinetic energy of man power plug-flow current in river, lake to filter, thereby filtration energy consumption is higher, on the water surface, only use in addition flat filter assemblies, the filter pressure that the filter screen of equipment can be born is less, cannot improve filter pressure, with the water yield that improves unit are, when filter mesh more hour, filter out the water yield little, thereby limit the raising of equipment filtering accuracy and filter efficiency.
Therefore, invent a kind of new filter separation method and implement the strainer filtering device different in water body that is arranged on using as method, object is at sewage pipe by different strainer filtering Zhuan Zhi An Catching-rabbits, river, in the water body of the different water stream channels in lake, the constantly automated cleaning of filtering surface energy Enough of the filter screen of the device using when filtration.The just different water flow dynamic energy low energy consumption ground continuous filtration sewage of energy Enough local use in water body, obtain a large amount of no suspended substance clean water, simultaneously can be by the blue-green algae in water body, the suspensions such as mud enrichment method exponentially on filter screen, and the pollutant of enrichment method is transported in the dirt trap of device, from water body, separate.So that efficient energy-saving ground takes out blue-green algae or mud water body or carries out other processing, filter method also may be used on the lavatory, source of the eutrophic pollution of sanitary sewage, ten points of the method for efficient energy-saving ground isolated by filtration and the applicable dress Catching-rabbits of the inventive method is directly carried out in the eutrophic pollution thing source of feces of toilet or other high concentration necessary.The method of invention also can be carried out for other industry the use that separates of accurate liquid and solid.

The manufacture principle of the work of method of the present invention and operative installations
Due to flexible knitting filter screen technical maturity, there is the braiding filter screen of a large amount of different precision, different size, unlike material can supply to select, the water resistance of braiding filter screen filter screen in the time filtering is low, and clear water permeability is high, easy cleaning.Therefore the filter screen of our invention operative installations (1) is to adopt flexible knitting filter screen and rigid strutting piece is compound makes, can make easily difformity, different filtering accuracies, the hard strainer filtering assembly of different area, large-scale filter screen can be connected and composed by different net-filter assemblies, the filter screen the settled hydrospace that can provide according to different water stream channels in use and discharge and obtain the difference of target containing concentration of suspension and filtration, design is by the difformity of device, the filter screen (1) of different filter areas uses support (4) directly in lake, different water stream channel or be connected with sewage routeway in river and in sewage conduct, form different cross-flow filtration Xi System, reach different filtration requirements.
Different with strainer filtering equipment from traditional cross-flow is, the filter screen of our invention operative installations (1) is arranged on to existing different water stream channel, or in lake, in the newly-built water stream channel in space in the water body of pond body or on the water surface or be connected with these water stream channels, in water channel, be separated to form clear water zone and contraminated zone by filter filter, the direction of the current in filtering surface and the water stream channel of filter screen is angle a, angle a is almost the arbitrarily angled arrangement except vertical angle, just can form different sizes, multi-form, the filter screen cross-flow filtration of different application targets is System, filter screen (1) filter area that Xi System installs is larger than the filter area of traditional cross-flow filtration equipment, filtration needn't be intake by iterative cycles, the natural pressure permeation filtration that sewage relies on the weight of water body and flows and produce under water, can be under less flow velocity and pressure diafiltration mode once filter and just can obtain the desired water yield of design, be difficult for forming closely knit filter cake because filter pressure is less on filter screen, the shearing force that feed liquid that different is produces while flowing through strainer filtering face is taken away the particle being detained on face or the dirt trap of inflow device, make constantly self-cleaning of filter screen, the filter screen of Xi System device is exposed in water body or space, convenient for installation and maintenance, also be conducive to use fixed installation or the mobile filter screen strengthening cleaning device (3) using to use vibration simultaneously, hydro-peening, scouring mode is directly strengthened cleaning to filter screen, ensure that strainer filtering hole is not blocked, so just can carry out different scales to the sewage that flows into system, the different continuous isolated by filtration that require.
When the sewage of friction speed flows into filter screen staggered when flowing through filter and being System, filter screen is passed through in a large amount of clear water infiltrations, because filter screen contacts with the current tangent line containing suspension sewage, the suspension of being tackled or intercepting and be concentrated by filter screen is constantly washed away along the different any direction of strainer filtering face guiding and is flushed away or rushes to the dirt trap (2) of screen cloth one end by current, make strainer filtering face automatically keep clean, in the time that cross-flow current cleaning filter screen is thorough, also can use assisted and strengthened self-cleaning device (4), powerful vibration in filtering, scrub or with gas or water flushing filtering net, can make on filter screen pollutant residual and not easy-clear be eliminated and leave filter screen, with the cross-flow current filter mud on mandatory removing screen pack surface simultaneously, guarantee equipment filter screen in the time of the work of filtration under any circumstance can not stop up by contaminated thing, therefore filter out the water yield insensitive to the variation of feed concentration, can be when not filtering the high and rapid minimizing filtration water yield of concentration of suspension.Because the method is applicable in nature or artificial different water stream channel, the isolated by filtration of the water yield and any concentration sewage arbitrarily.
The foundation of large-scale blue-green algae isolated by filtration system is to utilize lake or river, the huge water space of pond body is installed and is put large-area filter screen, filter screen arrangement areas and setting, not limited by legacy equipment housing and infield, filter screen can be made into the filter assemblies of difformity plate system or hollow, be combined into the filter screen of the different areas that varies in size by series winding or form in parallel, to be applicable to filtering lake surface wave plug-flow, lake water outlet potential energy plug-flow, or the different water stream channels of the plug-flow pump plug-flow of static lake water foundation, the sewage containing suspension of the different flow producing, in water body, set up different large-scale blue-green algae cross-flow filtration piece-rate systems, construction cost is low, can utilize easily different natural potential energy, or plug-flow pump enters effluent stream different cross-flow filtration piece-rate systems energy-conservationly, by system on the spot separating and filtering blue-green algae is separated with clear water, can obtain preliminary concentrated blue-green algae and clear water, according to different needs, the device that system is used is different, the filter screen of device filter screen is connected with dirt trap, can reach concentrated object of collecting the suspension such as blue-green algae or mud in water body, when the filter screen of device filter screen is connected with water collector, can reach the suspension in isolation water body, collect the object of clear water.When being connected with water collector with dirt trap simultaneously, can collect the filter screen of device filter screen clear water and concentrated suspension simultaneously.
In the large-scale cross-flow filtration system forming, the filter area of filter screen arranging due to system is large, filter efficiency is high, clear water when filtration in current can once permeate and pass through filter screen to property in low pressure condition, and low press filtration makes filter screen interception filter mud can not form solid filter cake on filter screen, easily taken away by the current of low speed, therefore system is not subject to the restriction of traditional cross-flow filtration equipment high pressure and high flow rate requirement, can be under the condition of low pressure low speed without the sewage of the cross-flow filtration variable concentrations that repeatedly circulates.
Suspension when filtration in current is filtered by the interception of the filter screen of filter screen cross-flow filtration system, suspension concentrated on strainer filtering face is installed respectively the different assigned address of pilot flow direction from a large amount of clear water that see through filter screen simultaneously, can collect individually or simultaneously clear water or concentrated suspension by the different water collector of equipment or dirt trap, reach the object of further processing or utilizing on the spot, particularly the dirt trap of equipment is except general container, also can use the existing or newly-built precipitation that has, buoyance lift, anaerobism, aerobic and plant ecological treatment pond, also can be a region of enclosure in lake, and drag for the dirt trap as equipment such as algae ship, in being stored in dirt trap or water collector, blue-green algae or clear water enter that a Walk is further concentrated or the physics in other difference in functionality pond, biochemical treatment, due to the use of the medium-and-large-sized water collector of system and dirt trap, physical method and biochemistry that system sewage disposal is used, ecological method is in conjunction with working in coordination with local use clear water and eutrophication pollution thing in the sewage disposal in lake.
Equally the filter screen of device is arranged in different sewage routeway or with sewage routeway and is connected, also can form different filtration systems, links different from source are taken out the trickle solid pollutant such as main source ight soil, mud of sewage eutrophication isolated by filtration from water body, directly reduce rapidly the load of the water environments such as sewage disposal and river, lake.
