Method dirty, pollution treatment that a kind of large tracts of land is received

Technical field

Be the method that a kind of large tracts of land is received dirt, pollution treatment, be receipts, control the large tracts of land greasy dirt that breaks leakage on land town domestic sewage, industrial wastewater and the water surface because of oil carrier, all belong to the associated field of a total design of present technique method.

Back of the body border technology

China's water pollutes, ecological pollution is extremely serious, much be the long stream in Heisui River, millions of people are anxious, blue mountains and green waters in the past, be seriously damaged, be not a fritter or several, but most of area of more than half China is all serious contaminated, because of a variety of causes, become and can't effectively control, it is rotten to cause soil, underground water to degenerate, and the impotable area of well water river is a lot, has a strong impact on people's life health and social stability.Prior art is by building all size Wastewater Treatment Plant, but because of being subjected to technology, investment limitation, is unable to catch up with polluting the speed that development need is administered, and still has large amount of sewage flowing to river, lake, sea.Need innovation study intensively out more reliable efficiently, can large tracts of land administer, comprise transform administer, can energy-conservationly significantly reduce investment outlay and technology, the method for equipment; with control China because of economy develops rapidly caused more and more serious water pollute, ecological pollution; the valuable water resource of protection China, this is one of basic Construction Problems of China.

Summary of the invention

Being to propose a kind of large tracts of land to receive method dirty, pollution treatment, is to receive, to control cities and towns, land, country life sewage, industrial wastewater, and receiving, harness the river upward again, oil carrier is broken the method for leaking out the large tracts of land greasy dirt.

This a kind of large tracts of land is received method dirty, pollution treatment, at first be that to propose to set up the big severe contamination river of each bar, lake be unit or be the pollution treatment special commission of unit with metropolis along the river, be that this river, the serious water pollution in lake basin, ecological pollution are administered full-time being responsible for, accountability is with clearly defined objective, with dirty rheology clear stream, the recovery blue mountains and green waters is a sacred duty.This is very important, because China's water pollutes, ecological pollution is not a trifle thing, is not a fritter, only supervises the problem that can solve by administrative inspection.The leader only checks and supervises each pollution sources unit of order, each factory oneself to go to have administered pollution that long-term fact proved, because of various complicated reasons, does not have and can thoroughly control good effect.When being unit with bigger seriously polluted river, lake or being that unit sets up the special pollution treatment committee with metropolis along the river, all our undertakings are administered in river, lake basin water pollution under planning as a whole, authorize absolute authority, directly carry out national environmental protection act, on-the-spot existing pipe, as the last right of veto by one vote that has, new factory opened the door whether enough to produce that environmental protection has direct inspection power of approval the defective environmental requirement of each side's approval project verification in the affiliated basin.The most important thing is that it is exactly water pollution control major project Construction unit that each special pollution treatment committee itself begins, can lead and set up pollution treatment technology construction team, major project under also can building by the believable unit in charge of construction of bid is to drive the whole people's pollution treatment of taking active action of each department, each pollution sources unit.But earlier will be by patented technology of the present invention to belonging to the river, the lake basin performs investigation planning comprehensively, finish the design by the patentee except that major project then, other like rain dirt shunting pipe network, but also commission business designing unit design, wanting thoroughly to cure water pollutes, will be determined to exert, it is difficult to overcome, as building highway and hydraulic engineering, drop into enough fund technology, initiatively start to build the pollution treatment major project, to drive comprehensive pollution treatment, be determined pollution treatment as long as see government, each pollution sources unit well separately pollution engineering of improvement of will taking active action, Here it is, and machining function is deep in the concrete engineering construction of pollution treatment goes.Non-this does not touch, transforms administers bad various serious water pollutions and existing " score " pollution, can not just pollute can build on the basis of not curing at " score " water and administer good new water pollution engineering.The method that this large tracts of land is administered water pollution, ecological pollution is exactly will carry out the pollution treatment system innovation earlier, just can get twice the result with half the effort, and request is paid attention to.

This a kind of large tracts of land is received dirty, two of the method for pollution treatment, be to propose the edge by the river of severe contamination, the lake, the sea, long main pipe (1) is built on the bank, each pollutes the source region, the good pollution engineering separately of improvement is administered or transformed in factory district oneself, with smaller branch pipe (2) sewage is sent into main pipe, and all have stream, the little Heisui River bank that sewage flows out to build up branched pipe (3) in general city, collect earlier and flow to each bar smaller branch pipe sewage of little stream and comprise that exhausting sewage all sends into main pipe, promptly use long main pipe broad the outer suburbs, cities and towns, build, do not found a capital each contaminated area of Wastewater Treatment Plant is together in series.All smaller branch pipe (2), branched pipe (3), main pipe (1) all require high fine and close non-leakage reinforced concrete pipe, cast iron pipe or special anticorrosion abrasionproof steel pipe, comprise joint, so that sewage is non-leakage outside pipe in soil and the river in the pipe, being determined not to be afraid of dirty not being afraid of toil overcomes difficulties, meticulous assaulting fortified position just can be controlled the serious water pollution problems of China comprehensively.Will pay attention to the thorough improvement of cities and towns, country life sewage especially, city, township's sanitary sewage are the roots that is rich in germ, viral eutrophication severe contamination river, pay little attention in the past, will pay attention to the city now, township's sanitary sewage is thoroughly administered.For the town domestic sewage sewer, clear one by one, rainwater and sanitary sewage separately, sewage is collected with steel bar concrete circle well earlier, from the circle well stretch out smaller branch pipe again, branched pipe is sent into main pipe.Main pipe along the river, seashore limit, lake builds, and can save useful land area, is convenient to tackle each bar sewage in the row of collection Xiang He, lake, sea, also do not miss for one, more is to become the door hurdle of thinking any Pai He, lake, sea from now on.Build long main pipe, could touch to administer and transform and administer the good existing severe contamination problem of leaving over that comprises, could collect large tracts of land sewage, just can build big Wastewater Treatment Plant, could administer and produce effects soon, reach faster and better target.What of each pollution sources sewage that main pipe can will insert according to river, place, loke shore perform design together, and stop the arm flange socket of the band valve that development in the future will insert.Main pipe sectional or full section are built, and be less as the opposite bank pollution sources, can establish branched pipe and collect crane span structure again and cross the river and send in this bank main pipe.As the semiworks pollution condition lighter, also can apply for directly after only removing sand, removing the gred, sending into main pipe, but pollute big more special pollution sources, could send into main pipe with smaller branch pipe after oneself handle sewage well.Each pollution sources also can adopt this patent design drawing downsizing, links main pipe from smaller branch pipe, improves connection as the low pump of can establishing of elevation, and the main pipe end generally will be established pump and improve so that connect Wastewater Treatment Plant.Main pipe generally is transported to Wastewater Treatment Plant with the flow velocity gravity current about the end longitudinal gradient formation 1～1.5m/s of needs, is regulated by regulating water level (regulating the qi flowing in the channels of holding concurrently) well in the way, and regulating water level well (5) dome will exceed the river extreme high water in regular turn.The main pipe terminal should be selected in certain area shallow water river bend, river protective embankment place, reaches the big Wastewater Treatment Plant of 100-120 ten thousand m (seeing accompanying drawing 1) so that build this day output.The present invention proposes along the river, loke shore is built long main pipe, also has another big purposes, promptly broken when leaking out a large amount of greasy dirt when river face generation oil carrier, equipment such as available China self-designed receipts greasy dirt ship, oil-collecting device collect to squeeze into carries (seeing aftermentioned for details) in the main pipe, therefore bank is built long main pipe, also is to tackle the water surface the necessary equipment of above-mentioned disaster takes place.

This a kind of large tracts of land is received dirty, three of the method for pollution treatment, be to study intensively out to dispose of sewage a kind of day to reach large-scale wastewater treatment plant about 100-120 ten thousand m, be to rise by going into discharge bay (6) section after main pipe (1) outlet concrete the composition, connect long settling pool (9) section that wing-rooms on either side of a one-story house are formed, connect by come in and go out shallow solar pond broad crested weir (11) section under it of long settling pool cross-current, connect at last through the overflow of broad crested weir tail and fall natural biological stabilization pond under it, wherein before the long settling pool of wing-rooms on either side of a one-story house inlet gate (7) is arranged respectively, tail respectively has sluice gate (10), connect the steep canal of mud behind the sluice gate, connect the nitrated mummifying pool of many railway carriage or compartments mud again, form this sewage Wastewater Treatment Plant together, wherein big natural biological stabilization pond has been built causeway and river, lacustrine facies every, be provided with logical river gate in the dike.Specific design is that main pipe outlet top will be higher than about 1.5 meters of the discharge bay waters surface, be outside the main pipe outlet, to build the big concentric circles girth sheets of flaring, be to fall stepped plate step by step, low step by step abundant aeration is oxygen-doped around making main pipe outlet current direction, discharge bay outlet wide will with the long settling pool water surface of the wing-rooms on either side of a one-story house under it beam overall with wide, effluent stream is scattering into the long settling pool water surface, be provided with inlet gate (7) control, the long settling pool depth of water is not less than 5-6m, the rectangular cross section size is controlled at below the 0.3m/s according to mean velocity in section and decides, the technology of in main pipe, disposing of sewage, be to utilize before the main pipe outlet, quite to grow on the main pipe of distance, through regulating water level well (5) mouthful adding chlorine dioxide (liquid), also can use the bend pipe shower nozzle instead and add ozone and master, auxilliary coagulant together, utilize the quite long closed frame tube of main pipe, turbulent flow, abundant down mixing of normal temperature state carried out pollutant in the oxidation reaction degradation of sewage. and sewage advances at a slow speed after flowing to long settling pool, in long settling pool, it is the innovative approach of studying intensively out a kind of Nover practical that realization aquatic organism contact oxidation method disposes of sewage, promptly be that the stainless steel tube of reinstating suitable diameter at the bottom of the pond is built into fixed bed framework under water, in framework, tie up the circle bundle of growth with straw or tangerine bar, be stacked and placed in length and breadth and become filler in the framework, between bundle suitable space to be arranged, straw, tangerine bar contact surface is long-pending big, life-span is long in water, machinery hangs, change easily, blast fan is by the eyelet gas distribution oxygen supply of pipe laying UNICOM framework horizontal tube in the base plate, make the microorganism concn height of generation, remove organic pollution efficient height. the mud of generation is few, sink gradually in the pond, make the dephosphorization of sewage denitrification, remove COD and lead height.After effluent stream bio-contact oxidation in long settling pool (9) is handled, effluent stream is that cross-current is through hole (13) outflow under water of long external wall, flow into shallow solar pond broad crested weir (11) section under it, in side wall hole import under water name, be provided with hole gate (12), behind gate, be provided with flat frame activated carbon filtration body (14) filtration that can propose maintenance from gate slot, thereafter being provided with the outer dirty

day, in order that thoroughly remove heavy metal, germ, pollutants such as virus, do not make to flow in the later current and go, the thorough comprehensive regulation that Here it is, because in long main pipe with already oxidised removal heavy metal ion such as ozone, add straw in the settling pool, the interception of tangerine bar is removed, add activated carbon filtration body absorption in the hole, milipore filter, reverse osmosis membrane cuts dirty lace curtaining and cuts dirt, this is that multiple tracks of the present invention is removed heavy metal ion etc. in a large number, since long settling pool processing water outlet be from a length of side external wall under water hole laterally flow out, waterborne contaminant can not flow to shallow solar pond broad crested weir section in stabilization pond in the long settling pool.Push up above side wall height because of hole again, the above superelevation waterborne of the promptly long settling pool water surface has enough height, increasing factory in future increases a certain amount of sewage quantity and also can satisfy, do not need enlarging, for dirt, the mud of long settling pool in sinking is entered under water in the hole mouth, this needs at the bottom of long settling pool enough height will arranged at the bottom of the hole import, for example be not less than 1.5 meters, therefore long settling pool fixed bed framework (8) be from can not filling straw, tangerine bar filler in 1.5 meters height at the bottom of the pond, brushes gate (10) and washes away in the sludge drying pond opening the pond tail slide with mud in the urinal.The white thin cobble that embedding is completely exposed in the white mixed concrete floor of shallow solar pond broad crested weir (11) section is provided with the upright row of the uniform Stainless Steel silk of spacing net in length and breadth in the pond, all spray the sharp type TiO by the emperor himself of firm molecular sieve nanoscale ₂Semiconductor catalyst is to utilize sun natural light irradiation (shine with ultraviolet light evening), and further profound level is carried out remaining pollutant in the photochemical catalytic oxidation sterilization degradation of sewage stream again.Last current are scattering into the natural biological stabilization pond that big water area is arranged under it through the overflow of broad crested weir tail, through stopping, the bio-absorbable differentiation, microbial metabolism is decomposed, make the three class active water standards that reach, be not have nitrogen, phosphorus, heavy metal, virus, germ, blood fluke, and a large amount of organic pollutions etc. entered in the stabilization pond.Can build up large-scale circulation and continue the stable source of water of utilization again, to be used for industrial water use, to be used for agricultural and can to irritate general vegetables, fruit, flowers etc., because of there not being pollutions such as heavy metal, germ, virus and large amount of organic pollutant, harmless, also contaminated soil not.To seldom open stabilization pond embankment (18) and go up logical river gate (19) and be discharged in river, the lake and go in the hope of reaching this stable source of water utilization is intact, even but enter on a small quantity in river, the lake, because of being the mixing of three class active waters and natural river water, can satisfy the drinking water source standard.Along the river all build up this improvement water and pollute reasonable engineering in each metropolis as the whole nation, just can reach protection China river, the valuable water resource in lake, also can eutrophication not produce disasters such as Lan Zao, progressively to recover the good water ecological environment of China.

Importantly, also can cancel the broad crested weir (11) of stating above, current are through side wall hole (13) under water, directly overflow to the large-scale natural biological stabilization pond under it, shallow solar pond is rectangular that puts in order out in the natural biological stabilization pond under it about a long piece depth of water 30cm, use the white cement shop fixtures, be provided with the upright row of the uniform Stainless Steel silk of spacing net in length and breadth in the pond equally, also all spray the TiO2 semiconductor catalyst, shining upon the same down further degradation water mid-deep strata of photocatalysis time each the remaining pollutant that rises, the cancellation broad crested weir can have been saved bulk steel bar concrete engineering quantity that broad crested weir (11) segment length is abundant, more can reduce investment outlay.

Flushing for mud in the long settling pool is to be provided with the vertical degree in 1/500 end because of the end in the pond, because of inlet gate is arranged before the pond, the pond tail has sluice gate, when mud in the pond need wash, inlet gate closes to gate and goes out stream before the customs director of the elder generation settling pool, open pond tail slide brush gate again, the pool inner water position is lowered into torrent rapidly, mud can be gone out soon in the pond, dense sludge stream is steep canal behind sluice gate, be transported in regular turn in the sludge drying pond of many railway carriage or compartments forming poly-deposit pending, it is hang-up that the mud transhipment utilizes, the present invention studies intensively first proposition mud and rubbish mechanical mixture through investigation, with the void content moisture content that improves mud again and straw, tangerine bar cutting machine mixes, make into inflammable body, because of the mud height contains organic matter is flammable, mix with a certain proportion of coal again, be used for generating, mud, rubbish is greatly extremely difficult because of measuring big harm, and is big as sludge garbage landfill area, the filtrate diffusion of raining, serious pollution of ecological environment, now turn to useful resources and be used for generating and consume, connect heavy metal ion, germ, virus is all wiped up, and is to have great economy, Significance for Environment, its ashes also can be used for brickmaking, and this exploitation can develop into the new industry and the new source of economic growth, the area stable pool of three class water, the volume increase of also can breeding fish in a large number, can enlarge social employment, achieve many things at one stroke, request is paid close attention to and is supported.

General existing municipal sewage plant, the capacity of disposing of sewage is little, general day disposes of sewage and has only about 20-40 ten thousand m, power consumption, and the operation mechanical quantity is big, workload is big, relative also relative complex of big, the technical pattern of construction investment, the improvement contaminated area that is covered is also little, lack to pursue the comprehensive high standard improvement of faster and better overall situation condition, and improvement is polluted not thorough, not having high standard to administer as heavy metal, germ, virus etc., generally is the emergent small sewage treatment plant of just setting about disperseing to build.And this a kind of large tracts of land is received dirt, the sewage treatment project that the method patent of invention of pollution treatment is built, for going deep into the thorough comprehensive regulation, as adopt long trunk pipe range to collect and carry sewage quantity big apart from large tracts of land, adopt hydraulic engineering design experiences and water prevention and cure of pollution engineering philosophy to require to combine, the day of designing disposes of sewage and reaches 100-120 ten thousand m and deeply study intensively design, comprehensive development and utilization, and be practicable, as being example with 1,000,000 m/d, the per second flow is a 11.6m/s also, design is easy to realize to main pipe for this, the pipe flow area is also little, in addition full main pipe is ascending, begins long little apart from flow in the pipe, engineering quantity is also little, to the every railway carriage or compartment of wing-rooms on either side of a one-story house settling pool design discharge also is 5.8m/s, as long 80 meters of tentative long settling pool, wide 8 meters, 6 meters of the depth of waters, pond water surface longitudinal gradient calculates by 1/100, and mean flow rate is only about 0.12m/s in the pond.As decide the shallow solar pond broad crested weir or the sharp-crested weir of cross-current warp, and the wide 40m that presses of weir water inlet, an overflow discharge per unit width 0.145m/s, weir tail end depth of water flowing over weir is also little, and the overflow scouring force is also little, all can realize smoothly.This large-scale wastewater treatment plant can say that a factory equals many factories, it is big that the contaminated district of improvement area can be administered and transform to covering, counter investment is little, energy-conservation, operational outfit is few, because of day the amount of disposing of sewage big, relatively sludge quantity is also big and concentrate, just in time concentrate exploitation to be used for generating to replace the expensive coal of a large amount of valencys, the big problem that solution mud, rubbish are difficult to handle.

Also have, oil carrier taking place on river, seawater face break, reveal a large amount of greasy dirts and dye on river, seawater face, just can in time receive greasy dirt equipment with the advanced greasy dirt that encloses, pack up greasy dirt from the water surface, squeeze on the bank in the main pipe and sewage is carried together, during long settling pool can before and after gate all open, reduce not effluent of water level, be delivered directly in the railway carriage or compartment mud mummifying pool in many railway carriage or compartments and store, the short time dosing chemistry greasy dirt that disappears again, short-term is disposed.About receiving greasy dirt, enclosing greasy dirt equipment can develop: " a kind of oil enclosure and oil collecting device with the oil fence and oil-collecting device " (patent of invention ZL01106903.1, improved ZL2004100230584) and " the oily dredge boat of a kind of multiduty receipts " (the improved ZL01106902.3 of the patent No.: ZL96235015.X) each important port management unit, Three Gorges, the Danjiangkou, important run unit such as Xiao Langdi will be paid attention to the APEL plan that united nations environment programme division proposes with long-range eye, meaning i.e. the APEL plan of " local level emergency episode consciousness and preparation " attention the United Nations, set about planning in the hope of the river takes place, during seawater face burst oil spill accident, not to be unable to cope with.

The engineering layout pattern technical method of disposing of sewage of this large-scale wastewater treatment plant; also can be used for such as the water purification at south water to north water channel, place, total feeding conduit end, city, except that silt, sterilization, sterilization, denitrification dephosphorization; the life water source treatment plant of removing all contaminations such as heavy metal is to reach high standard; the high water quality protection people's hygiene and health, significant equally.
