Be a kind of 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, because of a large amount of poisonous emulsion that does not spread apart as yet that the chemical plant blast flows into, all belong to the associated field of same improvement method of a total design of the present invention.

Back of the body border technology

China's environment pollution, the pollution of especially a lot of rivers and lakes is extremely serious, much is the long stream in Heisui River, and millions of people are anxious, and blue mountains and green waters in the past is seriously damaged.This is that China payes attention to developing the economy, and the heavy cost that not have simultaneously enough attention ecological environmental protections to pay be not a fritter or several, but more than half Chinese most of area is all seriously contaminated, because of a variety of causes, has 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, land are by building all size Wastewater Treatment Plant, but because of being subjected to technology, investment limitation, are unable to catch up with polluting the speed that development need is administered, and still have large amount of sewage flowing to river, lake, sea.Need innovation study intensively out reliable efficiently, can large tracts of land administer, transform administer, can energy-conservationly significantly reduce investment outlay and the method for equipment, with control China because of economy develops rapidly caused more and more serious water pollution problems, especially to the pollution of water environment.China's Shandong Huang Island breaks into oil tank oil depot group serial blast in one's early years, and greasy dirt has dyed the Jiaozhou Bay half, suffers heavy losses.Serious water oil stain had in various degree all successively taken place and had dyed incident in waters such as Huangpu River upstream, Bohai Sea Gulf, the mouth of the Zhujiang River, entrance of Changjiang River, Song Hua River recently, Xiang River, Bei Jiang, section, Gongyi, the Yellow River in recent years, and also mostly is to cause tremendous loss.Prior art all is just to have collected some simple and easy ships manually to receive greasy dirt after serious water environment pollution incident has taken place temporarily.This backward situation utmost point need change.The little water contamination accident in China town and country is more in addition; enter polluted river water arbitrarily; accumulate over a long period; also serious pollution of water environment; need to perfect the legal system; improve whole people's environmental consciousness; can set up environmental protection day or enviromental protection week, organization and communications " protection environment; Everybody is responsible " to arouse the popular environmental protection of paying attention to participating in; it is required that this does not still administer environmental protection; also be to build vast harmonious society and new rural area is required, from now on along with the economic great development of China, to require the task of governance and protection China ecological environment will be more and more serious.

Summary of the invention

The present invention proposes a kind of land town domestic sewage of can receiving, control, industrial wastewater, and receiving, harness the river upward again, the large tracts of land greasy dirt dyes, the method for the poisonous emulsion pollution that does not spread apart as yet of chemical industry.

Method of the present invention is to propose to set up the big severe contamination river of each bar, the lake is the pollution treatment committee of unit, to this river, the lake basin pollution control is responsible for, accountability is with clearly defined objective, so that dirty rheology is cleaned, the recovery blue mountains and green waters is a sacred duty, this is very important, because China's severe environmental pollution is not a trifle thing, the problem that can solve only by administrative inspection. each pollution sources unit of order is supervised in leader's inspection, each factory oneself goes to have administered pollution, long-term fact proved, because of various complicated reasons, do not have Ying Youneng at all and administer the more and more seriously effect of environment pollution. when each bigger seriously polluted river or lake, set up the pollution treatment committee, plan as a whole this river, these lake basin pollution treatment all our undertakings, directly under State Environmental Protection Administration, authorize absolute authority, directly carry out national environmental protection act, each side's approval project verification in the affiliated basin is not conformed to the last right of veto by one vote of having of environmental protection, factory opened the door whether enough to produce that environmental protection has direct inspection power of approval, the most important thing is that each basin pollution treatment committee itself is a pollution treatment Construction unit, initiatively pollution treatment, initiatively to this river, lake basin complete investigation planning, set up the key technology of training pollution treatment troop, want thoroughly to cure pollution, 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, non-this does not touch, transform to administer bad various serious existing " score;; pollute; can not just pollute and can build well new pollution engineering of improvement on the basis of not curing; will make in order exactly and set up reasonable effectual pollution treatment institutional structure, put forth effort tenacious improvement and transformation and administered the serious pollution problem of China's ecological environment in " score ".

One of method of the present invention, be to propose along being built long main pipe by limit, riverbank, severe contamination river, loke shore limit, each pollutes the source region, factory district oneself transformation improvement is built up smaller branch pipe sewage is sent into main pipe, and all have stream, the little Heisui River bank that sewage flows out to build up branched pipe in general city, collection earlier flows to each bar smaller branch pipe sewage of little stream and sends into main pipe again, promptly use long main pipe broad the outer suburbs, cities and towns, each contaminated area of founding a capital, not building Wastewater Treatment Plant is together in series.All smaller branch pipe, branched pipe, main pipe all require high fine and close non-leakage reinforced concrete pipe, cast iron pipe or special anticorrosion steel pipe, comprise joint, so that sewage is non-leakage outside pipe in soil and the river in the pipe, this is will pollute the technological core of controlling to China one of to require, being determined not to be afraid of dirty not being afraid of toil overcomes difficulties, meticulous assaulting fortified position as long as reliable method is arranged, just can be controlled the serious pollution problem of China comprehensively.For each sewer of cities and towns, clear one by one, rainwater and sanitary sewage separately, sewage is collected with steel bar concrete garden well earlier, from the garden well stretch out smaller branch pipe again, branched pipe is sent into main pipe.Main pipe along the river, seashore limit, lake builds, can save useful land area and avoid the just excavated volume of landform, be convenient to tackle each bar sewage in the row of collection Xiang He, lake, sea, also do not miss for one, more be to become the door hurdle of thinking any Pai He, lake, extra large sewage from now on.Build long main pipe, could touch to transform and administer good existing severe contamination problem, could collect large tracts of land sewage, just can build ultra-large type high-efficiency sewage treatment plant, could administer the target fast, that reached province of producing effects.What of each pollution sources sewage that main pipe can will insert according to river, place, loke shore perform design together, and leave the flange branch pipe connection that development in the future inserts.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.Smaller branch pipe, branched pipe sewage are sent into main pipe after generally only removing sand, removing the gred, some can be established the well pump room and squeeze in the main pipe with flexible pipe from main pipe regulating water level regulating the qi flowing in the channels well head, but height contains many metals sewage such as cadmium wants (as build tailing pit and handle) after the specially treated, just sends into main pipe.Main pipe is transported to Wastewater Treatment Plant with the flow velocity gravity current that the end longitudinal gradient of needs forms about 1～1.5m/s, and some pipeline section can form pressure current and carries sometimes, is regulated by the regulating water level well, regulates Jing Yuanding and will exceed the river extreme high water.The main pipe terminal should be selected in certain area shallow water river bend, river protective embankment place, so that build Wastewater Treatment Plant of the present invention.The present invention proposes along the river, loke shore is built long main pipe, also has another big purposes, promptly, water surface generation oil carrier leaks out a large amount of greasy dirts when being hit, or because of the blast of chemical plant on the bank flow into but during the severe contamination disaster events such as a large amount of poisonous emulsions that do not scatter as yet or impaled, available receipts oil, dirty equipment collect to squeeze into carries (see below and state) in the main pipe, therefore bank is built long main pipe, also is to tackle the necessary equipment of above-mentioned disaster on the water surface.

Two of method of the present invention, be to propose a kind of Wastewater Treatment Plant, be to go into the discharge bay section after the main pipe outlet concrete the composition, connect drop-down section, connect the long settling pool section of highly effective reaction, connect the shallow solar pond broad crested weir section that cross-current is crossed, connect and be scattering into natural biological purification stabilization pond after the filtering bodies section is gone in the overflow of thin-walled crest of weir, so that just discharging after real up to standard the exceeding standard.Be that long distance adds nontoxic chlorine dioxide effective catalyst (liquid) and aluminium salt inorganic coagulant through regulating water level regulating the qi flowing in the channels well head before the main pipe outlet, black smelly serious as sewage, also available bend pipe shower nozzle adds oxygen, utilize in the pipeline section inner sealing, normal temperature, turbulent condition of the quite long distance of main pipe fully all contaminations in the mixed catalytic oxidation reaction degradation of sewage, the virus that disappears, sterilization.This Wastewater Treatment Plant that main pipe outlet back is built, specific design is: main pipe outlet top will be lower than about the 1.5m of discharge bay underwater, make gush shape energy dissipating at a slow speed to flow out main pipe, the discharge bay lower exit wide will with the long settling pool beam overall of wing-rooms on either side of a one-story house with wide, be to fall into the long settling pool of wing-rooms on either side of a one-story house sewage behind the discharge bay with drop (falling about poor 1.5m), establish dull and stereotyped control inlet gate at preceding drop top bank, so that a railway carriage or compartment short time cuts off the water when washing, the short time enlargement discharge operation that does as usual of another railway carriage or compartment, two sintering TiO of device on the drop wall ₂The rotating cylinder of blade, last rotating cylinder diameter is little, following rotating cylinder diameter is big, drop stream impulsion rotating cylinder, it is oxygen-doped that dispersed gas is filled in the sputter of current intersection, after evenly being scattering into the long settling pool water surface, sewage advances at a slow speed in settling pool, the general depth of water 3m of settling pool, the rectangular cross section size is controlled at about 0.3m/s according to sewage velocity of approach in settling pool and decides, and continues to make pollutant in the wastewater efficient reaction degradation of sewage, and the mud that produces sinks in the pond gradually, making the dephosphorization of wastewater efficient denitrification, remove COD and lead height, degraded all contaminations rate height. the upper strata is laterally flow through shallow solar pond broad crested weir section at a slow speed than clear water stream, the depth of water is (about 30cm) approximately, the certainly thin cobble that embedding is completely exposed in the base concrete of pond is provided with the upright net of arranging of at interval uniform in length and breadth stainless steel wire in the pond, all spray the sharp type TiO of admiring of molecular sieve nanoscale ₂Semiconductor catalyst, pollutant in the further degradation of sewage of sun natural light irradiation (shine with spotlight evening) photochemical catalytic oxidation sterilization, current after the degraded become drop to go into to drop through the overflow of thin-walled crest of weir, and the close-up attaching on the skew wall framework is the filtering bodies of main material with quartz sand, activated carbon, further filter again in the sterilization degradation of sewage behind the pollutant, be scattering into the following natural biological stabilization pond water surface, make and further purify the discharging again that exceeds standard up to standard again.Filtering bodies also all sprays TiO to paste close steel screen layer in the corrosion resistant plate shell ₂Filtering bodies has the spill gool, afterbody has gate control, control sluice is to close mud etc. to be fallen within the groove store at ordinary times, and at the bottom of the spill gool longitudinal gradient and sharp-crested weir to flow the top longitudinal gradient downstream identical, when reducing water level towards mud with the long settling pool of box lunch, utilization is located at People's Bank of China's service bridge of thin-walled weir crest, fill the washing and filtering body with water under high pressure, be that each the square filtering bodies in the framework is fallen excessive flushing, at this moment gool afterbody gate is opened, so that flushings such as the interior mud foreign material of gool are walked, has washed late gate and has closed.Mud also pours in the settling pool and washes away well in the shallow solar pond that adverse slope is arranged of holding concurrently simultaneously.

Flushing for mud in the long settling pool is because of being provided with the vertical degree in 3% end at the bottom of the pond, the pond tail is provided with sluice gate, when needs wash, regulating gate closes to lock and goes out stream on the preceding drop of the customs director of the elder generation settling pool bank, opens pond tail slide brush gate again, and the pool inner water position is lowered into torrent rapidly, the thick mud that becomes silted up in the pond can be gone out soon, dense mud flow steep canal behind hushgate flows away, and is transported in regular turn to gather in the mud mummifying pool of forming in three railway carriage or compartments and deposits pending transhipment utilization, as doing fertilizer use etc. by analysis.

The general present municipal sewage plant that has, the capacity of disposing of sewage is little, general day disposes of sewage and has only about several ten thousand to tens0000 m3/d, relative also relative complex of big, the technical pattern of construction investment, the improvement contaminated area that is covered is also little, this is that restriction China respectively pollutes the source region, builds the reason place of Wastewater Treatment Plant's difficulty.This Wastewater Treatment Plant carries sewage quantity big because of adopting long trunk pipe range to collect apart from large tracts of land, adopt hydraulic engineering design experiences and sewage disposal technology to require to combine, designing disposes of sewage can reach about 800,000 m3,1,000,000 m3 day all can realize smoothly, as being example with 1,000,000 m3/d, the per second flow is a 11.6m3/s also, and design is easy to realize that the pipe flow area is also little to main pipe for this, in addition full main pipe is ascending, begins long little apart from flow in the pipe.The every railway carriage or compartment of wing-rooms on either side of a one-story house settling pool design discharge also is 5.8m3/s, and is wide 6 meters as long 50 meters of tentative settling pool, 3 meters of the depth of waters, and mean flow rate is only about 0.32m3/s.As decide shallow solar pond broad crested weir, the long 40m of sharp-crested weir of cross-current warp, and an overflow discharge per unit width 0.145m3/s, depth of water flowing over weir is also little on the sharp-crested weir, all can realize smoothly.The innovation type Wastewater Treatment Plant we can say that a pond equals many ponds, it is big that the contaminated regional area of improvement is administered and transformed to topped energy, this counter investment much less, total steel bar concrete amount is also little, the operation workload is littler, and the equipment of disposing of sewage is few, energy-conservationly need not build sludge dewatering workshop and machinery, can realize automation mechanized operation, the water treatment effect is efficiently thorough.

The severe contamination incident that the end of last year, the blast of Song Hua River Yin Jilin a pair of benzene chemical plant caused; again rung alarm bell to China; China's water resource lacks; will pay attention to Three Gorges from now on; Xiao Langdi; the south water to north and important river; the protection in lake; pollution must not; must there be the vigilant eye of being responsible for to treat; as along limit, riverbank, cities and towns; after building up the innovation ultra-large type Wastewater Treatment Plant about long main pipe of the present invention and day processing 1,000,000 m3/d; when the pollution that serious greasy dirt dyes or the poisonous emulsion of chemical industry is not scattered as yet takes place in above-mentioned waters; will in time receive greasy dirt equipment (spending the greasy dirt time can be not oversize) with the advanced greasy dirt that encloses; receive except that above-mentioned pollutant from the water surface; squeeze on the bank in the main pipe; carry together with sewage; during long settling pool can before and after gate all open; reducing water level is delivered directly in the former mud mummifying pool in a railway carriage or compartment in three railway carriage or compartments and stores; the chemistry oil that disappears again; dirty; in order to protect water resource; when serious pollution disaster incident takes place in above-mentioned important waters; the way that tackles has just been arranged. on the riverbank that does not have cities and towns; also to build long main pipe; but its end is to build dirty pond of oil storage separately and silting thing; when taking place, dyes greasy dirt; be used to carry the collection greasy dirt to go to the dirty pond of special-purpose oil storage; when not having the greasy dirt hair dyeing to give birth to; the sand that is used for dredging under the transporting water goes to the sand yard; silt silts up seriously under water; it is the key that changes river channel ecology; will enough pay attention to from now on; do not wait Three Gorges; Xiao Langdi suffers just improvement of disaster revenge because of silt causes disaster; that is just late. and water is mistake from the storehouse; silt is mistake from pipe on the bank; be Chinese needed in the high concentration of sediment characteristics. the big reservoir of China; the power station is for taking precautions against natural calamities; country and relevant important department leader; to conscientiously pay attention to the Application and Development of national intellectual property patent; please develop: " a kind of oil enclosure and oil collecting device " (patent of invention ZL01106903.1 with fence and oil-collecting device; improved ZL2004100230584) and " the oily dredge boat of a kind of multiduty receipts " (the improved ZL01106902.3 of the patent No.: ZL96235015.X) from now on; each important river of China; coastal each important port management unit; Three Gorges; the Danjiangkou; important run unit such as Xiao Langdi will be paid attention to exploitation with long-range eye and store the foregoing invention patent equipment; in a single day or else to be used for when serious marine pollution incident taking place is to be unable to cope with just. pay attention to taking precautions against natural calamities, this is national affairs.
