Abstract
A method for in-situ dewatering of the silt in water system of urban area includes such steps as preparing the tubular bag whose size and shape are determined by the local terrain, digging the silt from the bottom of lake or river and conveying it in said tubular bags, and laying aside for filtering the water under the action of the pressure from bag wall and the dead weight while solidifying the solid for 3-5 weeks.
Description
Technical field
What the present invention relates to is a kind of to urban waters and the sewage work's mud method of environment-friendly high-efficiency dewatering and coagulating on the spot, belongs to sludge dewatering Technology field.
Background technology
A large amount of pollution substances enters city river, lake, and accumulation forms mud in lakebed, river bed year by year.The employing that the processing of mud is had be to concentrate desilting as an engineering, yet it need solve the problem of outlet of mud.The employing storage silt pond precipitation that has is fixed, but this method not only needs long-distance pipe or groove tank car to carry mud, but also need take a large amount of soils; In addition, also have and adopt the fixed method of settling tank sludge dewatering, this method is quite very long to silt deposit, dewatering and coagulating time, generally needs 6～9 months, and the harmful element in the silt slurry permeates the ground, and causes migrating property secondary pollution.Because the poverty-stricken condition of existing sludge treatment technology, that have even violating the regulationsly mud is entered great rivers cause the regeneration of contaminated incident to occur repeatedly.
Summary of the invention
The present invention is directed to the existing defective of above-mentioned all methods and propose a kind of dewatering and coagulating of environment-friendly high-efficiency on the spot technology, a safety is provided, has solved the effective way of the bright skill of urban waters and sewage work's mud outlet economically.This art solution: the dewatering of urban waters mud, by the dedicated pump system city river, lake silt or sludge of sewage treatment plants are delivered to paste (high density) in the pipe bag of the high filter degree of high strength of lakeside, river bank or sewage pool side, the diameter and the length of this pipe bag can be made according to site contour; Utilize bag wall pressure power and deadweight effect, the most of water body in the mud is comparatively fast filtered by bagging discharge (can be up to standard substantially); Solid fine particle comprises that the objectionable impurities that is adsorbed on the fine particle surface then is trapped within the bag fixed, 3～5 weeks of consolidation time, the soil body after fixed has certain shearing resistance, can be used as the dike core of Hu Di, river levee, also can be used as Tu Yuan and offers other and use native department; To the mud that contains hazardous substance, then can be transported to the refuse landfill landfill.
Advantage of the present invention: effectively solve the problem of outlet of municipal sludge, use this law to need not long-distance pipe or groove tank car conveying mud; Because the water of the fixed discharge of sludge dewatering can be up to standard substantially through the filtration of the special bagging of pipe bag, the harmful element in the silt slurry no longer permeates the ground, and avoids causing migrating property secondary pollution; Economic benefit and social ecological benefits are remarkable.Simple, economic, the easy row of this law.
Embodiment
(concentration can reach about 90% with high density, being paste) the mud pick is got, e Foerderanlage (model YT series or and SJS series), can make mud be transported to and store up on the spot in the silt target compound with pump (model YT series or and SJS series), for the mud high-efficiency dehydration provides precondition with the alap state of water content; Storing up the silt target compound on the spot is environment-friendly type storage silt pipe bag, its two kinds of ageing resistance polypropylene fibers by special processing (through cold drawn high strength monofilament and the netted silk with high filter property) (are similar to the weave of twill Khaki through the brilliant weave, just looking up and be closely knit zero-clearance in the face of light, obliquely light is looked up then arrangement of apertures is neat) be made into, or the braiding of polyester (polyester) filament fiber forms.Have higher-strength, variable aperture, variable thickness, can bring into play the characteristics of filteration, especially the tiny clay in the mud is had crown_interception; (the pick pipeline of getting delivery system inserted the become silted up about 1m of import of pipe bag of environmental protection storage during city lakebed, bed-silt or Sewage Plant mud also can directly be charged by the pipeline that conveying is got in mud high density pick and become silted up the pipe bag to the environmental protection storage, both are tightened, can be owing to high pressure is unclamped), charge and make double-strength pipe bag dilatational strain and bear elevated pressures.Because pipe bag retraction pressure and charges deadweight effect, the most of water body in the mud are more easily filtered by bagging and are discharged; Because the high filterableness of bagging, the water of discharge can be up to standard substantially, and the soil body then is stored in the bag fixed, 3～5 weeks of consolidation time, be consolidated into the soil body with certain shearing resistance, and can be for utilizing and handling; Because environment-friendly type storage is become silted up the pipe bag than traditional settling tank Duo 4 face sky draining face, because high many of mud concentration ratio conventional apparatus that e Foerderanlage obtains are got in the high density pick, so the shortening of sludge dewatering time is more than 5 times; Again because mud concentration height is saved a large amount of floor spaces than traditional settling tank scheme; In addition, the high overanxious property of pipe bag because storage is become silted up, the water of discharging from bag can not pollute surrounding environment.And remarkable benefit, concrete manifestation
1, main economic benefit
With traditional desilting settling tank Technology, usually remove the thick mud of 0.7m, the area in the pond of the storage mud of required dark 1.5m is greater than the desilting area, a large amount of soils have not only been taken, bring very big negative impact also for surrounding environment and view, and the consolidation time length of the dewatering and coagulating time ratio of mud in the pond in the pipe bag is many.In addition, suction pit also need carry out secondary treatment, costs a lot of money economically.
Environmental protection dewatering and coagulating technology is saved manyly than traditional pond storage silt of digging on the spot.Only saving a sapce charge with a diameter 5m, long 50m storage silt pipe bag treatment capacity is example:
This process program: volume 3925m
3, take up an area of 250m
2Pipe bag area 825m
2, with 30 yuan/m
2Meter needs 2.48 ten thousand yuan, (handles 1m
3The pipe bag expense of mud is 6.3 yuan/m
3), comprise that pipe bag, sapce charge add up to 12 yuan/m in being used in
3
Tradition is dug the pond scheme: the dark 1.5m in pond, 3925m
3Mud takes up an area of 2617m
2, take land on lease only in 50,000 yuan/mu, i.e. 75 yuan/m
2(offset pipe bag floor space 250m
2, take up an area of 2367m more
2, count 17.7 ten thousand yuan, i.e. 45 yuan/m
3), count 50 yuan/m
3
This technology is dug 38 yuan/m of pond depositing technology sludge treatment unit volume cost saving than tradition
3, the sludge treatment amount in 1 year in the whole nation is by 3,000,000 conservative m
3Meter can be saved sapce charge with 1.14 hundred million yuan.
Do not comprise more that more than tradition digs the great expense that the remote slurry conveyed of pool process, concentration of slurry increase than the low several times of this technology.
The silt consolidation time of the remote suction pit precipitation technology of carrying is about 6～9 months.
Above-mentioned greatly relatively conservative huge economy, society and the ecological benefits of more promptly having demonstrated.
In sum, only be: 1.14 hundred million yuan with the economic benefit of saving cost of land every year
2, social ecological benefits
The silt consolidation time of environmental protection dewatering process was about for 3～5 weeks on the spot, avoid the long distance of mud to carry and reach that 6～9 months settling tank dehydrations cause to along the road, the regeneration of contaminated of settling tank surrounding ground resource, groundwater resource.Not only help improving lake, the network of rivers, lake, city and
Water quality of river also can effectively be saved the land resources of a large amount of preciousnesses simultaneously.
The environmental protection dewatering process not only can solve the mud environment protection handling problem on the spot; also can be used as the inner core main body of Hu Di, river levee, the dual environmental and ecological protection effect of having played desilting and having avoided cutting the earth, the Sustainable development of city and suburban countryside is had very far-reaching influence.
The comparison of above society, economic benefit can be referring to following simple and clear comparison sheet 1.
The comparison of this technology of table 1 and traditional technology
| Scheme | Economic benefit (only using tricks) to save land charges | Society's ecological benefits |
| Tradition fortune mud digs pool process | The settling tank sapce charge of offsetting after the pipe bag takes up an area of is 50 yuan/m 3, 50 yuan/m 3* 300 ten thousand m 3=1.5 hundred million yuan | 1, mud is carried along the line the pollution; 2, settling tank takies a large amount of soils; 3, settling tank seepage secondary pollution; 4, dehydration needs 6～9 months. |
| Environmental protection dewatering process on the spot | Pipe bag and sapce charge are 12 yuan/m 3, 12/m 3* 300 ten thousand m 3=0.36 hundred million yuan | 1, local dewatered, need not to carry; 2, local dewatered, take up an area of small; 3, water base of bag filtration of pipe is up to standard; 4, only about 3 weeks of dewatering time. |
| Both relatively | The technical program is saved sapce charge 1.5-0.36=1.14 (hundred million yuan) | 1, the latter does not have the secondary pollution along the line of conveying; 2, the latter does not have stock tank seepage secondary pollution; 3, the latter need not to take a large amount of soils; 4, latter's dewatering time only needs 1/5. |
Annotate: 1, in the table only in annual desilting amount 3,000,000 sides in the whole nation; The desilting amount is big more, and benefit is obvious more.
2, do not count a large amount of expenses of the increases such as a large amount of settling tank areas that the traditional scheme long distance is failed mud, concentration of hydraulic mixture is low and increase; Do not count simultaneously the short enormous benefits that produces of present technique processing cycle.
