It is presently mainly a large amount of to be processed using methods such as Miniature Sewage Farm, wetlands, it is feasible on these method and technologies
, but the upper feasibility very little of economic and management, it is as follows that problem is primarily present according to investigations:
1. sewage load it is general in 500 ton days once, medicament expense typically at 0.5 yuan/ton, the electricity charge at 0.2 yuan/ton,
That is yuan/day of supplies consumption about 350, with corresponding one class of 2 people's labour cost relatively under, do not reach scale and benefit, plant maintenance is difficult,
Sewage plant is caused to be difficult to longtime running.
2. the labour cost that wetland need not be higher, but because rural area rubbish and rainwash belongings are more, become silted up
Plug is serious and needs high-tech and mechanical assistance, de-referencing problem in bad repair after generally existing wetland 2-3, especially with undercurrent when clearing up
Wetland Type is the most serious.
3. Sewage Disposal cost is general at 1 ton 2,000 yuan, 500 yuan of wetland 1 ton but takes up an area big, and land percolation system is cheap
But take up an area huge.
That is:There is management, fund and manpower short slab in rural sewage treatment existing method.At the same time, rural area soil
Ground ecological protection problem is serious:Land pollution is more serious, and it is big that ecological crops obtain difficulty;Soil erosion is more serious, side
The ecological revetment in slope, mountain region etc. lacks, and compares the focus of concentration in beautiful rural area builds.Beautiful rural area is generally with ecology scape
It is economic support to see with ecology agriculture and animal husbandry output, but is technically generally difficult to ensure blue mountains and green waters at present, often only by a large amount of
Investment is ensured with the density of population is cut down, it is difficult to long term support.
In existing waterway improvement, often there are the method for directly delivering flocculant, such as G20 period river course emergency processings.But this
The problems such as kind of method flocculant sinks to the bottom, breaks up is serious, pollutant and disengaging water body not yet in effect, increases the load of bed mud, theoretical
Go up and do not apply to.
In consideration of it, the present inventor carries out in-depth study to above mentioned problem, there is this case to produce then.

It is dry, dried flocculate is used for ecological afforestation or crop-planting.The prominent variation of the solution of the present invention be form it is small
Type river course is purified --- catching deposit is used for the water of planting industry resource ---, and soil couples ecological engineering circulation technology, using wadding
Solidifying body catches part and organic pollution and mineral is caught in water body, and transferable disembarkation carries out microorganism aerobic fermentation and as plant
Thing planting matrix, if necessary after the material that is captured is consumed, still can reuse water body, it is achieved thereby that water harnessing --- sludge provide
The circulation in source.It is that microturbulence seizure equipment does not catch stone, large-scale rubbish with the prominent variation of traditional dredged sediment resource
In rubbish, and flocculate microorganism be substantially at it is aerobic with and oxygen condition be difficult it is corrupt smelly, it ensure that floccule body can debark
Dry --- the reliability of planting matrix.The solution of the present invention fixed investment is relatively cheap, it is not necessary to concrete management, and utilizes sludge
It is quite practical in the few place of the industrial pollution such as non-industrial city, rural area for ecological afforestation and crop-planting.
Used as a kind of preferred embodiment of the invention, may move microturbulence and catch equipment is objective case cage, and objective case cage is built with net
Pocket, equipped with being used to catch the capture material of floccule body in the string bag, the bulk density of capture material is in 0.01-0.5 tons/cubic meter.
When using, the string bag using loose-fill fibrous material is to catch part as water body flocculate, to load the objective case of the above-mentioned string bag
Cage constructs the traditional water conservancy parts such as ground sills, groynes, longitudinal dike, islands and reefs, riverbed bed course as the equipment of seizure;Or it is simply direct
The two sides in river are fixed on by series connection method.Fibrous material mainly selects vegetative fiber, stalk, withe leaf etc. and its is modified
Material, it is possible to use such as glass fibre, basalt fibre, rock wool fibers are mixed with, to form local microturbulence, with viscous
Attached floccule body and growth mycoderm.Needing the parameter of control is:Bulk density usually required that in 0.01-0.5 tons/cubic meter, so as to
Lower drag is permeable, and ensures certain density can internally to grow up with aerobic fermentation and root system of plant after taking out part.Catch
Catch part and meet microturbulence formation requirement, while meet sludge aerobic fermentation supports requirement with plant.
Preferably, and oxygen or aerobic atmosphere under flocculate is collected, with avoid flocculate ferment drift or on
Smelly burning root after bank, and oxygen or aerobic atmosphere construction can using physical lung series (for example with the patent of invention of Chen Kaihan etc.,
Such as the patent in Authorization Notice No. CN 102249429B) create, by adjusting dam body and oxygen and good to dam body entrapped air

Technological requirement but weight is larger, is technology that time first-class raw material substitution technology or long period side replace filler.
Used as a kind of preferred embodiment of the invention, the flocculant is organic flocculant, inorganic flocculating agent and biological wadding
One or more in solidifying agent, in flocculant input water body so that it is dense that the polyacrylamide consumption in flocculant reaches water body
Degree 1-20ppm, has both aluminium ion or zirconium ion, titanium ion requirement consumption associated with polyacrylamide friendship and reaches water body concentration 0.5-
50ppm so that floccule body is converted into low degradation speed and the multivalent metallic ion crosslinking polyacrylamide with water retention property is wadded a quilt with cotton
Solidifying body, forms multiple metal ion --- and polyacrylamide super absorbent resin can meet floc strength, water-retaining property, plant children
The stability of seedling stage necessary 3-6 month.Though being unsatisfactory for cross linking conditions can be used, floccule body was easily decomposed in several days to be caused
Floccule body capturing efficiency is decreased obviously, and the floccule body hung is difficult to be stored in certain hour on capture material, it is necessary to extremely frequent
Capturing element is changed, so as to lose practical value;Subsequent seizure part is also difficult to meet water retention property in Land_use change, no
Beneficial to plant growth, this is to use the different place of existing common knowledge from flocculant.Above-mentioned medicament may be selected directly in water body
Release, or the pre- string bag for being dipped in the treated loose-fill fibrous material of proper technology.When water velocity is slower, can aid in
Flow pulling equipment flows water.
After floccule body seizure is more, can be taken off at any time, after appropriate placement a couple of days dries, for flowers or vegetables plantation, side
Slope is afforested, now using phosphorus nitrogen organic, microorganism, various algae, the multivalent metallic ion crosslinking poly- third enriched in floccule body
Acrylamide super absorbent resin, supplies plant and uses after extra supplement part mineral element;Using fiber elasticity higher and thoroughly
Gas is come the requirement of machinery and wind damage after meeting part tolerance current scour, carrying, debarking.Certainly it is also flushable to fall to flocculate
Thing is separately collected.
If necessary, will can consume nutriment floccule body catch part be reentered into river course in reuse.
Specific embodiment
In order to technical scheme is explained further, it is described in detail with reference to embodiment.
Case study on implementation one:
The beautiful mountain village river course in Quanzhou Yongchun is muddy to black, it is known that be usually sanitary sewage and chicken and duck breeding wastewater, flood season
Changes in flow rate is larger, it is known that is directly released into water using aluminium polychloride and PAMC and has little effect.
Load the loose string bag, kilogram/cubic decimeter of loading density about 0.05 using local discarded object tea stalks, leaf of bamboo etc..
It is placed in the river course for installing objective case cage (a kind of wire mesh cage, iron wire has plastic-coated) in advance and forms submarine bar.According to fluid meter
Calculate result and build submarine bar three.
Use poly-ferric chloride using the preceding a small amount of aluminum sulfate of doping as flocculant above river course, added by flexible pipe
River course, nearby using the above-mentioned loose string bag it is scattered hang over flow-disturbing in river course and promote it be well mixed with water.Now water body black disappears,
The small floccule body of a large amount of brown colors is produced to be flowed with water.Flocculant usage (contains mass concentration according to conventional sewage treatment consumption
The aluminum sulfate of 0.03% poly-ferric chloride+mass concentration 0.01%), aluminum ions water body concentration is 0.5-50ppm, polypropylene
Acid amides must separately add with ferro-aluminum flocculant, and dosing content reaches water body concentration 1-20ppm, be arranged on from plus ferro-aluminum flocculant at
To first dam about 3-5 minutes.
A large amount of floccule bodys are trapped within the one the second two loose submarine bars after dosing, and the 3rd dam is seldom retained, water body
It is limpid, medicine is hung for three days on end to be found floccule body and undecomposed disappearance and largely put aside.The string bag is changed, under the floccule body brush that will be enriched with,
Mix a little soil and be placed on streamside voluntarily ferment in the open Planting Fast-growing flowers and vegetables after 20 days, observation in 2 months finds that effect is substantially excellent
In general soil;String bag band floccule body and fiber are directly placed on streamside voluntarily direct Planting Fast-growing flowers after ferment in the open 20 days
And vegetables, find within 2 months that tendril class and pionner class such as Bermuda grass, eleusine indica, heronsbill, Yun Zhu, capsicum etc. are feasible, but need
Want the kind such as pakchoi growing way of a large amount of fertile soil properties bad, the easily lodging such as tall plants such as three-coloured amaranth, but such culture medium water conservation
Property is significantly better than that Soil Surrounding.Fully floccule body is consumed totally substantially on the string bag after plantation 6 months, and shrugging off can reuse after impurity
Permeable submarine bar is rebuild in objective case cage.In view of greening usually using the good plant of resistance, it is believed that be suitable for
The culture medium that greening is used, but to being had certain limitations as greengrocery culture medium.
Rainy day can take the string bag away, since it is observed that the presence of the permeable submarine bar has certain influence on flood discharge, but it is substantially low
In traditional solid submarine bar, objective case cage is without hindrance to flood discharge after taking the string bag away, can also retain and catch large-scale floating object.
Find that such as not timely removal string bag then there are a large amount of micro- lifes after forming physical lung to the permeable submarine bar timing aeration
Thing and small fish survive around permeable submarine bar, and downstream water quality slightly has improvement, in the similar ocean of its function the characteristics of Coral Reef Region,
Possesses fabulous ecological protection function.Experiment takes into account the improvement in small-sized river course by showing only one student's sparetime simultaneously,
To landscape without substantially destruction.
The case is prolonged application case.
Case study on implementation two:
The green alga outburst less stationary river course of Quanzhou suburbs one.Using monkey grass, rice straw etc. impregnate high concentration sun from
It is placed in the string bag after sub- polyacrylamide solution, is connected after exacerbation, be fixed in water across river two sides, two horizontal strings is used as one
Group.
The motion of urban river water is promoted using impeller apart from string bag certain distance, while delivering sulfuric acid in front of impeller
Magnesium, aluminium polychloride mixture solution, limewash etc., it is desirable to which aluminium ion amount reaches water body concentration 1-20ppm, magnesium sulfate consumption is big
It is approximately the 0.05% of river, lime consumption is required to meet water body PH 9 or so.Now water body forms a large amount of dirty-green floccule bodys,
A large amount of green algas and the river bed mud scum washed away up by impeller are contained in the inside, and the overwhelming majority is shifted onto the string bag in horizontal string river course by current
On, and on the fiber for sticking to the string bag that is captured, very few sinking river bed.
The method can be used for river course green alga or bed mud lash-up recovering, and effect is quite excellent, when green alga is caught with mud scum, due to weak
The presence of alkaline water body and calcium ion, water systems'phosphorus is largely passivated simultaneously, and a little floccule body that sinks is right because containing a large amount of mineral matters
Remaining bed mud is passivated simultaneously.Green alga is not apparent from recurrence after improvement, and effect is substantially better than existing direct use impeller and gathers
Close aluminium chloride Emergency management blue-green algae green alga outburst river course case.
After taking out the string bag, after directly and placing two weeks after soil mixing, used as periphery greening soil, there is obvious getting fat
And water retaining function, compared with control group, afforestation effect is significantly improved.
Product form of the invention is not limited to the present embodiment, and anyone carries out the appropriate change of similar thinking to it or repaiies
Decorations, all should be regarded as not departing from patent category of the invention.
