Description

A kind of river sewage purifying treatment method
Technical field
The invention belongs to technical field of waste water processing, particularly, relate to a kind of purifying method of river wastewater.
Background technology
Along with advancing at utmost speed of China's economy, southeast production is fast-developing, also brings the pollution to river and destruction problem.Modern ecological science thinks that ecological riverway construction refers under the prerequisite ensureing river course safety, by building the engineering means such as ecological river bed and ecological revetment, reinvent the river ecosystem of a relative natural stability and health opening, can long term maintenance river course species diversity and the eubiosis, the finally ecotopia of structure people's water harmony.
Current, the main method that river sewage is administered comprises (Fig. 1): 1, physical method, such as, dredge bed mud, machinery except algae, diversion erosion and deposition and water transfer etc.2, chemical process, as coagulating sedimentation, add chemical agent kill algae, add molysite promote phosphorus precipitation, add the methods such as lime denitrogenation.3, the ecological biological process of an ecological biological method mainly comprises river aeration reoxygenation, biomembrance process. biological restoration, land treatment systems method, aquatic plant purification method etc.

Aquatic plant purification method is the effluent purification method of the natural purification function making full use of waterplant.The reed etc. in duckweed, wetland is such as adopted to carry out purifying treatment in certain waters scope.But sanitary sewage enter problems such as can producing foul smell, insect and landscape impact, the problems referred to above to be considered when therefore selecting, as selected the position plantation reed etc. in air port under spring and summer.
Summary of the invention
For the weak point that this area exists, the object of the invention is to propose a kind of river sewage purifying treatment method.
The technical scheme realizing the object of the invention is:
A kind of river sewage purifying treatment method, comprises step:
1) plant river course waterplant, comprising: watermifoil, Spiked Loosestrife, circle coin grass, floating heart, Canna generalis Bailey, Scirpus tabernaemontani, Arundo donax, spend that mullet grass, again power are colored in vain, one or more in calamus.
Plantation river course aquatic vegetable, comprising: mater convolvulus, the four seasons celery, romaine lettuce, one or more in green water cress;

Bank kind grass planting is: napier grass, rye grass, Herba Clinopodii Polycephali, oil grass, arabian cron, little water banyan, iron imperial crown, pasture and water, one or more in water orchid.
2) prevention and control of plant diseases, pest control dispenser:
The plant of plantation uses medicament, comprising: copperas solution sprayed 1 time every 4-6 days,
Unslaked lime 15kg every mu, derosal 1kg, every mu is carried out soil disinfection or the control of 50% derosal 0.1-0.125% solution spray, and Trichlorphon and Phosphothion emulsion 0.1% solution, pour after hole is inserted in seedbed with bamboo let.
0.1-0.3% urea 1 is enriched once every 7-15 days, connect and execute 8 times, centre sprays potassium primary phosphate 1 time in every 7 days, sprayed 0.1-0.3% borate 1 time every 8 days, promote that nursery stock is healthy and strong, strengthen winter resistance, the micro-fertile boron of foliage-spray, promote that nursery stock is sturdy, foliage-spray trace element zinc, magnesium, improve plant photosynthesis.
Wherein, adopt plantation, flowers, vegetables, paddy rice equipment be: coil pipe, cystose, floating plate, wireline, PVC manage in vain, one or more in waterproof rope, timber, steel pipe, respectively with cement pillar, timber, steel pipe, connect with waterproof rope, wireline, iron wire etc.
Wherein, described river course is that river or inland river are proper, and large river easily washes out plantation equipment too greatly, and the water surface is wide not to be limit, and so long as not navigating, controls flood, unloading big vast river course can.
Ordinary water level problem: Large Scale Death after many water plant plantings, it is bad that one of them major reason is that water lev el control obtains.During plantation construction operation, due to project not yet completion water body there is no complete retaining, or in low water season in spring, water level is often on the low side.Construction manager it has been generally acknowledged that waterplant can not leave water, and the depth of water is a bit more shallow, and it doesn't matter, often water plant planting is being designed below sea-bottom contour or more than level line.To during retaining or when water level increases to ordinary water level, owing to planting too dark, emergent " is drowned ", and floatingleaved plant leaf can not float the water surface and " suffocated ", and submerged plant crosses weak and " dying of hunger " because of depth of water illumination; Or owing to planting exceed too much from normal water line, emergent is by " drought is dead ".Visible normal water line is the lifeline of waterplant, will give enough attention when practice of construction operation to normal water line.Advise first determining normal water line at the scene with spirit-leveling instrument before plantation construction lofting, the depth of water adaptability when plants configuration using each kind of plant is considered as unalterable quota.
Wave problem: river, river, loke shore abrasion are the natural processes of these water body Favorable evolutions, abrasion alluvial is also the important factor affecting these water bodys life-span.In the succession of nature along with water body, bank slope eases up and sedimentary soil, for the existence procreation of waterplant creates condition, the growth of plant slow down the erosion of water bank, the resistance of succession, but the increasing substantially of organic content in the rotten deposition of plant materials, water, enrich water nutrition, improve aqueous bio amount, say that the succession of waterplant to whole water body is contributive from this angle.
People are slow down the erosion of wave to water front in a vital role of water body bank planting aquatic plants, ensure normal water body environment.Waterplant naturally become solid bank and abrasion this to the focus of contradiction.
In general scope is little for the little water system of business building district and public lawn inside, navigation ban, sluggish flow, water front is washed away, corrode less, little to the plantation growth effect of waterplant.The water bodys such as rivers and lakes bring very large difficulty because stormy waves, ship shape ripple or current wash away rapidly to the plantation of waterplant, existence.As stormy waves and ship shape ripple will directly or be reflected by embankment, directly pat consumingly or shake plant materials, thus make that plant leaf is broken, stem is fractureed, even plant materials is uprooped, even growth affect plant causes its death.Therefore will force investigation during plantation, take when planting disappear accordingly wave, bank revetment reinforcement technical measures according to wave feature, after hydrophyte restoration, emergent can play certain wave damping effect, and its root system also can play the solid bank effect of certain bank protection.
The solid bank of the wave that disappears can adopt multi-form according to different water front and wave intensity etc.For open lake, the water front that weather shore, wave are high can consider that use disappears unrestrained alms bowl, but disappear unrestrained alms bowl offshore back gauge should within 150 meters.Little for lake surface, the little water front of wave can adopt deal pile, mao bamboon stake, and they had not only disappeared wave but also bank admittedly, were good selections.
Planting soil problem: planting soil is the nutrient source that waterplant depends on for existence except floating plant, is again the basis supporting plant materials concerning emergent.The requirement of waterplant to planting soil meets above-mentioned two functions to determine.In general the mud of former water body is ideal planting soil, silt can be filled out in conjunction with the desilting of periphery rivers and lakes to the artificial wetland of new excavation, as mud is difficult to purchase, at the veneer of soil in southern used water rice field, in the north as the higher dry farming layer soil of fertility also can be selected in lack of water rice field.Sedimentation, the sclerosis of certain hour will be given after the planting soil backfill heavy to viscosity.To the wave is high and the water front of hard dykes and dams it should be noted that backfill planting soil very easily fallen by wave erosion.In original water body, during planting aquatic plants, also to consider the growth problem of bed mud, before plantation, bed mud situation must be detected in water.The bed mud on weather shore, hard dykes and dams bank is easily etched, and often lack the growth of soft bed mud, this is totally unfavorable to planting aquatic plants, should adopt the unrestrained measure that disappears in advance, reduces wave, and then backfills planting soil, could plant.
Artificial floating bed various functions is introduced:
Along with people's life development. the living environment for the mankind causes very large impact.Just can find out from the water pollution situation be seen everywhere.In order to improve this problem, manually have developed artificial floating bed.Along with the exploitation of artificial floating bed, the effect that artificial floating bed plays in water body purification. make it really become a multi-functional practical technique.Which does artificial floating bed function have on earth?
One, water body treating instant effect

Three, environmental quality is improved
Artificial floating bed, except administering the effect had clearly to water pollution, also possesses environmental landscape function simultaneously.Artificial floating bed not only can be applied in reparation polluted-water, and pollution treatment is antifouling. can also living environment be beautified.Create a beautiful urban look, the effect of getting twice the result with half the effort can be reached.
The effect that artificial floating bed plays in water remediation and purification and environmental landscape effect. along with generally applying, obtain increasing accreditation.And artificial floating bed development prospect is considerable, it is very practical a kind of engineering.
It is water pollution control type comparatively common at present that biological floating island improves water body environment, first this kind of water pollution control mode rise in American-European state tomb, but in recent years this situation of China be also start fashionable gradually, we can see in a lot of places it being occurred that biological floating island improves the situation of water body environment, especially for the transformation of some large-size lake, this and mode seem very effective.
In a line city coin of China, water pollution control often needs to relate to a lot of problems, common administration way easily causes intermediate water body pollution, so increasing people begins through this with brand-new mode to carry out the improvement of water body environment, and with regard to present case, it is still very good that this improves effect, employs this kind of mode and carry out pollution control of water and often can reach good regulation effect exactly.It is worth mentioning that, although it is all well and good to be that current biological floating island improves water body environment effect, but the real regulation effect wanting to have reached, still real-time observation is needed, if be find in use to have occurred that some special situations also should report in time, water pollutions could be administered fast like this.
The inventive method has the following advantages:
Along with developing rapidly of domestic economy, the agriculture the like waste of industry drops in water, serious pollution is caused to China's water ecological setting, and people are more next interesting high for the cry of improving the ecological environment in recent years, people, for the more next interesting concern of water pollutions, become domestic matter of utmost importance artificial floating island and can improve water pollutions, resource of purifying waste water, adopt a large amount of planting aquatic plants to improve the method for water ecological setting, resource of can effectively purifying waste water.
The circulation of artificial floating island to ecosystem matter and energy serves regulating and controlling effect, effectively can improve the situation of water pollutions.Artificial floating island utilizes floating capacity planting aquatic plants, improves water ecological setting by the physical environment rule of waterplant, and artificial floating island itself can also fix the suspended substance in water simultaneously, reaches potential detoxification.Artificial floating island can not only be improved the ecological environment, can also be used for carrying out ecotoxicology assessment to aquatic pollution and enter that biologic chain biology is backward heaped, retouching and transhipment, have very important implication to the maintenance of plant ecological and the safe and comfortable aspect of people and animals.In water, contaminated degree is different, so just needs different artificial floating islands to improve.Resolve through expert, the waterplant such as lotus, reed can root out to different degree chlorine, the phosphorus of contaminated water body, heavy metal and organic pollutant, and obtains in Sewage disposal and use widely.So different artificial floating islands can be selected to improve different polluted water body.Artificial floating island can improve water ecological setting greatly, allows people tie up to this intimately with natural closing.Water pollutions situation is quite serious at home, believes there has been the improvement that artificial floating island can be very fast.
Artificial floating island is a kind of novel method improving water ecological setting, can be good at improving the ecological environment, and through use for many years, has won accreditation and the favor of broad masses.Artificial floating island can not only be improved the ecological environment, and also has a lot of function simultaneously, below let us understand lower artificial floating island all have those effect.
First artificial floating island has good purification of water quality function. it because of for the purpose of and the difference of object and different. mainly have effect to the water quality of eutrophication.Its purification mechanism with, the purification of water quality mechanism of the littoral vegetation zone of lakes and marhshes has closely similar place.Secondly artificial floating island is the best sound places of fish. it have cover, the effect such as eddy current, feed becomes the good condition that fish are lived.Because raw son has adsorption for mud, can purify water again, many people fasten some ropes below artificial floating island simultaneously, and the floating being used for improving the fish such as carp is laid eggs the structure of bed.In addition, artificial floating island is also the best spaces of living of birds, investigator finds the nest having birds on some artificial floating islands, and Many times people are in order to attract nest on certain birds one island, and the custom of nesting according to birds specially carries out special layout on artificial floating island.Last artificial floating island also has wave absorption function.
