Description
Technical field
The present invention relates to ecological engineering technology field is and in particular to a kind of artificial horizontal subsurface flow wetland and its blockage resisting precipitate
Pond and anti-blockage method.
Background technology
By artificial substratum (rubble, gravel etc.) and growth, water plant thereon forms artificial swamp, and sewage is wet
Flow, by a series of process degradation water such as the absorption of substrate, plant absorption, microorganism conversion under the top layer of ground substrate or surface
Nutrient substance, be a kind of matrix-plant-microflora of the uniqueness being different from natural wetland.But due to horizontal drowned flow people
The mentality of designing of work wetland leads to current wetland situation about blocking easily；Align 100 being in operation according to EPA
The investigation that many artificial swamps are done shows, nearly the facility of half all occurred in that substrate clogging problem in 5 years, showed as water
The power coefficient of conductivity reduces, and clean-up effect declines, and service life shortens.It may be said that taking up an area problem except artificial wetland treatment facility
Outward, the blockage problem of artificial swamp substrate has become as the biggest obstacle factor of its application.
In order to tackle the substrate clogging problem of current wetland, domestic and international researcher have also been made more research, is summed up master
Pretreatment to be had, aeration aerating, stop bed and have holidays by turns, change substrate, add Lumbricuss, apply the method such as microbial inhibitor.
(1) pretreatment
Pretreatment can reduce wetland water inlet in float and organic loading (particularly when solid matter in organic loading
When content is larger), the effectively generation of prevention artificial swamp blocking.Common pretreating process has grid, anaerobic precipitation, coagulation to sink
Form sediment etc..Though the time of substrate clogging generation can be effectively postponed in these measures, the substrate that dissolved organic matter leads to can not be prevented
The generation of blocking, and investment, operating cost and the maintenance management difficulty of system can be increased.Need if appropriate for using such method
To change after the operation thus causing and personal expenditures increase and substrate clogging and to be weighed between expense needed for substrate.
(2) aeration aerating
Because anaerobic state is the major reason leading to extracellular polymeric accumulation in substrate, therefore preaeration is carried out to sewage
Oxygenation can play certain prevention ponding.Due to sewage, in process of osmosis, its do value can reduce rapidly, and in aproll
Around pipe, supply air then can effectively improve the do concentration of sewage, maintain the good oxygen condition in substrate, make the decomposition of microorganism
Effect is maintained, and is also prevented from the accumulation of extracellular polymeric in substrate simultaneously.But the system and arranging thing causing increases, operation
Complicated and expense rises, and makes its enforcement also difficult.
(3) stop bed, have holidays by turns
After artificial swamp is blocked, the way abroad passed through is to allow the bed rest and reorganization that stop through several weeks for the bed body carry out recovery section
Point permeability, and the length of phase of having holidays by turns then depends on the weather condition, typically from 7 days to one month.By stop bed stop make with
Crop rotation, on the one hand can make the oxygen in air enter the Organic substance accelerating deposition in matrix degradation inside wetland；On the other hand micro-
The supplement that the various nutrients of biological metabolic requirement cannot continue, the microbes in substrate progress into endogenous respiration
Phase, consume extracellular polymeric or intracellular composition, gradually aging death.But this kind of measure needs to build multiple parallel wetlands constructs
Thing, can increase considerably floor space and the investment cost of wet land treating system.
(4) change wetland fraction matrix
Research finds, the region that blocking is easiest to occur is generally the overlayer matrix near inhalant region, wet with horizontal drowned flow
As a example ground, typically occurred in 1/10～1/4 section before current direction length.For this reason, can be effective by changing wetland fraction matrix
Recover the function of artificial swamp, artificial swamp when shortcoming is that quantities is larger for large-scale wetland, it is difficult to change, changes
Needs stop bed and change length of being taken time.Researcher finds, in the continuous complex vertical current wetland running 5 years, oozes
Thoroughly coefficient declines mainly in the downstream tank near water inlet end, and be reduced by up to is not on wetland top layer, but top layer with
At lower 15～30cm, this exactly proves that substrate turns to anaerobic environment by oxidation environment and easily occurs organic metabolism product to cause
Blocking.But this result of study it is also proposed problem, horizontal subsurface flow wetland is typically designed effective depth in 60～80cm, this meaning
Need such as to change substrate to solve blockage problem, the plant growth substrate that microbial activity is the strongest, root system of plant is the most flourishing will be changed
Matter layer, after so changing Wetland Substrate wetland plant and substrate microorganism will need the long period (it is generally acknowledged that at least 1 year with
On) carry out again maturation to obtain the recovery of disposal ability.
Make a general survey of domestic and international present Research, cause the many factors of artificial swamp substrate clogging, corresponding preventive measure and extensive
Multiple countermeasure is also a lot, but effect difference is very big, and often cures the symptoms, not the disease.Comprehensively get on very well, organic pollution and its metabolite
Be artificial swamp blocking main cause, the solid particle this kind of with organic solid of the mineral suspensions in water inlet can by low become
This pretreatment mode (grid, sedimentation tank, flocculation etc.) is well solved, but long-pending in dissolved organic matter and substrate
Tired microbial metabolic products (including EPS from bacteria etc.) are undoubtedly difficult to even cannot be solved with lower cost technique
Certainly, in a very long time from now on, blockage problem will become the emphasis in constructed wetland waste water treatment technology research.
Content of the invention
In order to solve the susceptible to plugging difficult problem of horizontal drowned flow artificial wet land, the invention provides a kind of horizontal subsurface flow wetland is anti-blocking
Blocking method and sedimentation tank.
Technical scheme is as follows:
A kind of artificial horizontal subsurface flow wetland is it is characterised in that comprise multiple horizontally arranged wetland units, in wetland unit
Between be provided with blockage resisting sedimentation tank；
Described blockage resisting sedimentation tank includes as the pond main body of container and to be arranged in the main body wall of described pond
