Description
Technical field
The present invention relates to water environment treatments and technical field of sewage, and in particular in a kind of solution ecological management engineering
The method and device thereof of dielectric layer blocking.
Background technique
Since 1970s, as domestic and international pollution of water problem is got worse and is magnified, Manual moist
The ecological managements new technologies such as ground (CW), soil filtration processing system (MSL), artificial rapid infiltration system (CRI) are risen simultaneously in succession
It is used widely.These systems are because of the advantages that its is easily designed, small investment, low energy consumption, effect is good, Operation Administration and Maintenance is simple
And it is widely used in water bodies of rivers and lakes pollution, Small Urban and life in the countryside sanitary sewage and agricultural non-point source pollution, townm refuse
In the improvement and prevention and cure project of pollutions such as percolate disposition, good engineering effort is achieved.In recent years, as these engineerings are long
All there is different degrees of dielectric layer (packing layer or filter layer) clogging, cause base in phase operation and engineering practice, engineering
Matter infiltration coefficient sharply declines, occur Yong water it is short stream, blocking oxygen diffusion, discharge capacity decline phenomena such as, cause ponding stench,
The problems such as mosquitos and flies breeds, running environment deteriorates, so that system stability decline, out water treatment efficiency reduce and service life contracting
It is short.
Blocking for ecological managements engineerings such as artificial swamp, soil filtration processing system, artificial rapid infiltration systems is asked
Topic, is broadly divided into three classes about the research of its blocking mechanism, counter-measure and solution at present:
(1) physics causes stifled mechanism and its countermeasure
Physics cause stifled mechanism mainly have suspended particulate substance deposition, organic matter accumulation, the migration of tiny particles content and these
Mechanical compression effect of the substance under flow action.Corresponding physical counter-measure and method include increase garbage grille and
Preposition treatment process section, change water intake mode and direction, reduction hydraulic loading, packing layer or filter layer wheel have a rest, regularly replace and fill out
Material or filtrate, the periodically measures such as harvesting plant and cleaning impurity rubbish.Such methods are often palliative, may be for a long time
Interruption system operates normally, and later period investment and project amount are larger, and time-consuming and laborious, practical cost effectiveness and application be not high, often falls into
Enter the vicious circle vicious circle of " having blocked up stifled after just controlling, controlling ".
(2) chemistry causes stifled mechanism and its countermeasure
Chemistry causes stifled mechanism mainly to have the pH of water phase in medium, oxidation-reduction potential, conductivity, electrolyte concentration, organic
Object material composition and its chemical property, dielectric surface characteristic, mineral composition and its ingredient, surface charge, ion in solid phase are handed over
It is hyperphoric to change with polymeric precipitation ability etc..Corresponding chemically counter-measure and method mainly apply chemical reagent, such as special
Determine acid-base solution, nitrification inhibitor etc. or sodium hypochlorite melts microbial inoculum etc., killing is killed by chemical measure or inhibits micro- life
Object, the chemical characteristic for changing water solid matter destroy the deposit structure of matter to eliminate blockage problem, these measures can be broken
The stabilization habitat chemical feature that bad system longtime running is formed, the chemicals after adding potential secondary pollution may also occur and ask
Topic influences subsequent water quality safety.
(3) biology causes stifled mechanism and its countermeasure
Biology causes stifled mechanism mainly to have microorganism secretion object (some extracellular polymerics that microorganism secretion generates), humus
(water body carry or plant residue generate), microbial bacterial produce gas, and (mainly packing layer or filter layer be aerobic or scarce anaerobism
The N that nitrification/denitrification of denitrification microorganism generates occurs in section2And N2O, the methane CH that methanogen generates4, vulcanization it is thin
The H that bacterium or sulphur reducing bacteria generate2S etc.) caused by air-resistance phenomenon etc..Corresponding counter-measure and method mainly have addition
Biological enzyme formulation introduces earthworm breeding, adds the modes such as screening bacterium.
Currently, existing correlative study person proposes certain methods for packing layer blockage problem, there is prevention packing layer blocking
Generation measure and method (patent No.: CN101050027A, CN101638264A, CN101708899A, CN101723547A,
CN1970473A and CN102126791A), these methods can only prevent and cannot effectively solve to stemming operation；There is utilization
(CN103387291B, CN108101221A) of enzymatic hydrolysis and ancillary measure, but these method selection enzyme classes are single or excessively
It is complicated, it is sometimes desirable to ancillary measure, it is crucial that added single enzyme, group synthase or complex enzyme are to the requirement of temperature condition
Relatively high, hydrolysis result is very poor and cannot dredge very well stifled if ambient temperature is too low；Have and repairs blocking type using animal earthworm
Drowned flow artificial wet land (CN1923728A), this method can only improve packing layer local stoppages problem, spend the time very long, and earthworm
It is difficult to survive in long-term waterflooding environment；Have using screening bacterium and its generation surfactant (CN105670969A,
CN105776550A method), it is longer the time required to these methods, there is also introducing bacterium competition and adaptability problem, for
The deep layer dielectric layer regulation effect of heterogeneity may be not good enough；Also have and dredge stifled method using vibration face steel plate and ultrasonic unit
(CN103896404B), although middle layer on wetland can be blocked serious inorganic particle and extracellular polymeric, organic by this method
Object etc. is stripped down from filler, but the microorganism Extracellular polymers tamper of these high viscosities, low-density is because of gravity and water flow work
With secondary blocking is caused in the filler hole that can still accumulate in middle lower layer, the recovery situation of porosity is also ideal not enough, simultaneously
The vibration face steel plate that this method uses can only also be suitble to lab scale simulator or the little pilot-plant of area, for large area
Actual motion wetland or diafiltration engineering effort less be applicable in.The above method respectively has its insufficient or disadvantage, it is difficult to
Existing ecological management engineering dielectric layer blockage problem is effectively solved in short time, limits the application of these methods.To understand
The certainly above problem, it is necessary to find it is a kind of it is more simple and effective, can effectively solve the problem that existing ecological management engineering dielectric layer is stifled
The device of plug.
To solve the above-mentioned problems, we are made that a series of improvement.
