Description
Technical field
The invention belongs to technical field of sewage, and in particular to a kind of blocking in-situ monitoring of enclosure wall insertion monitoring electrode
Method.
Background technique
Constructed wetland waste water treatment technology is a kind of sewage treatment ecological engineering technology risen the 1970s, by
In having many advantages, such as that flexibility is good, small investment, low energy consumption, dirt-removing power is stronger, convenient for management, without secondary pollution, using increasingly
Generally.However in recent years, artificial swamp frequently occurs the problems such as blocking, purifying property decline, service life in the process of running
Shorten.As in 355 drowned flow artificial wet lands of the U.S. and Britain, nearly half is blocked in using 5 years, and filler waterpower passes
Conductance declines to a great extent, and 80% water flow directly more flows discharge system by bed body surface, and effluent quality deteriorates, and the length of service is by designing
When 50-100 be reduced to 10 years, 5 years even it is shorter；The artificial swamps such as domestic white clay hole, wild goose field, Shatian also occur not
With the clogging of degree.As it can be seen that the blockage problem inside artificial wet land system has seriously affected the lasting, high of artificial swamp
Effect operation.
Currently, it is relatively simple to the research method of artificial swamp generation judgment of clogging, it is all based on the apparent of tracer experiment
Hydraulic detention time（HRT）And residence time destribution（RDT）It studies artificial swamp hydraulic performance characteristics, and passes through artificial swamp
Hydraulic performance determines whether artificial swamp blocks.However the method for this determining blocking is both for artificial swamp entirety
It is evaluated, blocking region accurately can not be forecast and be positioned, cause to be directed to when administering blocking
Artificial swamp integrally carries out replacement filler or dredging, time cost height, deficiency in economic performance.Therefore, for artificial swamp bottleneck area
The accurate monitoring in domain is a problem to be solved.
So the blocking in-situ monitoring method for monitoring electrode is embedded in the invention proposes a kind of enclosure wall for this problem,
By way of being embedded in electrode band in artificial swamp enclosure wall, the accurate prison of blocking can be realized to the artificial swamp of different size
It surveys.This method is to pass through the electrode band of insertion premised on blocking the resistivity contrasts in filler region and unplugged filler region
The mode of combination of two monitors two strip electrodes with the change in resistance on control section, realizes the Exact Forecast of stopping state.It should
Method has simple design, economy, operational management convenient, provides technical guarantee for the lasting of artificial swamp, efficient operation.
Summary of the invention
The purpose of the present invention is can not accurately monitor blocking region for existing artificial swamp, causes blocking to administer maintenance and do not have
There is the problem of effective technical basis, a kind of, blocking monitoring accurate artificial swamp easy using construction is provided, realizes Manual moist
The method of ground blocking region accurately monitored.
Electrical prospecting in applied geophysics is closely combined together by the artificial swamp with traditional artificial wetland, is filled
Advantage of the two in respective field has been waved in distribution, and efficient resistivity detection method is integrated in traditional artificial swamp.
The specific steps are：
One, the blocking in-situ monitoring artificial swamp of an enclosure wall insertion monitoring electrode, including water distribution area, gathering ground, main body are established
Packing area, water plant, monitoring electrode band, bar shaped copper electrode, connecting wire and long side enclosure wall.Wherein, the four of main body packing area
Week is water distribution area, gathering ground and long side enclosure wall, and water distribution area and gathering ground are opposite, and two long side enclosure walls are opposite；Each long side enclosure wall
2 parallel monitoring electrode bands of horizontal insertion respectively amount to 4 monitoring electrode bands of insertion；Electrode band is monitored respectively apart from wetland
Top and bottom is 20cm；Bar shaped copper electrode is installed, bar shaped copper electrode spacing is 20-100cm, and respectively on every monitoring electrode band
It is connected with conducting wire, main body packing area top kind is implanted with water plant, and the water plant is canna, reed, mullet grass and Chang
One of Pu.
Two, be separately connected with resistivity imaging tool between well be mounted on long side enclosure wall on one side on monitoring electrode band and another
Monitoring electrode band on the enclosure wall of side, resistivity imaging tool carries out resistivity by the bar shaped copper electrode on monitoring electrode band between well
Monitoring, monitoring mode are carried out by the way of the Well-to-well geometrics in applied geophysics.If artificial swamp there is no blocking,
Each section Resistivity Characteristics are similar, and resistivity value difference is little, then it is assumed that are uniform resistances, between two monitoring electrode bands
Resistivity value distribution is more steady；If artificial swamp blocks, the filler hole in blocking region is mostly inorganic matter
Grain filling, and particles of inorganic material resistivity is higher than the resistivity of sewage, so the resistivity of blocking region can be than unplugged area
Domain resistivity is high, and the resistivity between two monitoring electrode bands, which will be distributed in blocking region part, at this time to increase, and can position according to this
The position blocked between two monitoring electrode bands.
Three, it reconnects another set and monitors electrode band（Enclosure wall on one side on monitoring electrode band and another side monitoring electrode
Band pair-wise combination）, realize that the blocking between two monitoring electrode bands monitors according to same way as above, finally realize entire people
The monitoring of work wetland.
The present invention designs simple, economy, operational management conveniently, for the monitoring of artificial swamp blocking region, can fill up people
The blank that work Wetland clogging accurately monitors.The artificial swamp will be tieed up by promoting for the processing of various specifications artificial swamp, operation
Shield and the lasting of artificial swamp, efficient operation provide technical guarantee.
