Embodiment
In order further to explain the technical solution of the utility model, the utility model is elaborated below by specific embodiment.
MSW landfill leachate regulating height monitoring device of the present utility model as shown in Figure 1, comprises ring electrode 1, electric wire 2, sleeve pipe 3, weeper drain 4, high-density resistivity instrument 5.Ring electrode 1 is bundled on the annular groove of sleeve pipe 3, is provided with electric wire 2 in the sleeve pipe 3, after electric wire 2 is electrically connected each ring electrode 1, pass and be electrically connected to high-density resistivity instrument 5 from an end of sleeve pipe 3, and sleeve pipe 3 is enclosed within the plastic draining french drain 4.
Ring electrode can be the annular copper wire of sealing, also can be the C font copper wire that does not seal, and is convenient to like this be fastened on the uniform annular groove of level on the sleeve pipe.Annular groove closes to the notch position slightly, so both can make ring electrode engaging tightr, be difficult for scurrying the position, come off, and guarantee ring electrode fully contact ooze drop liquid in, reduce the ring electrode exposed part, strengthen anti-corrosion function.In addition, when needing to change after the long-term use of ring electrode and electric wire, only need from the plastic draining french drain, take out to get final product.Therefore, the utility model is also very convenient aspect operation and maintenance.
The principle of work of MSW landfill leachate regulating height monitoring device of the present utility model is: sleeve pipe 3 is vertically inserted in the refuse landfills, electric wire 2 be positioned at garbage loading embeading high-density resistivity instrument 4 outside the venue and be electrically connected.The resistivity of oozing the following ring electrode of drop liquid is less than the resistivity of oozing the above ring electrode of drop liquid, monitors the resistivity of ring electrode 1 by high-density resistivity instrument 5, can record the height that oozes drop liquid.
The high-density resistivity instrument has multiple observation mode, can calculate and show resistivity in real time, monitor that resistivity changes in time, the high-density resistivity instrument is electrically connected the uniform ring electrode of level, can record the resistivity of each ring electrode at any time quickly and easily, find out the position of the ring electrode that has notable difference, can real-time monitor the height that oozes drop liquid.
The spacing of ring electrode directly has influence on the monitoring accuracy that oozes drop liquid height, so the layout density of each ring electrode should be higher, and promptly spacing is smaller is advisable, and is controlled at the spacing about 1cm.Consider that landfill yard bottom may not gentlely guarantee that data are reliably comprehensive, should lay monitoring device at a certain distance in refuse landfill; The refuse landfill diverse location ooze drop liquid, its end face should be on a surface level, if monitor to ooze drop liquid end face too high or too low, should reject these data.If it is unusual to meet the individual device Monitoring Data, sleeve pipe should be taken out, repair or replace.
After refuse landfill is closed, utilize rig, and hole depth is less than the garbage loading embeading degree of depth, guarantees that boring can not pass refuse landfill 6 impervious barriers in refuse landfill 6 borings; Plastic draining french drain 4 is inserted in the hole of refuse landfill 6, during insertion, utilize the inclination angle of spirit-leveling instrument monitoring plastic draining french drain 4, to guarantee to remain in the insertion process vertically; After treating that plastic draining french drain 4 inserts landfill yard 6, sleeve pipe 3 is put into plastic draining french drain 4.Because the utility model does not destroy impervious barrier in observation process, can not ooze drop liquid and leak, so can't have influence on the seepage control system of landfill yard in insertion, the monitoring location generation of sleeve pipe.
Ooze drop liquid monitor well or gas collection well if refuse landfill 6 is provided with, also can directly sleeve pipe 3 be put into and ooze drop liquid monitor well or gas collection well,, greatly utilized the convenient rate of existing facility with the supporting use of these monitoring facilitieses.
The utility model also has good antiseptic property.At first, the pvc pipe of sleeve pipe 3 for having good anti-corrosive properties; Secondly, ring electrode 1 is with after electric wire 2 is connected, and rust preventive is smeared on ring electrode 1 top layer, and electric wire 2 top layers are enclosed with plastic insulating layer; Once more, plastic draining french drain 4 skins have one deck geotextile, ooze drop liquid 7 in order to filtration, make that oozing drop liquid 7 sees through plastic draining french drain 4, and impurity such as rubbish are retained in the geotextile outside.
The utility model makes full use of and oozes the drop liquid principle different with rubbish resistivity, has the position of the ring electrode of notable difference by high-density resistivity instrument monitoring resistor rate, obtains oozing the height of drop liquid.Therefore the utility model has solved orthodox excavation method and has determined expensive big, the problem that the cycle is long of MSW landfill leachate regulating, and the utility model investment is little, time saving and energy saving, for determining that the waste landfill site leachate height provides a kind of new approach.
Present evaluation method for garbage leachate, be to set up numeral or dynamic model, or be to carry out laboratory experiment, and these methods are for different garbage loading embeading places, geological hydrology condition, then need seek different models, and it is carried out complicated analysis and solution process.And the utility model is the liquid level that obtains refuse landfill by the uniform electrode of level on the sleeve pipe of vertically placing, and therefore, the scope of application is very wide, applicable to the waste landfill site leachate height monitoring of different garbage loading embeading modes, different sites.Particularly, can find dangerous situation in time, create favourable opportunity for taking the emergency repair measure for large-scale sanitary filling field.
Though, ooze drop liquid characteristic and can influence the resistivity size, to ooze drop liquid and rubbish resistivity and still have big gap, the former is a liquid, and the latter is a solid, and resistivity exists the degree of depth of obvious flex point correspondence to be the degree of depth of oozing drop liquid.
Device of the present utility model is compared traditional monitoring devices such as liquid level instrument, and have the following advantages: (1) data can realize continuous real-time monitoring, and garbage degradation and rainfall can realize continuous real-time monitoring to the influence of oozing drop liquid height; (2) time saving and energy saving, after instrument was laid installation, the automatic data collection record arrived field monitoring without the tester; (3) meet extreme weather and still can monitor, during as rainfall, manually adopt liquid level gauge then to be difficult to field monitoring; (4) data are reliable and stable, and monitoring accuracy is higher, ooze drop liquid monitoring height error and can be controlled within the 1cm.
The foregoing description and accompanying drawing and non-limiting product form of the present utility model and style, any person of an ordinary skill in the technical field all should be considered as not breaking away from patent category of the present utility model to its suitable variation or modification of doing.
