Technical field
The utility model belongs to repairs polluted underground water field, is specifically related to a kind of experiment baffling layer-stepping permeable reactive wall.
Background technology
Underground water is the important component part of water resources, is the natural resources of the requisite preciousness of human survival, life and activity in production.As tellurian Freshwater resources, it has the very high ecological value and economic worth.Along with economic society constantly advances, life, the human activity such as industrial, agriculture create a large amount of pollutent, result in groundwater pollution.According to statistics, the Urban Underground water pollutions of China more than 50% is comparatively serious, and most urban groundwater water quality constantly worsens.
For the reparation of underground water, main recovery technique is showering and in-situ immobilization.Compare traditional dystopy facture (as pump-and-treat system method), belong to permeable reactive barrier (the PermeableReactive Barrier of in-situ immobilization; Be called for short PRB) technology without the need to additionaling power, have treatment effect good, multiple pollutant can be processed simultaneously, process timeliness is long, working cost is low etc. advantage, be widely used.But it is perfect that this technology still has some shortcomings to need: (1) is exist with the form of compound due to pollutent mostly, so need multiple reaction filler Combined Processing pollutent, brings inconvenience like this to adding medium in construction process; (2) in order to increase the time that reaction filler and pollution substance reacts, the method for reacting depth of packing or multiple reaction wall of connecting with increase is usually needed, thus the difficulty of increase actually operating and running cost; (3) PRB adsorption after operation for some time may reach capacity inactivation then, or reaction gained throw out blocks, and affects the normal operation of PRB, at this moment needs reaction wall to dig out to carry out processing or change reaction filler.
Existing permeable reactive barrier structure, primary focus has been placed on selection and the proportioning of filler, the method for device water inlet and water outlet, in the problems such as the discovery of new packing, proposed, but solution is very few for problems such as whether reaction are abundant, reaction results in blockage.
Utility model content
The purpose of this utility model is to provide a kind of experiment baffling layer-stepping permeable reactive wall, to overcome the defect that above-mentioned prior art exists, the utility model solves the problems such as reaction is insufficient, reaction results in blockage, thus further improve the treatment effect of permeable reactive barrier, reach the reparation to Polluted Groundwater.
For achieving the above object, the utility model adopts following technical scheme:
A kind of experiment baffling layer-stepping permeable reactive wall, comprise body of wall, the top of body of wall is provided with water-in, bottom is provided with water outlet, described water-in connects the sample plasma bottle for holding Polluted Groundwater by pipeline, pipeline is provided with pump, some water-stop sheets are provided with in body of wall, between water-stop sheet, some cavitys for placing response filler are formed between water-stop sheet and the top of body of wall and between water-stop sheet and the bottom of body of wall, each water-stop sheet all has side to be provided with some drainage holes, described some water-stop sheets are crisscross arranged, form a top to be communicated with water-in, the S shape path that bottom is communicated with water outlet.
Further, pipeline is also provided with under meter, according to water (flow) direction, described under meter is located at the rear side of pump.
Further, the quantity of water-stop sheet is 4.
Further, body of wall is rectangular structure, and water-stop sheet is rectangle structure.
Further, body of wall is cylindrical structure, and water-stop sheet is circular configuration.
Further, pump is peristaltic pump.
Further, the both sides of body of wall are staggeredly equipped with some thief holes, and thief hole is all located at the top that water-stop sheet has drainage hole side.
Compared with prior art, the utility model has following useful technique effect:
The utility model is relative to traditional reaction wall, owing to rationally arranging the drainage hole on water-stop sheet and water-stop sheet, make that the Polluted Groundwater that flows through is S-type flows through each layer reaction filler, considerably increase pollutent and the reaction times of reacting filler, react fully and carry out, can avoid between filler mixed in together due to washing away of the water yield, affect treatment effect, mutually split between each reaction filler, contribute to the saturated situation of inspection reaction filler and be convenient for changing reaction filler, compact construction is simple, make full use of space, be applicable to all fillers and pollutant type.
Further, the flow of pumping Polluted Groundwater can be obtained by arranging under meter, while ensureing purge amount, ensureing the treatment effect of permeable reactive wall.
Further, by arranging thief hole, sampling can be carried out to the current through reaction filler easily and detecting, monitoring the treatment effect of each layer reaction filler at any time.
