Description
Technical field
The utility model relates to inner-walls of duct biological detection device, specifically, is a kind of pipeline biological film sampling apparatus that is used for the biomembranous coenosis of the inside pipe wall of water supply network, inside pipe wall burn into precipitation and sticking dirty species analysis.
Background technology
Tap water after water supply plant is handled is transported in user's the process through water transfer pipe network, owing to still have biodegradable nutrition (organism, nitrogen, phosphorus etc.) in the water, be not sterilized the bacterium that bacterium that agent kills fully or other approach enter water supply network in the output water and can utilize the biodegradable organic in the water to regrow, the part bacterium forms microbial film (Biofilm) attached to utilizing the nutraceutical matrix growth on the tube wall at random.The growth and breeding of bacterium is included in the aqueous solution suspension growth and in two kinds of forms of inside pipe wall apposition growth in the water supply network.Because tap water belongs to the poor environment of nourishing and growing, bacterium is preponderated more than suspension growth at the apposition growth of tube wall, promptly forms microbial film.Microbial film is microorganism, microorganism secretion thing and microorganism chip and the organic complex body that is adsorbed.The regrowth of suspension bacterium in the pipe network has been controlled in adding of sterilizing agent to a certain extent, but very limited for biomembranous control effect.Biomembranous existence can cause problems such as water quality on the water supply network tube wall, comprise rising, the corrosive pipeline of growth, colourity and the turbidity of pathogenic bacterium the dwindling of aggravation, water-carrying section, the generation of booster, energy consumption increases and conveyance power of water reduction etc.All be reported in both at home and abroad and detect pathogenic bacterium and conditioned pathogen in the feedwater piping microbial film, so the biomembranous growth of pipe network constitutes a threat to safety of drinking water.Analyzing the biomembranous main composition of tube wall is that research tube wall microbial film also is a most basic step to most critical in drinking water safety influence, pipe network biofilm development characteristic and the measure of control.
The biomembranous influence factor of tube wall is a lot, comprises quantity, water temperature, pipeline section material and the working life etc. of suspended bacteria in the concentration, water of waterpower factors such as nutraceutical matrix concentration in the water, flow velocity, sterilizing agent.But up to the present, relevant research still is in the junior stage, because biomembranous sampling research is relatively more difficult in the actual water supply network, and in a normal water supply network of operation microbial film small-sized stable ecosystem often, be difficult to the biomembranous generation of reality, development and changing conditions are carried out the complete and effective monitoring.
In order to realize the control to tube wall biofilm development process and growth conditions, two kinds of analogy methods of main at present employing are carried out: a kind of for being similar to the pipeline simulator of actual pipe network, another kind is the littler reactor simulation system of scale.The domestic experimental installation that is used for simulating actual pipe network microbial film forming process is mainly ring-type microbial film lacing film reactor (BAR), i.e. second kind of analogy method.The various countries scientist has also utilized BAR to carry out microbial film mensuration, and microorganism cells stripping means, microbial film morphological structure, biology can assimilate the research of organic carbon (AOC) and biodegradable dissolved organic carbon (BDOC) and biofilm biomass dependency.But ring-type microbial film lacing film reactor (BAR), just the lacing film that hangs with by rotor provides the microbial film apposition growth, rotor is rotation under driving, produce shearing force between the interface of lacing film and water body, simulate hydraulics in the pipe network with this, the size of shearing force is by regulating motor speed control, therefore, its simulated conditions differ greatly with waterpower, the condition of water quality of experiment in the pipe network, especially aspect the condition of water quality simulation, and be unrealized circulating truly of current.And can't simulate actual ducted hydraulic pressure and hydraulic detention time to the biomembranous influence of pipeline.
The utility model content
The purpose of this utility model provides a kind of biological membrane biological situation in the actual pipe network can really simulated, pipeline biological film sampling apparatus simple in structure, easy for installation.
The utility model is achieved in that the pipeline biological film sampling apparatus, comprise body, sampling groove, sampling plug and microbial film slide glass, at least one sampling groove is arranged on the body, sampling groove is connected with tube cavity, the external port of sampling groove is provided with the sealing of sampling plug, and the microbial film slide glass is connected with sampling groove in body.
Described sampling groove can be to be bonded on the body.
Described sampling plug and sampling groove can be threaded fixing.
Described microbial film slide glass is threaded fixing with the sampling plug.
Described on the transverse section of body 1, sampling groove can be provided with six, and the angle between the adjacent sampling groove can be 60 °.
Described body is a pvc pipe.
The terminal relief surface of described microbial film slide glass is provided with surface knurling, with for convenience detach.
The terminal relief surface of described sampling sample plug is provided with surface knurling, with for convenience detach.
It can be installed in the utility model in pipe network model and the actual pipeline easily, and biomembranous sampling and analysing is also relatively easy, by this device, just can monitor biomembranous upgrowth situation in the pipeline in real time, and can investigate different tubing to the film formed influence of biology by changing the material of microbial film slide glass.In addition, also has advantage simple in structure, in light weight, easy for installation.
