Description
Technical field
The utility model relates to tap water biological sampling equipment technical field, particularly a kind of feedwater piping microbial film sampling thief.
Background technology
Along with the continuous acceleration of socioeconomic fast development and urbanization process, drinking water safety problem has caused people's extensive concern.In feedwater links (comprising water source, water factory etc.), water supply network is a weakest ring: even if source quality is good, water factory's output water compliance rate approaches 100%, but due to pipe scale in pipe network and biomembranous existence, can cause biomembranous coming off when hydraulics changes or moves when accident occurs, thereby affect the water quality of water,tap.In feedwater process, in the time that microorganism reaches some amount in water, will be adsorbed in tube wall and form microbial film.Microbial film can bring out wall erosion and fouling, reduces the conveyance power of water of pipe network; Biomembranous aging coming off can cause that user's water quality deterioration, colourity and turbidity rise, and causes water,tap water quality to reduce.Many pathogenic micro-organisms depend on biofilm development, and microbial film is dealt with extraneous disadvantageous life condition for it provides favourable environment.But in the time that hydraulics changes, pathogenic micro-organism likely comes off from microbial film, enters water body, thereby is detrimental to health.In addition, microbial film also easily causes the accumulation of some hazardous and noxious substances, thereby in the time that hydraulics changes, can cause the hazardous and noxious substances of accumulation to discharge into water body and affect the water quality of pipe network.As can be seen here, make kind and the composition of biomembranous characteristic in water supply network and microbial clear, verify the biologically stable of water supply network, for ensureing that drinking water safety tool is of great significance.
Up to now, the domestic research for tap water water supply network biologically stable mainly concentrates on the water body of pipe network, very rare to the biomembranous research of water supply network.Only for actual pipeline, biomembranous sampling is that specific pipeline section is intercepted, and the microbial film in this pipeline section is carried out to sampling analysis, but the method operation must intercept actual pipeline, operational difficulty, spend high, be difficult to promote.For above problem, the utility model has designed a kind of feedwater piping microbial film sampling thief, can gather actual pipeline microbial film easily, and simple in structure, with low cost, be easy to promote.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of feedwater piping microbial film sampling thief and method thereof of easy handling is provided.
Feedwater piping microbial film sampling thief comprises sampling part, thief rod, rubber pad, sampling thief base, sampling thief fixed ring, sampling thief fixed ring is provided with sampling thief base, thief rod is provided with screw thread, on sampling thief base, have the threaded hole matching with thief rod, one end of sampling part is provided with screw thread, the end of thief rod is provided with the threaded hole matching with the part of sampling, and on thief rod, cover has rubber pad.
The cross section of described sampling part is circular, and the outer face of sampling part is identical with the radian of feedwater piping inwall to be measured.
The cross section of described thief rod end is circular, and the cross-sectional area of the described sampling part the other end is identical with the cross-sectional area of thief rod end.
The utlity model has following advantage: the utility model can gather pipeline microbial film under the condition of guaranteeing not affect operating mode, avoided the operation of the loaded down with trivial details costlinesses such as section pipe.In addition, the utility model can arrange according to the difference of actual pipeline the sampling part of unlike material, sampling process does not affect actual pipeline operating mode, and the microbial film that sampling thief obtains is substantially identical with the microbial film at other positions in pipeline, samples representative.Simultaneously can be according to particular cases such as pipe diameter, hydraulics, monitoring indexes, the sampling part of design different area, thereby and gather enough biomasss by adjusting the opening of pipeline adapt to the to sample size of part, ensure the reliability of experimental data.
In to actual water supply network research, the utility model can gather diffraction patterns for biomembrane samples under the condition of easy handling in timing.The sample gathering can be used for bacterium quantitatively, the analysis such as the qualification of microbial population diversity and structure, can be used for studying the biologically stable of water supply network simultaneously.
