Technical field
The present invention relates to tap water biological sampling equipment technical field, particularly a kind of feedwater piping microbial film sampling thief and method thereof.
Background technology
Along with the continuous acceleration of socioeconomic fast development and urbanization process, drinking water safety problem has caused the extensive concern of people.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 is close to 100%, but due to pipe scale in pipe network and biomembranous existence, biomembranous coming off can be caused when hydraulics changes or runs when accident occurs, thus affect the water quality of water,tap.In water supply process, when microorganism reaches some amount in water, tube wall will be adsorbed in and form microbial film.Microbial film can bring out wall erosion and fouling, reduces the conveyance power of water of pipe network; Biomembranously agingly to come off, user's water quality deterioration, colourity and turbidity can be caused to rise, cause water,tap water quality to reduce.Many pathogenic micro-organisms depend on biofilm development, and microbial film provides favourable environment to deal with extraneous disadvantageous life condition for it.But when hydraulics changes, pathogenic micro-organism likely comes off from microbial film, enters water body, thus is detrimental to health.In addition, microbial film also easily causes the accumulation of some hazardous and noxious substances, and the hazardous and noxious substances accumulated can be caused when hydraulics changes to discharge into water body thus affect the water quality of pipe network.As can be seen here, make kind and the composition of biomembranous characteristic and microbial in water supply network clear, verify the biologically stable of water supply network, guarantee 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 is intercepted by specific pipeline section for the biomembranous sampling of actual pipeline, carries out sampling analysis to the microbial film in this pipeline section, but the method operation must intercept actual pipeline, operational difficulty, spend high, be difficult to promote.For above problem, the present invention devises a kind of feedwater piping microbial film sampling thief, can gather actual pipeline microbial film easily, and structure is simple, with low cost, is easy to promote.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, 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 member, 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, sampling thief base has the threaded hole matched with thief rod, one end of sampling member is provided with screw thread, the end of thief rod is provided with the threaded hole matched with sampling member, and on thief rod, cover has rubber pad.

The cross section of described thief rod end is circular, and the cross-sectional area of the described sampling member the other end is identical with the cross-sectional area of thief rod end.
The material of described sampling member is identical with feedwater piping material to be measured.
The feedwater piping microbial film method of sampling is: be fixed on by sampling thief fixed ring outside feedwater piping to be measured, ensure that sampling thief fixed ring and feedwater piping to be measured fit tightly, feedwater piping to be measured is offered the threaded hole matched with thief rod, sampling member screws in the threaded hole of thief rod end, thief rod screws in the threaded hole of sampling thief base and feedwater piping to be measured, sampling member can carry out microbial film sampling to feedwater piping to be measured, when needs are analyzed diffraction patterns for biomembrane samples, the thief rod together with sampling member is screwed out from the threaded hole of sampling thief base and feedwater piping to be measured, sampling member is screwed out from thief rod, sampling member just can be analyzed the diffraction patterns for biomembrane samples in sampling member after taking off.
Tool of the present invention has the following advantages: the present invention can guarantee to gather pipeline microbial film under the condition not affecting operating mode, avoids the operation cutting the loaded down with trivial details costlinesses such as pipe.In addition, the present invention can arrange the sampling member of unlike material according to the difference of actual pipeline, 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, namely samples representative.Simultaneously can according to particular cases such as pipe diameter, hydraulics, monitoring indexes, the sampling member of design different area, and adapt to the size of sampling member by the opening adjusting pipeline thus gather enough biomasss, ensure the reliability of experimental data.
In studying actual water supply network, the present invention can gather diffraction patterns for biomembrane samples under the condition of easy handling in timing.The sample gathered can be used for the analysis such as quantitative, the microbial population diversity of bacterium and the qualification of structure, can be used for the biologically stable studying water supply network simultaneously.
