Description
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 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 guaranteeing 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 present invention 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 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.
