Description
Technical field
The present invention relates to environmental technology field, and in particular to the collection of microorganism in water sample.
Background technology
Method using microbial treatment water pollution in water body is as follows：Microorganism in water body is collected, carries out laboratory culture,
Put into again in water body, increase the population number of microorganism in water body, and then increase microorganism and aquatic animals and plants and pollution in water body
The contact frequency of thing, efficient degradation organic matter, degradation of ammonia nitrogen and total nitrogen；It is aided with ecological floating island and submerged plant, transfer, decomposes always
Phosphorus, promote aquatic ecosystem structure, progressively recover self-purification of water function.
The content of the invention
Technical problem solved by the invention：How indigenous microbes in water body are collected.
In order to solve the above technical problems, the present invention provides following technical scheme：Microorganism-collecting device in a kind of water sample, bag
Include the string bag of taper and the collection funnel of taper；The string bag is linked together with collection funnel by flexible member；The bottom of the string bag
Provided with an opening, the elastic switch valve in the string bag makes the opening be in normally off；The bottom of collection funnel is provided with
Upper head part；When collection funnel is set in the outer surface of the string bag, the elastic switch valve is driven on top to the upper head part upwards, makes the string bag
Connected with collection funnel.
By above-mentioned technical proposal, the operation principle of microorganism-collecting device is as follows in described water sample：String bag remains stationary,
Operator pulls collection funnel, flexible member stretching, extension, and collection funnel departs from the string bag；Afterwards, the water sample fetched is poured into the string bag
Interior, water is filtered out from the string bag, and the microorganism in water body is deposited on string bag wall；After whole water sample filterings, operator pulls
Collection funnel, in the presence of flexible member elastic force, the string bag is combined together with collection funnel, and collection funnel surrounds the string bag, is received
The madial wall of collection funnel fits together with string bag lateral wall, and the upper head part of collection funnel is inserted upwardly into string bag bottom opening, will
Elastic switch valve top is opened, and the string bag connects with collection funnel；Afterwards, operator rinses string bag inwall with pure water, is leaked due to collecting
The stop for the side wall that struggles against, the microorganism on string bag wall are gradually collected to the bottom of collection funnel, and the foot passage through collection funnel
And it flow in corresponding vessel.
The beneficial effect of microorganism-collecting device is in water sample of the present invention：Taken after being filtered to sampling water body
Microorganism therein is returned, it is convenient and swift, microorganism will not be caused to lose, improve sample collection efficiency.
In above-mentioned technical proposal, " the elastic switch valve being arranged in the string bag makes the opening be in normally off " refers to,
In the case where being acted on without external force, elastic switch valve seals the opening.
The collection funnel includes funnel body and collecting pipe, and funnel body bottom offers through hole, and the through hole is with collecting
Pipe connects；The upper head part is arranged on the connectivity part of collecting pipe and above-mentioned through hole.The string bag is shaped as taper, the shape of collection funnel
Shape is taper, and both coordinate, and can make to be arranged on collecting pipe and the upper head part of above-mentioned through hole connectivity part inserts string bag bottom exactly
It is open and pushes up and drive elastic switch valve, after elastic switch valve is pushed up out, string bag bottom opening connects with collecting pipe, is easy to micro- in the string bag
Biology is come together in collecting pipe.
The upper head part is the conical pipe of a hollow out, and the conical pipe top diameter is smaller and base diameter is larger, in convenience
Head part is inserted upwardly into string bag bottom opening.The hollow out design of conical pipe, can be such that the microorganism in the string bag is flowed into by conical pipe
Collecting pipe.
Cross bar that the elastic switch valve includes being fixed in the string bag, activity are plugged in montant on cross bar, installed in perpendicular
The elastic valve body of bar bottom；The top of montant is provided with lateral flange, and spring is arranged with montant, and spring is located at lateral flange and horizontal stroke
Between bar, the top of spring is connected with lateral flange, and the bottom of spring is connected with cross bar, described in the presence of spring force
Elastic valve body is pressed in the side wall of string bag bottom opening, and seals the opening.Through hole, the montant activity are opened up on cross bar
Coordinate in the through hole.The elastic force of flexible member is more than the elastic force of spring, in this way, when the string bag and collection funnel coordinate, upper top
Part can overcome the elastic force of elasticity and jack up elastic valve body upwards.
The spring element is elastic threads, and the quantity of elastic threads is two；The top of two elastic threads is connected to the string bag
On top edge, two elastic threads tops are on string bag top edge at a distance of 180 degree；The bottom connection of two elastic threads
On the top edge of collection funnel, two elastic threads bottoms are on collection funnel bottom margin at a distance of 180 degree.Work as net
When pocket filters water sample, the askew side in the string bag of collection funnel, to filter water sample without prejudice to the string bag.
