Abstract

The invention relates to a novel periphyton sampler, which mainly comprises a supporting frame structure formed by organic glass materials, a fixation matrix formed by glass slides, a buoyancy carrier formed by foam plastic boards or fixed facilities formed by timber piles and the like. The sampler is mainly used for the relevant study and monitoring in the aspects of natural water bodies, artificial wet land and the like, plays an important role in the aspects of administration of lake eutrophication, ecological restoration, sewage treatment and the like, and has the prominent advantages of simple design, convenient operation, economy, safety and practicality.

Description

A kind of novel periphyton sampler

Affiliated technical field

The present invention relates to a kind of novel periphyton sampler, be used in natural water body, artificial swamp sessile organism sample collecting, its outstanding advantage is simplicity of design operation, easy to operate, economic security practicality.

Background technology

Natural water bodies such as lake are carrying out eutrophication control and restoration of the ecosystem, often relate to the wherein research and the monitoring of sessile organism group; Biosafety evaluation in the water bodys such as river also often relates to sessile organism group wherein; The structure of artificial swamp, the assessment of treatment effect etc. also need sessile organism structure of community, biomass in the system are carried out quantitative assessment, carry out the sample that these work all need sessile organism in the acquisition system.The method of PFU is adopted in the collection of sessile organism mostly traditionally, because the restriction in aperture on its employed sponge, part biology can't enter set, it also only is that tramway type suspension equip ment is in water body in addition, accuracy to sample collecting and processing all has certain influence, and it is, also cumbersome in the operation because the standard of handling between the different users often also is difficult to unification.

Summary of the invention

Task of the present invention is, designs a kind of supporting structure of framework, is used for the fixing of fixation matrix, reduced fixation matrix influencing each other in water body on the one hand, is convenient to putting into and taking out of fixation matrix on the other hand.

In the conventional P FU method, what the matrix of set usually adopted is sponge, and under normal operating condition, various biologies in its surface or enter its inner set in the water body.Yet owing to still do not have a standardized product at present, the defective of the material that different in addition users adopts in the process of using itself and the disunity on the specification, thus influenced the precision of its sampling.

Task of the present invention is to use a kind of glass slide of standard, substitute the sponge matrix among the conventional P FU, because the unification of material, specification, thereby can avoid because the difference that fixation matrix itself brings, improve the precision of sampling in the experimentation and the comparability of sample.

The method of PFU does not have standardized product traditionally.

Description of drawings

The present invention is further described below in conjunction with drawings and Examples.

Fig. 1 and Fig. 2 are respectively sampling thief synoptic diagram of the present invention and vertical view.

1. CARBURIZING FURNACE FOR STAINLESS FASTENER among the figure; 2. slide glass; 3. securing cover plate; 4. static line hole

Embodiment

Task of the present invention is, the simplified manufacturing technique flow process, and (Da Xiao sampling thief cost is less than 100 yuan as shown in drawings) reduce cost.At first at the pmma material of the strip slide glass pickup groove of getting on the bus out, then with CARBURIZING FURNACE FOR STAINLESS FASTENER 1. or glue the synthetic glass bar is linked into support frame, 2. slide glass is packed in the pickup groove, can pull down then and maybe can turn down cover plate and 3. be fixed on the support frame structure with CARBURIZING FURNACE FOR STAINLESS FASTENER, wear rope through with rope at last and 4. be fixed on floatation device or the spud pile, can carry out sample collecting.

Claims

1. novel periphyton sampler, it mainly is to be made of support frame structure, fixation matrix and buoyancy carrier or fixation means etc.

2. require described novel periphyton sampler as right 1, it is characterized in that, described support frame structure is to be formed by the pmma material of strip bonding.

3. as requiring or 2 described novel periphyton samplers, it is characterized in that, a side active is set, for example can pull down the fixed sturcture that maybe can turn down.

4. as the described novel periphyton sampler of above-mentioned each claim, it is characterized in that described fixation matrix is a slide glass, it is placed in the pickup groove of support frame structure.

5. as the described novel periphyton sampler of above-mentioned each claim, it is characterized in that described buoyancy carrier is large-scale foam-plastic blocks.

6. as the described novel periphyton sampler of above-mentioned each claim, it is characterized in that its main application is sessile organism sample collecting in natural water body, artificial swamp correlative study, observation process, also can be used for other environment, as sessile organism sample collecting in the sewage disposal.
