Problems solved by technology

Traditionally, the collection of sessile organisms mostly adopts the PFU method. Due to the limitation of the pore size of the sponge used, some relatively small organisms cannot enter the sessile state. In addition, they are simply suspended in the water body, which affects the accuracy of sample collection and processing. All have certain influences, and because the processing standards among different users are often difficult to unify, the operation is also more troublesome

Embodiment Construction

[0010] The task of the present invention is to simplify the manufacturing process and reduce the cost (less than 100 yuan for the sampler of the size shown in the accompanying drawing). First, car out the glass slide fixing groove on the long strip of plexiglass material, then connect the plexiglass strips into a support frame with stainless steel screws ① or glue, put the slide glass ② into the fixing groove, and then put the detachable Or it can be folded up and the cover plate ③ is fixed on the support frame structure with stainless steel screws, and finally the rope is passed through the rope hole ④ to fix it on the floating device or the fixed pile, and the sample can be collected.

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

Technical field [0001] The invention relates to a novel fixed biological sampler, which is used for collecting fixed biological samples in natural water bodies and artificial wetlands, and has the outstanding advantages of simple design, convenient operation, economy, safety and practicality. Background technique [0002] The eutrophication control and ecological restoration of natural water bodies such as lakes often involves the research and monitoring of the sessile biological communities; the biosafety assessment of rivers and other water bodies also often involves the sessile biological communities; the construction of artificial wetlands, The evaluation of treatment effects also requires quantitative evaluation of the sessile community structure and biomass in the system. To carry out these tasks, it is necessary to collect samples of sessile organisms in the system. Traditionally, the collection of sessile organisms mostly adopts the PFU method. Due to the limitation ...
