An indoor artificial subsurface flow wetland water sample and matrix sample collector

Abstract

The invention discloses an indoor artificial wetland water sample and substrate sample collector, which is composed of a sampling tube main body, a baffle plate and a sample hooking device. The sampling tube main body is provided with a sampling hole, and the inner surface of the sampling hole is provided with a rubber slot; The baffle is composed of an inserting plate, a handle and a connecting rod, and the inserting plate is used for inserting into the rubber slot; the sample filler hooking device is composed of a handle and a sampling hook. The sampling tube of the present invention is convenient to insert into the wetland for sampling and effectively prevents the sample from slipping and losing; the wall of the sampling tube is marked with a scale, which is convenient and accurate for grasping the sampling depth; the upper end of the sampling tube is provided with a handle, which is convenient for the operator to apply force; The slot is equipped with a rubber sealing device. When the baffle is inserted, the inside and outside of the sampling tube are completely isolated. When the baffle is pulled out, the sample can enter the tube through the sampling hole; the sampling hook can be inserted from the sampling tube to the sampling hole to move the outer packing into the sampling tube. Helps in sampling; the sampler is easy to use and easy to operate, and is completely suitable for indoor artificial wetland sampling environments.

Description

technical field [0001] The invention relates to an indoor artificial subsurface flow wetland water sample and matrix sample collector. Background technique [0002] As an efficient water purification facility, artificial subsurface wetlands can effectively control the deterioration of aquaculture water quality. The recirculating aquaculture system based on artificial subsurface wetlands is a new trend in the development of aquaculture models in the future. Therefore, it is an important topic in the field of ecological aquaculture to study the water purification mechanism of constructed wetlands and further study its strengthening technology. [0003] In the research, the indoor artificial subsurface wetland is usually constructed as the research object to increase the stability and convenience of the system, and the collection of indoor artificial wetland water samples and matrix samples is an essential link in the research. However, because the constructed indoor composite...
