Problems solved by technology

[0004] At present, the method of collecting particulate organic matter is relatively simple, mainly relying on the vacuum pump made of glass. This method needs to be carried out indoors (using electricity), and the required supporting tools take up a lot of space, take a long time, and are inconvenient to carry and operate.

Abstract

The invention discloses a portable manual suction filter for collecting particulate organic matters in waterbodies. The portable manual suction filter comprises a sampling device, a sample discharging device and a connecting barrel, a glass fiber filter membrane is arranged between the sampling device and the sample discharging device, and the sample feeding device and the sample discharging device are screwed into the connecting barrel in a threaded manner. The portable manual suction filter can be used for water bodies such as rivers, lakes, reservoirs and ponds, and is convenient to carry, easy to operate and capable of collecting different particle sizes of the particulate organic matters in the water bodies by arranging different pore sizes of glass fiber filters (GF / C or GF / F).

Description

technical field [0001] The invention relates to the field of sewage treatment devices, in particular to a portable artificial suction filter for collecting granular organic matter in water bodies, which is suitable for primary productivity evaluation of rivers, lakes, reservoirs, ponds and other water bodies, as well as biological monitoring and water quality evaluation of polluted water bodies. Background technique [0002] Particulate organic matter (POM) is one of the important components of the aquatic ecosystem. As an important food source for water consumers such as zooplankton, benthic animals, and fish, it can reflect the turbidity and nutrient level of the water body. POM is mainly composed of algae, zooplankton, and debris formed by plant and animal residues. Its composition and physical and chemical properties are affected by factors such as water body type, trophic level, temperature, light, water velocity, and hydraulic retention time. [0003] Particulate organ...
