Suction type membrane filtration suspended particle trap for marine environmental monitoring

Abstract

The invention discloses a suction type membrane filtration suspended particle trap for marine environmental monitoring, and aims to provide a collection device which is convenient to operate, low in labor intensity and high in automatic degree and is particularly applicable to the process of sampling massive monitoring points respectively in different areas. The trap comprises a rack, a water pump, a traction rope, a balancing weight, a water pumping pipeline, a first diversion pipe, a second diversion pipe, a rotating shaft and two mounting casings, wherein the first diversion pipe and the second diversion pipe are fixedly arranged on the rack; the rotating shaft is arranged on the rack in a rotating manner; the two mounting casings are uniformly distributed along the circumference of the rotating shaft; a particle sampling device is arranged in one mounting casing, and a washing diversion device is arranged in the other mounting casing; one end of the water pumping pipeline is connected with the water inlet of the water pump; and one end of the first diversion pipe is connected with the water outlet of the water pump.

Description

technical field [0001] The invention relates to a collection device, in particular to a suction-type membrane filter suspended particle collector for marine environment monitoring for sampling suspended particles in seawater. Background technique [0002] Suspended particles are an important manifestation of the nutritional structure of water ecosystems, and can reflect the potential change trend of water quality in a system, which mainly include suspended sediment, phytoplankton, zooplankton, and humus (organic debris). The suspended particulate matter in the water body of the aquaculture area is an important medium for various pollutants in the water body, and plays an important role in the migration and distribution of various pollutants in the aquatic ecosystem, and plays an important role in the bioavailability and Final destination has an important impact. With the deepening of people's research on suspended particulates in water bodies in aquaculture sea areas, sampl...

AI Technical Summary

Problems solved by technology

The current sampling method not only requires a lot of manual operations, but also has high labor intensity and long sampling period; especially when the research needs to collect suspended particles in different areas, the number of collections is large, the labor intensity is high, and the sampling period is long; and in harsh environments environment, it is even more difficult to operate

On the other hand, the current sampling method can only perform single-point sampling in a small area, and cannot continuously sample suspended particles at different points in a large area. Objectively reflecting the overall level of the waters will cause adverse effects
