Abstract

The invention relates to an in-situ filtration concentration sampling device for suspended substances and belongs to the field of water environment monitoring and research. The in-situ filtration concentration sampling device includes a main body supporting frame, a filter cartridge, a waterproof pressure-resistant cabin with a built-in collection control system, a flow meter, a submersible pump,a water depth sensor, a turbidity sensor, an upper computer and a power supply. The water body enters a filtering device from a water inlet of a check valve at the top of the filter cartridge, the suspended substances are held back in the filter cartridge, and the filtered water body flows out from a water outlet through the flow meter and the submersible pump. A turbidity sensor value in the filter cartridge is used as a control condition for judging whether to stop the filtration, and after the filtration is stopped, a concentrated solution of the suspended substances in the filter cartridgecan be obtained. A stirrer and a flow deflector are mounted in the filter cartridge to form strong convective circulation, to prevent the suspended substances from depositing on the surface of a membrane and forming a filter cake layer, filter membrane blockage is avoided, and sampling time is greatly shortened. By combination of the water depth sensor and the flow meter, quantitative sampling ata designated depth and in-situ enrichment of the suspended substances can be achieved, and concentration multiple is accurately reduced. The device is simple to operate, high in degree of informationand low in cost.

Description

technical field [0001] The invention belongs to the field of water environment monitoring and research, and in particular relates to a device for quickly concentrating and collecting suspended particles in natural water bodies through stirring and diversion to accelerate the filtration speed. Background technique [0002] In January 2012, the State Council issued the "Opinions on Implementing the Strictest Water Resources Management System", proposing to strengthen the protection of drinking water sources. With the in-depth development of industrialization and urbanization, the demand for centralized water supply is increasing, and at the same time, the water quality standards of water sources are getting higher and higher. Suspended solids refer to solid substances suspended in water, including insoluble inorganic substances, organic substances, mud sand, clay, microorganisms, etc. The content of suspended solids in water is one of the indicators to measure the degree of wa...
