Method capable of accurately determining suspended solids in water quality

Abstract

The invention discloses a method capable of accurately measuring suspended matter in water quality. Use tweezers to pick up medium-speed quantitative filter paper, move it into an oven, dry it at 103-105°C for half an hour, take it out, put it in a desiccator and cool it to room temperature, and call it Weight, repeated drying, cooling, and weighing until the weight difference between the two weighings was ≤0.2mg, folded the medium-speed quantitative filter paper with constant weight into the funnel, put it into the Erlenmeyer flask, and measured the fully mixed and uniform sample Filter 50mL of the sample to make all the water pass through the filter paper. After stopping the filtration, move it into an oven for drying at 103-105°C for one hour, then move it in and out, let it cool to room temperature, weigh it, and repeat drying, cooling, and weighing until The weight difference between the two weighings is ≤0.4mg. The principle of the method is simple, and it can accurately measure the quantity and type of suspended matter in the water quality, determine whether the water quality meets the drinking standard for human body, and protect people's health.

Description

technical field [0001] The invention relates to a method, in particular to a method capable of accurately measuring suspended matter in water quality. Background technique [0002] Suspended matter refers to solid matter suspended in water, including insoluble inorganic matter, organic matter, silt, clay, microorganisms, etc. The content of suspended solids in water is one of the indicators to measure the degree of water pollution. Suspended matter is the main cause of water turbidity. The organic suspended solids in the water body are prone to anaerobic fermentation after deposition, which deteriorates the water quality. China's comprehensive sewage discharge standards are divided into 3 levels, which stipulate the maximum allowable discharge concentration of suspended solids in sewage and wastewater. Suspended substances in water are particles with a particle diameter of about 10-4 mm or more. Visible to the naked eye. These particles are mainly composed of sediment, ...
