Abstract

The invention provides a filter membrane assembly and a filter device with the same. The filter membrane assembly comprises at least two filter membranes which are arranged by successive and upward-and-downward lamination; the pore diameter of each filter pore of the upper filter membrane is larger than the pore diameter of each filter pore of the lower filter membrane; and the pore diameter of each filter pore of the lower filter membrane is 0.45 [mu]m. The filter membrane assembly provided by the invention solves the problem that the content of a suspended solid in water can not be accurately detected by a filter membrane in the prior art.

Description

technical field [0001] The invention relates to the field of suspended matter detection, in particular to a filter membrane module and a filter device having the same. Background technique [0002] Suspended matter refers to solid matter suspended in water, including inorganic matter, organic matter, mud sand, clay, microorganisms, etc. that are insoluble in water. The content of suspended matter 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. [0003] 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 solids in water quality refer to the substances that the water sample passes through the filter membrane with a ...
