Abstract

The invention discloses a device for detecting suspended matters in water, which is characterized by comprising a heating cavity, a drying mechanism, a weighing mechanism, a filter membrane for filtering and a base frame, wherein the heating cavity is fixedly connected to the base frame, the drying mechanism and the weighing mechanism are both arranged in the heating cavity, the interior of the heating cavity is at a constant temperature, the filter membrane is dried at the drying mechanism, and weighing is carried out at the weighing mechanism. The filter membrane is a borosilicate glass fiber filter membrane. The constant temperature of the heating cavity ranges from 105 DEG C to 107 DEG C, the cavity body of the heating cavity is made of high-temperature-resistant composite materials such as aluminum trioxide, polytetrachloroethylene and stainless steel plates, in the heating state, the temperature of the whole inner cavity can be kept at 105 DEG C all the time, and interference on a weighing system is avoided. The invention also provides a method for detecting suspended matters in water.

Description

technical field [0001] The invention belongs to the technical field of detection of impurity content in industrial circulating water and environmental water quality, and in particular relates to a device and method for fully automatic detection of suspended matter content in water quality. Background technique [0002] Suspended matter in water quality refers to the solid matter that the water sample passes through the filter membrane with a pore size of 0.45 μm, is retained on the filter membrane, and is dried at 103-105°C to constant weight. Excessive suspended solids in the water quality of the surface environment will easily make the water turbid, reduce the transparency, affect the respiration and metabolism of aquatic organisms, and even cause fish to suffocate and die, and even cause river channel blockage if there is more. Industrial circulating cooling water and boiler water contain a lot of suspended solids, which can easily cause the inner diameter of the water de...
