Abstract

The invention relates to a sewage filtering treatment device based on a gas detection function. The sewage filtering treatment device comprises a sewage filtering treatment device body and an SAW sensor which is installed in the sewage filtering treatment device and used for monitoring the concentration of CO2 and NO2. Based on an SAW device, the SAW sensor is provided with a five-channel structure, a third channel serves as a reference channel, a sensitive area of a first channel and a sensitive area of a second channel are coated with a first sensitive thin-film material for detecting CO2, a sensitive area of a fourth channel and a sensitive area of a fifth channel are coated with a second sensitive thin film material for detecting NO2. Each gas is detected through two channels, the stability of gas detection is greatly improved, credibility of reading data of the sensor is guaranteed, repeatability is good, and the testing stability is good at the high temperature. The sewage filtering treatment device can detect CO2 and NO2 in the working process in a high sensitivity and high reliability mode.

Description

technical field [0001] The present application relates to the field of sewage treatment, in particular to a sewage filtration treatment device based on gas detection function. Background technique [0002] With the continuous development of industry, more and more water bodies have been polluted recently, and they are increasingly threatening people's normal production and life. Sewage treatment equipment can effectively treat domestic sewage, industrial wastewater, etc., and prevent sewage and pollutants from flowing directly into waters. [0003] During the sewage treatment process, since the sewage often contains pollutants such as organic matter and microorganisms, a large amount of CO2, NO2 and other gases will be generated during the treatment process, which will affect the normal operation of the equipment in severe cases, and even affect the operation. personal safety of personnel. Contents of the invention [0004] In order to overcome the problems existing in t...
