Problems solved by technology

At present, pretreatment is mainly carried out through the filter screen. However, if the mesh is set too large, it may not be able to filter out large particles such as sludge and aquatic plants, which will still affect the use and analysis of the instrument, and may also block the pipeline; If the mesh is set too small, the flow rate of the water sample will be reduced, resulting in a serious hysteresis between the water sample analyzed by the instrument (that is, the pretreated water sample) and the water sample collected by the sampling pump, resulting in the timeliness of water sample analysis. poor

Embodiment Construction

[0029] In order to enable those skilled in the art to better understand the solution of the present invention, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings and implementation manners.

[0030] The pollution and harm of industrial wastewater discharge to the ecological environment have been recognized by the world. For this reason, all countries are enacting regulations on sewage discharge standards and punishment regulations to supervise and manage them, and the environmental monitoring technology that is the basis of supervision and management is also constantly developing and improving. , Water quality online monitoring technology is an environmental monitoring technology that has developed rapidly this year. It can conduct real-time and continuous automatic monitoring of wastewater discharged from industrial pollution sources, which is of great significance for improving the total amount of po...

Abstract

The invention provides a water-quality monitoring pre-treatment device. The water-quality monitoring pre-treatment device comprises a Y-type filter, a water inlet ball valve, a water outlet ball valve and a filter screen, wherein a water inlet of the Y type filter is connected with a sampling pump by a water inlet tube, so that primary filtration treatment is carried out on an original water sample collected by the sampling pump; a first outlet of the Y type filter is connected with the water inlet of a sampling cup by a water sample conveying pipeline; the filter screen is arranged at the water inlet of the sampling cup; the filter screen is used for carrying out secondary filtration treatment on the primarily filtered water sample conveyed by the water sample conveying pipeline; a second outlet of the Y type filter is used for discharging the primarily-filtered substances through the water outlet tube; the water inlet ball valve is arranged in the water inlet tube; the water outlet ball valve is arranged in the water outlet tube; water sample flow rate in the water sample conveying pipeline is controlled by regulating opening degree of the water inlet ball valve and / or the water outlet ball valve. Besides, the invention further provides a water quality monitoring system which is used for improving representativeness of a water sample and accuracy of the monitored result.

Description

technical field [0001] The invention relates to the technical field of water quality monitoring, in particular to a water quality monitoring pretreatment device and a water quality monitoring system. Background technique [0002] Water quality monitoring is the process of monitoring and measuring the types of pollutants in the water body, the concentration and change trend of various pollutants, and evaluating the water quality status. [0003] In order to improve the representativeness of the water sample and eliminate the factors that interfere with the analysis of the instrument and affect the use of the instrument, after the water sample is collected by the sampling pump, the water sample must be pretreated. At present, pretreatment is mainly carried out through the filter screen. However, if the mesh is set too large, it may not be able to filter out large particles such as sludge and aquatic plants, which will still affect the use and analysis of the instrument, and ma...
