Water quality analysis system

Abstract

The invention discloses a water quality analysis system. The water quality analysis system comprises a data collection unit and a data detection unit, wherein the data detection unit comprises a flow cell, a detection electrode and a sampling pipeline; one end of the detection electrode is arranged in the flow cell; one end of the sampling pipeline is connected with the flow cell; the other end of the detection electrode is electrically connected with the data collection unit, and is used for transmitting detection data to the data collection unit, and the data collection unit is used for sending the received detection data via a remote communication port; the flow cell comprises a cover body, a cell body and a separating plate, the cell body is matched with the cover body, the separating plate is arranged in the cell body, the cell body is of a double-layer hollow structure, a separating strip is arranged at the bottom part of an inner layer, one side of the separating plate is provided with a groove, and the groove is clamped with the separating strip; a circular hole is formed in the cover body, and the detection electrode penetrates through the circular hole; a circular hole is formed in the bottom part of the cell body, and the sampling pipeline penetrates through the circular hole. The water quality analysis system has the advantages that by adopting the manner, the detection data can be transmitted in real time, and the detection accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of water quality monitoring, in particular to a water quality analysis system. Background technique [0002] Water quality analysis is the process of evaluating water quality. Analysis items can be divided into two categories, one is items reflecting water quality conditions, such as: temperature, turbidity, dissolved oxygen detection, etc., and the other is toxic substance detection items, such as: Arsenic, lead, chromium, organic pesticide detection, etc. At present, the most widely used detection methods are chemical method and ion selective electrode method. The above two methods have the following disadvantages: the chemical method usually has low measurement accuracy and pollutes the environment, and it needs to be tested on-site or the sample is taken to the laboratory for testing, which is time-consuming and laborious; the ion-selective electrode method usually uses a flow cell for detection , but ...

Problems solved by technology

The above two methods have the following disadvantages: the chemical method usually has low measurement accuracy and pollutes the environment, and it needs to be tested on-site or the sample is taken to the laboratory for testing, which is time-consuming and laborious; the ion-selective electrode method usually uses a flow cell for detection , but the flow cell is directly in contact with the external environment, which affects the water quality detection effect, and the flow cell is usually equipped with a fixed partition to separate the electrodes. The existence of the partition affects the cleaning effect of the flow cell; chemical method, ion selective electrode The real-time transmission of detection data cannot be realized by this method, so that relevant personnel cannot grasp the situation of water quality in time and reduce the efficiency of water quality detection
