Detailed Description

The utility model provides a detect sewage quality of water multi-parameter subassembly, including detection cabinet 12 and flowmeter 5, be equipped with chlorine residue sensor 2 in the detection cabinet 12, PH sensor 3, coulometer 4, RS48511 and circulation groove 8, be equipped with on the circulation groove 8 and extend to disinfection pond sampling tube 13 and the disinfection pond sample back flow 14 in the detection cabinet 12 outside, be equipped with disinfection pond sample pump 6 and disinfection pond sample back flow 7 on disinfection pond sampling tube 13 and the disinfection pond sample back flow 14 respectively, chlorine residue sensor 2 and PH sensor 3 are equipped with chlorine residue sensor sense terminal 9 and PH sensor sense terminal 10, chlorine residue sensor sense terminal 9 and PH sensor sense terminal 10 set up in circulation 8, flowmeter 5, electric energy meter 4, chlorine residue sensor 2 and PH sensor 3 are connected with RS 48511.

In this embodiment, the electric energy meter 4, the flow meter 5, the residual chlorine sensor 2, and the PH sensor 3 are connected in parallel.

In this embodiment, the disinfection pond sampling pump 6 takes a water sample out of the circulation tank 8 in the detection cabinet 12, and is used for detecting the residual chlorine sensor 2 and the PH sensor 3, and after the detection is finished, the disinfection pond sampling reflux pump 7 takes out the water in the circulation tank 8.

In this embodiment, the residual chlorine sensor detection end 9 and the PH sensor detection end 10 of the residual chlorine sensor 2 and the PH sensor 3 are disposed in the circulation tank 8, the residual chlorine sensor 2 is used for detecting residual chlorine in water, the PH sensor 3 is used for detecting hydrogen ion concentration in water, and the flow meter 5 is used for monitoring sewage flow.

In this embodiment, when the detection end 10 of the PH sensor 3 contacts the object to be detected, the glass electrode, the reference electrode and the object to be detected form a galvanic cell, so that the solution undergoes ion exchange movement. That is, the ion exchange reaction between the ions in the glass film and the hydrogen ions in the analyte forms a certain potential difference, and the larger the potential difference is, the higher the hydrogen ion concentration is. Therefore, the concentration of the hydrogen ions in the detected object can be known according to the formed potential difference, and the acid-base degree, namely the PH value of the detected object is known. The detection end 9 of the residual chlorine sensor 2 contains two measuring electrodes, an HOCL electrode and a temperature electrode. The HOCL electrode belongs to the clark type current sensor and is fabricated using microelectronics technologies for measuring the concentration of hypochlorous acid (HOCL) in water. This sensor consists of three electrodes of small electrochemical type, one Working Electrode (WE), one Counter Electrode (CE) and one Reference Electrode (RE). The method of measuring the concentration of hypochlorous acid (HOCl) in water is based on measuring the change in current generated by the working electrode due to the change in hypochlorous acid concentration.

In this example, RS48511 transmits the data detected by the residual chlorine sensor 2 and the PH sensor 3, the data monitored by the flow meter 5, and the data of the electric energy meter 4 to the PLC1 through 485MODBUS communication.
