specific Embodiment approach 1

[0006] Specific implementation mode one: the following combination figure 1 This embodiment will be specifically described. The method of the present embodiment is realized through the following steps: 1. Submerge the No. 1 online particle number detection device 10 in water and the No. 2 water particle number online detection device 11 in the flowing detected water, and immerse the No. 1 water particle number online detection device 10 In the flowing water body before adding the permanganate composite agent, the No. 2 water particle number online detection device 11 is immersed in the position where the added permanganate compound agent flows for one to five minutes; The number of particles in water on-line detection device 10 and the second number of particles in water on-line detection device 11 output standard voltage signals reflecting the number of particles in water per unit volume through No. 1 A / D conversion circuit 13 and No. 2 A / D conversion circuit 14 respectively....

specific Embodiment approach 2

[0007] Specific implementation mode two: the following combination figure 2 This embodiment will be specifically described. No. 1 on-line detection device 10 for the number of particles in water and No. 2 on-line detection device 11 for the number of particles in water of the present embodiment are respectively composed of an infrared light source 4, a transmitted light detector 5, an analog-to-digital converter 6, and an analog-to-digital converter 7 , microprocessor 8, digital-to-analog converter 9, power supply 4-1, voltage detection unit 4-2, No. 1 transparent window 1, No. 2 transparent window 2 and sensor housing 3, infrared light source 4, transmitted light detector 5. Power supply 4-1, voltage detection unit 4-2, one-way analog-to-digital converter 6, and two-way analog-to-digital converter 7 are set in the sensor housing 3, and the first transparent window 1 and the second transparent window 2 are embedded in the sensor The sensor housing 3 is sealed on the housing ...

specific Embodiment approach 3

[0010] Specific embodiment three: the difference between this embodiment and embodiment one is that: in step one, No. 2 water particle number online detection device 11 is immersed in the position where the added permanganate composite agent flows for three minutes At this position, the permanganate complex agent reacts completely with various reducing inorganic and organic substances in the water. At this moment, the particle number signal is stable and the detection lag time is short. Other steps are the same as those in Embodiment 1.

Abstract

An in-line test method for testing the pollutant-removing efficacy of the composite permanganate chemical includes such steps as immersing the in-line particle counter A in the flowing water at the position where said composite permanganate chemical is not applied for counting the particles in the water, immersing the in-line particle counter B in the water at the position where the water is flowing to for 1-5 min after said chemical is applied for counting the particles in the water, respectively converting their output voltages to digital values A and B, and calculating the pollutant-removing efficacy C by C=B/A in an arithmatic unit.

Description

Technical field: [0001] The invention belongs to a method for detecting the dosing effect of water treatment, and in particular relates to a method for on-line detecting the decontamination efficiency of a permanganate compound agent. Background technique: [0002] With the rapid development of my country's economy, the problem of environmental pollution has gradually become prominent. The pollution rate of drinking water sources in my country is as high as 90%. The current conventional water supply treatment process is difficult to effectively remove trace pollutants in water. Although the concentration of these trace pollutants is very low, they are very harmful to human health. The permanganate composite agent is made of potassium permanganate as the main agent, compounded with various auxiliary agents that can improve the decontamination efficiency of potassium permanganate, and processed by a special method. For example, the publication number is 1103628 invention paten...
