Problems solved by technology

If all users are forcibly divided into a limited number of types, and only a few types of products are manufactured, it will seriously damage the performance of the product, reduce the quality of service, and make users unacceptable.
The production process of the second type of goods is relatively complicated, the work efficiency is relatively low, and the production cost is relatively high, but in order to ensure the service quality of the product, it is worth paying these prices
In other words, there are two water samples with the same concentration of suspended particles, but the size, shape, surface characteristics, chemical composition, specific gravity and color of their suspended particles are very different. So, will they cause harm to human health? different impact? We have not found relevant technical literature so far, so we will not discuss it for the time being

Embodiment Construction

[0050] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0051] Such as Figure 1-2 As shown, first clean the system device with pure water and air dry. And put several layers of standard filter paper weighed in units of μg in the aerosol sample collector 6 in advance, wherein the water volume regulating valve 4 should be closed. Specific water samples can be taken from the following water bodies: lakes, rivers, open channels, well water, spring water, mine water, sedimentation tanks, quick filter tanks, clean water tanks, and various pressure water supply pipes and artesian drainage pipes. Wherever a water sample is taken, it is used to calibrate the turbidimeter that will be used there.

[0052] Divide the specific water sample taken into two parts, A and B. Immediately seal the water sample A with a non-absorbent cover to prevent its water from evaporating and prevent outside wi...

Abstract

The invention discloses a user-based demarcating method and a sample collecting system of a water nephelometer, effectively solving the technical difficulty that the prior water turbidness numerical value deviates from the water aerosol concentration numerical value. The user-based demarcating method is characterized in that a specific water sample in a water body from a preset user of a nephelometer is taken as standard liquid for demarcating the nephelometer; the collected specific water sample is divided into an A part and a B part, and because the aerosol concentration of the water sampleA and the water sample B is equal, when the aerosol concentration of the water sample B is detected by the sample collecting system and a collecting device, the water sample A becomes the standard liquid with known aerosol concentration. The water sample A is put in the electronic nephelometer to be demarcated, and the ratio of the scattered light intensity and incident light intensity or the transmitted light intensity and the incident light intensity of the electronic nephelometer is measured, is converted into digital numbers equivalent to the aerosol concentration of the water sample A, and is conveniently and accurately displayed on a display screen of the nephelometer.

Description

1. Technical field [0001] The invention relates to a household calibration method and a sample collection system for urban water supply water quality turbidimeters. Specifically, the current turbidimeters use standard liquids configured with specific substances to calibrate the scale of the turbidimeter, while the present invention uses the water samples collected from the actual water body of each user to calibrate the scale of its own turbidimeter. , so that the reading of the turbidity meter is close to the value of the concentration of suspended particulates in the water body. The invention does not change the basic working principle and structure of the current turbidimeter. 2. Background technology [0002] In the technical books known to the society, the following relevant knowledge has been confirmed: [0003] Impurities in water are divided into four types according to their particle size: [0004] The first is molecular or ion state: its particle size is 1×10 -...
