Abstract
The invention discloses a pure water test method of ozone water quality treatment. The invention adopts the following steps. The first step is to determine the pH value and IC value of source water. The second step is to adjust the pH value and the IC value of pure water to be the same as source water. The third step is to fill in ozone for pretreatment. Air aeration is injected to eliminate residual ozone after the pretreatment. The fourth step is to fill in ozone again until the ozone is saturated. The ozone concentration in pure water which is the solubility of ozone in pure water is detected. The beneficial effects of the invention are that the pH value and the IC content in water can affect the ozone self-decomposition and strong oxidation greatly. The pH value and IC value of pure water is adjusted to be the same as source water before the ozone treatment. And the ozone pretreatment is adopted. The effects of ozone consumption materials on the detection results are eliminated. The accuracy of the experimental dada is high. The experimental data is beneficial to the accuracy improvement of ozone dosage when used in ozone dosage calculation.
Description
(1) technical field
The present invention relates to a kind of pure water test method of ozone water treatment, be used for measuring the pure water ozone solution degree that calculates the ozone dosage.
(2) background technology
With the contaminated water source of ozone Oxidation Treatment water is a kind of method of water treatment preferably, when making oxidation processes, need calculated in advance to go out the ozone dosage, can quantitatively inject ozone like this, can reach the effect that neither waste can be cleaned out the objectionable impurities in the contaminated water source water again, contaminated water source water-ozone dosage can be determined by the pure water experiment, pure water ozone solution degree is an important parameter that calculates the ozone dosage, present test method is simple, be directly in pure water, feed ozone reach saturated the measurement, the data that this measuring method draws can influence the accuracy of calculating the ozone dosage.
(3) summary of the invention
The technical problem to be solved in the present invention is: a kind of pure water test method of ozone water treatment is provided, makes the accuracy height of its pure water ozone solution degree that records, help improving the accuracy of ozone dosage.
In order to solve the problems of the technologies described above, the present invention adopts following steps:
A measures source water pH and IC value;
B adjusts pure water pH and the IC value is extremely same with the source water;
C charges into the ozone pre-service, injects air aeration after the pre-service and removes residual ozone;
D charges into ozone once more to saturated, measures ozone concentration in the pure water, and this concentration is the solubleness of ozone in pure water.
For pH and the IC value that can accurately adjust pure water, when source water pH value is used H greater than 8 the time
3BO
3Adjust pure water pH value with the KCl mixed solution, when source water pH value is used NaH less than 8 the time
2PO4 and Na
2The mixed solution of HPO4 is adjusted pure water pH value; Adjust pure water IC with sal tartari.
In order to improve the clearance to ozone-depleting material in the pure water, injecting concentration of ozone gas among the described step c is 3.5g/m
3, gas flow rate: 1.0L/min, injection length 1h.
The invention has the beneficial effects as follows, because pH value and IC content in the water have considerable influence to ozone selfdecomposition effect and strong oxidation thereof, pH and the IC value of adjusting pure water before ozone treatment reach the source water state, and adopt the ozone pre-service, eliminated in the pure water ozone-depleting material to measuring the influence of fruit, the accuracy height of test figure when being used to calculate source water-ozone dosage, helps improving the accuracy of ozone dosage.
(4) embodiment
This specific embodiment comprises following test procedure:
The pH value and the IC (inorganic carbon) of a, mensuration source water, IC=TC-TOC.
B, usefulness pure water are poured the reactive tank wash clean into reactive tank to the pure water of the regulation water yield (11.5L).Because pH value in the water and IC content have considerable influence to the performance of ozone selfdecomposition effect and strong oxidation thereof, so need are with the pH value of damping fluid adjustment pure water, when source water pH value is used H greater than 8 the time
3BO
3Adjust pure water pH value with the KCl mixed solution, when source water pH value is used NaH less than 8 the time
2PO4 and Na
2The mixed solution of HPO4 is adjusted pure water pH value; Adjust pure IC with sal tartari; Make pure water pH and IC source water together.
C, the T-valve of ozone generator is switched to waste discharge ozone side, open ozone generator, regulate the generation knob, after ozone concentration on the concentration detector is stable.
D, small amount of matter consumes the influence of ozone to measurement result in the pure water, carries out the ozone pre-service earlier
Adjust ozone injection rate (concentration of ozone gas=3.5g/m
3, gas flow rate: 1.0L/min), T-valve is switched to reactive tank one end, injects ozone, water sample in the reactive tank is carried out pre-service about 1h, inject air aeration then, residual ozone in the water is removed.
E, charge into ozone to saturated once more, measure the concentration of ozone in the pure water, this concentration is the solubleness of ozone in pure water.
