Analysis of Experimental results
And measuring each index according to the formulated performance evaluation scheme of the water purifying device to obtain corresponding measured data. The data obtained after the experiment were subjected to statistical processing and analysis, and performance analysis was performed. The evaluation index standard is according to sanitary Standard for Drinking Water (GB 5749-2006), and the five standards are shown in Table 1.
TABLE 1 Drinking Water quality Standard
(1) Total number of bacteria
As can be seen from Table 2, the total number of bacteria in the purified water is in the range of 16-30/mL, and the value is far lower than the limit value of the total number of bacteria in the drinking water standard of 100/mL, which indicates that the water purified by the water purifying device can effectively remove the bacteria in the water, so that a small amount of bacteria exist in the purified water.
As shown in fig. 4, when the filtered water volume is 0.5L, the total number of bacteria is 25/mL, which is at a relatively high level, and the reason for analyzing is that the water purifying effect is not at the best and most stable state because the water purifying device is in the initial filtering state and the water purifying system is in the cleaning state, so the value is at a relatively high level. In addition, when the purified water amount reaches 20L, the numerical value of bacteria has a trend of relatively less obvious increase, which indicates that a certain problem occurs in the sterilizing performance of the water purifying device, and the reason is presumed that the problem may occur due to the fact that the pressure applied to the water purifier is too high at 20L, and the tightness of the water purifier is so high that a small amount of natural bacteria in the air enter the water body, so that the total number of bacteria in the water body is increased.
TABLE 2 Total bacterial values determined for different amounts of purified water
| Water intake | Raw water | 0.5L | 1L | 2L | 5L | 10L | 20L | 30L |
| Total number of bacteria | / | 25 | 16 | 17 | 21 | 20 | 27 | 30 |
(2) Permanganate index (GMI)
According to the restriction of raw water source, the oxygen consumption of raw water is 6.62mg/L, and according to the sanitary Standard for Drinking Water (GB 5749-2006), the standard limit value of permanganate index is 5mg/L. The experimental data after treatment are shown in table 3. The obtained permanganate index data are all lower than 5mg/L, which shows that the water purifier has certain removal efficiency on organic matters in water, the removal rate is between 30% and 39%, but the removal effect is not obvious.
As shown in fig. 5, the permanganate index obtained after the measurement of the water samples taken at each point is within the range of 4 to 4.4, and the fluctuation of the value is not obvious, which indicates that the removal efficiency of the portable water purification device on organic matters is in a stable state within the water intake of 30L, and the performance of the portable water purification device on the aspect of removing organic pollutants is stable within a certain water purification amount range.
TABLE 3 permanganate index values and organic removal rates measured after different water purifications
(3) Total hardness of
As can be seen from Table 4, the total hardness of the drinking water is limited to 450mg/L, the total hardness of the raw water is 154.74mg/L, which is much less than the standard limit, and the original water quality is lower than the water quality requirement specified by the standard. Through calculation of the total hardness removal rate, the removal rate of the water purification device to hardness ions is only 29-33.5%, and the removal effect is not obvious.
As shown in fig. 6, the removal rate of the total hardness is generally in a more stable state. However, it can be seen from the figure that the removal rate of the total hardness begins to decrease significantly when the water intake amount reaches 20L. Presumably, in the purification process, the filter material such as filter cotton has a certain adsorption effect on the substances in the water solution, and as the water intake is increased continuously, and the frequency and the force of the hand pump pressure pump are increased in the later period, so that a stable and higher water pressure is generated in the pump, water flow can rapidly pass through the water purification material and has a certain scouring effect on the adsorption material, and adsorbed ions enter the water again, so that the total hardness value is increased, and the removal rate is reduced.
TABLE 4 Total hardness values and hardness ion removal rates measured for water samples taken at different net water volumes
(4) pH value of the solution
As can be seen from Table 5, the pH value of the water purified by the water purifier is between 6.5 and 8.5 within the range of 30L of water intake, and the water is in a standard state, and the fluctuation value is within 0.07 pH range, and the fluctuation value is relatively small. As shown in fig. 7, the ph of the purified water is maintained substantially constant as the amount of purified water increases, which indicates that the purified water obtained by the water purifier is stable.
TABLE 5 pH of purified Water measured by filtration of Water bodies of different volumes
| Water intake | Raw water | 0.5L | 1L | 2L | 5L | 10L | 20L | 30L |
| pH | 7.66 | 7.23 | 7.19 | 7.21 | 7.26 | 7.21 | 7.26 | 7.23 |
(5) Turbidity of the solution
TABLE 6 turbidity of water samples taken with different water purification amounts
As can be seen from Table 6, the turbidity of the raw water was 0.32NTU, which is lower than the standard limit. The water quantity measured at other points is lower than the turbidity value of the raw water and lower than the standard limit value. As shown in FIG. 8, after the portable water purifier is purified, the turbidity is obviously reduced, the value except the water amount data of 0.5L is around 0.14NTU, and the fluctuation is not more than 0.01NTU. The reason why the turbidity was 0.20NTU when the amount of water taken was 0.5L, which was slightly higher than that of the water taken at other stages, is presumably because the retention of the substances in the water body was not yet the best because the pore size of the filter was relatively large at the initial stage of the water purification apparatus.
On the basis of the performance test analysis of the water purifying device, the following conclusion is drawn:
(1) The main water quality indexes are measured, and the result shows that the water purifying device can generate a certain degree of removal effect on organic matters, and the removal rate can reach 30-39%; hardness ions in water can be removed to a certain degree, and the removal rate can reach 33 percent at most; the turbidity is reduced from 0.32NTU to about 0.14NTU, and the numerical value is obviously reduced, which shows that the portable water purifier can effectively remove most substances in the water which influence the turbidity; the number of bacterial colonies obtained by the determination result is between 16 and 30/mL, which is far less than the standard limit value, so that the removal effect on bacteria is obvious; the pH value of the purified water body is neutral as a whole.
(2) The portable water purifying device has the advantages that the index values are all lower than the drinking water standard limit value within the range of 30L of purified water; the numerical values of all indexes are on a stable level on the whole, which shows that the portable water purifying device has stable performance in the range, the purified water quality conforms to the water quality standard of drinking water, and can be directly drunk by human bodies, thereby ensuring the drinking safety of the human bodies.
