Figure 3 is a view showing the configuration of a mobile water treatment apparatus according to an embodiment of the present invention, Figure 4 is a view showing the operation of the precipitation unit according to an embodiment of the present invention.

Referring to Figures 3 and 4 attached to the operation of the mobile water treatment apparatus 1 according to an embodiment of the present invention having such a configuration as follows.

First, as shown in FIG. 3, raw water used in a construction site is introduced and stored for a predetermined time, and then flows into the first pH concentration control unit 31.

At this time, sulfuric acid is introduced into the first pH concentration control unit 31, the raw water and sulfuric acid is first stirred by the stirring unit 31b, and the pH concentration of the raw water is first adjusted, and the raw water into which the sulfuric acid is introduced is the flocculant supply unit 32. Flows into).

Coagulants such as caustic soda and lactic acid alumina are supplied to the coagulant supply unit, and the raw water passing through the coagulant supply unit 32 is introduced into the second pH concentration control unit 33, and the polymer is supplied to the raw water.

As such, the raw water supplied with the coagulant for coagulating the drug and the foreign substances for pH adjustment is introduced into the precipitation unit 50, and the sludge in which the foreign substances are aggregated is stored on the inner bottom surface of the precipitation tank 51 while being stored for a predetermined time.

Then, when the shaft 52 is rotated by the rotation force providing means 53, the scraper 54 is rotated together to transfer the sludge deposited on the inner bottom of the settling tank 51 to the sludge discharge port 51b.

At this time, when the scraper 54 is rotated along the bottom of the sedimentation tank 51 in the state in close contact with the inner bottom of the sedimentation tank 51 when the rotary bar 54a rotates in the vertical direction, the sedimentation tank 51 The state in close contact with the bottom surface of the sedimentation tank 51 is transferred to the sludge discharge port 51b.

And, the sludge of the raw water introduced into the sedimentation tank 51 is settled in the sludge upper water is settled through the open upper portion of the sedimentation tank 51 when overflowed by the raw water flowing into the sedimentation tank 51 The tank 51 flows into the purified water storage tank formed outside, and is filtered by activated carbon contained in the purified water purification tank 80 to be used as industrial water or discharged to a river when the water is above a predetermined level.

On the other hand, the sludge introduced into the sludge storage unit 60 is introduced into the dewatering device 70 is separated into purified water and solids by the dewatering device 70, the separated purified water is recovered to the raw water storage unit 20 or a predetermined water supply If abnormal, discharge to the outside, the solids are discharged to a separate solid treatment space.

Figure 5 is a cross-sectional view of the settling portion according to another embodiment of the present invention.

5 is the same as the embodiment of FIGS. 1 and 4, but the load applied to the scraper 54 can be reduced when the scraper 54 transports the sludge deposited on the inner bottom of the sedimentation tank 51. It is formed into a structure.

As shown in Fig. 5, in this embodiment, unlike the previous embodiment, any one of the pairs of scrapers 54 has an uneven portion 54ba formed at the lower end of the scraper plate 54b.

As described above, the reason why the uneven portion 54ba is formed at the lower end of the scraper plate 54b of any one of the pair of scrapers 54 is that sludge is formed on the inner bottom of the settling tank 51 for a predetermined time. When the scraper 54 intends to transfer the sludge in a state where the precipitate is abnormally formed and the adhesion between the bottom and the sludge of the settling tank 51 is increased, the load applied to the scraper 54 is increased by the adhesive force, and thus the scraper 54 In order to prevent the life of the rotational force providing means 53 from being significantly shortened as the load increases to the rotational force providing means 53 for providing the rotational force, the scraper 54 having the uneven portion 54ba is rotated. Even if the sludge deposited on the bottom of the sedimentation tank 51 is scraped so that the adhesion between the sedimentation tank 51 and the sludge is lowered, the other scraper 54 may transfer the sludge with the lowered adhesion. As a result, the load applied to the scraper 54 according to the adhesive force between the bottom surface and the sludge of the precipitation tank 51 may be reduced, and accordingly, the load applied to the rotational force providing means 53 is also reduced, thereby providing the rotational force providing means 53. ), Which can significantly improve the service life.

Since the rest of the structure is the same as the above-described basic embodiment, the rest of the description will be omitted.

Although the present invention has been described in connection with the above-mentioned preferred embodiments, it is possible to make various modifications and variations without departing from the spirit and scope of the invention. Accordingly, the appended claims are intended to cover such modifications or changes as fall within the scope of the invention.
