[0002] Before purifying water, water purification equipment needs to ensure that there are no impurities in the water to avoid damage to the water purification equipment. This is because natural water contains a large amount of impurities, such as silt, clay, organic matter, microorganisms, mechanical impurities, etc. The presence of these impurities seriously affects the water quality and treatment effect of refined water. Therefore, some impurities must be reduced or removed before fine treatment, which requires pretreatment, sometimes also called pretreatment.

[0003] There are many methods of pretreatment, mainly including: sedimentation, clarification, filtration, softening, disinfection. Sedimentation usually involves adding chemical agents into the sedimentation tank to cause the impurities to undergo a nucleation reaction, and the impurities are precipitated through the horizontal pipes installed inside the sedimentation tank. In order to achieve a better sedimentation effect, it is necessary to design a pre-sedimentation device for water purification equipment, which uses a low-flow rate natural sedimentation before the water enters the sedimentation tank, so that the impurities in the water are effectively reduced after entering the sedimentation tank, thereby making the water sedimentation effect better, thereby indirectly improving the quality of the treated water.

[0025] Embodiment 2:

[0026] Figure 1-5A pre-sedimentation device for a water purification device according to an embodiment of the utility model is shown, which includes a concrete pool 1: the concrete pool 1 includes a pre-sedimentation pool 101, a water storage tank 102 is built on the left side of the pre-sedimentation pool 101, a sedimentation tank 2 is arranged on the right side of the concrete pool 1, a water flow ladder 3 is built in the inner cavity of the pre-sedimentation pool 101, the water flow ladder 3 is higher on the left and lower on the right, a plurality of water outlet grooves 4 are opened on the right side of the top of the water storage tank 102, an inlet pipe 8 is connected between the concrete pool 1 and the sedimentation tank 2, a valve 9 is installed on the left side of the top of the inlet pipe 8, the bottom end of the valve 9 passes through the inner cavity of the inlet pipe 8, the right side of the top of the inlet pipe 8 is connected with an external pipe 10, the bottom of the front and rear right sides of the pre-sedimentation pool 101 are connected with a sewage pipe 7, a valve 2 11 is installed on the top of the sewage pipe 7, and the bottom end of the valve 2 11 passes through the inner cavity of the sewage pipe 7.

[0027] Working principle: When the utility model is used, the user continuously adds the water to be purified into the inner cavity of the water storage tank 102, and then the water in the inner cavity of the water storage tank 102 flows to the left side of the top of the water flow ladder 3 through multiple water outlet troughs 4, and then slowly flows to the right side of the inner cavity of the water storage tank 102 through multiple slopes 5 at the top of the water flow ladder 3. At this time, the water undergoes the first natural sedimentation. Due to the obstruction of the water retaining plate 6, the water stays in the inner cavity of the water storage tank 102 for a while, allowing the water to undergo the second sedimentation. After the water accumulates, it overflows the top of the water retaining plate 6 and enters the inner cavity of the sedimentation tank 2 through the water inlet pipe 8. Here, the user can The external pipe 10 adds chemical agents into the inner cavity of the water inlet pipe 8, so that the impurities in the water undergo a flocculation reaction in the inner cavity of the flocculation tower 22.

The above-mentioned sedimentation tank 2 and water purification equipment 12 are prior art means and will not be elaborated on here. If there is too much sediment in the concrete pool 1, valve one 9 can be closed and valve two 11 can be opened. The sediment can be discharged through the sewage pipe 7 by a scraper or water flushing, so that the impurities in the water can be effectively reduced after entering the sedimentation tank, and then the water sedimentation effect can be better, thereby indirectly improving the quality of the water after treatment.

[0028] In summary: the water purification equipment uses a pre-sedimentation device, through the coordinated use of the concrete pool 1, the water flow ladder 3 and the water outlet trough 4, so that the water flows slowly and at a low speed to the inner cavity of the sedimentation tank 2, thereby achieving a natural sedimentation effect. Through the setting of the sedimentation tank 2, the water is precipitated again, which can effectively reduce the impurities in the water after entering the sedimentation tank, and then make the water sedimentation effect better, thereby indirectly improving the quality of the water after treatment.
