Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of softening of reclaimed water, and particularly relates to a reclaimed water system hardening removal and softening treatment device. BACKGROUND

[0002] Reclaimed water treatment refers to the treatment of various drainage water to reach the water quality standard, which can be reused in a certain range. The reclaimed water treatment method is generally to adopt different treatment units according to the content of various pollutants in domestic sewage, the use of reclaimed water and the required water quality, to form a process flow that can meet the water treatment requirements. Some reagents are often added during the hardening removal and softening process, so as to convert the calcium and magnesium ions in the water into insoluble compounds, and make them precipitate, such as lime softening method.

[0003] In the existing softening and hardening removal process, water is injected into the water tank, and the work of adding lime in the same proportion is carried out at the same time. The lime milk is directly put into the water tank and then mixed by using the stirring mechanism, which can easily cause uneven softening. After part of the sewage in the water tank is softened, the sewage contacts the continuously added lime again, which causes the overuse of lime milk. Therefore, it is not convenient to add lime and mix at the same time before the water is added into the water tank, which increases the cost of raw materials and affects the softening treatment efficiency.

[0014] The above components achieve the effect that the sliding rail and the sliding sleeve can cooperate with the positioning bolt to adjust the position of the flow resistance plate, thereby adjusting the distance between the flow resistance plates, adjusting the overall movement stroke of the sewage, and increasing the sedimentation effect.

[0015] Preferably, the material guiding assembly comprises a material guiding bottom plate obliquely arranged at the bottom of the box body, and the material guiding bottom plate is fixed with two symmetrical material guiding side plates.

[0016] The above components achieve the effect that the material guiding bottom plate can cooperate with the material guiding side plates to guide the sediment blocked by the flow resistance plate to the drain pipe.
