Technical Field

Wherein, the inclined plate sedimentation tank is widely used because of the advantages of small occupied area, high treatment efficiency, simple and convenient operation and maintenance, etc. The existing inclined plate type sedimentation device generally comprises a sedimentation tank, wherein a plurality of inclined plates which are arranged in parallel are arranged in the sedimentation tank. These inclined plates are typically arranged at an angle such that when water passes through, suspended particles settle under gravity to the surface of the inclined plate and slide down the inclined plate to the bottom of the sedimentation tank. The design can increase the sedimentation area, thereby improving the solid-liquid separation efficiency.
However, the inclined plate type sedimentation device in the prior design has the following problems:
The floor space is large, and although the inclined plate design improves the sedimentation efficiency, the equipment per se still needs to occupy a large space for treating large-flow water, which is a remarkable limit in an environment with limited space.
The inclined plates are easy to block, and larger suspended particles or impurities easily block the gap of the inclined plates due to smaller interval between the inclined plates, so that water flow is not smooth, and the integral sedimentation effect and the treatment efficiency are affected.
The maintenance is difficult, the internal structure of the inclined plate sedimentation device is complex, the number of the inclined plates is large, the arrangement is dense, and the cleaning and maintenance work difficulty is high. Especially in the long-term operation process, sludge, bacteria and algae are easy to adhere to the surface of the inclined plate, so that the operation of equipment is influenced, and the water quality of effluent is reduced.
The sedimentation efficiency is limited, and the existing inclined plate type sedimentation device is difficult to realize efficient separation and sedimentation for tiny particles due to the limitation of sedimentation time and space, so that the final treatment effect is affected.
The operation energy consumption is high, and in order to maintain the smoothness of the water flow passing through the inclined plate, the existing device is often required to be provided with an additional water pump or other auxiliary equipment, which increases the overall energy consumption and the operation cost.
Accordingly, the prior art is still in need of improvement and development.
