[0002] At present, in the sewage purification operation, sludge sedimentation is an important process to realize the sewage purification operation. In the current sludge sedimentation operation, the sedimentation operation is mainly carried out through sedimentation tanks and other equipment. Although it can meet the needs of the sedimentation operation, the sewage The efficiency of sludge sedimentation operation is low, the structure of sedimentation tank equipment is large, and the maintenance and use costs are relatively high, which seriously affects the work efficiency and cost of sludge sedimentation and sewage purification operations. Folding plate multi-stage sedimentation tank for sewage treatment", this kind of traditional sedimentation equipment has defects such as low sedimentation efficiency, high material and energy consumption, high maintenance and operation costs to varying degrees, and based on the current traditional sedimentation equipment. The sludge also lacks effective reuse capacity, which causes serious waste of materials and is also very easy to cause secondary pollution due to sludge

Embodiment Construction
[0021] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.
[0022] Such as figure 1 The described continuous-flow alternating folding-plate high-efficiency sludge sedimentation process comprises the following steps:
[0023] S1, preliminary filtration, first the folded plate filter is positioned on the working surface, and the axis of the folded plate filter is distributed parallel to the horizontal plane, and then the sewage flowing through the sewage pipe is first raised by the booster pump to 3-5 times the standard Atmospheric pressure, rectify the sewage into a water column with a diameter of 5-50 cm, then filter the water column through a three-layer filter, rectify the purified water column, and pour it through the water inlet of the folded plate filter in a direction perpendicular to the horizontal ...

The invention relates to a continuous-flow alternating folding-plate high-efficiency sludge sedimentation process, which includes four steps of preliminary filtration, sedimentation operation, sludge collection and treatment, and sedimentation treatment. On the one hand, the present invention can effectively improve the working efficiency and quality of sludge filtration and sedimentation in sewage, and improve the efficiency of solid-liquid separation and purification; on the other hand, in the sludge sedimentation process, the sedimentation process and sedimentation equipment structure are effectively simplified , and the sedimentation process can be flexibly adjusted according to the actual work needs, and at the same time, it can effectively reduce the energy consumption of the sedimentation operation and the loss of auxiliary materials, and greatly improve the comprehensive recycling rate of materials, and reduce the secondary pollution caused by the sludge sedimentation and purification operation. At the same time as the occurrence of raw pollution, it greatly improves the comprehensive utilization of resources and achieves the effect of reducing the cost of sludge sedimentation operations.
