Physical precipitation membrane separation device

Abstract

The invention provides a physical precipitation membrane separation device, belongs to the technical field of surface water treatment devices, and solves the technical problems of high cost and/or secondary pollution of coagulating sedimentation filtration treatment in the prior art. The physical precipitation membrane separation device comprises a sedimentation tank (1), a water supply assembly and a hollow fiber membrane device mounted in the sedimentation tank (1); the sedimentation tank (1) is communicated with the water supply assembly, the water supply assembly can convey surface water into the sedimentation tank (1), surface water is conveyed from bottom to top, and at least a surface water and sediment separation area can be formed in the sedimentation tank (1); and the hollow fiber membrane device is at least arranged at a height position where the separation area is formed in the sedimentation tank (1), and is used for filtering the separated surface water. The function of the surface water treatment device is perfected, and the requirements of people for low cost and high efficiency of surface water treatment are met.

AI Technical Summary

Benefits of technology

This patented technology uses one step treatments instead of multiple stages of filtering processes like conventional ones. It eliminates the need for expensive reagent addition while ensuring better clarity during filter operations. Additionally, this design improves the overall performance of the system without generating harmful substance levels that can be found at home. Overall, these technical improvements make the new type of apparatus more efficient than existing systems but also less priced compared to current technologies.

Problems solved by technology

This patents describes different ways for filtering rainwater on an urban basis without causing environmental damage during its use. However, these techniques can also lead to increased energy consumption when they work overnight. Additionally, some existing systems involve multiple stages of processing involving various chemical substances like calcium hydroxypropyltriethoxysilane (CMPS), polyvinyl chloride polymerization resin(PVC) and polystyrene sulfonic acid (PSA). These technical solutions aimed towards reducing resource usage while maintaining good cleanliness levels within acceptable limits.
