Document Type and Number:
WIPO Patent Application WO/2023/178966
Kind Code:
A1
Abstract:
Provided in the present invention is a modular multi-stage biochemical-filtering sewage treatment system, comprising at least one sewage treatment area, wherein each sewage treatment area comprises a first biochemical area, a first filtering area, a second biochemical area and a second filtering area which are sequentially in communication; one side of the first biochemical area is connected to a water inlet; a tail end of the second filtering area is connected to a clean water area; the tail end of the clean water area is provided with a water outlet; and the bottoms of the first biochemical area and the second biochemical area are provided with an aeration device. The sewage treatment system can integrate biochemical sewage treatment and mud-water separation; the first biochemical area is an anoxic area, and the second biochemical area is an aerobic zone, such that a multi-stage biochemical-filtrating treatment can be achieved; and in practical application, the number of sewage treatment areas can be adjusted according to the characteristics of sewage in an area to be subjected to treatment, thereby improving the practicability of the treatment system. By the above means, a biochemical sewage treatment and mud-water separation can be integrated without providing a sedimentation tank, thereby effectively reducing the cost of a sewage treatment process.
