SEWAGE DISPOSAL SYSTEM USING LONG FIBER FILTER OF MULTISTAGE AND METHOD FOR TREATING THEREOF

摘要

The present invention relates to a sewage treatment system using a multistage long-fiber filter and a treatment method thereof. The sewage treatment system of the present invention treats sewage directly by filtration using at least one pressurized long-fiber filter and at least one sub-absorbent long-fiber filter. The pressurized long-fiber filter directly filters the sewage, and the sub-absorbent long-fiber filter processes the backwash water of the filtered sewage to concentrate and dehydrate. Each of the pressurized long fiber filters and the submerged long fiber filters is provided in the form of a module having a plurality of mutually symmetric structures. According to the present invention, the sewage is directly subjected to filtration treatment using a pressurized long-fiber filter and an immersed long-fiber filter to reduce greenhouse gas without being influenced greatly by flow rate change, concentration and temperature change of the inflow sewage without microorganism treatment Effect can be obtained.
