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 according to the present invention treats sewage in a direct filtering scheme by using at least one pressurized long fiber filter and at least one submerged long fiber filter. The pressurized long fiber filter directly filters sewage, and the submerged long fiber filter concentrates, dehydrates, and discards backwash water of filtered sewage. Each of the pressurized long fiber filter and the submerged long fiber filter is provided in a module form having a plurality of mutually symmetrical structures. According to the present invention, sewage is directly filtered by using a pressurized long fiber filter and a submerged long fiber filter, and thus the effect of reducing a greenhouse gas without being affected by changes in the flow rate, concentration, and temperature of inflow sewage can be ensured without microbial treatment.
