Document Type and Number:
WIPO Patent Application WO/2017/200221
Kind Code:
A1
Abstract:
The present invention relates to a sewage treatment system using a multistage long-fiber filtering device, and a treatment method thereof. The sewage treatment system of the present invention uses at least one pressurized long-fiber filtering device and at least one submerged-type long-fiber filtering device to treat sewage by a direct filtration method. The pressurized long-fiber filtering device treats sewage by direct filtration, and the submerged-type long-fiber filtering device treats the sewage so as to dehydrate and dispose of the sewage by concentrating backwashing water from filtered sewage. Pressurized long-fiber filtering devices and submerged-type long-fiber filtering devices are respectively provided in modular form having a structure in which a plurality are symmetrical to each other. According to the present invention, because sewage is treated by direct filtration by using a pressurized long-fiber filtering device and a submerged-type long-fiber filtering device, the effect can be attained in which greenhouse gases are reduced without microbial treatment, while not being greatly influenced by a flow rate change, and concentration and temperature variations of inflowing sewage.
