Description

Technical Field

[0001] This application belongs to the technical field of sewage treatment, and specifically relates to a fixed membrane filtration device for an integrated sewage treatment equipment and a sewage purification method. Background Art

[0002] A fixed membrane filtration device is a device that uses membrane technology to filter sewage. The core lies in the setting of the fixed membrane. The fixed membrane generally includes ultrafiltration membranes, nanofiltration membranes, reverse osmosis membranes, etc. According to the different sizes of the membrane pores, they can effectively intercept suspended solids, bacteria, viruses and other pollutants in the sewage. The fixed membrane realizes the in-depth treatment and purification of sewage through the combination of its physical properties and chemical properties. The main advantages of the fixed membrane filtration device are its high treatment capacity. Compared with traditional sewage treatment methods, fixed membrane filtration can treat a large amount of sewage in a shorter time, while removing smaller particulate matter and dissolved substances. This high efficiency is because the membrane material has a very high filtration accuracy, which can achieve refined treatment of sewage at the microscopic level; membrane filtration technology can achieve effective separation under lower operating pressures, reducing the energy requirements for traditional treatment methods; the design of the fixed membrane filtration device usually considers the convenience of operation and maintenance; the fixed membrane filtration device has a wide range of applicability, and can be used not only for urban sewage treatment, but also for industrial wastewater treatment, domestic sewage treatment and other fields, and can select membrane materials with different pore sizes according to actual needs to meet the requirements of different sewage treatments; due to the high-precision filtration of the membrane, the treated water body contains almost no solid particles and most pollutants, and its water quality can reach or exceed national or local discharge standards, which is of great significance for protecting the water environment and promoting the reuse of water resources.
