The invention provides an external pressure type hollow fiber membrane system for sustainable aeration of a water supply system, which is characterized by comprising a water tank, at least one external pressure type hollow fiber membrane component, an aeration device, a water production pipeline and a washing pipeline, wherein each external pressure type hollow fiber membrane component is placed in the water tank; a membrane fiber bundle of external pressure type hollow fiber membranes on each external pressure type hollow fiber membrane component is horizontally and crossly immersed into the water body of the water tank; an air outlet of the aeration device is located below the external pressure type hollow fiber membranes; the water production pipeline is connected with a pipe connector on each water collecting device through a water production valve; and the washing pipeline is connected with the pipe connector on each water collecting device through a washing valve. The external pressure type hollow fiber membrane system provided by the invention is used for the water supply system and has the advantages of occupied area and resource saving, high efficiency, stable water output effect and long service life.
Description
technical field [0001] The invention belongs to purification equipment in the field of water supply treatment, and in particular relates to an external pressure hollow fiber membrane system for sustainable aeration of water supply systems, especially suitable for environments with large changes in indicators such as suspended solids, turbidity, microorganisms, and petroleum. Surface water is used as influent drinking water in the water production process. Background technique [0002] Due to environmental pollution and water shortage in today's world, the rapid development of water treatment technology is forced. Due to the many advantages of hollow fiber membrane technology (including larger filtration area, easier reverse cleaning and lower cost, etc.), it is widely used in water supply treatment, sewage treatment and reclaimed water reuse. [0003] The structure of the hollow fiber membrane in the hollow fiber membrane technology is a hollow tube. The length of the hollo...
