Energy-saving film module for treating municipal wastewater

Abstract

The invention discloses an energy-saving film module for treating municipal wastewater. The energy-saving film module comprises a film box with an accommodating space and a plurality of treatment units arranged in the film box, wherein each treatment unit comprises an aeration pipe group, a water producing pipe group and a plurality of film assemblies, the aeration pipe group and the water producing pipe group are arranged in the film box, the film assemblies are fixedly arranged on the water producing pipe group, each film assembly is a curtain type film assembly and comprises two rows of curtain-shaped hollow fiber film figments and fixed components, the curtain-shaped hollow fiber film figments are vertically distributed, and the fixed components are used for fixing the hollow fiber film figments; and each aeration pipe group comprises an aeration pipeline and a plurality of aeration holes communicated with the aeration pipeline, and the aeration holes are formed at the lower part of the space between two rows of the hollow fiber film figments. The energy-saving film module has the advantages that the joggling force of the film figments is increased, the pollution resistance isrelatively good, the occupation area is small and advanced, and compared with the prior art, more energy is saved; and the energy-saving film module is suitable for the treatment fields of municipal wastewater and other wastewater.

Description

technical field [0001] The invention relates to an energy-saving membrane module used for municipal wastewater treatment. Background technique [0002] With the acceleration of urbanization and industrialization, the amount of municipal wastewater is increasing, the pollution is becoming more and more serious, and the treatment is becoming more and more difficult. Municipal wastewater mainly comes from domestic sewage, industrial wastewater and rainwater, which has the characteristics of very complex components, high organic matter content, high concentration of sewage, and difficult treatment. How to effectively treat municipal wastewater has become an important factor for urban development and sustainable social and economic development. Membrane separation technology is increasingly widely used in the field of municipal wastewater treatment due to its excellent performance. However, due to the complex composition of municipal wastewater and the characteristics of high or...

Problems solved by technology

Due to the limitation of the structure of traditional membrane modules, only one layer of traditional membrane modules can be placed in the wastewater treatment tank. The wastewater treatment tank occupies a large area and the cost of wastewater treatment is relatively high.
