Film biological treatment device for reuse of reclaimed water

Abstract

The invention discloses a film biological treatment device for reuse of reclaimed water, which comprises a device body, wherein the inside of the device body is provided with a film biological treater and a filtering chamber; the bottom of the film biological treater is provided with an aeration pipe network, and the upper part is provided with a film biological treatment chamber; the aeration pipe network is communicated with the film biological treatment chamber; the film biological treatment chamber is fully filled with suspended matters; a fibrous film is arranged above the film biological treatment chamber; the space above the fibrous film is communicated with the filtering chamber through a water pipe; a fibrous filtering body is arranged in the filtering chamber; a clear water cavity is arranged below the fibrous filtering body; a reuse water outlet pipe is arranged at one side of the clear water cavity; and the suspended matters are composed of porous shells and fillers. The film biological treatment device is simple in structure, provides a favorable growing carrier for microorganisms in the biological treatment chamber and has favorable filtering effect; and the arranged filtering chamber ensures that the effluent water has favorable water quality, the suspended substance content and turbidity of the effluent water approximate zero and the effluent water can be directly reused.

Description

technical field [0001] The invention relates to a reclaimed water reuse membrane biological treatment device, which belongs to the technical field of environmental protection sewage treatment. Background technique [0002] Due to the increasing scarcity of water resources in today's world, more and more attention has been paid to the recycling of wastewater. Most of the existing technologies use membrane biological wastewater treatment and reuse treatment equipment. popularity. At present, the traditional A / O biochemical method is generally used for sewage treatment. In order to effectively implement the national energy conservation and emission reduction environmental protection policy and make full use of water resources, the current advanced MBR membrane method at home and abroad is used for treatment, and the reclaimed water can be recycled in one step. use. The MBR method is an advanced sewage treatment technology at home and abroad. This technology has the character...
