Embodiment Construction

[0007] figure 1 As shown, it involves a high-level micro-power MBR device, including a sump 2, and a sewage lift pump 1 located at the bottom of the sump 2, the output of the sewage lift pump 1 is connected to the anoxic pool through a sewage pipeline 10 4 and evenly distribute water through the perforated pipe 9 horizontally arranged at the bottom of the anoxic pool 4; Membrane module 6, the upper part of the MBR flat membrane module 6 is connected to the external membrane outlet electric valve 3 through the membrane module outlet pipe 5, and the lower part is extended to the anoxic pool 4 through the nitrifying liquid return device 8 bottom.

[0008] The working process is as follows: in this equipment, the sewage is lifted to the anoxic pool 4 through the sewage lifting pump 1 arranged in the sump 2, and after the bottom of the anoxic pool 4 is evenly distributed through the perforated pipe 9, the waste water of the sewage lifting pump 1 is continued to be used. The press...

Abstract

The invention discloses an elevation-type micro-power MBR apparatus including a water collection tank and a sewage lifting pump arranged on the bottom thereof. An output end of the sewage lifting pump is connected into an anoxic tank through a sewage pipeline and is used for distributing water uniformly through a hole pipe vertically disposed on the bottom of the anoxic tank. The upper part of the anoxic tank is communicated with an MBR membrane tank. An MBR plate membrane assembly is arranged in the MBR membrane tank. The upper part of the MBR plate membrane assembly is connected to a membrane water outlet electronic valve, which is arranged externally, through an arranged membrane assembly water outlet pipe. The lower part of the MBR plate membrane assembly is stretched to the bottom of the anoxic tank through an arranged nitration liquid backflow apparatus. The apparatus is high in automation degree and achieves unattended operation. The apparatus is greatly reduced in operation energy consumption and is almost operated under micro power, so that investment on equipment is reduced and a nitration liquid backflow pump and a sucking pump are avoided. The apparatus can be assembled according to different water load and irregular landforms, so that damage on surrounding environment due to installation of equipment is reduced as more as possible.

Description

technical field [0001] The invention relates to a high-range micro-power MBR device. Background technique [0002] At present, the MBR membrane biological treatment process is one of the processes with the most advanced technology and the best treatment effect in the field of sewage treatment, and its effluent water quality standard is better than the various indicators required by national laws. This process organically combines biodegradation and membrane separation technology. Due to the high-efficiency retention of the membrane, microorganisms are trapped in the membrane bioreactor, which greatly improves the accumulation density of dominant microorganisms in each treatment structure, thus ensuring sufficient Degradation of various pollutants by microorganisms. At present, for small-scale domestic sewage, the sewage is lifted to the anoxic tank through the lifting pump and then flows into the MBR membrane tank by itself, and finally the suction pump is used to suck out ...
