Summary of the invention
The present invention is directed to the deficiency that existing membrane Bio-reactor Technology exists, the nesting type multidimensional membrane assembly dynamic membrane bioreactor that provide big, the difficult obstruction of a kind of unit membrane area, can further improve detergent power, effluent quality is good.
Nesting type multidimensional membrane assembly dynamic membrane bioreactor of the present invention adopts following technical proposals:
Nesting type multidimensional membrane assembly dynamic membrane bioreactor, comprise a body, aerated conduit and multidimensional membrane module, be divided into aeration zone and dynamic film bio reaction zone in the bed body, aeration zone one side of bed body is provided with water-in, the bottom is provided with aerated conduit, be provided with mud discharging mouth and rising pipe in dynamic film bio reaction zone one side, be connected with the back flushing aeration tube on the rising pipe, at least be fixed with one group of multidimensional membrane module in the bed body, every group of multidimensional membrane module is made up of the two-layer at least framework of about suit, each layer framework increases from the inside to the outside successively, the periphery of every layer of framework all is enclosed with filter screen, and the aperture of each layer framework upper filter screen increases successively from the inside to the outside, and all is filled with filler in the slit between the adjacent two layers framework, be provided with conduit in the inner chamber of the inside framework, the conduit in every group of multidimensional membrane module all is connected with rising pipe on the body.
Filler is a hard filler, is a kind of in haydite, gac, charcoal, stone, sand and the concrete body at least.
The past more framework nexine of the volume of filler particles is more little, so that form three-dimensional structure between each layer filler.
Framework is any solid geometry shape.
Multidimensional membrane module among the present invention constitutes with nested form, and the filter screen aperture of each layer framework increases from inside to outside successively, and pollutent is removed in layering.During operation, the water-in of sewage on the bed body flows into, and under aeration condition, microorganism breeds in a large number, thereby forms the large number of biological film on membrane module, improves processing efficiency.When sewage when having overworked biomembranous multidimensional membrane module, the particulate matter of larger aperture is directly stopped at outer space framework, and fine particle and soluble substance nexine by space framework on the dynamic membrane filtering of small-bore, sewage after being purified arrives innermost space framework inner chamber, flows out via the water outlet that is connected to intraluminal catheter in the inside space framework then.Excess sludge is then discharged by mud discharging mouth.
Multidimensional membrane module of the present invention is difficult for stopping up, back flushing easily, and the processing efficiency height, effluent quality is good, but direct reuse has been realized sewage recycling, can handle various wastewater, and is stable, life cycle is long, and is simple in structure, and operation, operation conveniently are easy to realize automatic control.
