The combined treatment device of aerobic baffling reaction unit and membrane treatment appts
Technical field the utility model relates to a kind of adaptation and is used for sewage treatment area, with the combined treatment device of aerobic baffling reaction unit and membrane treatment appts, especially can make the combined treatment device of reusing sewage.
The existing waste disposal plant of background technology comprise simply clearly wash in a pan, types such as anaerobic treatment, anaerobic-aerobic processing, physical chemistry processing, substantially can realize the cleaning or the harmless treatment of sewage, that but most of device all can not disposable realization is innoxious, the processing of the resource utilization target of conserve water resource simultaneously, causes the waste of secondary pollution and water resources easily.
Summary of the invention
For the pollution that solves existing sewage is handled problems, improve handling back water quality makes it can the reuse native system or greenery patches irrigation etc., the utility model provides a kind of combined treatment device, not only thoroughly solve sewage colourity, bacterium etc. and polluted enquirement, also be greatly improved aspect other contamination indexs of sewage disposal, making it reach the emission standard of middle water or surface water.
The technical scheme in the invention for solving the technical problem is: aerobic baffled reactor and membrane bioreactor are combined.Utilize the organic pollution materials of aerobic baffled reactor in disposing of sewage earlier, when then utilizing membrane bioreactor further to reduce the organic pollutant of sewage, interception inorganic pollution material and pollutent such as bacterium wherein, diaphragm can adopt the hollow fiber ultrafiltration membrane sheet.
The beneficial effects of the utility model are: can thoroughly remove the pollution substances such as organic and inorganic and bacterium in the sewage, make effluent quality reach middle water quality standard, to realize the purpose of water saving, recycling; Have characteristics such as compact construction, floor space are little, flexible arrangement simultaneously, saved mud backflow energy consumption, and can utilize modular design, be convenient to Unit Installation, to be applicable to the sewage disposal requirement in different scales lavatory.
Description of drawings further specifies the utility model below in conjunction with drawings and Examples.
Among the figure: 1, be aerobic baffled reactor; 2, be aerobic reactor zone; 3, be the negative area; 4, be water-in; 5, be membrane treatment appts; 6, be diaphragm; 7, be aerating apparatus; 8, be vacuum pump; The 9th, water outlet; The 10th, the air input channel.
Embodiment
As shown in Figure 1, in the aerobic baffled reactor of some connections, install one group of membrane treatment appts additional, sewage enters aerobic baffling reaction unit (1) by pipeline by (4) water-in, finish organic decomposition by aerobic reactor zone (2) and negative area (3), remove organic pollutant and finish the mud backflow, enter membrane treatment appts (5) then.Several pieces diaphragms (6) are installed in the membrane treatment appts (5), membrane treatment appts (5) bottom is provided with aerating apparatus (7), aerating apparatus (7) is connected with air input channel (10), sewage enters diaphragm (6) under atmospheric effect, diaphragm (6) has been tackled oarse-grained inorganic, part inorganic pollutant and most bacterium, and relies on aerating apparatus (7) to carry out diaphragm (6) cleaning.Membrane treatment appts (5) is outer with pipe connection vacuum pump (8), and the water after will handling by vacuum pump (8) is finished the sewage disposal all processes by water outlet (9) output.
