Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the present invention is further detailed explanation.
Fig. 1 is structural representation of the present invention.As shown in the figure, fibre bundle filtration membrane biological reaction apparatus of the present invention comprises biological reaction tank 1 and without constraint fiber bundle filter system.Wherein, biological reaction tank 1 comprises water-in 14, aeration opening 15 and water outlet, has been covered with the bacterium for degradation of organic substances in biological reaction tank.
Without constraint fiber bundle filter system comprise be connected in biological reaction tank water outlet without constraint fiber bundle filter 2, this comprises without constraint fiber bundle filter 2 the fibrous bundle accumulation horizon 4 being formed by some fibrous bundle free accumulation on lower barrier, lower porous plate 5 and the lower porous plate 5 of container 3, container 3 interior bottoms, and container 3 is provided with lower outlet 6.
Also comprise air water backwash import 7 and the first self-acting valve 8 without constraint fiber bundle filter system, this air water backwash import 7 is connected with lower outlet 6 by this first self-acting valve 8.
Also comprise finished product water pump 9, the second self-acting valve 10 and the 3rd self-acting valve 11 without constraint fiber bundle filter system, lower outlet 6 is connected with finished product water out 12 by finished product water pump 9 and the second self-acting valve 10; Lower outlet 6 is connected with wash-down water recovery tube 13 by finished product water pump 9 and the 3rd self-acting valve 11.
The working process of fibre bundle filtration membrane biological reaction apparatus of the present invention is:
Pending sewage enters biological reaction tank 1 by water-in 14, and the air that outside is pressed into enters biological reaction tank 1 via aeration opening 15, to maintain organic degraded in the normal breeding of bacterium in biological reaction tank 1 and water; Now the first self-acting valve 8 is closed, and finished product water pump 9 turns round, and the second self-acting valve 10 is opened, and lower outlet 6 places present negative pressure, and water in biological reaction tank 1 is through the filtration without constraint fiber bundle filter 2, discharges after becoming clear water from finished product water out 12;
Along with water pollutant is in the accumulation gradually on fibrous bundle accumulation horizon 4 surfaces, the water yield at finished product water out 12 places declines gradually, and in the time dropping to certain value, fibre bundle filtration membrane biological reaction apparatus proceeds to back flushing state automatically.Under this state, finished product water pump 9 shuts down, the second self-acting valve 10 and the 3rd self-acting valve 11 are closed, and the first self-acting valve 8 is opened, pressurized air and backwashing water enter the bottom of container 3 via air water backwash mouth 7, and upwards promote fibrous bundle accumulation horizon 4, make to be separated from each other between each fibrous bundle, and upwards rise, stir, collide, dirt comes off from fibrous bundle surface immediately; Meanwhile, the pressurized air being entered by aeration opening 15 is still continuing, and the water of container 3 peripheries is still in flowing and seething state, and therefore, the dirt major part coming off from fibrous bundle is all along with the backwashing water moving upward flow back in the water body of biological reaction tank 1;
In the final stage of back flushing, for fear of the dirt finished product water out that bleeds, must accelerate the discharge rate of container 3 interior dirts, so that internal tank is cleaned out, this just need to carry out for some time of after in back flushing, and the water containing dirt that lower outlet 6 places are flowed out is transmitted back in biological reaction tank 1 through wash-down water recovery tube 13.Now, as long as the first self-acting valve 8 and the second self-acting valve 10 are closed, open finished product water pump 9 and the 3rd self-acting valve 11 simultaneously, like this, under the suction function of finished product water pump 9, the wash-down water that contains dirt in container 3 can discharge fast and get back in biological reaction tank 1 via wash-down water recovery tube 13;
After back flushing finishes, obtained purification for the fibrous bundle that filters dirt, device comes back to the normal operating conditions of filtering sewage, and can not cause the obstruction of strainer, and can maintain enough density and the normally breedings of bacterium in biological reaction tank, to ensure organic degraded in water.
In addition, in backwash process, for preventing the loss of fibrous bundle, can upper barrier and upper porous plate 16 be set in container 3 internal upper parts, to stop that fibrous bundle seethes in biological reaction tank 1; In the time that needs are changed fibrous bundle accumulation horizon 4, as long as upper barrier and upper porous plate 16 are unloaded, the fibrous bundle of free accumulation is taken out and changed, operate very simple.Separately in view of the life cycle of fibrous bundle is longer, thereby normal operation that also can assurance device without frequent replacing and non-blockage phenomenon.The fibrous bundle using has two kinds of structure formations, the first is that the two ends of fibrous bundle are broken into fast knot, fibrous bundle length determines according to volume size and the filtered water flow of container 3, the second is the fibrage slabbing of pencil or the fabric of bar shaped, and its area and thickness decide according to the volume size of container 3.
According to the actual needs, can be arranged at the inside of biological reaction tank 1 without constraint fiber bundle filter 2, also can be arranged at the outside of biological reaction tank 1, as long as be connected to the water outlet of biological reaction tank 1, can filter the water after degraded.Specifically, if be built in biological reaction tank 1 without constraint fiber bundle filter 2, need to ensure that lower outlet 6 is communicated with the water outlet sealing of biological reaction tank 1; If be placed on biological reaction tank 1 without constraint fiber bundle filter 2, be provided with water-in on without constraint fiber bundle filter 2, on this, water-in is communicated with the water outlet sealing of biological reaction tank 1.
Fibre bundle filtration membrane biological reaction apparatus of the present invention, to connect one without constraint fiber bundle filter in the water outlet of biological reaction tank, this is without being equiped with the fibrous bundle accumulation horizon being formed by some fibrous bundle free accumulation in constraint fiber bundle filter, filter by this fibrous bundle accumulation horizon, not only can reach good filter effect, and without power operation, very simple when cleaning, changing.The present invention is simple in structure, be easy to clean, long for the fibrous bundle life cycle of filtering, thereby can reduce production and maintenance cost.
The above is preferred embodiment of the present invention and the know-why used thereof; for a person skilled in the art; in the situation that not deviating from the spirit and scope of the present invention; any apparent change such as equivalent transformation, simple replacement based on technical solution of the present invention basis, within all belonging to protection domain of the present invention.
