The structural representation of the integrated sewage treating apparatus that Fig. 1 provides for the embodiment of the present invention;
Fig. 2 is the A-A sectional view of Fig. 1;
Fig. 3 is the B-B sectional view of Fig. 1.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
As Fig. 1-Fig. 3, the embodiment of the present invention provides a kind of integrated sewage treating apparatus, comprise a cylindrical housings (to illustrate, non-label), the upper end of described cylindrical housings is provided with access hole 8 and vapor pipe 9, described cylindrical housings inside has anaerobic room 1, anoxic room 2, aerobic room 3, mixing section 4 and settling chamber 5, described anaerobic room 1 is positioned at the position, middle of described cylindrical housings inside, described settling chamber 5 is positioned at the outer region of described cylindrical housings inside, rest part in described cylindrical housings is anoxic room 2 and aerobic room 3, region between wherein said settling chamber 5 and anaerobic room 1 is anoxic room 2, described aerobic room 3 is positioned at opposite, described anoxic room 2, be mixing section 4 between described anoxic room 2 and described aerobic room 3.
As Fig. 1-Fig. 3, the bottom of described anaerobic room 1 is provided with water inlet pipe 12, is provided with anaerobic room dividing plate posticum 10 in described anaerobic room 1.Without cutting off between described anoxic room 2 and described aerobic room 3 and described mixing section 4, and naturally being distinguished by dissolved oxygen gradient in water body, that is to say that the gradient automatic distinguishing by dissolved oxygen in water body between three is opened.Be provided with dividing plate prosopyle, settling chamber 11 in described settling chamber 5, the bottom of described settling chamber 5 is provided with sludge bucket 18, and the mid-way of described settling chamber 5 is provided with inclined tube 20, is provided with water leg 6 above described inclined tube 20, and described water leg 6 is connected with rising pipe 13.Sludge pipe 15 is provided with below described sludge bucket 18, described sludge pipe 15 is connected with excess sludge discharge pipe 17, excess sludge discharge valve 16 is provided with between described sludge pipe and described excess sludge discharge pipe 17, described sludge pipe 15 is also connected with described water inlet pipe 12, and is provided with returned sluge variable valve 14 between the two.In addition, the bottom of described aerobic room 3 is provided with the aeration tube 19 be connected with the external world; The both sides of the edge place of described anoxic room 2 is also provided with flow deflector 7.Mud mixture in described anoxic room 2 is by the mud mixture mixing in described flow deflector 7 and described aerobic room 3.
As Fig. 1-Fig. 3, the concrete principle of described integrated sewage treating apparatus is as follows: the sewage in life enters anaerobic room 1 by water inlet pipe 12, form mud mixture, anaerobic room 1 is by the anaerobic room dividing plate posticum 10 on its top, mud mixture is delivered to anoxic room 2 again, because between anoxic room 2 and aerobic room 3 and mixing section 4, nothing is cut off, can naturally be distinguished by dissolved oxygen gradient in water body, mud mixture in described anoxic room 2 is mixed in mixing section 4 further by the mud mixture in described flow deflector 7 and described aerobic room 3, and after carrying out denitrification nitrogen and phosphorus removal, described settling chamber 5 is entered by dividing plate prosopyle, described settling chamber 11, inclined tube 20 is provided with in settling chamber 5, mud mixture is after inclined tube 20 precipitates, clear water above enters in rising pipe 13 by water leg 6, mud after precipitation is after sludge bucket 18 is collected, enter in sludge pipe 15, amount of activated mud enters again together in anaerobic room 1 with the sewage at water inlet pipe 12 place after described returned sluge variable valve 14, excess sludge enters in excess sludge discharge pipe 17 through excess sludge discharge valve 16, thus outside periodicity discharge system.Wherein, this active sludge is granule sludge, and the more general activated sludge process of sludge yield coefficient is low, can periodically be discharged by sludge pipe 15.
Integrated sewage treating apparatus of the present invention adopts activated sludge process to carry out advanced treatment to sewage, and carry out mud-water separation by tube settling, effectively can remove the nutritive substance such as nitrogen, phosphorus in sanitary sewage, amount of activated mud after separation enters processing unit again, and system spare sludge yield is low.
