Detailed description of the invention
Below in conjunction with accompanying drawing, some embodiments of the present invention are further introduced, but be not intended to limit protection scope of the present invention.
Fig. 4 is the structural representation of an embodiment of the biological sewage treatment device according to the present invention, wherein said biological sewage treatment device is standing form, including anaerobic reaction room (31), aerobic reaction room (25), separation chamber (22) and the power house (3) that is arranged in anaerobic reaction room (31). These unit are all disposed within single cylindrical tower (or polygon tower) (tower that such as 10-30 rice is high).
The bottom of power house (3) is provided with air inlet (6). Air inlet (6) has the air inlet pipe (7) downwardly extending and leading to outside to allow extraneous air to enter power house (3). Air inlet (6) be arranged over cover plate (5) so that operative employee is movable in the power house (3). The edge of cover plate (5) is provided with air outlet (4) to allow the air from air inlet (6) to enter power house (3) the power-equipment that optionally leads.
The top of power house (3) is provided with gas outlet (12). In some cases, the top of power house (3) can be a part for dividing plate (28)). The lower entrances of gas outlet (12) and heat exchanger (13) is in fluid communication. It is internal that heat exchanger (13) is positioned at aerobic reaction room (25). From the gas of air vent (12) in heat exchanger (13) by and carry out heat exchange with the mixed liquor in aerobic reaction room (25), then discharge from the outlet (15) at heat exchanger (13) top. In some cases, outlet (15) place can arrange blower fan (such as axial flow blower) to strengthen gas flowing in power house (3) and heat exchanger (13). Heat exchanger (13) in biological sewage treatment device shown in Fig. 4 can be single straight heat exchange of heat pipe (13) as shown in Figure 1, and wherein in pipe, gas carries out heat exchange with managing outer mixed liquor;Can also being many tubular heat exchangers (13) as shown in Figure 2, wherein the gas in tubulation carries out heat exchange with managing outer mixed liquor; Can also is that coil heat exchanger (13) as shown in Figure 3, wherein in pipe, gas carries out heat exchange with managing outer mixed liquor.
Sewage charging from water inlet pipe (9) enters anaerobic reaction room (31) after sewage inlet valve (8) and pump (1). Sewage charging can form laminar flow upwards in anaerobic reaction room (31), mud in anaerobic reaction room (31) is stably suspended thus forming mud bed in the balance of flowing and sedimentation, and at this moment anaerobic reaction room (31) just become up-flow sludge bed reactor. Continue up the clear liquid of flowing through mud bed and enter aerobic reaction room (25) by opening (29) on dividing plate (preferably have unidirectional pass through device). Optionally, gas collector (such as the gas skirt described in US6,063,273) (not shown) can be arranged below to collect the gases such as the methane of anaerobic reaction generation in dividing plate (28). Clear liquid enters aerobic reaction room (25) and mixes with aerobic mixed liquor therein afterwards. When needed, sewage charging can also mix with the anaerobism mixed liquor in anaerobic reaction room (31), mixes subsequently into aerobic reaction room (25) and with aerobic mixed liquor therein.
Aerating gas enters aerobic reaction room (25) through air inlet pipe (10), Aeration fan (30) and aeration distributor (27) and mixed liquor therein is carried out Air Exposure. Any suitable aerator also can be set in aerobic reaction room (25), for instance spiral aerator, micro-hole aerator, board-like aerator, rotation mixed aerator, tube aerator, jetting type aerator etc. After aeration, the mixed liquor of aerating gas leaves from the top of aerobic reative cell (25) and enters, through pipeline (23), the gas-liquid separator inner core (19) being arranged in separation chamber (22) and carries out gas-liquid separation. The gas separated is discharged from the top of gas-liquid separation chamber (22), the mixed liquor separated carries out mud-water separation from flowing downwardly in separation chamber (22) between gas-liquid separator inner core (19) and urceolus (18), the supernatant separated is discharged as water outlet (20) from overflow launder (21), and the concentration mixed liquor of separation leaves from the bottom of separation chamber (22) and passes through concentration mixed-liquor return pipe (26) and returns to the bottom of aerobic reaction room (25). When needed, it is possible to open concentration mixed-liquor return valve (11) and pump (1) makes the concentration concentrated mixed-liquor return pipe (14) of mixed liquor, reflux inlet (11) and pump (1) at least partly enter anaerobic reaction room (31).
During biological sewage treatment device operates, gas in the heat power house (3) that pump (1) and blower fan (30) produce, the gas of heating rises through gas outlet (12) and enters heat exchanger (13), heat exchanger (13) carries out heat exchange with the mixed liquor in aerobic reaction room (25), then discharges from outlet (15). The mixed liquor of heating can carry out aerobic reaction better in aerobic reaction room (25). Thus present invention achieves the recycling of the such as heat that the power-equipment of pump (1) and blower fan (30) discharges in power house (25).
Additionally, power house (3) to be arranged on the inside of anaerobic reaction room (31) so that whole biological sewage treatment device outward appearance becomes more succinct and compact, is easy to manipulation, takes up an area less, is easily installed and transports.Meanwhile, the supervising devices such as the power-equipment laid and measuring instrument, control switch and valve are concentrated to be also beneficial to convenient, to monitor biological sewage treatment device quickly and efficiently operation.
The present invention is described above by the mode illustrated. It is understood, however, that the present invention is never only limited to these detailed description of the invention. The present invention can be carried out various amendment or variation by those of ordinary skill, and these amendments and variation broadly fall into protection scope of the present invention.
