Detailed description of the invention
The two-period form double-face flow-guiding sewage water treatment method of the present invention is to send into treatment sewage to carry out two-part Air Exposure in double-face flow-guiding sewage disposal system, described two-part Air Exposure refers to the first aeration zone and the second aeration zone that the aeration zone partition wall for the treatment of tank is divided into front and back two-part, it is respectively provided with aerator in the bottom of every section of aeration zone, is positioned over the sludge concentration sludge concentration more than the second aeration zone of the first aeration zone.
Realize the two-period form double-face flow-guiding sewage disposal device of the inventive method as shown in Figure 1, including double-face flow-guiding main process pond 1, the double-face flow-guiding plate that is arranged in the main process pond of double-face flow-guiding, by double-face flow-guiding plate, main for double-face flow-guiding process pond is separated into anterior aeration zone and the decanting zone, rear portion 3 that bottom communicates, anterior aeration zone is provided with upright partition wall 4, aeration zone is divided into the first aeration zone 2a and the second aeration zone 2b, the aperture 4a that can pass through sewage is offered on partition wall 4 top, aperture can be installed valve, it is possible to valve is not installed.It is provided with aerator 5 bottom the first aeration zone 2a and the second aeration zone 2b.The aerator of the aerator and the second aeration zone that are arranged at the first aeration zone can share an air inlet pipe, it is also possible to is respectively configured each independent air inlet pipe 11a, 11b to realize independently controlling.It is positioned over the sludge concentration of the first aeration zone 2a sludge concentration more than the second aeration zone 2b, first aeration zone sludge concentration is high, can strengthening aeration rate, improve disposal ability and treatment effect, sludge concentration and aeration rate can be adjusted to the sludge settling effect being best suitable for decanting zone by the second aeration zone.In decanting zone, rear portion 3, upper rear end is provided with effluent weir 6, is provided with the aqueduct 7 drawn by water bottom effluent weir.It is flat at the bottom of the pond of the anterior aeration zone in double-face flow-guiding of the present invention main process pond 1, is at the bottom of the slope gradually risen from front to back at the bottom of the pond of decanting zone, rear portion 4.Be conducive to sedimentation and the backflow of mud.Described double-face flow-guiding plate is made up of the outstanding vertical front flow guiding plate 8a being loaded on above at the bottom of pond and rear deflector 8b and the vertical clapboard 8c between front flow guiding plate and rear deflector, and the top of vertical clapboard and bottom are respectively lower than the top of front flow guiding plate and rear deflector and bottom thus forming inverted U sludge reflux passage 8d.
During present device work, by suction pump, from aqueduct 9, treatment sewage being introduced the main process pond 1 of double-face flow-guiding, sewage at the first aeration zone 2a, flows into the second aeration zone 2b by the aperture 4a on partition wall 4 and again carries out Air Exposure after Air Exposure.The water quality crossed through secondary Air Exposure is substantially up to standard, but the mixed liquor of removing contamination being mixed with activated sludge needs to separate mud with clear water.Mixed liquor of removing contamination flows in decanting zone, rear portion 3 under the effect of current from deflector, owing to decanting zone could not be stirred by aeration, sludge settling is bottom decanting zone, when mud top exceeds the bottom of deflector 8b, mud inverted U sludge reflux passage 8d in double-face flow-guiding plate in top is back to the second aeration zone, and clear water then automatically flows into follow up device from the effluent weir 6 aqueduct 7 through bottom.Unnecessary activated sludge can be extracted out by sludge pump 12a, 12b of being arranged at bottom the first aeration zone and the second aeration zone respectively and carry out processed outside pond.
