The structural representation of the Buffer Pool for the hydrolysis of granule debirs that Fig. 1 provides for the embodiment of the present invention.
Detailed description of the invention
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, other embodiments all that those of ordinary skill in the art obtain under the prerequisite not making creative work, all belong to the scope of protection of the invention.
As Fig. 1, the embodiment of the present invention provides a kind of Buffer Pool for the hydrolysis of granule debirs, for storing and hydrolysis organic wastewater, comprise first-level buffer pond 1 for storing described organic wastewater and level 2 buffering pond 2 and three grades of Buffer Pools 3 for being hydrolyzed to described organic wastewater.Described first-level buffer pond 1 is connected with organic wastewater water source by water inlet pipe 4, and described three grades of Buffer Pools 3 are connected with outlet pipe 5; Described first-level buffer pond 1 is connected by divider wall with level 2 buffering pond 2, described divider wall is provided with electric gate valve 6, submerged sewage pump 7 is provided with bottom described level 2 buffering pond 2, described submerged sewage pump 7 is connected with described three grades of Buffer Pools 3 by intermediate conduit 8, is provided with heating plant in described three grades of Buffer Pools 3.The wastewater flow rate of described organic wastewater water source generation per hour is Q, and the described organic wastewater hydrolysis cycle is t hour, and the volume in described level 2 buffering pond 2 is greater than Q*t.Wherein, described first-level buffer pond 1, level 2 buffering pond 2 and three grades of Buffer Pools 3 are reinforced concrete structure; Described intermediate conduit 8 can be flexible pipe, and intermediate conduit 8 and three grades of Buffer Pool 3 junctions seal and arrange.The object arranging divider wall makes organic wastewater stop time enough in first-level buffer pond 1, to make the large particulate matter in organic wastewater precipitate in first-level buffer pond 1, to avoid the pipeline of this large particulate matter clogging submerged sewage pump 7; Described electric gate valve 6 is for being communicated with this two Buffer Pools, and the flashboard diameter of this electric gate valve 6 is comparatively large, facilitates organic wastewater to enter in level 2 buffering pond from first-level buffer pond 1; For ensureing sedimentation effect, this electric gate valve 6 should be located at more than the middle part of divider wall.Obviously, the device that the large particulate matter in organic wastewater can be made to carry out precipitating in first-level buffer pond 1 all can be used for the present embodiment, such as, the completely open docking in first-level buffer pond 1 and level 2 buffering pond 2 can be set, the screen pack that described large particulate matter can be filtered is set between first-level buffer pond 1 and level 2 buffering pond 2.In addition, described heating plant is earth source heat pump, in the present embodiment, controls temperature in three grades of Buffer Pools 3 at 30 ~ 35 DEG C, the stable temperature provided needed for hydrolytic process.
During actual use, because organic wastewater hydrolysis needs the regular hour, if its hydrolysis cycle is t hour, within this cycle, organic wastewater water source still constantly produces new organic wastewater, if the wastewater flow rate of its generation per hour is Q, then in this cycle, the wastewater flow rate of Q*t should be able to be received in first-level buffer pond 1 and level 2 buffering pond 2.For ensureing the continuation of hydrolytic process, be preferably within the hydrolysis cycle, the organic wastewater amount of hydrolysis is identical with the organic wastewater amount newly produced, and therefore needs to ensure that each level 2 buffering pond 2 is Q*t to the organic wastewater amount that three grades of Buffer Pools 3 provide.And be ensure that submerged sewage pump 7 is in below liquid level all the time, the volume that should arrange level 2 buffering pond 2 is at least the wastewater volume sum in Q*t and submerged sewage pump 7 place altitude range.Preferably, described first-level buffer pond 1, level 2 buffering pond 2 are identical with the volume of three grades of Buffer Pools 3, can realize the continuation of hydrolytic process.In actual use procedure, the debirs kind produced due to different places is different, and the hydrolysis cycle is also different, and therefore the volume of Buffer Pool also should be designed to difference as the case may be.
