Problems solved by technology

[0004] Regarding the related technologies mentioned above, the inventor believes that in order to improve the efficiency of sewage treatment, the flow rate or flow of sewage will be increased as much as possible, but it will also lead to anaerobic ponds or The treatment burden of the contact oxidation tank increases, and it appears that the sewage discharged from the anaerobic tank still contains a lot of macromolecular organic matter, which makes it difficult for the subsequent contact oxidation tank to remove the macromolecular organic matter, or, the discharge of the contact oxidation tank The sewage still contains more organic matter in the sewage, so as to affect the treatment effect of the subsequent MBR pool

Embodiment 1

[0051] The implementation principle of Example 1 is as follows: the sewage first enters the regulating tank 11 and the electrolytic tank 12, and the electrolytic tank 12 can degrade a part of the non-degradable COD, so as to improve the biodegradability of the sewage and facilitate subsequent treatment; then the sewage enters the first anaerobic tank. In the tank 13 and the second anaerobic tank 14 to remove macromolecular COD, and then enter the first controllable aeration tank 15 and the second controllable aeration tank 16 (in intermittent aeration state) to remove BOD and small molecules. Molecular COD, the contact oxidation tank 17 mainly decomposes the organic matter into inorganic matter, and the MBR tank 18 and the sedimentation tank 19 further remove the particles and sludge in the sewage, so that the water quality meets the standard.

[0052] When the flow of sewage increases, resulting in an increase in the treatment pressure of the anaerobic tank, the first controll...

Embodiment 2

[0053] Embodiment 2, on the basis of embodiment 1, the following settings are made, such as image 3 As shown, a reversing pipe 152 is provided between the first controllable aeration tank 15 and the second controllable aeration tank 16. Specifically, the reversing pipe 152 is a telescopic hose, and the two ends of the reversing pipe 152 extend respectively. into the first controllable aeration tank 15 and the second controllable aeration tank 16 .

[0054] When the oxygen content of the first controllable aeration tank 15 or the second controllable aeration tank 16 is required, and it is not necessary to supply oxygen to another controllable aeration tank, one end of the reversing pipe 152 can be connected to The spray end of the controllable aerator 151 of the controllable aeration tank in the anaerobic state can be in the form of screw connection, socket connection, clip connection, etc. At this time, the controllable aerators 151 of the two controllable aeration tanks Wor...

Embodiment 3

[0055] Embodiment 3, on the basis of embodiment 1, make the following settings, as Figure 4 , Figure 5 As shown, the hollow fiber membranes 24 are arranged vertically and horizontally in the horizontal plane 452, and the suction pipes 25 corresponding to a row of the horizontal hollow fiber membranes 24 are set to two, and the two suction pipes 25 are arranged in parallel up and down; The upper end of 24 is fixedly connected with the suction pipe 25 located above, that is, the fixed end, and the upper port of the hollow fiber membrane 24 is communicated with the inner cavity of the suction pipe 25 located above; The access hole communicated with the lower port of the hollow fiber membrane 24, specifically, a rotary head 251 is rotatably connected in the access hole, the rotary head 251 is hollow, the inner cavity of the rotary head 251 is communicated with the inner cavity of the suction pipe 25, and the hollow The lower end of the fiber membrane 24 is sleeved and fixed on ...

Abstract

The invention relates to an efficient treatment system for household garbage leachate, which comprises a regulating tank, an electrolytic tank, a first anaerobic tank, a second anaerobic tank, a first controllable aeration tank, a second controllable aeration tank, a contact oxidation tank and an MBR (membrane bioreactor) tank which are sequentially connected, the MBR tank is connected with a discharge pipeline and a sedimentation tank, and the inlet end and the discharge end of the sedimentation tank are both connected with the MBR tank; filler and controllable aerators are arranged in the first controllable aeration tank and the second controllable aeration tank. By arranging the first controllable aeration tank and the second controllable aeration tank, the intermittent aeration state, the continuous aeration state and the non-aeration state are switched according to the water quality condition, so that the controllable aeration tanks realize anaerobic and aerobic treatment, the treatment burden of the anaerobic tank and the contact oxidation tank is reduced, and the sewage treatment efficiency and the treatment effect are improved.

Description

technical field [0001] The present application relates to the field of sewage treatment, in particular to a system for efficient treatment of domestic garbage leachate. Background technique [0002] With the development of social and economic level, people's living standards are improving day by day, which produces a lot of domestic garbage, and these domestic garbage often need to be transported to garbage transfer station for pretreatment, so that garbage and domestic garbage leachate are separated, and then pass through The waste water treatment plant treats the domestic waste leachate. [0003] Existing wastewater treatment devices include conditioning tanks, anaerobic tanks, contact oxidation tanks, and MBR tanks. The anaerobic tank is mainly used to convert macromolecular organic matter into low-molecular organic matter that is easily degraded, that is, to improve the COD removal rate and contact oxidation. The pond mainly decomposes organic matter into inorganic matt...
