Embodiment 1

[0026] Such as figure 1 , figure 2 As shown, a kind of rural high concentration COD of the present invention, ammonia-nitrogen farming wastewater integrated treatment equipment, comprises UASB reactor 1, anoxic pool 2, aerobic pool 3, activated carbon packing pool 4, MBR reaction pool 5 and disinfection pool 6, UASB reactor 1 is provided with a reaction zone 7 inside, a water storage zone 8 is provided outside the reaction zone 7, a sludge settlement zone 71 is provided at the lower part of the reaction zone 7, and a suspended sludge is provided above the sludge settlement zone 71 Zone 72, a separation zone 73 is provided above the suspended sludge zone 72, a three-phase separator 731 is provided on the upper part of the separation zone 73, overflow weirs 732 communicated with the water storage zone 8 are provided on both sides of the separation zone 73, UASB reactor The lower part of the reactor 1 is provided with a sewage inlet 9, which communicates with the sewage input p...

Embodiment 2

[0035] The technological process of embodiment 1 is as follows:

[0036] According to the embodiment of Example 1, the specific implementation process of the present invention: the sewage first enters the UASB reactor 1, and in the UASB reactor 1, about 60% of COD is removed, and the macromolecular organic matter that is difficult to degrade is decomposed into a simple molecular structure , Molecular structure with better biochemical properties. In UASB reactor 1, the residence time of sewage is about 16 hours, and the generated methane (CH4) gas overflows through the three-phase separator 731, and the generated sludge sinks, while the initial treatment The final sewage is discharged through the overflow weir 732 and enters the anoxic pool 2; the first packing 12 is housed in the anoxic pool 2, and the first packing 12 provides a place for microbial growth, and the microbes hang a film on the surface of the first packing 12, increasing Biomass, sewage in the anoxic pool 2 for ...

Embodiment 3

[0038] The effect of aquaculture sewage treatment in embodiment 2 is as follows:

[0039] Sewage treatment plan:

[0040] The treated water volume is 20 tons / day, the influent water quality is shown in Table 1, and the effluent water quality is shown in Table 2.

Abstract

The invention discloses integrated treatment equipment for rural aquaculture sewage with high-concentration COD (Chemical Oxygen Demand) and ammonia nitrogen and relates to the technical field of sewage treatment equipment. The integrated treatment equipment comprises a UASB (Upflow Anaerobic Sludge Blanket) reactor, an anoxic pool, an aerobic pool, an active-carbon filler pool, an MBR (Membrane Bioreactor) reaction pool and a disinfection pool which are connected in sequence, wherein a sewage inlet is arranged at the lower part of the UASB reactor, and the UASB reactor is communicated with the anoxic pool by a first water outlet; the anoxic pool is communicated with the aerobic pool by a second water outlet; the aerobic pool is communicated with the active-carbon filler pool by a third water outlet; the active-carbon filler pool is communicated with the MBR reaction pool by a fourth water outlet; the MBR reaction pool is communicated with the disinfection pool by a fifth water outlet,and a treated-water outlet is arranged at the lower part of the disinfection pool. The integrated treatment equipment disclosed by the invention is designed according to the water-quality characteristics of high COD, high ammonia-nitrogen content, high total-nitrogen content and poor biochemical property and the like in the rural aquaculture sewage, and the problems of difficult treatment and badtreatment effect of the aquaculture sewage due to high-concentration COD and high ammonia nitrogen in the existing rural aquaculture sewage are solved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment equipment, in particular to an integrated treatment equipment for high-concentration COD and ammonia nitrogen farming sewage in rural areas. Background technique [0002] At present, in the process of raising pigs, chickens, ducks and other farm animals in rural farms, a large number of medicines for disease treatment and health care are usually used. The medicines include antibiotics, which will lead to poor biodegradability of the sewage discharged from the farms. It is difficult to deal with. In addition, the high concentration of COD and high ammonia nitrogen in aquaculture sewage will also increase the difficulty of aquaculture sewage treatment. With the strengthening of the country's awareness of rural environmental protection and the country's decision to revitalize the rural economy and build a beautiful village, the treatment of rural farming sewage is imminent. [0003] Small ...
