Example Embodiment

[0025] Example 1

[0026] like figure 1 , figure 2 As shown in the figure, an integrated treatment equipment for rural high-concentration COD and ammonia nitrogen aquaculture sewage of the present invention includes a UASB reactor 1, an anoxic tank 2, an aerobic tank 3, an activated carbon filler tank 4, an MBR reaction tank 5 and a disinfection tank connected in sequence. Pool 6, a reaction zone 7 is provided inside the UASB reactor 1, a water storage zone 8 is provided outside the reaction zone 7, a sludge settling zone 71 is provided at the lower part of the reaction zone 7, and suspended sludge is provided above the sludge settling 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, and overflow weirs 732 communicated with the water storage zone 8 are provided on both sides of the separation zone 73. The UASB reactor The lower part of 1 is provided with...

Example Embodiment

[0034] Example 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. In the UASB reactor 1, about 60% of the COD is removed, and the macromolecular organic matter that is difficult to degrade is decomposed into simple molecular structures. , molecular structure with better biochemical properties, in UASB reactor 1, the residence time of sewage is about 16 hours, the generated methane (CH4) gas overflows through the three-phase separator 731, the generated sludge sinks, and the initial treatment The last sewage is discharged through the overflow weir 732 and enters the anoxic tank 2; the anoxic tank 2 is equipped with a first filler 12, and the first filler 12 provides a place for the growth of microorganisms. Biomass and sewage undergo partial COD removal and denitrification and denitrification in anoxic tan...

[0037] Example 3

[0038] In embodiment 2, the effect of aquaculture sewage treatment 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 quality is shown in Table 2.

[0041] Table 1 Influent water quality indicators

[0042] Monitoring items

[0043] Table 2 Effluent water quality indicators

[0044] Test items

[0045] It can be seen from the data in Table 1 and Table 2 that the water quality of the treated water after treatment by the integrated treatment equipment for high-concentration COD and ammonia-nitrogen aquaculture sewage in the present invention conforms to one of GB18918-2002 "Pollutant Discharge Standards for Urban Sewage Treatment Plants". Grade A standard.

[0046] The invention is an integrated treatment equipment for rural high-concentration COD and ammonia nitrogen aquaculture sewage, which is designed for the water quality ...

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 ...
