The biological reaction device comprises an anaerobic tank (1) and an aerobic tank (6), wherein a packing layer (2) is formed on the lower part of the anaerobic tank, and the aerobic tank is separated into two sides by a separation wall (4), one of the two sides is an aeration zone (11) in which an aeration distributor (5) is arranged, and the other side is a membrane biological zone in which a membrane bioreactor (8) is arranged. The effluent quality of cultivation wastewater treated by the biological reaction device is high; and the biological reaction device is economical, saves an occupied area and lowers energy consumption.
Description
Technical field
The utility model relates to wastewater treatment equipment, is that a kind of breeding wastewater is handled and the recycling biological reaction apparatus specifically, belongs to technical field of sewage.
Background technology
In recent years, large-scale cultivation industry in China's development rapidly, some large-scale intensive industrialized aquacultures already in Beijing, provinces and cities such as Shanghai, Shenyang and Guangdong, Sichuan have obtained to develop rapidly, and have obtained achievement highly visible.
Because breeding wastewater belongs to high concentrated organic wastewater, adopt aerobic process directly to handle, need dilute waste water, perhaps adopt long hydraulic detention time.This means that the treatment unit volume is big, investment is high; In addition, aerobe technology is directly handled high concentrated organic wastewater, and energy consumption and working cost are higher.The anaerobic-aerobic combination process is the comparatively economic technology of the processing high concentrated organic wastewater of generally acknowledging, UASB-SBR technology, CSTR-SBR technology, IC-SBR technology etc. are generally arranged, and the processing degree of depth of these technologies does not all reach the degree of waste water recycling.If require breeding wastewater is handled the back reuse, then just can achieve the goal in conjunction with the MBR art breading again after the anaerobic treatment.
The utility model content
The purpose of this utility model provide a kind of be intended to make reach reuse after the livestock culturing wastewater treatment and make take up an area of and breeding wastewater that working cost is lower is handled and the recycling biological reaction apparatus.
The breeding wastewater that the utility model provides is handled and the recycling biological reaction apparatus, and it is made of anaerobic pond and Aerobic Pond, and wherein, the bottom of anaerobic pond is packing layer; Aerobic Pond is separated by divider wall, and a side is that the aeration sparger is installed in the aeration zone, and opposite side is installed membrane bioreactor for the film biotic district.
In above-mentioned, water inlet pipe is installed in the bottom of anaerobic pond, and anaerobic pond is positioned at has rising pipe to be communicated with the aeration zone of Aerobic Pond above the packing layer, make waste water flow through packing layer from bottom to top, comes out to enter the aeration zone of Aerobic Pond again from rising pipe.
Back window is arranged at the divider wall bottom, and overflow weir is arranged at the top, forms aeration zone and the biotic waste water circulation passage of film, active sludge and membrane bioreactor circulate repeatedly by back window, biological respinse both having taken place, played the membrane filtration effect again, makes effluent quality reach the purpose of reuse.
The collecting methane pipe is arranged at the anaerobic pond top, and the digestion gas that can collect the anaerobic pond generation is biogas.
Be 1:3 or 1:4 by the separated aeration zone of divider wall and the biotic volumetric ratio of film in the Aerobic Pond, this volumetric ratio is conducive to take full advantage of the membrane biological reaction district to improve reaction efficiency.
The rising pipe of membrane bioreactor connects negative pressure pump, and the negative pressure-pumping effect that makes water outlet pass through negative pressure pump realizes reuse.
The utility model can carry out the anaerobic and aerobic combination treatment, and it is better to handle effluent quality, the main COD of contamination index and the NH of waste water
3The average removal rate of-N reaches 99% and 96% respectively.Because membrane bioreactor has good processed water quality, the water quality of therefore total drainage water is highly stable.The utility model is handled breeding wastewater and recycling and made wastewater treatment and renovation, and is both economical, saves again and takes up an area of and energy consumption.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
With reference to Fig. 1, the breeding wastewater that the utility model provides is handled and the recycling biological reaction apparatus, and it is made of anaerobic pond 1 and Aerobic Pond 6, and wherein, the bottom of anaerobic pond 1 is packing layer 2, fills elastic filler; Aerobic Pond 6 is separated by divider wall 4, and a side is that aeration sparger 5 is installed in aeration zone 11, and opposite side is installed membrane bioreactor 8 for the film biotic district.
In above-mentioned, water inlet pipe 3 is installed in the bottom of anaerobic pond 1, and anaerobic pond 1 is positioned at has rising pipe 12 to be communicated with the aeration zone 11 of Aerobic Pond 6 above the packing layer 2.Back window 7 is arranged at divider wall 4 bottoms, and overflow weir 10 is arranged at the top, forms aeration zone and the biotic waste water circulation passage of film.Collecting methane pipe 13 is arranged at anaerobic pond 1 top, is 1:3 by divider wall 4 separated aeration zones 11 and the biotic volumetric ratio of film in the Aerobic Pond 6, and the rising pipe of membrane bioreactor 8 connects negative pressure pump 9.
Livestock culturing waste water at first enters anaerobic pond 1 by bottom water inlet pipe 3 and produces biogas, and the acid-producing bacteria that anaerobic pond 1 is cultivated and aerogen are to the effect of being hydrolyzed of the organism in the waste water and aerogenesis, and the reduction organic loading; Anaerobic reaction control hydraulic detention time is 40～56 h.Through anaerobic reaction not only the organism of waste water obtain more degraded, and the biochemical of waste water also is improved to some extent, general BOD
5/ COD can improve 0.1～0.2; Waste water enters Aerobic Pond 6 by rising pipe 12 and carries out aerobe reaction then.The direct aeration in 11 bottoms, aeration zone is equivalent to common aeration tank, membrane bioreactor 8 is that membrane module directly is placed in the membrane bioreactor 8 in the film biotic district, membrane module adopts hollow fiber ultrafiltration membrane, and obtain the membrane filtration water outlet by the negative pressure-pumping effect of negative pressure pump, integral type film biological reactor (MBR) has the simple and low advantage of working cost of technology, and the energy consumption of negative pressure pump only is 1/10 of separated type.Active sludge and MBR circulate repeatedly by back window, and biological respinse has both taken place, and play the membrane filtration effect again, make effluent quality reach the purpose of reuse.
This technology has been carried out applied research, water sample result such as the table 1 of selective examination on certain pig farm, south.
