Abstract
A carbon fiber-composite membrane bioreactor comprises a water distribution box, a water inlet-outlet pump, a liquid level meter, a flow meter, carbon fiber fillers, a hollow fibrous membrane module, an air flow meter, a programmable logic controller (PLC) control system and an aeration machine. The carbon fiber fillers are fixed in the bioreactor, and the running of the whole bioreactor is automatically controlled by the PLC control system. The carbon fiber-composite membrane bioreactor is applied to waste water treatment of a pig farm, good in decontaminating and denitrogenating effect and free of secondary pollution.
Description
Technical field
The utility model is the treatment facility that relates to the piggery wastewater anaerobic digestion solution.
Background technology
Livestock breeding wastewater, particularly large scale of pig farm waste water have become the many geographic primary pollution sources of China.Present most pig farm adopts solid-liquid separation-anaerobic-aerobic to handle excrement and urine water.Membrane bioreactor (MBR) is as a kind of novel and water technology efficiently, and it has stable effluent quality, surplus sludge volume is few, capacity of resisting impact load is strong, be easy to operation automatically and take up an area of advantages such as few.MBR has obtained certain application as the aerobic treatment reactor drum of piggery wastewater anaerobic digestion solution in the laboratory, be not very high but the problem that exists is MBR to the clearance of total nitrogen.
Summary of the invention
The purpose of the utility model is to have the shortcoming that sludge concentration is low, the total nitrogen removal effect is relatively poor when directly handling the pig farm anaerobic digestion solution to membrane bioreactor, and a kind of composite film reactor of handling piggery wastewater is provided.Breeding wastewater is after treatment, and its waste discharge can reach GB18596-2001 " livestock and poultry breeding industry pollutant emission standard ".
The utility model is realized through following technical scheme:
Carbon fiber bar-hybrid mbr is in the MBR reactor drum, to add carbon fiber bar as carrier filler, adopts the carbon fiber bar carrier filler with microbial immobilized cultivation, reaches special process requirements such as denitrogenation, dephosphorization and degradation of organic substances.The intervention of biofilm packing can excite microbic activity, thereby promotes the degraded and the conversion of organic pollutant, nitrogen phosphorus substance etc. in the water.On a section of " microbial film ", by outer and in formed aerobic, amphimicrobian and three kinds of reaction zones of anaerobism.At aerobic zone; Aerobic bacteria is converted into nitrate with ammonia nitrogen; And be converted into carbonic acid gas and water (being converted into the intravital ATP of cell to soluble inorganic phosphorus) to small organic molecule; At anaerobic zone, anerobes is converted into nitrogen and oxygen (larger molecular organics that decomposes difficulty is decomposed into degradable small organic molecule) with nitrate.Final pollution group just is decomposed and changes into the N of effusion water body
2, CO
2And H
2O.Therefore the adding of carbon fiber bar filler more helps the removal of total nitrogen.
This reactor drum mainly is made up of following component: distribution reservoir, intake pump, under meter, aerator, carbon fiber bar filler, hollow fiber film assembly, go out water pump, self-acting valve, PLC housing.
Said carbon fiber bar filler can be the PAN series fiber of being made by the ROHM macrofiber; And the 12000 threads set by 7 microns of diameters through the sizing process special processing forms; In case putting into water just can scatter rapidly; Adding it all has trickle concaveconvex structure on surface separately, can form huge surface-area.
Each components and parts of this reactor drum connect like this:
In membrane bioreactor (5), add and fixed carbon cellulose fiber filler (7); Distribution reservoir (1), intake pump (2), under meter (4) connect successively; Hollow fiber film assembly (8) with go out water pump (10) and be connected, aeration head (6) is arranged on the bottom of reactor drum, pneumatic pump (14) is connected with air flowmeter (9); Liquidometer (3) places the right top of reactor drum, and shore pipe (13) is arranged on the bottom of reactor drum.
The utility model beneficial effect is:
(1) carbon fiber bar-hybrid mbr is the improvement of MBR, and the operating process when it handles waste water is continuous water-in and water-out.Microbial film is fixed on filling surface, has formed the stable ecosystem.Can perch the speed of growth is slow, generation time is long bacterium and higher mikrobe, like nitrifier, so the hybrid mbr method has higher denitrogenation ability.
(2) living weight is many, no excess sludge.In a single day carbon fiber bar is put into water and just can be scattered rapidly, and adding it all has trickle concaveconvex structure on surface separately, can form huge surface-area, can adsorb a large amount of mikrobes, and promptly microbial biomass is many.Simultaneously, because the apposition growth of mikrobe, the microbial film water ratio is lower, and the living weight of reactor drum unit volume can be up to 5～20 times of activated sludge process, so this device processes effect is better.Perching the biology of more higher trophic level on the microbial film, its food chain is than the length among the MBR, and mud is trapped within inside reactor, has reduced the sludge disposal expense.
(3) the carbon fiber bar filler have environment zero load, non-secondary pollution, the infringement of no species, advantage such as safety, light weight, economic durable and effect are remarkable.
(4) can realize full automatic control to hybrid mbr, be convenient to best flow process is selected and debugged.

Embodiment
After carbon fiber bar-hybrid mbr was handled, effluent quality reached GB 18596-2001 " livestock and poultry breeding industry pollutant emission standard " requirement, the COD 100～400mg/L after the film water outlet, NH with certain pig farm anaerobic digestion solution
3-N 40～80mg/L TP5～8mg/L.
The practical implementation process is following:
(1) piggery wastewater through holding back of mechanical grille, is removed macrobead pollution substance and swimmer in the sewage after the sewage collecting pipe network is collected, and waste water gets into methane-generating pit.
(2) waste water flows into methane-generating pit, through efficient anaerobic digestion, after removing most COD acquisition biogas, regulates water quality and quantity through settling tank.
(3) regularly get the water inlet of anaerobic digestion solution as hybrid mbr, system operates to the water of being back to back, through hybrid mbr aerobic/the oxygen nitration denitrification of holding concurrently after, the pollutents such as COD, ammonia nitrogen and phosphorus of removal waste water that can be a large amount of.
