Subsequent grid water outlet enters regulating reservoir, and it acts on uneven, the balanced water quality that regulation carrys out water, is used because villager lives The characteristics of water, it is uneven to measure small and different periods discharge capacity, basic law be it is early, middle and late be peak period, weekend arranges compared with working day It is high-volume big, thus water quality has larger fluctuation, it is essential to set regulating reservoir, follow-up each PROCESS FOR TREATMENT section is normally connected Reforwarding turns.Aerating system is set at regulating reservoir bottom simultaneously, limited aeration is carried out to regulating reservoir by micro-hole aerator, controls tolerance It is unsuitable excessive, play uniform stirring, the effect of regulating water quality water, and liquid level be provided with water level controller can effectively carry out from Water level function is monitored and controlled in dynamicization.
Regulating reservoir water outlet is pumped most crucial into the sanitary sewage disposal and reclaiming system by intake pump (submersible sewage pump) Traditional A/O techniques are combined by technique unit reaction tank, the technique with MBR membrane bioreactors, and this group technology can be efficiently Nitrifier is retained, will not be lost in water outlet, and relatively independent living environment is provided for nitrifier and denitrifying bacterium, while is existed again Filler is added in anaerobic reation pool and aerobic reaction tank, the microorganism for forming suspension growth and apposition growth is coefficient compound Bioreactor, microorganism are able to remain in high concentration in biochemical reaction tank, improve sludge concentration in aerobic section, can Up to 2-7 times of traditional activated sludge process.
Regulating reservoir water outlet enters anaerobic reation pool, is sufficiently mixed with the mixing nitrification liquid of aerobic reaction tank backflow, utilizes life Organic matter and activated sludge endogenous metabolism in sewage living carry out denitrification, remove the nitrate nitrogen in sewage.In anaerobic reation pool Floating stuffing is directly launched, generally spherical PE/PP materials, its proportion is close to water, and free movement collision, is carried under flow action For the apposition growth of microorganism, dosage is generally the 30% of pond appearance.Mixing plant is provided with pond simultaneously, is taking into full account filler Influence, from vertical axis, the mixer of the slow-speed of revolution, to make sludge prevent from precipitating in suspension, and be more beneficial for biofilm, simultaneously The conditions warrant of the Constant hypoxia denitrification percent of anaerobic reation pool is provided.
Water outlet, which enters, after anaerobic reation pool denitrification carries out aerobic nitrification reaction in aerobic reaction tank, combined type is added in pond Filler, generally PE ring plate+polyvinyl silk, specific surface area is big, easy to be filmed, positive effect.Bottom of pond sets micro-pore aeration system simultaneously (microporous diaphragm aerator) continuous aeration, by gas flowmeter and gas valve regulation aeration quantity, because attached state be present in pond Microorganism, the more general activated sludge process of dissolved oxygen concentration is high in pond, controls big in sewage after 3mg/L or so, nitration reaction Partial organic substances and ammonia nitrogen are degraded.Fluid level controller is provided with aerobic reaction tank, to control to adjust the water outlet in pond, maintains film life Constant liquid level in thing reaction tank.A part of mixed liquor is back to front end anaerobic reation pool by reflux pump in aerobic reaction tank Bottom, return current ratio of the mixed liquid take 200-300%.
Aerobic reaction tank water outlet enters membrane biological reaction pond, and substituting traditional sedimentation basin by MBR membrane modules realizes solid-liquid Centrifugation, micro-filtration membrane aperture select 0.1-0.4um, efficient detention SS and effectively extend sludge retention time, the dirt in membrane cisterna Up to 8000-20000mg/L, pollutant is further degraded and removed in membrane cisterna mud concentration.MBR membrane module structure forms can Using hollow-fibre membrane and the major class of Flat Membrane two, hollow-fibre membrane cost is low compared with Flat Membrane, but easily blocks, easy fracture of wire, Flat Membrane Service life up to 5-10, be 3-5 times of hollow-fibre membrane.In terms of cleaning angle, hollow-fibre membrane needs frequent clean, and Need to clean offline, and Flat Membrane then 6-12 months/time, can on-line cleaning, it is small to later stage operation maintenance work difficulty.Membrane cisterna bottom It is provided with boring aeration pipe (tube wall both sides are separated by downwards 45 ° of perforates) and carries out continuous aeration, passes through gas flowmeter and gas trap Adjust aeration quantity.
Finally, membrane module production water is evacuated to middle pond using self priming pump, as the water outlet for stopping and caching biochemical reaction, in pond Setting claustra formula folded plate partition wall to further enhance, pollution removes and Disinfection Effect, water quality index can reach《Regeneration of urban sewage profit With urban reclaimed water water standard》(GB/T18920-2002) reuses such as green area irrigation, Street surface cleaning or directly up to standard can, be carried out Discharge.Water flow meter, magnetic valve and pressure gauge, flowmeter monitoring water flow, magnetic valve control are provided with film outlet pipeline Make water start and stop, pressure gauge measure mould it is poor.Show fouling membrane when pressure differential rise is excessive, Chemical cleaning need to be carried out.Film Cleaning chemicals dosing plant is positioned over above membrane cisterna, and alkali cleaning uses 1% oxalic acid, dosing pipeline and film using 0.5% sodium hypochlorite, pickling Component water producing pipe connects, and closes film water solenoid valve during cleaning, and dosing valve is opened, and medicament is infiltrated into film group by gravity stream Inside part, 2-3 hours i.e. completion on-line cleaning is stopped, reopens outlet valve production water., can if chance water quality situation is poor Carried out disinfection processing in adding sodium hypochlorite in middle pond, because Membrane cleaning medicament also uses sodium hypochlorite medicament, medicine-chest can be shared. Excess sludge in membrane bioreactor is pumped in storage basin by the sludge pipe at membrane cisterna bottom through screw rod, storage basin and reclaimed water Build together in pond.
Whole integrated equipment for sewage treatment controls grid, immersible pump, stirring respectively using the integrated control of PLC self-control cabinets Whole electrical equipments, instrument and the valves such as machine, air blower, self priming pump, fluid level controller, Membrane cleaning medicine-chest, magnetic valve, it is completely real Present line automation control.Only it is found when membrane module need to clean or occur membrane component damage offline, personnel need to be arranged to now Handled, remaining operation stage can accomplish unattended, greatly reduce management cost.
This unattended sanitary sewage disposal and reusing integral equipment and technological process are above described, can be according to reality Demand Design goes out the container-type complete set of equipments of the different disposal scale such as 50t/d, 100t/d, 200t/d, and the complexes are overall Material uses carbon steel polyurea anti-corrosion, and inside is separated into compartment of different sizes according to different process unit, and water inlet passes sequentially through phase Even compartment carries out the processing of corresponding process section.The integrated MBR films composite bioreactor has that disposal ability is strong, separation of solid and liquid The advantages of efficiency high, space are small, effluent quality is good.
