Description
Technical field
The utility model relates to sewage treatment area, adds baffled MBR sewage treatment experimental device more specifically to a kind of.
Background technology
In sewage treatment process, building a sewage work need to invest very large, main is that soil is expensive on the one hand, build on the other hand various reaction tank expenses high, how effectively reducing the floor space of sewage work and not affecting sewage disposal result is the problem of studying at present, immobilized active mud method is receiving much attention at present, immobilized microorganism buttress is different with the dissolved oxygen concentration in water according to its thickness, outer microtube biology at immobilized microorganism plate carries out aerobic respiration, middle layer microorganism is because the oxygen concentration lower entering is in anaerobic respiration, the microorganism of innermost layer is because oxygen content is extremely low often in anaerobic respiration, at present a lot of research units can research institutions all study aspect immobilized microorganism, but a lot of laboratories lack complete experimental installation.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art.For achieving the above object, the utility model has adopted following technical scheme:
A kind ofly add baffled MBR sewage treatment experimental device, comprise pump sump, activated sludge tank, clean water basin, membrane module, electronic grout flow meter, immobilized active mud plate, water pump, oxygenerator, hydraulic inductor, also comprise programmable logic controller, described pump sump, activated sludge tank, clean water basin connect successively by pipeline, baffle plate is set in the middle of described activated sludge tank, immobilized active mud plate is installed between baffle plate and feed-water end, between baffle plate and water side, membrane module is installed, backwashing pump is installed in described clean water basin, backwashing pump rising pipe is connected with membrane module, one group of aeration tube is installed in described activated sludge tank bottom under immobilized active mud plate, aeration tube is connected with oxygenerator, electronic grout flow meter is installed on aeration tube, described programmable logic controller and water pump, backwashing pump, oxygenerator electrical connection.
Described immobilized active mud plate is fixed the active sludge of 3.5cm thickness by immobilized solvent, when immobilized sludge plate is installed, two sides parallel with water (flow) direction, and top height is lower than water outlet height.
One hydraulic inductor is installed in described activated sludge tank, and is electrically connected with programmable logic controller.
The described low 10-20cm of baffle plate specific activity sludge sump pool wall height.
The utlity model has following advantage: experimental installation cost is low, intelligent, convenient transportation, take up room little.
Brief description of the drawings
Fig. 1 is experimental installation schematic diagram of the present utility model.
Wherein, 1, pump sump; 2, water pump; 3, activated sludge tank; 4, immobilized active mud plate; 5, aeration tube; 6, baffle plate; 7, membrane module; 8, oxygenerator; 9, electronic grout flow meter; 10, clean water basin; 11, backwashing pump; 12, programmable logic controller.
Embodiment
With the drawings and specific embodiments, the utility model is described in further detail below.
As shown in the figure,
A kind ofly add baffled MBR sewage treatment experimental device, comprise pump sump 1, activated sludge tank 3, clean water basin 10, membrane module 7, electronic grout flow meter 9, immobilized active mud plate 4, water pump 2, oxygenerator 8, hydraulic inductor, also comprise programmable logic controller 12, described pump sump 1, activated sludge tank 3, clean water basin 10 connect successively by pipeline, in the middle of described activated sludge tank 3, baffle plate 6 is set, immobilized active mud plate 4 is installed between baffle plate 6 and feed-water end, between gear 6 plates and water side, membrane module 7 is installed, the interior installation backwashing pump 11 of described clean water basin 10, backwashing pump 11 rising pipes are connected with membrane module 7, one group of aeration tube 5 is installed 4 times at immobilized active mud plate in described activated sludge tank 3 bottoms, aeration tube 5 is connected with oxygenerator 8, electronic grout flow meter 9 is installed on aeration tube 5, described programmable logic controller 12 and water pump 2, backwashing pump 11, oxygenerator 8 is electrically connected.
Described immobilized active mud plate 4 is fixed the active sludge of 3.5cm thickness by immobilized solvent, when immobilized sludge plate 4 is installed, two sides parallel with water (flow) direction, and top height is lower than water outlet height.
Interior installation one hydraulic inductor of described activated sludge tank 3, and be electrically connected with programmable logic controller 12.
The described low 10-20cm of baffle plate 6 specific activity sludge sump pool wall height.
After the utility model comes into operation, sewage passes into activated sludge tank from pump sump and is drawn to clean water basin by water pump by membrane filtration, sewage in activated sludge tank with immobilized active mud plate joint, the outer field microorganism of immobilized active mud plate carries out aerobic respiration and consumes organism and part inorganics under the higher environment of dissolved oxygen concentration, at immobilized microorganism inner cord because dissolved oxygen concentration is more and more lower, internal layer microorganism carries out anoxic denitrification denitrogenation, the too low microorganism of oxygen concn of innermost layer often carries out anaerobism dephosphorization, water after treatment passes through biofilm filtration, after filtering, use water pump to aspirate in water suction clean water basin after treatment.Baffle plate is set in activated sludge tank can be reduced suspended sludge and contact with microbial film, thereby reducing film pollutes, therefore only need before baffle plate, under immobilized active mud plate, aeration tube be set carries out pure oxygen aeration, and the backwashing pump in clean water basin utilizes water timing after treatment to carry out back flushing.
