Abstract

Disclosed is an integrated membrane biological sewage treatment unit, which relates to a sewage treatment unit. The integrated membrane biological sewage treatment unit includes an upright tank body, one end of the upper portion of the tank body is provided with a water inlet while the other end of the upper portion is provided with a water outlet, the water inlet side of the bottom of the tank body is provided with a blowdown port, an anaerobic zone and an aerobic zone are positioned in the tank body, and a filter membrane intercepting the cross section of the tank body is disposed between the aerobic zone and the water outlet. The integrated membrane biological sewage treatment unit is simple in structure, small in occupied area, low in energy consumption and fine in treatment effect, realizes respective controlling of hydraulic retention time and sludge retention time due to highly efficient interception of the membrane, and substances unable to pass through the membrane is retained in the tank body to be degraded by active sludge, thereby increasing biochemical effect while allow operation of the system to be controlled flexibly and stably, further saving operational cost, reducing secondary pollution, enhancing impact load resistance, stabilizing water quality, prolonging sludge discharging period, easily realizing automatic control, simplifying operation and facilitating maintenance, and therefore, the integrated membrane biological sewage treatment unit can be used as an environmental protection unit for domestic sewage treatment.

Description

The integrated film biology sewage treatment equipment
Technical field
The utility model relates to a kind of waste disposal plant, particularly a kind of waste disposal plant that reclaimed water is carried out reuse.
Background technology
A kind of integrated sewage treating apparatus is arranged in the prior art, primary structure comprises the pond body of upright setting, the bottom of pond body is provided with water-in, and body top, pond is provided with water outlet, and device mainly is made of preliminary sedimentation tank, contact-oxidation pool, second pond, sterilization pool and sludge sump.The carrier of elastic solid filler as microorganism growth is set in the described contact-oxidation pool, and aerating system adopts micro-hole aerator in the pond.During work, sewage is in the water-in access to plant, and the post precipitation sewage of process preliminary sedimentation tank enters contact-oxidation pool, and the aerobic microbiological in the contact-oxidation pool is discharged from water outlet through sewage behind second pond and the sterilization pool the organism biodegrade of sewage again.When adopting this method to dispose of sewage, organism treatment effect to difficult degradation is relatively poor, to the ammonia-N removal rate DeGrain, equipment is provided with preliminary sedimentation tank and second pond, occupation area of equipment is bigger, handle back water outlet solid suspension substrate concentration about 30mg/L, the standard (the solid suspension substrate concentration is 10mg/L) of water reuse in can not reaching.
The utility model content
For solving the above problems, the utility model provides a kind of filtering membrane of setting up in reaction tank, organism, difficult degradation thing are trapped within the reaction zone integrated film biology sewage treatment equipment that hydraulic detention time (HRT) and sludge retention time (STR) can be controlled respectively.
The technical solution of the utility model is: the pond body that comprises upright setting, one end on the top of pond body is provided with water-in, the top the other end is provided with water outlet, pond body bottom water inlet oral-lateral is established evacuation port, Chi Tizhong is provided with anoxic section, aerobic section, is provided with the filtering membrane of interception pond body section between aerobic section and the water outlet.
Be provided with aeration tube in bottom, aerobic section pond.
Described filtering membrane adopts polypropylene diaphragm, and the diaphragm upper and lower end connects support tubes, and the support tubes two ends are connected with the pond body respectively.
The utility model membrane module can be trapped in active sludge macromole and bacterium in the body of pond.Because filtration, the efficiently effect of damming of film, realized that hydraulic detention time (HRT) and sludge retention time (STR) can control respectively, organism, difficult degradation thing are trapped within the reaction zone, and the metabolism by microorganisms such as autotrophic bacteria and heterotrophic bacteriums obtains degraded.Water reuse standard during sewage can reach through the every index of water outlet behind the membrane filtration.And equipment is more simplified, and has cancelled preliminary sedimentation tank and second pond.Floor space significantly reduces, and investment cost and running cost are lower.
The utility model is simple in structure, floor space is little, energy consumption is low; Treatment effect is good, because the efficient crown_interception of film, realized that hydraulic detention time and sludge retention time can control respectively, can not be trapped in the body of pond by the diaphragm-operated material, degraded by active sludge, when improving biochemical effect, make the operation control of system stable flexibly; And saving running cost, secondary pollution is little, and anti-load impact ability is strong, stable effluent quality, sludge discharging period is long, easily realizes control automatically, and is simple to operate, easy to maintenance.The environmental protection equipment that can be used as sanitary sewage disposal uses.

Embodiment
As shown in Figure 1, 2, the utility model comprises the pond body 2 of upright setting, one end on the top of pond body 2 is provided with water-in 1, the top the other end is provided with water outlet 4, pond body 2 bottoms water inlet oral-lateral is established evacuation port 3, be provided with anoxic section 9, aerobic section 7 in the pond body 2, be provided with the filtering membrane 8 in interception body 2 cross sections, pond between aerobic section 7 and the water outlet 4.
Be provided with aeration tube 6 in bottom, aerobic section 7 ponds.Bottom, anoxic section 9 ponds also is provided with aeration tube 6.Aeration tube 6 is by the gas blower air feed.
Filtering membrane 8 adopts polypropylene diaphragm, and the diaphragm upper and lower end connects support tubes, and the support tubes two ends are connected with pond body 2 respectively.
The utility model is in when work, and sewage enters in the pond body 2 from water-in 1, and at first big suspended substance is tackled in 5 pairs of sewage of grid, thereby improves the treatment effect of subsequent treatment process, and then sewage enters anoxic section 9 and carries out the denitrification of ammonia nitrogen; Enter aerobic section 7 afterwards, the aerobic activated sludge in the aerobic section 7, carries out ammonia nitrogen simultaneously and carries out nitrification the organism biodegrade in the sewage by the air that discharges in the aeration tube 6, and ammonia nitrogen is had higher removal.Then sewage filtration by film 8 assemblies in holding back the district is finally discharged by water outlet 4.Effluent quality can reach middle water reuse standard.A mud part that produces in the body of pond is back to aerobic section 7, and another part discharges outside the pond 2.Utilize the aerating apparatus hold back in the district 6 that it is cleaned during to film 8 assembly backwashes, thereby guarantee the treatment effect of film 8 assemblies.
Diaphragm material in film 8 assemblies is a polypropylene, and the membrane module physical strength is good, stable chemical performance, and oxidation-resistance is strong, can adopt strong acid and strong base to clean, and is very suitable for sewage disposal.When reality is used, can carry out the scouring of fullest to the film surface with the aerating system in the biochemistry pool, alleviate the pollution on film surface, keep stable water production rate.The permeable amount of this adventitia is big, by various combination, can be applicable to large-scale sewage treatment project.
