Abstract

The invention relates to a piece of novel household sewage treatment equipment which is characterized by comprising a water inlet valve 1, a separation net 2, a clapboard 3, a blowoff valve 4, an exhaust valve 5, a filter layer 6, an air pump 7, a hollow fiber ultrafiltration membrane component 8, a membrane bioreactor 9, an air guide pipe 10, a water guide pipe 11, a water pump 12, a water level gauge 13, a water storage tank shell 14, an ultraviolet disinfection lamp 15, a water outlet valve 16, a sponge layer 17, a modified coal cinder layer 18, a quartz sand layer 19 and an active carbon layer 20. The household sewage treatment equipment uses the membrane bioreactor to treat sewage, pollutants are degraded in the membrane bioreactor to remove most of CODCr, BOD5, turbidity, NH3-N, total phosphorus and the like after passing through a filter (I) and a membrane bioreaction tank (II), and then the sewage is disinfected by the ultraviolet disinfection lamp so as to be stored in a recycled water reuse tank (III) to be used as household reuse water.

Description

The domestic sewage treatment facility

Technical field

The present invention relates to a kind of sewage disposal device, especially refer to a kind of Membrane Bioreactor for Wastewater Treatment domestic sewage equipment that utilizes.

Background technology

In " State Council is about printing and distributing the notice of the comprehensive programme of work of energy-saving and emission-reduction ", clearly proposed to improve energetically the reuse degree of domestic sewage.The domestic sewage reuse is exactly the basic skills that development is come out from resident living.In the daily life, the consciousness of saving water of town dweller's water also is not very strong, and sewage directly flows into sewer line through sewer line usually, causes most of water all just not make full use of and is flushed away, and makes that the water loss in the family is bigger.If can water cycle wherein be used; Picture water consumption in the family life bigger wash dish, sewage collecting such as do washing, have a bath, wash one's face and rinse one's mouth; Adopt " filtration+gac+membrane bioreactor+sterilization " but art breading obtain the middle water of reuse; Be used to flush the toilet, water, cleaning, carwash etc. be to the less demanding occasion of water degree of cleaning, makes the sewage second stage employ.Problems such as the domestic sewage treatment facility generally has operation complicated at present, and the sewage purification rate is not high, and floor space is big, this equipment, not only easy and simple to handle, and can make full use of water resources, and effectively use and take up an area of, reduce the water consumption of family, alleviate the shortage of water resources problem.

Summary of the invention

To the problems referred to above; The present invention adopts membrane bioreactor that sewage is handled; The main technique flow process is for to get up to pour into header tank with the sewage collecting of washing dish in the family, doing washing, have a bath, wash one's face and rinse one's mouth; Water is pumped into sewage disposal device, through filtering basin, membrane biological reaction pond, removes the most COD in the sewage after making the biological degradation of pollutent mikrobe in membrane bioreactor in the sewage _Cr, BOD ₅, turbidity, NH ₃Pollutent such as-N, total phosphorus, with sewage water reuse tank from the suction of membrane biological reaction pond, water reuse tank in behind the uv lamp sterilization and disinfection, being stored in is used for family's reuse water under the water pump suction function.Following in order to realize the technical scheme that the object of the invention adopts:

Described domestic sewage treatment facility is consisted of by filtering basin (I), membrane biological reaction pond (II), middle water reuse tank (III) three parts.

Described filtering layer (6) is made up of spongy layer (17), modified coal slag layer (18), quartz sand layer (19), active carbon layer (20).Wherein spongy layer (17) absorbs the sewage with oil material; Modified coal slag layer (18) is removed materials such as sewage N, P; Quartz sand layer (19) filters sewage fine; Active carbon layer (20) is removed BOD in the sewage on a small quantity ₅, material such as CODcr.

Described membrane bioreactor (9) is the novel waste water technology that membrane separation technique and biotechnology organically combine, and also claims the film separated activated sludge method.Utilize membrane separation plant that active sludge and larger molecular organics matter are held back, under the absorption of aerobe, Degradation, sewage is carried out Depth Filtration.Make the biochemical reaction of sewage carry out more thoroughly more rapidly, guaranteed that water outlet is limpid.

Described ultraviolet disinfecting (15) carries out sterilization to sewage.

This designs a model sewage collecting such as wash dish in the family, do washing, have a bath, wash one's face and rinse one's mouth, adopt " filtration+gac+membrane bioreactor+sterilization " but art breading obtain the middle water of reuse, can effectively reduce COD _Cr, BOD ₅, turbidity, NH ₃Contamination index such as-N, total phosphorus, treatment effect is high, good purification; Also use three-dimensional arrangement, so floor space is little; Only need to pour sewage into header tank during use and just can obtain reuse water, uses simple to operationly, processing cost is low, and treatment effect is good, and water cycle is used, and is adapted at small-sized places such as family, and is more obvious to the regional effect of lack of water, and it is easy to popularize ten minutes.Believe and have application prospect well in future.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the present invention is further specified
