Description

Sewage pre-treatment integrated apparatus
Technical field
This device is related to small-scale water process integrated treatment unit technical field, the more particularly to water in rural area township, town, village The early stage of process is processed.Process suitable for scattered villages and small towns and urban cells dirt resident living area sewage early stage.
Background technology
According to statistics, national villages and small towns produce sanitary sewage every year hundred million tons about more than 80, wherein 96% village does not have discharge conduit And sewage disposal system.Sanitary sewage is discharged wantonly, the severe contamination ecological environment in rural area, directly threatens the vast farmerses masses Healthy and rural area economic development.The tap water popularity rate in whole nation rural area only has 34% or so, also more than 300,000,000 at present There is safe drinking water in peasant.The unprocessed direct discharge of the low situation of water head site water quality and domestic sewage in rural areas have it is direct because Fruit relation.
Sewage disposal pattern in villages and small towns mainly has three kinds:(1) include urban drainage pipe network:The mainly agriculture of cities and towns suburb nearby Village.(2) villages and small towns focus on pattern:Will the sewage centralized collection that produces of all resident families, it is unified to build sewage treatment plant.(2) Decentralized processing pattern, will sewage subregion collect, individual processing, generally using middle-size and small-size sewage disposal device.
For can not unify to build sewage treatment plant or be incorporated to the dispersion villages and small towns of urban pipe network, suitably using small-scale sewage at Reason equipment is realizing villages and small towns decentralized wastewater treatment.Sanitary sewage discharges the features such as time difference is big, and the water yield is concentrated, debris are more in water, is Guarantee sewage later stage process it is normal run, have to configure grid, setting pot, tune before each integrated sewage treating apparatus Section pond.The small-sized process dress of early stage sewage of this patent designed by small rural sewage-treatment plant is filled with later stage sewage disposal Put and support the use.
Utility model content
According to the characteristics of rural area villages and small towns and residence district, sewage disposal device needs miniaturization to designer of the present utility model Grid interception, sand setting and regulating reservoir are combined together by generalization through research design, change the operation side of traditional three units Formula, the design fully take into account rural area management and economic condition many factors, as far as possible convenient using maintenance management simple to operate The design concept of small investment.Conventional grates are changed to the design of grid hand basket in the design of this device, and manual operation does not have machinery to set It is standby, need not safeguard in running.Setting pot flows sand setting mode using aeration eddy flow is perpendicular in the design, using flow rotation Sand fallout is accelerated in effect, and sediment outflow adopts gravity sediment outflow mode, do not set any plant equipment, need not tie up in running Shield.Regulating reservoir designs immersible pump by sewage lifting to sewage-treatment plant in the design in regulating reservoir, is provided with plug-flow stirring Device, the design regulating reservoir can be used with simultaneous anaerobic pond.Immersible pump needs control conveying sewage quantity according to system using VFC. Pushing flow mixer work during anaerobism causes pool inner water vortex rotation, accelerates anaerobe to be fully contacted with water, it is ensured that effluent quality.It is logical The characteristics of crossing investigation villages and small towns sewage and its existing problems, this patent is in easy to operate, saving operating cost and management service expense The purpose of preliminary treatment is issued to etc. condition.On this basis, develop a kind of primary treatment device of high efficiency low energy consumption and Method-sewage pre-treatment integrated apparatus.
Sewage pretreating device technique described in this utility model, it is characterised in that:Technique is flexibly reliable and stable, after being Continuous advanced treating provides safety, continuous, stable, guarantee.By the culture of anaerobe, using the effect of anaerobe, Organic substance is made Generation hydrolysis, acidifying and methanation, remove the Organic substance in waste water, and improve the biodegradability of sewage, and it is follow-up good to be conducive to Oxygen is carried out a biological disposal upon, and sewage pre-treatment integrated apparatus have easy transportation and installation quick, and short construction period can be according to different fields The characteristics of ground situation combination in any, low investment cost.
Sewage pre-treatment integrated apparatus, the device include that grid hand basket 1, sediment by rotational flow pipe 2, sand-catching apparatus 3, compression are empty Trachea 4, sanitary sewage import 5, impeller 6, sediment outflow pipe outlet 7, diving elevator pump 8, pretreated water outlet 9, balancing tank 10; Subject of implementation structure of the balancing tank 10 for the sewage pre-treatment integrated apparatus, sanitary sewage import 5 are passed through with grid hand basket 1 Pipeline connects, and grid hand basket 1 is arranged on the top of sediment by rotational flow pipe 2, and 5 Jing grid hand basket 1 of sanitary sewage import enters the sand setting that becomes a mandarin In pipe 2, stream sand sediment pipe 2 is arranged vertically in sand-catching apparatus 3, is provided with rotating flow between stream sand sediment pipe 2 and sand-catching apparatus 3 Space.
One end of compressed air hose 4 is connected with the top of stream sand sediment pipe 2, and compressed air hose 4 pairs is laggard through grid hand basket 1 The sewage become a mandarin in sand sediment pipe 2 is purged;Sewage after rotating flow purification is entered by the spout hole at the top of sand-catching apparatus 3 Enter balancing tank 10;Sewage contamination precipitation after rotating flow purification is in the bottom of sand-catching apparatus 3, and 3 bottom of Jing sand-catching apparatus The sediment outflow pipe outlet 7 in portion is discharged.
Impeller 6 is arranged on the side of balancing tank 10, and diving elevator pump 8 is arranged on the bottom in balancing tank 10, dives Water elevator pump 8 is connected with pretreated water outlet 9.
The grid hand basket 1 is that Manual mechanical adjusts hand basket.
Anaerobe is added with the balancing tank 10.
This device is carbon steel or stainless steel structure.
The operation principle and process of this device is as follows.
(1) grid hand basket processing stage sewage is directly entered the first of this device after anaerobic tank, by grid hand basket every Leave away except big granule debris.
(2) sewage after the filtration of grid hand basket enters the perpendicular stream settling system of aeration, and sewage is subject in perpendicular stream sand sediment pipe Compressed air hose air-out is purged, and sewage produces rotating flow motion in stream sand sediment pipe, and collision friction is produced between sand grains, will The Organic substance for being wrapped in sand surface is removed, and produces clean sand setting, improves the clearance of sand, under the influence of centrifugal force compared with The sand grains of weight is fallen in the sand deposition hopper of bottom, and water and lighter Organic substance rotate to outer, by subsequently water inlet plug-flow to overflow launder, Jing Anaerobism regulating reservoir is flowed into after spout hole.Silt particle is discharged by discharge pipeline after the standard of presetting blowdown is reached after precipitation.
