Abstract
The utility model relates to the technical field of sewage treatment equipment, in particular to urban sewage treatment equipment which comprises a sedimentation tank and a sewage treater main body; the sewage treater main body is arranged at the bottom of the sedimentation tank; a primary filter screen is arranged between the sewage treater main body and the sedimentation tank; four stages filters are arranged inside the sewage treater main body in sequence from top to bottom, wherein the tops of every two adjacent stages of filters are provided with a mutually communicated pipeline; the first stage of filter in the four stages of filters is a sand filter cylinder filter; the second stage of filter is an active carbon fixing bed adsorption filter; the third stage of filter is a positive ion resin exchange filter; the four stage of filter is a ozone sterilizing filter; and the top of the ozone sterilizing filter is provided with an external discharge pipe. As the uppermost of the urban sewage treatment equipment is the sedimentation tank; sewages are convenient to collect; simultaneously, the four stages of filter are used for treating the urban sewage; the urban sewage treating equipment has a vertically-arranged structure; the floor area is reduced; and the construction cost is reduced.
Description
Technical field
The utility model relates to technical field of sewage treatment equipment, relates in particular to a kind of urban wastewater treatment equipment.
Background technology
At present; For municipal sewage treatment; Traditional treatment process is to be divided into three grades, and the first step is pre-treatment, and technology commonly used has equalizing tank, grid and first dirt pond etc.; Mainly be the balanced water yield, water quality and remove macrobead swimmer and sand setting in the water, with the load that reduces subsequent technique and reduce detrimentally affect follow-up equipment; The second stage is treated to biological process, and activated sludge process commonly used, main purpose are to remove organism in the water, and strengthening second-stage treatment mainly is denitrogenation dephosphorizing, reduces the risk of receiving water body eutrophication; The third stage is handled or advanced treatment is to be the processing of target with the treating water reuse, removes tiny particle in water material, free bacteria, virus and further reduces COD, uses physico-chemical process usually, and traditional technology is flocculation+deposition+filtration+sterilization.Usually, urban wastewater treatment equipment all is that planar design has settling tank, horizontal flow basin, filtration unit, biological tank etc. now, and the sewage of discharging is waited the whole process of accomplishing WWT through settling tank, horizontal flow basin, filtration unit, concentration basin, device for separating mud and water; Wherein settling tank is with sewage natural sedimentation in the pond, makes the deposition of dirt bottom in the pond in the sewage, thereby is convenient to collect; But adopt this processing unit; Each treating pond is the plane tiled arrangements, and floor space is big, and construction cost is high; Being difficult to adopt this method to carry out blowdown for general medium and small building handles, has certain limitation.
Summary of the invention
The utility model technical problem to be solved is through present sewage disposal device being arranged again, occupation area of equipment is reduced, reducing construction cost.
For solving the problems of the technologies described above; The technical scheme of the utility model. a kind of sewage disposal device is characterized in that: comprise settling tank and apparatus for treating sewage body; Said apparatus for treating sewage body is arranged on the settling tank bottom, is provided with preliminary filtering net between apparatus for treating sewage body and the settling tank bottom; The apparatus for treating sewage body interior is disposed with the level Four strainer from top to bottom; Wherein, the top of every adjacent two-stage filter is provided with the pipeline of mutual perforation, and first step strainer is a sand filtration tube strainer in the said level Four strainer; Said second stage strainer is the activated carbon and fixed bed adsorption filter; Said tertiary filter is the resin cation exchange strainer, and said fourth stage strainer is the ozonization strainer, and the top of said ozonization strainer is provided with outer comb.
The present technique scheme is at first passed through settling tank with the bottom of the deposition of dirt in the sewage in the pond; Have again upward and down through preliminary filtering net, sand filtration tube strainer through oettIed sewage then; Activated carbon and fixed bed adsorption filter, resin cation exchange strainer, ozonization strainer are discharged through outer comb at last.Like this, owing to be settling tank topmost, dirt is convenient to collect; Simultaneously; The level Four strainer is accomplished effects such as pre-treatment, biological process processing, treating water reuse respectively, has played the purpose of Treating Municipal Sewage, in addition because the level Four strainer is upper and lower arrangement architecture; Floor space reduces, and has reduced construction cost.Particularly in areas, mountain area such as Chongqing; Reason owing to physical features; When each treating pond is the plane tiled arrangements, be prone to cause the treating pond of back high and cause the abnormal phenomenon of WWT, adopt so upper and lower structure arranged can avoid above-mentioned abnormal phenomenon than the front.
Further; An end that is limited to the settling tank described in the above-mentioned technical scheme is provided with a plurality of sewage imports, and described water treating device body is arranged on the sewage entrance end away from described settling tank, limits the relative position of water treating device body and settling tank; Be under identical working conditions; Can make the settling tank better utilised, reduce the WP of back strainer, improve the processing power of sewage.
Description of drawings
Fig. 1 is the structural representation of a kind of urban wastewater treatment equipment of the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the technical scheme of the utility model is further specified:
As shown in Figure 1; The utility model technical scheme; A kind of sewage disposal device comprises settling tank 1 and apparatus for treating sewage body 2, and an end of described settling tank 1 is provided with three sewage imports 11; Described water treating device body 2 is arranged on the bottom away from sewage import 11 ends of described settling tank 1, is provided with preliminary filtering net 3 between apparatus for treating sewage body 2 and settling tank 1 bottom; Apparatus for treating sewage body 2 inside are disposed with the level Four strainer from top to bottom; Wherein, the top of every adjacent two-stage filter is provided with the pipeline 20 of mutual perforation, and first step strainer is a sand filtration tube strainer 21 in the said level Four strainer; Said second stage strainer is an activated carbon and fixed bed adsorption filter 22; Said tertiary filter is a resin cation exchange strainer 23, and said fourth stage strainer is an ozonization strainer 24, and the top of said ozonization strainer is provided with outer comb 4.
Above-described only is the preferred implementation of the utility model; Should be understood that; For a person skilled in the art, under the prerequisite that does not break away from the utility model structure, can also make some distortion and improvement; These also should be regarded as the protection domain of the utility model, and these can not influence effect and practical applicability that the utility model is implemented.
