Abstract
The utility model discloses a sewage treatment system. The sewage treatment system is connected with a sewage tank by virtue of a first filtering unit, a coal slag filter is arranged in the first filtering unit, the first filtering unit is communicated with one sedimentation tank, the sedimentation tank is communicated with a second filtering unit, a second activated carbon filter is arranged at the upper half part of the second filtering unit, the lower half part of the second filtering unit is connected with a third filtering unit, the third filtering unit is provided with a third activated carbon filter, the third activated carbon filter is fixedly arranged on the third filtering unit, and the third filtering unit is connected with the sewage tank by virtue of the third activated carbon filter. Coal slag in the coal slag filter of the first filtering unit has the characteristics of large surface area, strong adsorption force, good water permeability and low cost and is simple and practicable when being used as an adsorption material, adsorption effect is good, COD (chemical oxygen demand) value is reduced to 400 from 500, and then the COD value is reduced to be less than 200 through filtration by virtue of the sedimentation tank, the second filtering unit and the third filtering unit.
Description
Technical field
The utility model relates to a kind of Sewage treatment systems, belongs to the technical field of sewage multi-stage processing equipment.
Background technology
The method of processing now industrial sewage is that sewage is drawn toward water collecting basin, water collecting basin is regulated to pH value, rise to first class pressure dissolving with one-level dissolved air water pump, air amount and coacervation discoloring agent simultaneously, one-level saturated dissolved gas water in first class pressure dissolving is discharged into one-level air flotation pool suddenly and forms coagulation water, sewage lagoon process need regulates pH value, complex process, energy consumption is high, can not meet people's requirement.
Utility model content
The purpose of this utility model is to provide a kind of Sewage treatment systems, solves the shortcoming that prior art exists.
The utility model adopts following technical scheme to realize:
A kind of Sewage treatment systems, it is characterized in that, described Sewage treatment systems is connected with sewage lagoon by the first filtering unit, in described the first filtering unit, be provided with cinder filtration device, the first filtering unit is connected with a settling tank, described settling tank is connected with the second filtering unit, upper part of described the second filtering unit is provided with the second activated charcoal filter, lower part of the second filtering unit is connected with the 3rd filtering unit, upper part of described the 3rd filtering unit is provided with the 3rd activated charcoal filter, described the 3rd activated charcoal filter is fixedly mounted on upper part of the 3rd filtering unit, the 3rd filtering unit is connected with a sewage lagoon by the 3rd activated charcoal filter, on described sewage lagoon, be provided with water shoot.
Further, between described settling tank and the second filtering unit, be provided with water pump.
Further, be provided with the settling bath of a U font on described settling tank, described settling bath one end is fixedly connected on the opening part inwall of settling tank, and the other end is fixed with a catch by screw, and the bottom of described settling bath is provided with posticum.
Further, the upper end of described catch has deep-slotted chip breaker.
Useful technique effect of the present utility model is: the features such as the cinder in the cinder filtration device in the first filtering unit has that surface-area is large, adsorptive power is strong and good water permeability, cost be low, simple as sorbing material, adsorption effect is fine, COD value (chemical oxygen demand (COD)) drops to 400 from 500, pass through the filtration of settling tank and second and third filtering unit, COD value (chemical oxygen demand (COD)) has been down to below 200 again.
Brief description of the drawings
Fig. 1 is one-piece construction schematic diagram in the utility model Sewage treatment systems.
Fig. 2 is the overflow device structural representation of settling tank.
Embodiment
By the description to embodiment below; to more contribute to public understanding the utility model; but specific embodiment given applicant can't be considered as to the restriction to technical solutions of the utility model, any definition to parts or technical characterictic change and/or to one-piece construction do form and immaterial conversion all should be considered as the protection domain that the technical solution of the utility model limits.
A kind of Sewage treatment systems, Sewage treatment systems is connected with sewage lagoon 1 by the first filtering unit 2, in the first filtering unit 2, be provided with cinder filtration device, can a dividing plate be set the first filtering unit 2 is interior, the first filtering unit 2 is separated into two spaces, in the space being communicated with sewage lagoon 1, fill cinder to form cinder filtration device, sewage is the filtration through cinder filtration device at the first filtering unit 2, and the first filtering unit 2 is connected with a settling tank 3.In this stage owing to only having passed through the filtration of the first filtering unit 2, impurity in sewage is still more, so can make further improvement to settling tank 3, to allow the sedimentation and filtration better effects if of settling tank 3, can on settling tank 3, be provided with the settling bath of a U font, settling bath one end is inboardend 9, settling bath is fixedly connected on the opening part inwall of settling tank by this inboardend 9, the other end is fixed with a catch 10 by screw 12, the bottom of described settling bath is provided with posticum 11, and the upper end of catch has deep-slotted chip breaker.Pending sewage enters in settling tank 3 from water-in, the spots such as floating matter are all blocked in outside settling bath, and water can enter in settling bath from the deep-slotted chip breaker of catch 10 at leisure, and flow out from posticum 11, the height that can regulate according to the situation of different quality settling bath by changing the position of screw 12, effectively prevents because of the different filter effects that affect sewage of local flow.Settling tank 3 is connected with the second filtering unit 5, between settling tank 3 and the second filtering unit 5, a water pump 4 is set, upper part of the second filtering unit 5 is the second activated charcoal filter, a dividing plate 6 can be set the second filtering unit 5 is divided into two spaces, wherein upper part is filled with gac to form active carbon layer, lower part of the second filtering unit 5 is connected with the 3rd filtering unit 5, upper part of the 3rd filtering unit 6 is provided with the 3rd activated charcoal filter, the 3rd activated charcoal filter is fixedly mounted on upper part of the 3rd filtering unit 6, the 3rd filtering unit 6 is connected with a sewage lagoon 7 by the 3rd activated charcoal filter, on sewage lagoon 7, be provided with water shoot 8, it is large that cinder in cinder filtration device in the first filtering unit 2 has surface-area, strong and the good water permeability of adsorptive power, the features such as cost is low, simple as sorbing material, adsorption effect is fine, COD value (chemical oxygen demand (COD)) drops to 400 from 500, pass through again settling tank 3 and second, the filtration of three filtering units, COD value (chemical oxygen demand (COD)) has been down to below 200.
Certainly; the utility model can also have other various embodiments; in the situation that not deviating from the utility model spirit and essence thereof; those of ordinary skill in the art can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the utility model.
