Description

The integrated treatment unit of suspended substance in sewage
Technical field
The utility model belongs to treatment unit, is specifically related to the integrated treatment unit of suspended substance in a kind of sewage.
Background technology
In sewage treatment process, for some trade effluent, the suspension content in water is higher, the content of COD, BOD5 is not high, in this case, main processes is exactly the SS that will remove in water, if adopt air floatation machine and hay tank just may can reach good treatment effect.At this moment need after air floatation machine, add filtration unit, as gac, quartz sand or multi-medium filtering.Need to pressurize after sewage leaves air floatation machine, enter hay tank, in traditional technological process, first will add the design in a heavy pond after air floatation machine, with pump, water be squeezed into pressure filter tank afterwards, floor space is large, and cost of investment is high.
Summary of the invention
In order to overcome the problems referred to above that prior art field exists, the purpose of this utility model is, the integrated treatment unit of suspended substance in a kind of sewage is provided, solve the design that traditional sewage disposal needs to add a heavy pond after air floatation machine, with pump, water is squeezed into pressure filter tank afterwards, floor space is large, the problem that cost of investment is high.
The integrated treatment unit of suspended substance in the sewage that the utility model provides, it comprises air floatation machine, filter tank, clean water basin, back-purge system, described air floatation machine is arranged at front end, the bottom of air floatation machine is provided with air floatation machine water outlet, the filter tank that described inside is filled with filtration medium is fixedly installed on below air floatation machine, filter tank is connected with air floatation machine by air floatation machine water outlet, the end in filter tank is provided with filter tank water outlet, described filter tank water outlet is connected with clean water basin by outlet conduit, and be connected with back-purge system bottom filter tank, the end of described clean water basin is provided with water port.
Described back-purge system comprises Backwash pipeline, backwashing pump, described Backwash pipeline one end and clean water basin, and the other end is connected to bottom filter tank, and described backwashing pump is arranged in Backwash pipeline, coordinates with Backwash pipeline.
This treatment unit entirety can adopt the anticorrosion or stainless material of carbon steel, and filtration medium can adopt quartz sand, gac or multimedium combination.
The integrated treatment unit of suspended substance in the sewage that the utility model provides, its beneficial effect is, air floatation machine and filtration unit combine by this device, without the need to pressurization, do not need to arrange settling tank, reduce floor space and cost of investment simultaneously, change filtration medium convenient, suspended substance in the disposable removal water of energy, reaches the requirement that water outlet is limpid.
Accompanying drawing explanation
Fig. 1 is the one-piece construction schematic diagram of the utility model embodiment.
Mark in figure:
1. air floatation machine; 2. air floatation machine water outlet; 3. filter tank; 4. filtration medium; 5. filter tank water outlet; 6. clean water basin; 7. backwashing pump; 8. Backwash pipeline; 9. water port.
Embodiment
With reference to the accompanying drawings, in conjunction with the embodiments, in the sewage provide the utility model, the integrated treatment unit of suspended substance, is described in detail.
Embodiment
With reference to Fig. 1, the integrated treatment unit of suspended substance in the sewage of the present embodiment, it comprises air floatation machine 1, filter tank 3, clean water basin 6, back-purge system, described air floatation machine 1 is arranged at front end, the bottom of air floatation machine 1 is provided with air floatation machine water outlet 2, the filter tank 3 that described inside is filled with filtration medium 4 is fixedly installed on below air floatation machine 1, filter tank 3 is connected with air floatation machine 1 by air floatation machine water outlet 2, the end in filter tank 3 is provided with filter tank water outlet 5, described filter tank water outlet 5 is connected with clean water basin 6 by outlet conduit, and be connected with back-purge system bottom filter tank 3, the end of described clean water basin 6 is provided with water port 9.
Described back-purge system comprises Backwash pipeline 8, backwashing pump 7, described Backwash pipeline 8 one end and clean water basin 6, and the other end is connected to bottom filter tank 3, and described backwashing pump 7 is arranged in Backwash pipeline 8, coordinates with Backwash pipeline 8.
First select air floatation machine 1 according to the water yield, calculate the volume in filter tank 3 simultaneously, filter tank 3 is welded on air floatation machine 1 inferoanterior, form an entirety; It is inner that air floatation machine water outlet 2 is placed in filter tank 3, and direct water outlet enters filter tank 3, selects filtration medium 4 as required in filter tank 3, and air floatation machine 1 clearance can reach more than 70%, and water outlet afterwards enters filtering basin 3, and through filtering, removal efficiency can reach more than 90%; Clear water enters clean water basin 6 afterwards, is furnished with Backwash pipeline 8 and backwashing pump 7 between clean water basin 6 and filter tank 3, and a part of clear water is used for back flushing, and remaining clear water is directly sent.
