Abstract

The utility model relates to a biological sewage treatment device which comprises a biological membrane bed microbial carrier arranged in a sewage fluid channel, and is characterized in that the biological membrane bed microbial carrier is a silk yarn bundle which is vertically arranged; the filling rate of silk yarn in the cross section of the fluid channel filled with the silk yarn is 0.5-12%; the sectional area of the silk yarn used for forming the silk yarn bundle is 0.0008-7mm<2>. Compared with the prior art, the biological sewage treatment device has the advantage that the biological membrane bed microbial carrier is guaranteed to have stable specific surface area which is not easily damaged.

Description

A kind of biology sewage treatment equipment

Technical field:

The utility model relates to a kind of sewage water treatment method and device.

Background technology:

It is that sewage is injected in biofilm bed that existing biological sewage is processed, by the microorganism in biofilm bed, the pollutant removal in sewage is realized, this kind of technology, needing the problem solving is the specific surface area that how to promote as much as possible biofilm bed microbe carrier.Prior art microbe carrier has the material of porous by employing, as steel wire lump, the large specific surface area having by hole promotes the specific surface area of the bio-carrier of biofilm bed.Because the size in the hole of porous material is changeless often, like this, microbial film is just easy to hole to stop up, causing sewage to pass through resistance significantly rises, even under the effect of high sewage hydraulic pressure, also be not easy to get through the cavity of obstruction, like this, sewage just can only pass through from the gap between the relatively little steel wire lump of resistance, reduced the treatment effect of sewage, after for some time, more the obstruction because of hole sharply declines the specific surface area of biofilm bed, and the sewage treatment capacity of biofilm bed is declined to a great extent.For this reason, the inventor adopts ball of yarn to carry out instead of steel pompon, utilize ball of yarn under hydraulic pressure, the characteristic that silk thread easily scatters, overcomes the shortcoming that existing steel wire lump technology is not easy to scatter because of the mutual compact winding of silk thread, even so, owing to forming the silk thread of ball of yarn, be also to have bending to be to a certain degree wound around, and during sewage disposal, the flow velocity of water is slow often, the silk thread that hydraulic pressure is not easy bending to be wound around breaks up, to avoid the gap between silk thread to be sealed by microbial film.

Summary of the invention:

Goal of the invention of the present utility model is to provide a kind of and guarantees that biofilm bed microbe carrier has the stable biology sewage treatment equipment that is not easy destroyed specific surface area.

The biological sewage of the present utility model side of processing device is to realize like this, comprise the biofilm bed microbe carrier being arranged in sewage fluid channel, its special feature is that biofilm bed microbe carrier is the vertical silk thread bundle arranging, in the cross section of fluid channel that is filled with silk thread, the filling ratio of silk thread is 0.5%-12%, and the sectional area of the silk thread of formation silk thread bundle is at 0.0008mm ²-7mm ².

Fluid channel is vertically disposed socket shape passage, is vertically provided with silk thread bundle in fluid channel.

Or, fluid channel arranged transversely, the water (flow) direction of the fluid channel of arranged transversely arranges silk thread bundle more than a row.

Compared with the prior art the utility model, has advantages of that the biofilm bed of assurance microbe carrier has the stable destroyed specific surface area that is not easy.

Accompanying drawing explanation:

Fig. 1 is the structural representation of the utility model embodiment 1;

Fig. 2 is the structural representation of the utility model embodiment 2;

Fig. 3 is that the A of silk thread bundle of Fig. 2 is to view;

Fig. 4 is the B-B sectional view of Fig. 1;

Fig. 5 is Fig. 1 C point lateral plan.

Embodiment:

Now in conjunction with the accompanying drawings and embodiments the utility model is described in further detail:

Biology sewage treatment equipment embodiment 1: as shown in Fig. 1,4, comprise the biofilm bed microbe carrier 4 being arranged on in the sewage fluid channel 3 of fluid inlet 1 and outlet 2, its special feature be biofilm bed microbe carrier 4 be vertically arranged on support 5 silk thread bundle 6, in the cross section of fluid channel 3 that is filled with silk thread bundle 6, the filling ratio of silk thread is 0.5%-12%, and the sectional area of the silk thread of formation silk thread bundle 6 is at 0.0008mm ²-7mm ².Fluid channel 3 is vertically disposed socket shape passages, the interior silk thread bundle 6 that is vertically provided with of fluid channel 3.Certainly, form the silk thread of silk thread bundle due to more tiny, therefore yet cross winding to some extent each other, still, is not that bending is wound around, and therefore, is easy to unclamp between silk thread.

As shown in Figure 5, silk thread bundle 6 strides across support 5 and fixes by fixed link above.

When biological sewage is processed, on several synnema lines 6 of the biology sewage treatment equipment of embodiment 1, culturing micro-organisms film is to form biofilm bed, then sewage up flows below fluid channel 3, and the microbial film being grown on the silk thread of silk thread bundle 6 is processed the sewage of flowing through.

Biology sewage treatment equipment embodiment 2: as shown in Figure 2, the present embodiment is on the basis of embodiment 1, fluid channel 3 arranged transverselys (can be also river course), the water (flow) direction of the fluid channel 3 of arranged transversely arranges the silk thread bundle 6 on bracing frame 7 that an is arranged on more than row.

When biological sewage is processed, on the silk thread bundle of the biology sewage treatment equipment of embodiment 2, culturing micro-organisms film is to form biofilm bed, and sewage flows facing to silk thread bundle 6 is positive, and the microbial film being grown on the silk thread of silk thread bundle 6 is processed the sewage of flowing through.
