Specific embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out Clearly and completely describe.Obviously, described embodiment is only a part of embodiment of the utility model, rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment for being obtained, belongs to the scope of the utility model protection.

The purpose of this utility model is to provide in a kind of Vc fermentation industries the reuse means for discarding activated carbon, using discarded Activated carbon is the carrier that environment-protective water processes activated sludge in aerobic aeration tank, not only improves the treatment effeciency of sewage, and is caused Discarded activated carbon is recycled, and economizes on resources.

It is understandable to enable above-mentioned purpose of the present utility model, feature and advantage to become apparent from, below in conjunction with the accompanying drawings and tool The utility model is described in further detail for body embodiment.

Such as Fig. 1, the reuse means that activated carbon is discarded in a kind of Vc fermentation industries is present embodiments provided, including CASS anti- Answer pond 1, water outlet storage box 2, riser fiber filter cloth filter 5, aerator 6, aeration tube 7 and fiber filter cloth outlet pipe 8；It is described perpendicular Piece fiber filter cloth filter 5 is used to be fixed on below the liquid level of CASS reaction tanks 1, and the aerator 6 is arranged on the CASS The bottom of reaction tank 1, one end of the aeration tube 7 connects the aerator 6, and the other end of the aeration tube 7 draws the CASS reactions Pond 1, the riser fiber filter cloth filter 5 is connected by the fiber filter cloth outlet pipe 8 with the water outlet storage box 2. It is put in CASS reaction tanks 1 in Vc fermentation industries and discards activated carbon, by aerator so that activated carbon mixes with sludge, to dirt Water is processed, the sewage of the filtration treatment of riser fiber filter cloth filter 5 by being arranged in CASS reaction tanks 1, is then sent To in water outlet storage box 2, reusing for the process to sewage and exhaust gas active-carbon is completed.

The present embodiment also includes backwash pump 3 and backwash water pipe 4, and described backwash water pipe 4 one end is connected to described The top of riser fiber filter cloth filter 5, the other end of the backwash water pipe 4 is connected under the side of the water outlet storage box 2 Portion, is provided with backwash pump 3 on the backwash water pipe 4, the top of the riser fiber filter cloth filter 5 passes through the fibre Dimension filter cloth outlet pipe 8 is connected with the top of the water outlet storage box 2.The riser fiber filter cloth mesh number of riser fiber filter cloth filter For 200 mesh, by arranging back purge system between riser fiber filter cloth filter 5 and water outlet storage box 2, stored using water outlet Riser fiber filter cloth filter 5 described in the water backwashing of case, to ensure the good by property of filter cloth.

Packed layer is provided between the bottom of the aerator 6 and the CASS reaction tanks 1, to prevent discarded activated carbon from depositing to Space between the bottom of the aerator 6 and the CASS reaction tanks 1；The packed layer material is brick, cement or concrete；Institute It is powdered active carbon to state and discard in Vc fermentation industries activated carbon, and the granularity of the powdered active carbon is 20 to 200 mesh.

In existing CASS reaction tanks 1, aerator 6 is arranged on the bottom of CASS reaction tanks 1, but the bottom of aerator 6 with CASS reaction tanks 1 have the gap of 300mm, and circulating for sludge, the present embodiment is to do due to the discarded activated carbon for adding Go out the activated carbon of powder, discard the density of the density slightly larger than water of activated carbon, can live in aerator aeration process The depositional phenomenon of property charcoal, when discarded activated carbon deposits to the interstitial site of aerator bottom, then cannot CASS reaction tanks 1 again Middle circulation, is so unfavorable for the process of sewage.Therefore, filling is set between the bottom of aerator 6 and the CASS reaction tanks 1 Layer, is filled up in gap with brick, cement or concrete so that the working face of aerator 6 is the bottom surface of whole CASS reaction tanks 1, this Would not there is the situation for being deposited on the bottom gap of aerator 6 in sample activated carbon.

The course of work of the present embodiment：As shown in figure 1, in the CASS reactions equipped with discarded activated carbon and aerobic activated sludge In pond 1, sewage Jing after the air aeration that aeration tube 7 and aerator 6 flow out, the activated sludge for being attached on activated carbon or suspending Process, water outlet Jing riser fiber filter cloths filter 5 and fiber filter cloth outlet pipe 8 enter water outlet storage bin 2.In separated in time Afterwards, it is possible to use the water outlet in water outlet storage bin, via backwashing pump 3 and backwash water pipe 4, to riser fiber filter cloth mistake Filter 5 is backwashed, to ensure the good by property of filter cloth.It is substantially microorganism to sludge, from outward appearance to inner essence including aerobic, simultaneous Three kinds of microorganisms of oxygen and anaerobism, using the discarded activated carbon of powder as activated sludge in the aerobic aeration tank of environment-protective water process Carrier, in the presence of exhaust gas active-carbon, parcel activated carbon grows sludge so that activated carbon becomes the growing carrier of microorganism, Because sludge grows on the activated carbon, its most of microorganism is aerobic, a part of to be and oxygen, the growing environment before comparing, In the case of the supply of identical oxygen, the growth with activated carbon as carrier is rapider, it is thus possible to increase reaction tank for microorganism Sludge concentration, reduce degradation bacteria be lost in, and then improve treatment effeciency.

Sludge is bigger than sludge shape before with the bulk structure that activated carbon is formed as carrier, so can not only cause Riser fiber filter cloth filter 5 easily filters out sludge and obtains the water handled well, and after being also convenient for the replacing of sludge at Reason.

Apply specific case in the utility model to be set forth principle of the present utility model and embodiment, the above The explanation of embodiment is only intended to help and understands method of the present utility model and its core concept；Simultaneously for the one of this area As technical staff, according to thought of the present utility model, will change in specific embodiments and applications.To sum up Described, this specification content should not be construed as to restriction of the present utility model.
