Abstract

The invention provides an unpowered anaerobic apparatus. According to the invention, a pulse generator is arranged on the top of an anaerobic tank; a water inlet pipe, a gas inlet pipe, an a gas outlet pipe are respectively arranged on the upper end of the pulse generator; the water inlet pipe is directly connected with a lift pump; the gas inlet pipe communicates with a biogas chamber in the anaerobic tank; the gas outlet pipe directly communicates with the upper space of the anaerobic tank; a generator connection pipe is arranged on the lower part of the pulse generator, and the generator connection pipe directly communicates with a water distribution pipe at the bottom of the anaerobic tank; a water outlet weir is arranged on the top of the anaerobic tank; and a three-phase separating apparatus is arranged on the upper part inside the anaerobic tank. According to the invention, construction cost and operation cost of a sewage treatment device are effectively reduced, and the removal rate of sewage organic matters is improved. The apparatus provided by the invention is suitable for enterprises which discharge high-concentration organic matter sewage, wherein the enterprises include chemical engineering and pesticide production factories.

Description

Unpowered anaerobic device

Technical field

Patent of the present invention relates to a kind of sewage disposal device, especially relates to a kind of unpowered anaerobic device.

Background technology

In sewage treatment industry, contain the higher sewage of organic substrate concentration for processing at present, what generally adopt is the way that upflow type anaerobic reactor (being called for short UASB) is handled; The deficiency of the main existence of this equipment is: one of which, this equipment water distributor power are mainly from a water pump, if the treatment sewage concentration of suspended matter is high; The power of a water pump does not reach requirement far away; Cause anaerobic pond inside fully to carry out anaerobic reaction, the organism processing rate is very low, only about 30-40%; Its two, if because of water distributor water distribution in the anaerobic pond is not enough or uneven, general two kinds of schemes that adopt are: increase the building height of anaerobic pond, promote the internal-response rate; Another kind of scheme is to increase by one to three water pump, and with the power of enhancing water distributor, but the weak point of above two kinds of schemes is respectively: improve the anaerobic pond building height and equal enterprise to the increasing that environmental protection drops into, increased cost; Increase water pump and equal to expend the more electric power and the water resources of usefulness.Therefore, the upflow type anaerobic reactor of each enterprise's use receives many unfavorable factors at present.

Summary of the invention

Patent of the present invention provides a kind of unpowered anaerobic device to the deficiency of prior art.

For realizing the above object, the technical scheme that patent of the present invention adopts is:

Unpowered anaerobic device is made up of anaerobic pond, water distributor, triphase separator, biogas chamber, lift pump, surge generator, producer pipe connecting, water inlet pipe, inlet pipe, escape pipe, effluent weir jointly; Wherein, Surge generator is installed in the top of anaerobic pond, is respectively equipped with water inlet pipe, inlet pipe and escape pipe in the upper end of surge generator, and water inlet pipe directly links to each other with lift pump; Inlet pipe is connected with the interior biogas chamber of anaerobic pond; Escape pipe passes straight through in the anaerobic pond upper space, and a producer pipe connecting is installed in the surge generator bottom, directly is communicated to the water distributor of anaerobic pond bottom; Effluent weir is located at the top of anaerobic pond, and triphase separator is installed in the anaerobic pond internal upper part according to the height of anaerobic reactor.

The soluble technical problem of patent of the present invention is: during works better, lift pump is evacuated to water in the pulse type reactor, when water level reach a certain height; Can overflow pipe connecting inlet of water begins to flow into the water distributor of anaerobic pond bottom, at this moment; In surge generator, form a negative pressure; Produce siphonage, the water in surge generator flows into water distributor in a large number, to increase the inner upwards thrust of water distributor; The sedimentary suspended sludge layer of anaerobic pond is stirred equably, in anaerobic pond, organism is carried out effecting reaction; Simultaneously, sewage, dirt and biogas separate through triphase separator, and unnecessary part water flows out from effluent weir.The biogas that in anaerobic pond, forms is then delivered to the biogas chamber; When surge generator produces negative pressure because of work; The indoor biogas of biogas gets into surge generator through inlet pipe; Prevent that effectively the air admission anaerobic pond from destroying inner oxygen-free environment, guaranteed the interior removal of anaerobic pond organic matter of sewage 80-90%.

Description of drawings

Fig. 1 is a patent structure synoptic diagram of the present invention.

Wherein: 1, anaerobic pond; 2, water distributor; 3, triphase separator; 4, biogas chamber; 5, lift pump; 6, surge generator; 7, producer pipe connecting; 8, water inlet pipe; 9, inlet pipe; 10, escape pipe; 11, effluent weir;

Embodiment:

As shown in Figure 1, unpowered anaerobic device is made up of anaerobic pond 1, water distributor 2, triphase separator 3, biogas chamber 4, lift pump 5, surge generator 6, producer pipe connecting 7, water inlet pipe 8, inlet pipe 9, escape pipe 10, effluent weir 11 jointly; Wherein, surge generator 6 is installed in the top of anaerobic pond 1, and the size specification of surge generator 6 can be decided according to the volume size of below anaerobic pond 1.Be respectively equipped with water inlet pipe 8, inlet pipe 9 and escape pipe 10 in the upper end of surge generator 6; Water inlet pipe 8 directly links to each other with lift pump 5; Inlet pipe 9 is connected with anaerobic pond interior biogas chamber 41; Escape pipe 10 passes straight through in anaerobic pond 1 upper space, and a producer pipe connecting 7 is installed in surge generator 6 bottoms, directly is communicated to the water distributor 2 of anaerobic pond 1 bottom.Effluent weir 11 is located at the top of anaerobic pond 1, and triphase separator 3 is contained in its middle and upper part according to the height of anaerobic pond 1.During works better, lift pump 5 is evacuated to water in the surge generator 6, when water level reach a certain height; Water producer pipe connecting 7 inlet that can overflow begins to flow into the water distributor 2 of anaerobic pond 1 bottom, at this moment; In surge generator 6, formed a negative pressure, produced siphonage, the water in the surge generator 6 flows into water distributor 2 at short notice in a large number; To increase the upwards thrust of water distributor 2 inside, anaerobic pond 1 sedimentary suspended sludge layer is stirred equably, in the time of in anaerobic pond 1 organism is carried out effecting reaction; Like this, just need not increase the quantity of anaerobic pond 2 building heights and increase lift pump 5.Simultaneously, sewage, dirt and levitation gas are separated through triphase separator 3, and suspended sludge is continued to stay in the anaerobic pond 1, and unnecessary part water flows out from effluent weir 11, and partly gas formation biogas is then collected by biogas chamber 4.When surge generator 6 produces negative pressure because of work; Biogas in the biogas chamber 4 gets in the surge generator 6 through inlet pipe 9; Effectively prevent air admission anaerobic pond 1,, guaranteed anaerobic pond 1 interior effective removal organic matter of sewage in order to avoid destroy inner oxygen-free environment.

Patent of the present invention has reduced the building cost and the running cost of sewage disposal device effectively, has improved the clearance to organic matter of sewage simultaneously, is applicable to chemical industry, high-enriched organics discharge of wastewater enterprises such as pesticide producing factory.
