Abstract
The invention belongs to the field of agricultural environmental protection, and relates to a push flow type anaerobic bioreactor for sewage treatment. The push flow type anaerobic bioreactor is realized through the following approaches: conveying a feed liquid after pretreatment to a temperature-increasing tank to be heated, conveying the heated feed liquid into a feeding pool through an overflow pipe, and then conveying the feed liquid to the inside of a reactor from a feed opening in the feeding pool so that the feed liquid is sufficiently contacted with a covering film carrier, pelagic anaerobes and activated sludge in the reactor and then is pushed to flow among hydraulic pressure, the supernatant fluid is discharged out through the overflow pipe, and the sludge is taken away by a pump dredger. The anaerobic bioreactor has the following advantages that the temperature-increasing tank improves the utilization rate of the feed liquid, the processes of acidification, the hydrolysis and methane production for the anaerobic reaction are improved, the detention period of the feed liquid is shortened, and the treating capability and the treating effect of a system are improved; besides, the design of the covering film carrier and a sludge-blocking wall increases the amount of anaerobes in the reactor and promote the conversion efficiency of the organic substances in the feed liquid.
Description
[technical field]
The invention belongs to field of agricultural environmental protection, relate to a kind of pulling flow type anaerobe reactor that is used for sewage disposal.
[background technology]
Quickening along with China's new countryside construction paces, the fast development of intensive pig production industry, culturing a large amount of waste water that produce in the evolution far can not be dissolved by the soil naturally, atmosphere, soil, underground water and other receiving water body have all been constituted serious pollution threat, and the aquaculture pollution problem has caused the great attention of country.But pig industry belongs to the small profits industry, thereby it is not too large to have limited the sewage disposal investment ability, and this just needs less investment, treatment effect is good, running cost is low, the sewage water treatment method that also has certain economic benefit.
Based on the sewage disposal technology of aerobic activated sludge process, though the pollutants removal rate height, floor space is big, infrastructure investment and working cost height; And Anaerobic Microbiological Treatment Technology is because anti-organic loading ability height; Do not need the aeration oxygen supply, save process cost; Sludge yield is few and be easy to handle; Less energy-consumption; The biogas that produces in the anaerobic process can be used as clean energy again and reclaims, and is used, and becomes the power-saving technology of domestic and international common concern.
Microbic activity and quantity directly affect the purification efficiency of reactor in the anaerobic biological reactor, and the height of temperature directly affects microbic activity, quantity and generation cycle in the reactor.In general, under the identical situation of other processing condition, in 0 ℃～60 ℃ scopes, 10 ℃ of the every risings of temperature, speed of response just approximately increases by 2～4 times.Therefore improve the interior fermentation raw material temperature of reactor and will effectively improve the reaction efficiency of system to optimum range.
Pulling flow type anaerobe reactor through improvement of the present invention, be aided with sun power economic benefits and social benefits heating technology and overlay film carrier technique, help to improve the fermentation raw material temperature, promote the activity of anaerobion, obviously accelerate acidifying, hydrolysis and the product methane process of anaerobic reaction, shorten feed liquid residence time, improved the processing power and the treatment effect of system.
[summary of the invention]
Pulling flow type anaerobe reactor of the present invention, realize by following approach, pretreated feed liquid is delivered to and heats groove, heat, the feed liquid after heating enters the charging pond by upflow tube, changes inside reactor over to by the opening for feed in the charging pond again, overlay film carrier in feed liquid and the reactor, swim anaerobion and active sludge fully contact, be pushed then and flow to water pressure house, supernatant liquor is discharged by upflow tube, and mud is then taken away by silt pumping car.
Described pulling flow type anaerobe reactor is provided with return-flow system at water pressure house, and discontinuity is back to the charging pond to the feed liquid that is rich in anaerobion after fermenting.
Described pulling flow type anaerobe reactor, the reactor periphery is built the greenhouse or is inserted heating pipeline at inside reactor, feed liquid is forced to heat, help lend some impetus to the activity of anerobe like this, obviously improve acidifying, hydrolysis and the product methane process of anaerobic reaction, shorten feed liquid residence time, improve the processing power and the treatment effect of system.
The overlay film carrier is with steel pipe, reinforcing bar or UPVC hard tube hard material construction framework, adopts the two-sided non-woven fabrics of porous corrosion resistant, non-woven cotton or analogous material as attachment, the unit module group that together is built into frame fixation.
Principle of work of the present invention:
After system starts, the pretreated feed liquid of process is delivered to by lift pump and heats groove, heat the euphotic cover plate that the top of groove has the high light transmissive material of sunlight board or glass or other to make, euphotic cover plate and heating between the groove is sealed and matched, heat shedding of sharp aroma in the groove to stop, feed liquid is detained for some time in heating groove, it is that the feed liquid that heats in the groove heats that the sunlight that the greenhouse is entered in heat of collecting in the heliogreenhouse and direct projection can see through euphotic cover plate, feed liquid after heating can be by upflow tube from flowing into the charging pond, and by feed-pipe inflow reactor inside, heating the mud that with the passing of time deposits in the groove can discharge by shore pipe, enter on the mode and overlay film carrier of feed liquid with plug-flow of reactor, in the mud of bottom with feed liquid in anaerobion fully contact and carry out anaerobically fermenting, in the process that microorganism breeds from generation to generation, organic matter in the feed liquid is decomposed and transforms, remove CODcr and suspended substance to reach, change the purpose of organonitrogen and organophosphorus form; Reacted feed liquid, is discharged by water outlet to water pressure house then by new feed liquid plug-flow.
In addition, at water pressure house return-flow system is set, discontinuity is back to the charging pond to the feed liquid that is rich in anaerobion after fermenting, and promotes anaerobion and newly advances fully contacting of raw material, improves the Degradation and Transformation efficient of reactor; Also can optionally insert heating pipeline as required at inside reactor, feed liquid is forced to heat, help lend some impetus to the activity of anerobe like this, obviously improve acidifying, hydrolysis and the product methane process of anaerobic reaction, shorten feed liquid residence time, improve the processing power and the treatment effect of system.
Advantage of the present invention and positively effect:
1. heating groove will help feed liquid is highly improved to energy utilization ratio;
2. feed liquid can effectively be utilized sun power or other measure of heating to heat to heat, help lend some impetus to the activity of anerobe, obviously improve acidifying, hydrolysis and the product methane process of anaerobic reaction, shorten feed liquid residence time, improve the processing power and the treatment effect of system.
3. the introducing of overlay film carrier and retaining mud wall in the reactor has promoted the anaerobion quantity in the reactor, promotes organic transformation efficiency in the feed liquid.
4. in the water pressure house return-flow system is set, discontinuity is back to the charging pond to the feed liquid supernatant liquor after fermenting, and the promotion anaerobion fully contacts with fresh feed liquid, improves the Degradation and Transformation efficient of reactor.
5. as heliogreenhouse of the peripheral construction of reactor, make full use of sun power, saved the energy resource supply of system.
