Description

Integral type high concentrated organic wastewater treatment unit
Technical field:
The present invention relates to a kind of wastewater treatment equipment, relate in particular to a kind of wastewater treatment equipment of integral type, be applicable to the processing of high concentrated organic wastewater.
Background technology:
At present, in high concentrated organic wastewater is handled, directly adopt anaerobism or aerobic biological treatment process all to be difficult to obtain the ideal effect, utilize the acidication section of anaerobic process then more and more to be paid attention to as the A/O technology of front-end processing.Along with to the deepening continuously and the develop rapidly of various high efficiency anaerobic reactors of anaerobic digestion mechanism research, the Anaerobic Microbiological Treatment Technology of waste water has become one of core technology of resource and environment protection.UASB be the people such as Lettinga of Dutch Wageningen agriculture university in a kind of high efficiency anaerobic reactor of the exploitation seventies in 20th century, be widely used in production practice at present.The success of UASB has greatly promoted the development of other high efficiency anaerobic reactor, baffling type anaerobic reactor (Anaerobic Baffled Reactor, be called for short ABR) a kind of new and effective anaerobic reactor on the UASB basis, developed just, it have shortly flow, do not stop up, need not to stir, the easy characteristics of startup.
The ABR reactor is a kind of new high-efficiency anaerobic reactor that is proposed in early 1980s by the people such as McCarty of U.S. Stanford university.Some vertical flow deflectors are set in this reactor, reactor is separated into placed in-line several reaction, each reaction chamber can be regarded a relatively independent upflow sludge blanket system (Upflow sludge bed is called for short USB) as.The cellular structure of ABR reactor uniqueness and pulling flow type fluidised form make and can inoculate and culture out and flow to the sewage quality in this reaction chamber, the microflora that envrionment conditions adapts in each reaction chamber, thereby cause anaerobic reaction produce acid mutually and the product methane journey of handing down separated, make the ABR reactor on overall performance, be equivalent to a diphasic anaerobic treatment system.It is generally acknowledged that diphasic anaerobic technique is by producing the acid phase and producing separating of methane phase, two big class anaerobic bacteria floras can be grown under the optimum envrionment conditions separately, help giving full play to the activity of anaerobic bacteria flora, improve the treatment effect of system and the stability of operation.A weak point of ABR reactor is that system's effluent quality is relatively poor, and needing usually could qualified discharge through subsequent disposal.
The Cheng Kaiying of the Zhongshan city refined environment-friendly engineering of perseverance company and Liao Geyu handle the food dressing high concentrated organic wastewater with aerobic reaction tank and anaerobic reation pool (ABR-SBR) combination process July calendar year 2001, and every index of handling the back water outlet reaches the primary standard standard of G B 8978-1996.The Xu Yudong of Fujian Province environment protection designing institute; in May, 2002; water quality characteristics at woollen blanket waste water; adopt coagulating sedimentation-anaerobic baffle plate reaction tank-two-stage aerobic biochemical process to handle woollen blanket waste water; show through engineering practice; this technology advanced person, efficient, stable, water outlet can reach " textile dyeing and finishing industrial water pollution thing emission standard " (GB42 87-92) primary standard.But, the ABR-SBR combination process is because the water outlet of ABR reactor pumps into water collecting basin through pump, the water outlet of water collecting basin pumps into sbr reactor pond or biological contact oxidation pond through pump, the water outlet of sbr reactor pond or biological contact oxidation pond pumps into the coagulating sedimentation sand filter through pump, the consumption of pump and water pipe is many like this, make the structure of system numerous and diverse, floor space is big, and the energy consumption during system's operation is many, thereby has increased the cost of system greatly.
Summary of the invention:
The object of the present invention is to provide a kind of efficient, energy-conservation, take up an area of less, the high concentrated organic wastewater treatment unit of simple in structure, integral type that cost is low.
Purpose of the present invention realizes by following measure:
A kind of integral type high concentrated organic wastewater treatment unit, the anaerobic reaction chamber, aerobic reaction chamber and the settling chamber that are separated into by traverse baffle form, and bind in wherein said anaerobic reaction chamber, and described settling tank, aerobic reaction chamber are uncovered.
Described aerobic reaction chamber is provided with venting port, and the settling chamber is provided with sewage draining exit, and the aerobic reaction chamber is provided with inflation inlet.
Described flow deflector is perpendicular to above-mentioned each reaction chamber.
Described anaerobic reaction chamber is 3-5, and described settling chamber is at least 2.
Described each reaction chamber is followed successively by placed in-line anaerobic reaction chamber, settling chamber, aerobic reaction chamber, settling chamber along water (flow) direction.
Described aerobic reaction chamber is upflowing, downflow system reaction chamber.
Described anaerobic reaction chamber, aerobic reaction chamber, settling tank are rectangular parallelepiped.
The big I of above-mentioned each reaction chamber is specifically determined according to the concentration and the hydraulic load of former water.
The present invention compared with prior art has the following advantages:
1, efficient: the cellular structure of uniqueness of the present invention and pulling flow type fluidised form make and can inoculate and culture out and flow to the sewage quality in this reaction chamber, the microflora that envrionment conditions adapts in each reaction chamber, help giving full play to the activity of anaerobic bacteria flora, the treatment effect of raising system and the stability of operation, it is relatively poor to have overcome ABR reactive system effluent quality, needs the shortcoming through subsequent disposal ability qualified discharge usually.The total clearance that experimental results show that integral type high concentrated organic wastewater treatment unit of the present invention is 94.89%, and water outlet reaches the water quality requirement of Dry crop in " agricultural irrigation water quality standard ".
2, energy-conservation: the present invention adopt vertical traverse baffle with reactor be separated into the ABR reactor, the settling tank that catchments, sbr reactor pond or biological contact oxidation pond, settling tank, make it into as a whole, not only simplified system architecture, reduced floor space, and at least three pumps of saving and corresponding water pipe, reduce the cost of system, saved the energy consumption of system.
3, anti-bursting by freezing: the used pipeline of the present invention is few, and waste water flows into next reaction chamber from a reaction chamber by flow deflector, has effectively avoided the heat radiation of water pipe, can prevent the bursting by freezing of water pipe in winter.
4, be adapted to seasonality or biological wastewater treatment that batch production produced: in each chamber of reactor of the present invention, difference start time of the different microorganisms population that is survived under the varying environment.Microorganism culturing in the anaerobic room is the slowest, but anaerobic species can keep its biological activity and good sedimentation function more than at least one year under the condition that stop to supply with waste water and nutrition.So after this reactor start-up was good, when being no more than 1 year pitch time, biological activity was recovered when recovering to supply with waste water thereupon.
5, the toxic substance in impact load of the present invention and the water inlet has good buffering adaptive faculty, but heavy-duty service.
