Description

Sewage treating apparatus of point-division feed water multilevel biomembrane reactor
Technical field
The invention belongs to sewage disposal, environmental protection technical field, be specifically related to a kind of sewage treating apparatus of point-division feed water multilevel biomembrane reactor.
Technical background
In sewage disposal technology, general process for removing nitrogen and phosphor from sewage is A at present 2/ O and various improved form thereof, it all needs nitrification liquid and mud to reflux equipment to satisfy the requirement of denitrogenation dephosphorizing.In the practical engineering application, this technical process complexity, operation is loaded down with trivial details, running cost is high, and the denitrogenation dephosphorizing effect is difficult to further improve.The biofilm reactor technical development that is used for sewage disposal is rapid, and for example China Patent No. is 200420092487.2, and invention and created name is " an anaerobic aerobic integrated formula static bed biomembrane reactor "; The patent No. is 200420060530.7, invention and created name is that " biofilm reactor that is used for sewage disposal " and the patent No. are 200410013159.3, and invention and created name discloses the biofilm reactor of different structure for priorities such as " the carrier circulating biological treatment processs that is used for sewage disposal ".The above two are single-stage reactor, have more differently with the multistage separated by spaces of this reactor, though its compact construction, single-stage reactor is unfavorable for the structure of the superior microorganism flora growing environment that various effects are different, and treatment efficiency is lower; The latter and this reactor have more differently textural, and there is the high efficiency filter settling region in this reactor.In addition, there is single-point water inlet denitrifying carbon source deficiency in the latter, and denitrification effect is undesirable, and the big problem of chemical dephosphorization sludge quantity.At present, the domestic and international report of not seeing as yet relevant for sewage treating apparatus of point-division feed water multilevel biomembrane reactor.
Summary of the invention
At prior art, especially general denitrogenation dephosphorizing reactor above shortcomings, the purpose of this invention is to provide a kind of sewage treating apparatus of point-division feed water multilevel biomembrane reactor, save the mixed solution and the mud return-flow system of denitrification dephosphorization system complexity, reduce the energy consumption in the sewage treatment process, reduce surplus sludge volume, simplify treatment process, improve the water treatment efficiency, reduce and take up an area of.
The object of the present invention is achieved like this: a kind of sewage treating apparatus of point-division feed water multilevel biomembrane reactor, comprise pond body, water inlet pipe, rising pipe and shore pipe, it is characterized in that vertically being provided with in the body of described pond N piece dividing plate, the pond body is divided into the placed in-line reaction tank of N+1 level, the alternate connection in bottom successively of each adjacent reaction pond with top; Wherein, preceding N-1 level adopts the anaerobic-aerobic alternate run, establishes the medium-soft combined stuffing in each pond, and the N level is an aerobic reactor zone, in establish the medium-soft combined stuffing, the N+1 level is the filtering-depositing district, in establish the rich calcium filler of rich iron; The top that described water inlet pipe is located at the pond body is communicated with the water-in in preceding N-1 order reaction pond respectively, takes branch to supply water; Rising pipe is picked out by the top in N+1 order reaction pond; Underwater aeration device is arranged in bottom, N order reaction pond before described, and backwash tube is arranged in bottom, N+1 order reaction pond, and each bottom, pond is equipped with shore pipe, can be regularly from each reaction tank depositing separation area spoil disposal.
The value of N is 3-10, and the value of N increases according to the increase of treatment sewage concentration.
Compared to existing technology, the present invention has following characteristics:
1. anti impulsion load, reactor for treatment usefulness height.
This treatment facility is owing to adopt the biomembrane process mode, and reactor has higher microorganism concn, and actual sludge loading is reduced, so anti impulsion load and adaptability are strong; By the medium-soft combined stuffing is set in reactor, and the suitable dissolved oxygen levels of control, can form abundant aerobic-anaerobic microenvironment in that microbial film is inner, be easy to realize synchronous nitration denitrification denitrogenation efficiently.Simultaneously, the dividing plate subregion is set in reactor, carries out the aerobic-anoxic alternate run, and adopt the supply of the method reinforcement carbon source of branch water inlet, avoided the insufficient problem of denitrifying carbon source, for the biomembrance process efficient dephosphorization has made up good environment by each district.In addition, N+1 level filtering-depositing district utilizes the rich calcium filler of rich iron to strengthen dephosphorization, has guaranteed that treater obtains high processing usefulness.
2. need not to establish special mixed solution and mud reflux, operation energy consumption is low.
Usually the energy consumption cost in the sewage treatment process accounts for the large percentage of its running cost, and cutting down the consumption of energy is the key point that reduces running cost.The energy consumption of general sewage treatment process is mainly used in lifting, aeration and the nitrification liquid of sewage, the backflow of mud.This treatment facility can be realized synchronous nitration and denitrification efficiently by the medium-soft combined stuffing is set in reactor, saved the mixed-liquor return system.Simultaneously, in preceding N-1 order reaction pond, carry out the aerobic-anoxic alternate run,, strengthened biological dephosphorize denitrification, saved the mud return-flow system of general dephosphorization system for the biomembrance process efficient dephosphorization has made up good environment.In addition, adopt biomembrance process to make up this treatment unit, saved general reactor required whipping device in anaerobic phosphorus release and anoxic denitrification process, so this treatment facility has efficient feature.
3. surplus sludge volume is few.
In treatment facility, establish the medium-soft combined stuffing and reduced sludge yield, adopt molten born of the same parents of mud and microfauna sludge predation technology to strengthen the decrement of mud simultaneously by plural serial stage microbial film and longer microorganism food chain thereof.
4. low, convenient management is lacked, takes up an area of less, is invested in technical process.
Technique units such as this treatment facility collection biological dephosphorize denitrification, mud decrement, precipitation are one, utilize reactor wall altogether, have significantly reduced the investment and the occupation of land of equipment.The Inlet and outlet water Continuous Flow has the characteristics of convenient operation and management.
