Description
Technical field
The invention belongs to technical field of water pollution treatment, and in particular to a kind of bypass processing system of black and odorous water and its place
Reason method.
Background technique
There is black smelly and water quality phenomenon not up to standard in urban river, it has also become the common existing pollution in many cities in China is asked
Topic, seriously affects resident living, city image and ecological environment.From the point of view for the treatment of process, traditional river processing system is wrapped again
Include the life of land treatment system (the especially artificial wet land treating system) and oxidation pond and artificial-strengthening type of natural ecology type
Object contact oxidation method, bacteria bed etc..Since there are water temperature, flow and water quality with the biggish spy of Seasonal for river sewage
Point, the existing generally existing poor processing effect of processing method, operating cost is high, and impact resistance is low, cannot synchronize realization denitrogenation
The deficiencies of dephosphorization, it is difficult to reach ideal effect, part river regulation technology is single, water body can not eliminate it is black smelly or reach ground Table V
Class water.
Currently, winter administer black and odorous water water temperature generally at 15 DEG C hereinafter, and water concentration is generally higher than other seasons,
It results in winter operation and is difficult to stably reaching standard；It is limited by the water quality impact and winter low temperature environment shadow of higher ammonia nitrogen and COD concentration
It rings, when the influent COD that the practical influent ammonium concentration of biological aerated filter is higher than 20~25mg/L or biological aerated filter is excessively high
When, the recovery reaching standard time in filter tank has extension after backwash, and heterotroph can become dominant microflora, and the nitrification of ammonia nitrogen is inhibited to make
With.In addition, the ammonia nitrogen concentration of winter raw water is higher than other seasons, when individually being nitrified using aerobic process, it is understood that there may be nothing
Machine basicity concentration is insufficient, influences nitrification efficiency；The general phosphor-removing effect of traditional aeration biofilter is also poor.Due to river periphery
Dykes and dams basis compression strength is poor and can efficiently use that area is small, and since the removal residence time of ammonia nitrogen is longer, causes construction big
Type concrete sewage treatment plant, activated sludge process or contact oxidation method sewage disposal technology are not particularly suited at water course in situ water
Reason；Further, since water course in situ improvement is periodically short, general service is the several years, and concrete sewage processing structures is caused to be difficult
It is generally applicable to river water harnessing；Meanwhile the transport of the limit for height limit for width for also receiving highway of equipment size limits range effects.
Therefore, it is badly in need of that the water quality of high concentration water quality (COD and ammonia nitrogen) and the low temperature environment influence because of current black and odorous water is overcome to be difficult to reach
Mark critical issue, develop a kind of a kind of novel black and odorous water bypass processing system and its processing method, with realize COD in water body,
The pollutants such as ammonia nitrogen, total phosphorus, dissolved oxygen stably reach ground Table IV class water and the above standard.
Summary of the invention

14, the processing method of the bypass processing system of a kind of black and odorous water, which comprises the following steps:
(1) first order: black and odorous water to be processed is promoted to fine fack with No.1 elevator pump and is pre-processed, intercepts and goes
Except fibrous material, the graininess sundries etc. in water body；
(2) second level: treated that water outlet flows into the integrated reciprocal sewage disposal device of turbine cycles for fine fack；Using gas
It proposes muddy water return-flow system and the precipitating muddy water of settling zone is promoted to anoxic pond water inlet end, be mixed together with fine fack pretreatment water outlet
Enter the anoxic pond of the reciprocal sewage disposal device of integrated turbine cycles afterwards, the dissolved oxygen of anoxic pond is 1.0mg/L or less；Anoxic
Denitrifying microorganism in pond is discharged using the labile organic compound carbon source in raw water, stripping reflux muddy water, No. two intermediate water tanks
In nitrate nitrogen carry out denitrification, consumption degradation part COD and BOD and generate basicity；Air lift muddy water reflux ratio be 50%~
100%；After sewage enters multi-stage aerobic pond, the floating stuffing and aeration bubbles of aerobic tank are moved in turbine reciprocation cycle fluidisation,

It on floating stuffing in area, is distributed in dominant microflora, the aerobic heterotroph on floating stuffing further drops to rest COD, BOD
Solution, while biomembrane passes through synchronous nitration and denitrification and acts on removal portion using a large amount of ammonia nitrogens of nitrification degradation on floating stuffing
Divide total nitrogen, water outlet enters sedimentation basin and carries out mud-water separation, and the muddy water of precipitating then passes through air lift muddy water return-flow system and flows back into anoxic
Pond, some residual sludge drain into sludge treating system outside and are handled.By controlling reaction time and dissolved oxygen parameter etc.,
To guarantee the crucial outlet effect of the equipment: removing the COD that 60%~90% always intakes and make to be discharged COD < 80mg/L, complete
The ammoniation process of organic nitrogen；And it removes 30%~60% ammonia nitrogen always intake in water body and makes to be discharged ammonia nitrogen < 20mg/L.
(3) third level: the water outlet of the integrated reciprocal sewage disposal device of turbine cycles enters integrated magnetic-coagulation processing and sets
Standby, hydraulic detention time is 6~30min, and reflux magnetic sludge concentration control is 2g/L~12g/L, removes the major part in water body
Total phosphorus (TP), suspended matter (SS), colloid and organic pollutant promote water transparency；To guarantee the crucial water outlet effect of the equipment
Fruit: 30%~80% COD always intake of removal simultaneously makes to be discharged COD < 50mg/L, and removes the total of 90~95% water inlets in water body
Phosphorus simultaneously makes to be discharged TP < 0.5mg/L, SS < 10mg/L.Magnetic mud is separated from water unit, that treated is remaining for magnetic recovery of circulatory system
Sludge treating system is drained into outside sludge to be handled.
(4) fourth stage: through integrated magnetic-coagulation processing equipment, treated that water outlet flows into No.1 intermediate water tank, and through No. two
It is aerobic except carbon, nitrification, chemical dephosphorization processing processing, water that elevator pump is promoted to integrated aeration boilogical filter tank progress biology aerobic object
The power residence time is 40~80min, and dissolved oxygen is 4.0~6.0mg/L；Under conditions of aerobic, the heterotroph in biomembrane will
Remaining COD removal in water body；Nitrifier on pyrite base biofilter material or weak base base haydite surface in attached biological film is logical
Cross the removal that nitrification completes ammonia nitrogen；The change of Phos occurs in microenvironment for pyrite base biofilter material or weak base base haydite
